Abstract

p53-independent malignant Cancer is still severe health problem of human beings. HIF-1 pathway is believed to play an important role in the survival and developing progress of such cancers. In the present study, with the aim to inhibit the proliferation of p53-independent malignant cells, we disclose the optimization of 6a, the starting compound which is discovered in the screening of in-house compound collection. The structure-activity relationship (SAR) is summarized. The most potent derivative 8d, inhibits the proliferation of both p53-null and p53-mutated cells through inhibition of HIF-1 pathway. Our findings here provide a new chemotype in designing potent Anticancer agent especially against those p53-independent malignant tumors.
