Synthetic Organic Chemistry

Synthesis and Bioassay of Novel Heterocycles

Heterocycles, the largest classical division of organic chemistry are of immense importance biologically, industrially and indeed to that functioning of any developed human society. Over the years five and six membered heterocycles, viz., barbituric acid, thiobarbituric acid, oxadiazole and thiadiazole derivatives have emerged as an interesting class of compounds with wide range of applications in pharmaceutical chemistry. Ketene dithioacetals are versatile synthons for the development of a wide variety of heterocyclic systems. The reactivity of ketene dithiolates in the presence of different equivalents of sodium ethoxide was studied. We have developed simple and efficient route for the synthesis of previously unreported bis heterocycles from ketene dithiolates. 2-(Bis((5-aryl-1,3,4-oxadiazol-2-yl)methylthio)methylene)-malononitriles and 2-(bis((5-aryl-1,3,4-thiadiazol-2-yl)methylthio)methylene)-malononitriles were prepared by the reaction of malononitrile with carbon disulfide and 5-aryl-2-(chloromethyl)-1,3,4-oxadiazoles / 5-aryl-2-(chloromethyl)-1,3,4-thiadiazoles. The preliminary antimicrobial and antioxidant activities of the lead compounds were assayed.

A new class of trisheterocyclic systems, bisoxadiazolyl/ bisthiadiazolyl pyrimidinetriones/ thioxopyrimidinediones were prepared by the condensation of barbituric acid and thiobarbituric acid with carbon disulfide under base catalysis followed by treatment with 2-chloromethyl-5-aryloxadiazoles and 2-chloromethyl-5-arylthiadiazoles. The antimicrobial studies of trisheterocycles revealed that compounds having thioxopyrimidinedione in combination with bisthiadiazole unit exhibited high activity. The reaction of barbituric acid / thiobarbituric acid with CS2 followed by treatment with ethyl bromoacetate led to directly Dieckmann cyclized product. However, with phenacyl bromide bisalkylation took place which were used as synthons to develop a new class of olefins by Knovenagel condensation with different araldehydes.

A simple dipolarophile, bis(styryl)sulfone was exploited to get a new and novel sulfone linked bis heterocycles viz., pyrroles in combination with pyrazolines and isoxazolines adopting simple and versatile 1,3-dipolar cycloaddition methodology. Besides these, a new class of oxadiazoles were prepared by treating aminosulfonylacetic acids with different carboxylic acid hydrazides. Interconversion of oxadiazoles to thiadiazoles was carried out with thiourea. The compounds were screened for antimicrobial and antioxidant activities. Apart from these, sulfone linked pyrrolyl oxazolines and thiazolines were synthesized from E-arylsulfonylethenesulfonylacetic acid methyl ester and studied their antimicrobial and antioxidant activities.

A study on biologically potent heterocycles

A wide variety of heterocyclic systems have been explored for developing pharmaceutically important molecules. Amongst them, five membered heterocycles viz., pyrroles, pyrazoles, 1,3,4-oxadiazoles, 1,3,4-thiadiazoles and 1,2,4-triazoles are important class of heterocyclic compounds. The wide spread use of them as scaffold in medicinal chemistry establishes these moieties as a member of the privileged structures class. In view of these, we have prepared a new class of bis heterocycles pyrrolyl/pyrazolyl arylaminosulfonylmethyl 1,3,4-oxadiazoles, 1,3,4-thiadiazoles and 1,2,4-triazoles from synthetically vulnerable intermediates arylaminosulfonylacetic acid hydrazide and Z-styrylsulfonylacetic acid and studied their antimicrobial activities. The presence of arylaminosulfonylmethyl group enhances the antimicrobial activity when compared with other bis heterocycles.

The sulfonyl activated olefin, E-1-(arylsulfonylethylsulfonyl)-2-arylethene was used as synthon to develop a new class of pyrrole and pyrazole derivatives by 1,3-dipolar cycloaddition of TosMIC and diazomethane. Thus, a new class of heterocycles, 3-(arylsulfonylethylsulfonyl)-4-aryl-1H-pyrrole, 3-(arylsulfonylethylsulfonyl)-4,5-dihydro-4-aryl-1H-pyrazole and 3-(arylsulfonylethylsulfonyl)-4-aryl-1H-pyrazole were prepared from the Michael acceptor, E-1-(arylsulfonylethylsulfonyl)-2-arylethene adopting simple, facile and well-versed synthetic methodologies.

