PI3K signal pathway plays a vital role in cellular functions and becomes an attractive approach for cancer therapy. Herein, a new series of novel chromeno[4,3-c]pyrazol-4(2H)-one derivatives bearing sulfonylpiperazine based on the PI3K inhibitors and our previous research. They were screened for their PI3K inhibitory activities and anticancer effects in vitro. Biological studies indicated that compound 7m revealed the remarkable antiproliferative activity (IC50 ranging from 0.03 to 0.09 mu M) against four cancer cell lines (A549, Huh7, HL60 and HCT-116). Besides, compound 7m displayed a certain selective for PI3K alpha (IC50 = 0.009 mu M) over PI3K beta, gamma and delta, and meanwhile, it can remarkable decreased the expression level of p-Akt (Ser473) and p-S6K. In addition, compound 7m could not only induce HCT-116 cell arrest at G1 phase in a dose-dependent manner, but also induce cell apoptosis via upregulation of Bax and cleaved-caspase 3/9, and downregulation of Bcl-2. Besides, compound 7m can remarkably inhibit the growth of tumor in vivo. The above results suggested that compound 7m could be considered as a promising PI3K alpha inhibitor.
