AZ 628 Usage And Synthesis

Uses

AZ 628 is an inhibitor of B-RAF and B-RAF(V600E)

Definition

ChEBI: 3-(2-cyanopropan-2-yl)-N-[4-methyl-3-[(3-methyl-4-oxo-6-quinazolinyl)amino]phenyl]benzamide is a member of benzamides.

Biological Activity

az628 is a potent and newly discorvered inhibitor of braf, c-raf-1 and brafv600e with ic50 values of 105 nm, 29 nm and 34 nm, respectively. this compound prevents craf activation through persistently occupying the atp-binding site of raf kinase. specificity profile suggests that az628 also inhibits activation of other tyrosine protein kinases such as ddr2, vegfr2, lyn, flt1, fms and others.raf kinases a family of three serine/threonine-specific protein kinases and participate in the ras-raf-mek-erk signal transduction cascade, also known as the mitogen-activated protein kinase (mapk) cascade. the activation of mapk signaling leads to different cellular response such as cell proliferation, apoptosis and inflammation.az628 has the potent anti-tumor activity. in human colon and melanoma-derived cell line that carries the recurrent v600e activating braf mutation, az628 was shown to inhibit anchorage-dependent and -independent growth, induce cell cycle arrest, and cause apoptosis [1]. az628 may be antiangiogenic due to inhibition of vegfr2 [2].generation of melanoma cell line clones is obtained resistance to the raf kinase inhibitor az628. resistance to az628 is connected with raised levels of the raf downstream effector p-erk1/2. erk1/2 initiation in az628-resistant clones is interceded by mek. supported multiplication of az628-resistant clones is to a great extent autonomous of braf kinase action. az628-resistant clones express elevated craf. survival of az628-safe cells is subject to craf [1].

in vitro

AZ628 inhibits B-Raf, B-Raf AZ628 acts on B-Raf-containing M14 parental cell lines treated with increasing concentrations of AZ628, an effective inhibition of p-ERK1/2 levels was observed. It acts on AZ628-resistant M14 cells and does not inhibit ERK activation. AZ628 acts on NRAS-mutated malignant melanoma cells and effectively reduces ERK activation.