Furthermore, Some new 2-(arylsulfonylethylsulfonylmethyl)-5-(2-chlorophenyl)-1,3,4-oxadiazoles / thiadiazoles / triazoles and 2-(benzylsulfonylethylsulfonylmethyl)-5-(2-chlorophenyl)-1,3,4-oxadiazole / thiadiazoles / triazoles were prepared by exploiting carbomethoxy functionality in arylsulfonylethylsulfonylacetic acid methyl ester and benzylsulfonylethylsulfonylacetic acid methyl ester adopting simple and well versed methodologies. All the lead compounds were screened for antioxidant activity. The benzylsulfonylethylsulfonylmethyl substituted oxazdiazoles displayed pronounced antioxidant activity.

Electron transport proteins, NMR analysis of 3D protein structure, biosynthesis of novel tetrapyrroles and Polysaccarides

Research comprises two main areas: the structure and mechanism of operation of electron transport proteins; the structure and biosynthesis of unusual tetrapyrroles. High resolution NMR techniques in combination with molecular dynamics and energy minimization are being applied to determine structure for cytochromes and other electron transport proteins. The wallpaper on this page is a small portion of a two-dimensional COSY spectrum of cyt c-551 showing the spin-coupling interactions between aromatic protons. In the second main area, chemical spectroscopy (NMR, mass spectrometry, UV-visible spectroscopy, FT-IR) is applied to determine the structure of unusual porphyrins that are found as the active site prosthetic group in some enzymes. The biosynthetic pathway of these molecules is being explored by the use of stable isotope enrichment of presumed precursors, and by the isolation and characterization of natural metabolic precursors.

Synthesis of Nano particles

Field of nanotechnology is the most active area of research in modern materials science. Though there are many chemical as well as physical methods, green synthesis of nanomaterials is the most emerging method of synthesis. We report the synthesis of antibacterial silver nanoparticles (AgNPs) using leaf broth of medicinal herb, Ocimum Species(Tulsi). The synthesized AgNPshave been characterized by UV-Vis spectroscopy, transmission electron microscopy (TEM), and X-ray diffractometry. The mean particle of synthesized NPs was found to be 18 nm, as conformed by TEM. The qualitative assessment of reducing potential of leafextract has also been carried out which indicated presence of significant amount of reducing entities. FTIR analysis revealed that the AgNPs were tabilized by eugenols, terpenes, and other aromatic compounds present in the extract. uch AgNPs stabilized byTulsi leaf extract were found to have enhanced antimicrobial activity against well-known pathogenic strains, namely Staphylococcusaureus and E. coli.

Enjoys challenging and collaborative research

Synthesis,characterization and Electrochemical behaviour of chalcones,Isoxazolins,Pyrazolins,Drugs and pesticides of using D.C.Polarography,Differential pulse polarography,Cyclic Voltammetry, sensitive differential pulse adsorptive stripping voltammetric method

In the present investigation also deals with the electrochemical reduction behaviour of unsaturated ketone groups have been studied choosing 4-hydroxy substituted chalcones, 2,4-dihydroxy substituted chalcones, 2,5-dihydroxy substituted chalcones, and 2,6- dihydroxy substituted chalcones. These studies have been carried out using the techniques of D.C. polarography and Differential Pulse polarography. Millicoulometry has been employed to determine the number of electrons involved in the electrode process and 0.1 M DMSO containing TBFP buffer used as supporting electrolyte.

Under the different experimental conditions described, the reduction of selected a, b – unsaturated ketone group compounds are found to give rise to different number of waves/ peaks depending on the pH of the supporting electrolyte as well as the compounds studied. 4-hydroxy substituted chalcones such as 3-(2-chlorophenyl)-1-(4-hydroxyphenyl)prop-1-en-1-one and 3-(4-chlorophenyl)-1-(-4-hydroxyphenyl)prop-2-en-1-one are found to give two step reduction waves / peaks corresponding to the reduction of a,b-unsaturated ketone to saturated ketone with uptake of two electrons in 0.1M DMSO containing TBFP supporting electrolyte with DC polarography technique. (4-hydroxy)-3-(3-nitrophenyl) prop-2-en-1-one has been observed to be three step reduction waves /peaks in the above supporting electrolyte in acidic media. This three waves / peaks are attributed to reduction of nitro group to hydroxyl amine by addition of four-electron process and a,b-unsaturated ketone group to saturated ketone by addition of two electron process. 2,4-dihydroxy substituted chalcones such as 3-(2-chlorophenyl)-1-(2,4-hydroxy phenyl)prop-2-en-1-one, 1-(2,4- dihydroxyphenyl)-3-(4-hydroxyphenyl) prop -2-en-1-one and 1-(2,4- dihydroxyphenyl) -3-(3-hydroxy phenyl)prop-2-en-1-one are found to give two step reduction waves / peaks and is attributed to the reduction of a,b- unsatured ketone to saturated ketone with the uptake of two electron in above supporting electrolyte with D.C.Polarography. 1-(2,4- dihydroxy phenyl)-3-(4-nitrophenyl)prop-2-en-1-one has observed to be three step reduction waves/ peaks in acidic media. This three step reduction wave/ peak is attributed to reduction of nitro group to hydroxylamine by addition of four electron process and a, b-unsaturated ketone to saturated ketone by addition two electrons.

