    Product Description

    Daraxonrasib is a non-covalent inhibitor of GTP-bound RAS.1 It binds to peptidyl-prolyl cis-trans isomerase A (PPIase A), also known as cyclophilin A (CypA; Kd = 55.3 nM) to form a binary complex that then binds to wild-type K-Ras, K-Ras(G12V), and K-Ras(G12D) (Kds = 131, 364, and 154 nM, respectively). Daraxonrasib forms a trimeric complex with PPIase A and a K-Ras, H-Ras, N-Ras, or mutant Ras variant and disrupts the protein-protein interaction between these Ras variants and the B-RAF Ras-binding domain (IC50s = 28-220 nM). It induces apoptosis in 28 K-Ras(G12X) and five N-Ras(Q61X) mutant cancer cell lines when used at concentrations ranging from 1 to 100 nM. In vivo, Daraxonrasib (25 mg/kg) inhibits intratumoral ERK phosphorylation and reduces tumor volume in Capan-2 and NCI H441 pancreatic ductal adenocarcinoma (PDAC) mouse xenograft models. It also reduces tumor growth in 29 non-small cell lung cancer (NSCLC), 22 PDAC, and 23 colorectal cancer K-Ras(G12X) mutant mouse xenograft models when administered at a dose of 25 mg/kg.
