In 2022, Amgen acquired ChemoCentryx for $4B in cash, primarily for avacopan, a first-in-class treatment approved in 2021 for a rare automimmune condition, anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Scientifically, it is notable that avacopan is the first small molecule targeting the complement pathway to be [...]

Last year, Biogen announced that it would acquire Texas biotech Reata Pharmaceuticals for $7.3B. Reata’s lead molecule, omaveloxolone (SKYCLARYS®), an oral, reversible covalent inhibitor of the E3 ligase KEAP1, became the first drug approved for Friedrich’s Ataxia. Omaveloxolone was previously highlighted as a Molecule of the Month in July 2023. Now, this 2023 Molecule of the Year nominee reflects a historic milestone for neurological drug discovery. This comprehensive explainer dives into Nrf2 target rationale, how it works, how the drug was discovered, its synthesis, and why it’s a big deal.

JNT-517 is Jnana Therapeutics' first-in-class cryptic allosteric SLC6A19 inhibitor to treat phenylketonuria (PKU). This is a notable case study employing a novel lead generation approach with photoaffinity probes, leading to a clinical candidate for a historically challenging-to-drug target class. Read the case study to learn how Jnana used their RAPID technology to quickly generate allosteric inhibitor hits, the SAR that led to the discovery of JNT-517, and why the molecule is notable.

“compound 18” is an oral inducer of fetal hemoglobin (HbF) intended to treat anemias such as sickle cell disease and beta-thalassemia. The authors identified a weak hit (>10 uM) from a high-throughput phenotypic screen using human umbilical cord blood-derived erythroid progenitor cells. Optimization led to the azaspiro[3.3]heptane-containing [...]

Inaxaplin (VX-147), developed by Vertex, is an inhibitor of APOL1 channel activity currently in a Ph. II/III pivotal study for the treatment of chronic kidney disease caused by specific variants of the APOL1 gene. It was recently granted Breakthrough Therapy designation by the FDA and PRIME designation by the EMA. The discovery story, which is an excellent case study for the use of MetID. Inaxaplin has been called “the most important genomic-driven drug discovery for chronic kidney disease this century”, acting on a target with a fascinating human genetic validation story.