2,5-dihydroxy substituted chalcones such as 3-(2- chlorophenyl)-1-(2,5-dihydroxyphenyl)prop-2-en-1-one and 3-(4- chlorophenyl)-1-(2,5-dihydroxyphenyl) prop-2-en-1-one are found to give two step reduction waves / peaks and are attributed to the reduction of a,b-unsaturated ketone group to saturated ketone by addition of two electrons. 1-(2,5-dihydroxyphenyl)-3-(3-nitrophenyl)prop-2-en-1-one is found to give three step reduction waves / peaks and are attributed to the reduction of nitro group to hydroxyl amine by addition of four electrons and a,b-un saturated ketone group to saturated ketone by addition of two electrons.

2,6-dihydroxy substituted chalcones such as 3-(4- chlorophenyl)-1-(2,6-hydroxyphenyl) prop-2-en-1-one, 1-(2,6- dihydroxyphenyl)-3-(4-hydroxy phenyl) prop-2-en-1-one and 1-(2,6-dihydroxyphenyl)-3-(3-hydroxyphenyl) prop-2-en-1-one are found to give two step reduction waves/ peaks and are attributed to reduction of a,b-unsaturated ketones by addition of two electron process. 1-(2,6- dihydroxy phenyl)-3-(4-nitrophenyl)prop-2-en-1-one compound is found to give three step reduction waves / peaks and are attributed to reduction of nitro group to hydroxyl amine by addition of four electrons and a,b-unsaturated ketone to saturated ketone by two electron addition. In all compounds the reduction become easier facilitates the radical formation.

In the entire compounds studied the shift of peak potential towards negative values indicates the reduction process involving the electroactive species studied to be irreversible. The irreversible nature of the electrode process are indicated from log plot analysis and Tomes' criterion in D.C. polarography and differential pulse polarography data . Proton involvement is also evidenced from the plots of E vs. pH and Em vs. pH. Based on the results obtained, the following general reduction mechanism may be assigned for a,b-unsaturated ketones at pH 2.0 to 6.0. It is a well known fact that 0.1 M DMSO containing TBFP buffer system and the pH of the buffer influence the ease of reduction of the compounds containing the a,b-unsaturated group in the chalcones derivatives are found to proceed irreversiblyat mercury drop electrode. This is evidenced from the disobedience of Tomes’ criterion, log-plot analysis, shift of reduction potentials towards more negative values with increase in the concentration of electroactive species and scan rate. The plots of id vs h, im vs. t2/3 are observed to be linear and passing through the origin in each of the supporting electrolytes employed indicating adsorption free and diffusion controlled nature of the electrode process. The half wave and peak potential values of all the compounds are found to be pH dependent, indicating proton involvement in the electrode process. Possibility of increase in the pH value, increase the disassociation constant of the protonated species and these factors affect the protonation rate and consequently the E and Em values of the reduction waves / peaks get shifted to more negative potentials. The proton involvement in the reduction process is also evidenced from the E vs. pH and Em vs. pH plots.

The kinetic parameters such as transfer coefficient, diffusion coefficient and heterogeneous forward rate constant values have been evaluated by making use of above techniques. In general, the diffusion coefficient values are found to decrease with increase in pH in all the compounds studied. The reason for slight decrease of diffusion coefficient with increase in pH may be attributed to the decrease in the less availability of protons. The diffusion coefficient values obtained with different techniques are found to be in good agreement indicating the electrode process to be free from adsorption complications.

The heterogeneous forward rate constant values obtained for all the compounds studied are found to be decreased with increase in pH of the supporting electrolytes due to the shift of reduction potentials to more negative values. This trend shows that the electrode process tend to become more and more irreversible with increase in pH of the solution. The rate constant values to be high in acidic medium indicating that the rate of the reaction in acidic medium in high due to easier avialiability of protons.

