(S)-crizotinib

(S)-crizotinib disrupts nucleotide pool homeostasis via MTH1 inhibition, induced an increase in DNA single-strand breaks, activated DNA repair in human colon carcinoma cells, and effectively suppressed tumour growth in animal models. Over all, (S)-crizotinib is an attractive chemical entity for further pre-clinical evaluation, and small-molecule inhibitors of MTH1 in general as a promising novel class of anticancer agents.
