MRTX1133 Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden
MRTX1133 is a potent and selective KRAS G12D inhibitor that targets KRAS G12D protein in both the active and inactive states. In preclinical studies, MRTX1133 exhibited a long half-life, was able to bind to KRAS G12D protein in both active and inactive states, and selectively inhibited KRAS G12D-mutated cancer cells. In G12D mutant tumor models, it showed dose-dependent selective inhibition of the KRAS pathway and tumor regression.
Beschreibung
MRTX1133 is a potent KRAS^G12D inhibitor. Treatment by intraperitoneal (IP) administration is effective against tumours in xenograft mice with KRAS^G12D mutations. However, MRTX1133 has low oral bioavailability (only 0.5%), which may be related to gastrointestinal malabsorption. In addition, MRTX1133 has two hydrogen bond donors (HBDs): a phenolic group and a secondary amine moiety. And the secondary amine molecule is considered to be the main cause of malabsorption. Currently, an oral prodrug of MRTX1133 has been developed to effectively treat tumours in xenograft mice with the KRAS^G12D mutation^[1].
Chemische Eigenschaften
Solid powder.
Verwenden
MRTX1133 is primarily used in studies targeting advanced solid tumours with KRASG12D mutations, such as human pancreatic ductal adenocarcinoma (PDAC), non-small cell lung cancer (NSCLC) and colorectal cancer.
Biologische Funktion
MRTX1133 is a noncovalent, potent, and selective KRAS G12D inhibitor. It optimally fills the switch II pocket and extends three substituents to favorably interact with the protein, resulting in an estimated KD against KRAS G12D of 0.2 pM. MRTX1133 prevents SOS1-catalyzed nucleotide exchange and/or formation of the KRAS G12D/GTP/RAF1 complex, thereby inhibiting mutant KRAS-dependent signal transduction. This inhibitor selectively inhibits KRAS G12D mutants but not KRAS wild-type tumor cells. MRTX1133 has single-digit nanomolar activity in cellular assays and marked in vivo efficacy in tumor models harboring KRAS G12D mutations.