Differential pulse polarography has been employed for quantitative estimation of 2,5-dihydroxy and 2,6-dihydroxy substituted chalcones, in addition to the electrode kinetics by employing calibration and standard addition methods. It is shown in this thesis that the well defined diffusion controlled waves obtained with success for working out electro analytical procedures for their quantitative estimations going down to 10-7 to10-8 M.

In conclusion the purpose of using the electro analytical techniques such as D.C. polarography and differential pulse polarography employed for the reduction of a,b-unsaturated ketone are very simple, much more convenient with stereo specificity and selectivity of synthesized organic molecules at ppm level. My present studies are may find several applications in biological active molecule of ketoacidoximes, ketoximes phenylhydrozones etc. Further, I am interested to study electro analytical techniques can be said that present investigation has helped in

b)Identification of reactive intermediates has successfully made.

c)Providing information on the substituent effects has been verified.

A sensitive differential pulse adsorptive stripping voltammetric method for the determination of fluxofenim with universal buffer solution was described. The method was based on the adsorptive accumulation of fluxofenim at hanging mercury drop electrode (HMDE). The cyclic voltammograms demonstrate the adsorption of this compound at the mercury electrode. A systematic study of various operational parameters that effect the stripping response was carried out by DP-AdSV with accumulation potential of -0.80V and 60 sec accumulation time. The calibration plot was linear from 1.0x 10-8 to1.0x 10-5 M. The lower detection limit found to be 0.92x10-7M. Finally the method was applied for the determination of fluxofenim in spiked grains and water samples. The relative standard deviation ad correlation coefficient for fluxofenim was 0.97% and 0.998% respectively.

A differential pulse anodic stripping voltammetric method was based on the accumulation of Mo(VI) complex with phenylpiperazine dithiocarbamate on a hanging mercury drop electrode, followed by measurement of the current of the adsorbed complex. The effects of various parameters, such as reagent concentration, effect of pH of the medium, the accumulation potential, the accumulation time and the scan rate were investigated. Under the optimum conditions, a linear calibration graph was obtained in the concentration range of 0.01 to100 μg/mL with a correlation coefficient of 0.9994 and detection limit of 0.009 μg/mL. The effects of interference ions have been studied and it was found that the method is free from interferences of some common cations. The proposed method was applied for the determination of Mo(VI) in natural water and various food samples and the results showed good agreement with reported methods and the recoveries were in the range of 99.92 to 99.99 and 99.20 to 102.0 % respectively. The relative standard deviation for eight successive replicate analyses of Mo(VI) were 2.3% and 1.2%.

A differential pulse polarographic method has been developed for the determination of Mn(II) and Zn(II) in biological and human hair samples using newly synthesized reagent 2,2'-{benzene-1,2-diylbis(nitrilomethylylidene]}diphenol after preconcentration and separation using amberlite XAD-1180 in the range of pH 8.0-10.0. The sorbed elements was subsequently eluted with 10mL of 2.0 M HCl elutes was analysed by differential pulse polarography (DPP). The interference of foreign ions has also been studied. Effects of various instrumental parameters are investigated and received conditions are optimized. The limits of detections were found to be 0.0026 and 0.0032 μg mL-1 for Mn(II) and Zn(II) respectively by applying a preconcentration factor ~30. The proposed enrichment method was applied successfully for the determination of Mn(II) and Zn(II) in biological and human hair samples. The proposed method was compared with reported methods in terms of Student’s ‘t’-test and Variance ratio ‘f’-test which indicates that there is no significant difference between proposed and literature method at 95 % confidence level.

The electrochemical reduction behavior and determination of sorafenib was studied by differential pulse polarography at dropping mercury electrode. A linear response was obtained over the concentration range 5.0x10-8 to 1.0x10-5M with lower detection limits 4.2x10-8M for sorafenib. Sorafenib exbits well defined cathodic waves in universal buffers over the pH range 2.0 to 6.0. The carbonyl group getting reduced to the saturated compound in a four electron processes and reduction mechanism has been proposed. The kinetic parameters such as diffusion coefficients (D), transfer coefficients (αna) and heterogeneous forward rate constants (K0fh) are evaluated and reported. The relative standard deviation and correlation coefficient value was found to be 0.326% and 0.65 respectively. Differential pulse polarography was employed for determination of the sorafenib in trace levels using both standard addition and calibration methods.
