In another study, a series of chromene-1,2,3-triazole derivatives were synthesized, and the cytotoxicity activity of newly synthesized hybrids was tested against three human cancer cell lines, including MCF-7, MDA-MB 231, and HCT, as well as the in vitro inhibitory potential of all derivatives against CDK9/cyclin T1 was assessed. Here, CCNT1 is linked to cancer.
