MCB-294 is a dual-state pan-KRAS inhibitor that selectively inhibits KRAS over NRAS and HRAS. MCB-294 capable of binding both the active (GTP-bound) and inactive (GDP-bound) forms of KRAS with Kds of approximately 1 pM and 10 nM, respectively. MCB-294 broadly impairs the growth of hTERT-HPNE cells expressing G12D, G12C, G12V, G12S, G13D, and wild-type KRAS, with IC50s of approximately 700 nM. MCB-294 induces irreversible apoptosis in KRAS-mutated tumors. MCB-294 effectively suppress KRASG12C inhibitor-resistant cancer cells and remodel the tumor immune microenvironment. MCB-294 can be used for the study of pancreatic cancer, colorectal cancer and lung cancer.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day.
