The article conveys some information:
Through virtual screening, we identified the lead compound MCL1020, which exhibited modest CHK1 inhibitory activity. Then a series of 5-(pyrimidin-2-ylamino)picolinonitrile derivatives as CHK1 inhibitors were discovered by further rational optimization. One promising mol., I, whose potency was one of the best, had an IC50 of 0.4 nM with remarkable selectivity (>4300-fold CHK1 vs. CHK2). Compound I effectively inhibited the growth of malignant hematopathy cell lines especially Z-138 (IC50: 0.013 μM) and displayed low affinity for hERG (IC50 > 40 μM). Moreover, I significantly suppressed the tumor growth in Z-138 cell inoculated xenograft model (20 mg/kg I.V., TGI = 90.29%) as a single agent with body weight unaffected. Taken together, our data demonstrated compound I could be a promising drug candidate for the treatment of hematol. malignancies. The results came from multiple reactions, including the reaction of tert-Butyl 4-hydroxypiperidine-1-carboxylate(cas: 109384-19-2Formula: C10H19NO3)
tert-Butyl 4-hydroxypiperidine-1-carboxylate(cas:109384-19-2) is a 4-hydroxypyridine with a boc protecting group used in the preparation of neurologically active agents and other pharmaceutical compounds.Formula: C10H19NO3
