Dr. Fausto Carnevale Neto

Dr. Fausto is a senior scientist at Hexagon Bio, Natural Product Chemistry, focused on combining large-scale metabolomics measurements and orthogonal compound identification tools to accelerate the discovery of new therapeutically-relevant secondary metabolites encoded in the global metagenome of fungi. Previously, he was an Assistant Professor at the University of Washington School of Medicine (2018-2023) and a research scientist at the Northwest Metabolomics Research Center (NWMRC), developing tandem MS-based metabolomics workflows combined with network analysis for insights into phenotypic changes, molecular assignment, and biomarker discovery.

Discovering novel clinically relevant molecular species encoded in fungal genomes using tandem MS-based metabolomics

Fungal secondary metabolites represent a valuable resource for drug discovery pipelines. Numerous front-line therapeutics arise from unique cytostatic, immunosuppressant, lipid-lowering, and antimicrobial compounds encoded in untapped biosynthetic gene clusters (BGCs) and hidden in complex fungal metabolomes. Advances in high-throughput screening, computational genome mining, and synthetic biology have allowed to effectively dissect biosynthetic pathways whose products are likely to have desired bioactivities, identify resistance genes associated with potential targets, and engineer chosen gene clusters into a heterologous host for large-scale metabolite production. Yet, accurately assessing small bioactive molecules from complex fungal extracts remains challenging. Due to the need for high-throughput methods for discovering new molecules, we have redesigned untargeted workflows that combine large-scale metabolomics measurements using liquid chromatography-tandem mass spectrometry (LC-MS2) with computational solutions for data analysis and bioassays. Our approach incorporates mass spectral networks, orthogonal annotation tools built on existing technologies, and gas-phase fragmentation mapping. Utilizing tandem MS-based metabolomics, cell-based assays, and bioinformatics, we aim to speed up biological sample exploration and enable the discovery of novel compounds with novel mechanisms of action.

Come have a lunch with us and meet two ACS editors in another edition of ACS on Campus: Lori Ferrins – Topic Editor, Journal of Medicinal Chemistry; and Carolina Horta – Associate Editor, ACS Omega. The event will be part of 11th BrazMedChem and 9th BCNP programs. We will discuss valuable tips on how to prepare your manuscript in an efffective way as well as what our editors expect about an impactful paper. In addition, we will talk about Open Access and its impact on the visibility and democratization of scientific knowledge. The ACS on Campus will be held on Oct 25 at 12 PM (local time). All attendees will recieve a lunch box and a certificate. Register here: cvent.me/4K1qLP #ACSonCampus
