Uses
Used in Cancer Treatment:
Tozasertib is used as a multikinase inhibitor for cancer treatment. It effectively inhibits the proliferation of various cancer cell lines, particularly clear cell renal carcinoma, with IC50s of less than 10 μM. In a rodent model of cancer, Tozasertib blocks tumor growth at a dosage of 80 mg/kg, inhibiting histone H3 phosphorylation and increasing apoptosis. By depleting Aurora kinase activity, it disrupts bipolar spindle formation during mitosis, leading to cell cycle arrest at the G2/M phase.
Biochem/physiol Actions
VX-680 is an ATP site-targeting potent aurora kinase inhibitor (Aurara A/B/C Ki(app) = 0.6/18/4.6 nM) that affects FLT3, BCR-Abl, BCR-Abl (T315I), Lck, ITK, Src, and Fyn only at higher concentrations (Ki(app) = 30, 30, 42, 80, 220, 350, 520 nM, respectively) and exhibits little inhibitory potency toward 52 other kinases (Ki(app) >1 μM). VX-680 exhibits potent antiproliferation activity in a wide variety of cancer cultures (IC50 from 15 to 113 nM) as a result of cell cycle arrest and apoptosis induction, as well as causes tumor retardation (by 98% on day 13; 75 mg/kg b.i.d i.p.; HL-60 in mice) and regression (2 mg/kg/h 3 d/wk i.v. infusion; HCT116 in rats) in vivo. Crystallography data reveal a tight association of VX-680 with a hydrophobic pocket present only in a closed, inactive kinase conformation, which forms the basis of its selectivity profile, including its activity toward wild-type and the Imatinib-resistant (T315I) Abl.

Check Digit Verification of cas no
The CAS Registry Mumber 639089-54-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,9,0,8 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 639089-54:
(8*6)+(7*3)+(6*9)+(5*0)+(4*8)+(3*9)+(2*5)+(1*4)=196
196 % 10 = 6
So 639089-54-6 is a valid CAS Registry Number.
