Experience

Undisclosed Company, Director of Chemistry, 2010 - Present

  • Leading entrepreneurial, intellectual property and technology development for programs directed at hepatitis B, liver cancer, or multiple viruses.
  • Directed the technical feasibility, contributed to business plan development, provided input into the contract negotiations, and coordinated logistics for the donation of a large pharmaceutical research laboratory - natural product collection.
  • Developed marketing plan for the Natural Products Discovery Institute, resulting in initial funding from the NIH and interest from multiple Clients.
  • Performing business development activities related to acquiring assets supportive of anti-viral programs.
  • Filed, received, and implemented state innovation grants to support our drug discovery and diagnostic programs.
  • Proposed a new anti-viral project in collaboration with Drexel University to develop PI3K p110 Delta kinase inhibitors that block host cell signally pathways important for viral replication. This project was funded by a Pennsylvania DCED Innovation Grant.

Undisclosed Company, Founder and Director of Chemistry, 2008 - Present

  • Performed synthetic studies that determined the identity of the major human metabolite of JWH-018, a synthetic cannabinoid agonist, and provided reference material for LC method development.
  • Prepared Drug Discovery due diligence reports and research proposals for business development opportunities (CNS, Pain, Oncology, and Metabolic Disease) within major Pharmaceutical Company to facilitate their decisions on the technologies.
  • Directed the outsourcing of medicinal chemistry to Eastern Europe and Asia resulting in diverse libraries of well characterized compounds.
  • Provide medicinal chemistry advice for Biotechnology Companies, Pharmaceutical Companies, and Academic Groups.
  • Involved with SBIR proposal writing, lead design/optimization, literature searching, and mechanism of action investigations, biotechnology company start-up, and freedom to operate evaluations.

Johnson & Johnson, Spring House, PA, Research Fellow, 2000 - 2007

  • Identified drug candidate; an alpha-v beta-3/5 integrin antagonist with oral efficacy in animal models of eye disease.
  • Experimentally determined absolute stereochemistry of a medicinal compound by a combination of x-ray crystallography and synthesis.
  • Implemented and researched collaborative project with J-Star Research to improve process efficiency and throughput for scale-up.
  • Worked with a homogeneous catalysis contractor (Johnson-Matthey) to attain excellent stereocontrol and low catalyst loading.
  • Investigated experimentally a novel organocatalytic method to control two stereocenters simultaneously.
  • Identified a 2-azabicyclo[2.2.2]octane-based alpha-4 beta-1 integrin antagonist as an inhaled anti-asthmatic agent and put together compound monograph for compound development recommendation.
  • Identified the minimum structural requirements for activation of the urotensin-II receptor by its peptide ligand, therefore generating a novel ligand for use in HTS.
  • Developed multiple, novel series of small-molecule U-II receptor antagonists with single-digit nanomolar potency utilizing structure based drug design.
  • Currently preparing a Perspective Article for J. Med. Chem. on the Urotensin-II Field.
  • Wrote a postdoctoral research proposal, recruited a scientist, and participated in a project that identified self-assembling collagen-mimetic peptides with thrombogenic properties.
  • Initiated collaboration with Cresset Biomolecular to quantify-stacking interactions, which led to three scientific papers in high-impact journals and potential practical applications.

Magainin Pharmaceuticals, Plymouth Meeting, PA, 1993 - 1999

  • Inventor on two new molecular entities (NME's) that moved into clinical development: Squalamine and trodusquemine.
  • Developed SAR on the anti-infective properties of squalamine, other natural aminosterols, and analogs.
  • Redirected resources towards the development of a practical 16-step synthesis of squalamine.
  • Experimentally developed a practical method of converting squalamine to trodusquemine and produced material for in vivo characterization.
  • Outsourcing: Selected five external manufacturers and negotiated contracts to define intellectual property ownership, scope of project, deliverables, and specifications on intermediates and final products to meet budgetary and time line criteria.
  • cGMP synthesis: Completed production of GMP squalamine drug substance on time and on budget to initiate Phase I clinical trials in oncology.
  • Regulatory filings: Prepared the Chemistry Manufacturing and Controls section of the IND on squalamine lactate, as part of the IND Project Team.
  • Led project team (chemistry and biology) on the centrally acting anti-obesity agent trodusquemine.
  • Applied for and received a Small Business Innovation Research (SBIR) grant from the National Cancer Institute (NCI) to develop an abbreviated route to squalamine.

Wyeth-Ayerst Laboratories, Princeton, NJ, 1989 - 1993

  • Designed and synthesized a structurally unusual NMDA-antagonist (Perzinfotel; EAA-090) under trial for the treatment of neuropathic pain.
