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.

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.

The Galapagos CFTR potentiator, GLPG2451, is an oral, once-daily clinical candidate for cystic fibrosis (5-80 mg QD). It was advanced into a high-profile Ph. II triple-combo study with the CFTR correctors GLPG2737 and GLPG2222 in partnership with AbbVie, and was seen as a potential competitor to Vertex’s CF franchise, but unfortunately weak [...]

Zilucoplan is a macrocyclic peptide-containing drug with 15 amino acids in total, targeting the challenging-to-drug C5 complement protein and formulated for self-administered once-daily SC injection. In Sept. 2023, zilucoplan received its first global approval in Japan, followed in Oct. 2023 by FDA approval for gMG patients who are AChR antibody-positive, making zilucoplan the first drug derived from mRNA display for cyclic peptides to be approved. This case study discusses how zilucoplan was discovered and why it’s an important scientific milestone for the industry.

The Mirum Pharmaceuticals IBAT bile acid transporter inhibitor, maralixibat , has a long history, having been first patented by scientists at Searle in 1994 and published by the time Searle became part of Pharmacia in 2005 . It was finally approved in Sep. 2021 for treatment of cholestatic pruritis in patients with Alagille Syndrome, and is [...]
