Synthesis, biological evaluation and molecular docking studies of Combretastatin A-4 phosphoramidates as novel anticancer prodrugs

AbstractA new series of CA4P analogs (5a-g, 6a-g) has been designed and effectively synthesized via a one-pot reaction from Combretastatin A-4/Erianin, commercially available amino acid esters and phenyl dichlorophosphate. To establish new candidates with anticancer activity, the in vitro antiproliferative effect of these compounds was measured by the CCK8 method on different cancer cell lines such as human liver caricinoma (HepG2), cervical cancer (HeLa) and colorectal carcinoma (HCT-116). The structure-activity relationships between CA4P outgrowth-promoting activity and its analogs suggested that the biaryl structure linked with double bond in Part A and the steric effect at the positionα-carbon atom in the amino acid ester moiety (Part B) are essential for affecting the in vitro proliferation inhibitory activity of CA4P analogs. Additionally, the results of biological activity and molecular docking simulation showed that the vast majority of these novel Phosphoramidate derivatives exhibited potent anti-cancer activities.
