描述

一般說明

A cell-permeable 11-mer cyclic peptide that displays high-affinity towards Ras-GTP (IC₅₀ = 120 nM for K-Ras G12V) and inhibits Ras signaling. Shown to readily localize into cytoplasm and directly bind to Ras-GTP near the effector-binding site in a reversible manner. Dose-dependently impairs Ras-B-Raf interaction and blocks EGF-stimulated activation of Akt, MEK & ERK (IC₅₀ = 3.1 µM in H1299 cells). Efficiently induces lung cancer cell growth arrest and triggers apoptosis (LD₅₀ = 3.0 µM in H1299). NOTE: ala = D-Alanine; nal = D-2-naphthylalanine; nle = D-norleucine; Fpa = L-4-Fluorophenylalanine
