Discovery of New Immunomodulatory Anticancer Thalidomide Analogs: Design, Synthesis, Biological Evaluation and In Silico Studies.

New thalidomide analogs have been designed and synthesized by hybridizing the immunomodulatory gutarimide moiety with three antiproliferative nuclei: quinazolinedione, phthalazinedione, and quinoxalinone. The biological results revealed the strong impact of quinazoline derivatives 7 a and 28, and phthalazine based 20 a against HepG-2, MCF-7, PC3, and HCT-116 cell lines, compared to thalidomide. In particular, compound 20 a was the most promising as it had far better biological activity than thalidomide with regard to inhibition of TNF-α, IL-6, caspase 3, COX-I/II, and VEGFR-2, as well as cell cycle arrest, and apoptosis rate enhancement in MCF-7 cells, the most sensitive cell line to the current new molecules.
