(S)-Crizotinib
目录号 : GC13136An MTH1 inhibitor
Cas No.:1374356-45-2
Sample solution is provided at 25 µL, 10mM.
(S)-crizotinibthe selectively inhibited MTH1 catalytic activity with IC50 of 72 nM, while clinically used (R)-enantiomer of the drug was inactive with IC50 of 1375 nM. Furthermore, direct-binding assays (ITC) indicated a 16-fold higher affinity of the (S)-enantiomer towards MTH1 compared with (R)-enantiomer. By using Km concentrations of substrates, the average IC50 values for (S)-crizotinib and the MTH1 substrates 8-oxo-dGTP and 2-OH-dATP were 330 nM and 408 nM respectively. (S)-crizotinib efficiently inhibited colony formation of SW480 cells andKRAS-mutated PANC1 cells, similar to SCH51344. In addition, in vitro Kd measurements indicated that (S)-crizotinib was considerably less potent than the (R)-enantiomer against the established targets ALK,MET and ROS1. (S)-crizotinib did not lead to the detection of any significant effects on proliferation in SW480 cells and showed highest toxicity towards the SV40T and KRASV12 cells. (S)-crizotinib, in contrast to (R)-crizotinib, efficiently stabilized MTH1 validating the differential targeting within BJ-KRASV12 cells using a cellular thermal shift assay. (S)-crizotinib induced an increase in DNA single-strand breaks, activated DNA repair in human colon carcinoma cells, and effectively suppressed tumour growth in animal models as a result of disruption of nucleotide pool homeostasis via MTH1 inhibition.
In vivo mouse xenograft studies showed (S)-crizotinib, but not the (R)-enantiomer, was able to impair overall tumour progression aswell as specifically reduce tumour volume by more than 50%.

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
