hras 1

Hras-1Y i-motif Probe-1 is a probe of the hras-1Y i-motif which selectively and directly interacts with it.

AMG410 is a non-covalent, dual-modality KRAS inhibitor effective against both GDP (OFF) and GTP (ON) binding, with Kd (GDP) of 1 nM and Kd (GTP) of 22 nM, capable of blocking KRAS independently of the cell cycle. AMG410 does not affect HRAS and NRAS2, and exhibits high potency against KRAS G12D, G12V, G12C, G13D, and other mutants, with an IC₅₀ of 1–4 nM. It induces tumour regression and reduces phosphorylated ERK levels in KRAS-mutant cancer models.

RAS inhibitor Abd-7 is a powerful compound (Kd=51 nM) that binds to RAS and inhibits the protein-protein interaction (PPI) between RAS and its effectors. By interacting with RAS within cells, RAS inhibitor Abd-7 hinders RAS-effector interactions and suppresses endogenous RAS-dependent signaling. Additionally, RAS inhibitor Abd-7 disrupts the PPI of different mutant KRAS proteins with PI3K, CRAF, RALGDS, as well as NRAS Q61H and HRAS G12V[1].
