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].

Check Digit Verification of cas no
The CAS Registry Mumber 878739-06-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,8,7,3 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 878739-06:
(8*8)+(7*7)+(6*8)+(5*7)+(4*3)+(3*9)+(2*0)+(1*6)=241
241 % 10 = 1
So 878739-06-1 is a valid CAS Registry Number.
