The Takeda cholesterol 24-hydroxylase inhibitor, soticlestat (TAK-935, previously OV935) is a potent, highly selective, first-in-class inhibitor of the brain-specific enzyme cholesterol 24-hydroxylase (CH24H). Cholesterol 24-hydroxylase converts cholesterol to 24S-hydroxycholesterol, which acts as a positive allosteric modulator of [...]

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.

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 Pfizer CFTR potentiator, CP-628006 , enhances CFTR function in cystic fibrosis patient-derived airwell cells with a distinct mechanism of action from existing potentiators such as ivacaftor. It has a unique chemical structure, and in contrast to other potentiators does not seem to inhibit the channel at high concentrations of drug and [...]

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 [...]
