Abstract

Several derivatives of hydantoin containing glutarimide or succinimide at the 3-position were synthesized. The new hydantoin derivatives had a structure similar to that of thalidomide, and so may possess activity similar to that of thalidomide and/or its analogs, such as effects on cell differentiation and angiogenesis. Some hydantoins showed enhancing effects on all-trans retinoic acid (ATRA)-induced cell differentiation of human leukemia cell line HL-60 and anti-angiogenic activity on human umbilical vein endothelial cells (HUVEC). These new hydantoin derivatives were more effective than thalidomide in cell differentiation-inducing activity on HL-60 and anti-angiogenic activity on HUVEC.
