Drug Discovery using Natural Products – Optimization Studies of Inhibitors of Glucan Synthesis as Anti-Fungal Agents

Speakers for this Event:
  • Mike Peel, Ph.D., Executive Director Discovery Research, SCYNEXIS, Inc. 
  • James Balkovec, Ph.D., Principal and Owner, ChemTract LLC
  • Inhibition of b-1,3-glucan synthesis is the mechanism of action of the echinocandin class of natural products and has been shown to result in clinically effective therapy for important fungal pathogens including azole resistant Candida spp. and invasive Aspergillus spp. Infection.

    This presentation will outline the chemical modifications of the lipopeptide pneumocandin which led to the discovery and clinical introduction of Cancidas® as an important advance in anti-fungal therapy. A new class of b-1,3-glucan synthesis inhibitor, the triterpene enfumafungin, was recently disclosed which displays broad spectrum (Candida and Aspergillus spp.) antifungal (AF) activity. Importantly, derivatives of enfumafungin were discovered that show good oral bioavailability and have robust anti-fungal activity in mouse models of disseminated disease when delivered orally.

    The talk will outline the steps taken to transform a complex natural product with poor ‘druggability’ features into an orally available agent suitable for clinical investigations.

    THIS PROGRAM IS INTENDED FOR

    The presentation will be of interest to medicinal chemists, particularly those working on performing studies on natural products or large molecular weight compounds with features not typically associated with good drug-like properties.

    The information will also be useful for scientists with an interest in anti-fungal drug discovery.
