IAG933
IAG933 is Novartis’ potential first-in-class small molecule inhibitor of the PPI between YAP/TAZ and TEAD, currently in a Ph. I trial for solid tumors with Hippo pathway alterations. This case study not only highlights a fascinating mechanism of action but also serves as an excellent example of how to leverage structural data to inform hit selection and guide lead optimization, how to employ multiparameter optimization to circumvent cardiotoxicity liabilities, and how to redirect metabolism.
HRO761
Novartis’ HRO761 is an oral allosteric WRN helicase inhibitor, aimed at treating MSI-high and dMMR tumors. This article details the discovery of HRO761 and highlights the importance of selecting appropriate assays during early HTS as well as transferable medicinal chemistry strategies to optimize permeability and solubility through the modulation of LipE, neutral TPSA, chameleonicity, and non-classical zwitterions. It also explores the X-ray structure of HRO761 bound to WRN, how it differentiates from Vividion's VVD-214, its preclinical activity, clinical status, chemical synthesis, and more!
sonrotoclax (BGB-11417)
Sonrotoclax, BeiGene’s clinical-stage, orally bioavailable, next-generation inhibitor, targets both WT and mutated forms of the Bcl-2 protein by binding within a hydrophobic groove, similar to other inhibitors in its class. Explore this case study to see how sonrotoclax was rationally designed to potency against both WT and mutant Bcl-2 and address the limitations of first-generation inhibitors and more!
AZD4144
Recently, a surge of (pre)clinical compounds inhibiting the NLRP3 inflammasome, often featuring a hexahydroindacene ring system, has emerged, including Nodthera’s ND-0796. In a push for new chemotypes, AZ and Mitsubishi Tanabe have disclosed their clinical compound, AZD4144, which is currently in Ph. I trials in healthy volunteers. The discovery story detailed their efforts to overcome PLD (phospholipidosis), genotoxicity, and hERG inhibition in a non-classical pharmacophore series. The discovery was presented by Anders Johansson at the EFMC-ISMC 2024 Meeting in Rome.
acoramidis (Attruby)
BridgeBio’s acoramidis (Attruby), an oral, second-generation stabilizer of the TTR protein, has been approved by the FDA for the treatment of ATTR-CM (transthyretin amyloid cardiomyopathy). Amyloid deposits in the heart muscle characterize the rare but potentially fatal disease. This case study reviews the history of TTR modulation, early experiments validating the therapeutic potential of TTR stabilization, the binding mechanism of acoramidis to TTR, the importance of binding enthalpy for differentiation, and the molecule’s impressive 30-month clinical data following an early scare.
