SUMMARY

A senior organic and medicinal chemist with extensive experience in

different areas:

. Synthesis of biologically active compounds in various stages of drug

discovery research from hit identification and expansion, hit to lead

& lead optimization, till supporting IND enabling studies.

. Synthesis of compounds for drug discovery research with break through

in compound in vivo activity, selectivity, pharmacokinetics, and

toxicity profiles.

. Comparative patent analysis, circumventing IP coverage, and

establishing patentable chemistry areas.

. Structure-based and computation-aided drug design.

. Combinatorial synthesis of compound libraries for biologically active

"hit compound" identification.

. Compounds scale-up (grams, hundreds of grams) for advanced animal

efficacy and toxicity study.

. Synthesis and scale-up of photo sensors as initiators for photo-

induced polymerization (kilograms).

. Total synthesis of natural products.

. Novel synthesis of unnatural amino acids and peptides.

. Developing synthetic methodology for the preparation of heterocycles.

. Authoring and co-authoring scientific publications.

. Supervising research associates & working as lead chemist/project

coordinator.

KEY ACHIEVEMENTS

. Contributed to the discovery of clinical candidates for the treatment of

osteoporosis and frailty through conceptualizing and synthesizing novel

compounds for first generation non-steroidal tissue selective androgen

receptor modulators (SARMs) program.

. Independently developed a series of second-generation SARM compounds,

four of which have passed advanced animal studies, demonstrating greatly

improved tissue selectivity over clinical candidate LGD2941. Two were

selected by collaborator TAP and were ready to be developed into IND

track.

. Invented new SARM scaffold which demonstrated ideal 3rd generation

profile in primary assays, indicating the possibility of reaching potent

therapeutic compounds free of major side effects that challenge all SARM

researchers.

. Designed and synthesized novel series of small molecules that mimic the

activity of thrombopoietin (TPO), a protein factor that promotes growth

and production of blood platelets. These compounds defined new patent

areas in TPO research field, improved potency and efficacy over clinical

candidate LGD4665, and were considered as backup compounds for LGD4665 at

that stage of research.

. Discovered novel lead compounds for two kinase projects for the treatment

of osteoarthritis (targets confidential) through extensive patent study

and new core structure development aided by a rich source of structural

biology information, CADD evaluation, and compounds library synthesis.

. Discovered a novel structure series, which improved compounds potency and

metabolic stability for clinical candidate development in a new class

antibiotics discovery project for the broad-spectrum treatment of gram-

positive bacteria infection, including infections caused by clinically

relevant resistant strains.

. Achieved world first total synthesis of natural product Jatrophatrione,

teaming with a fellow student.

. Developed synthetic methodology for the preparation of unnatural amino

acids and heterocyclic structures.

PROFESSIONAL EXPERIENCE

strategies for IP establishment and lead optimization, goal, timeline,

cost, business model, etc)

research activities, redirection of research, and selection of compounds

for advanced profiling.

. Designed novel SAR targets and optimized lead compounds using the

knowledge obtained from ligand-protein co-crystal structures in

collaboration with a computational chemist (structural-based design).

. Supported compound animal efficacy and toxicity study, IND enabling

studies by exploring new synthetic routes and optimizing reactions for

scale-up synthesis (up to 100+ grams).
