Previously, we demonstrated that 5,5-diphenyl-2-thiohydantoin (DPTH) exerts an anti-proliferation effect on subcultured human umbilical vein endothelial cells (HUVEC). In the present study, we show that 2(naphthalen-2-ylmethylsulfanyl)-5,5-diphenyl-1,5-dihydro-imidazol-4-one (DPTH-N10), a derivative compound of DPTH, exerts a 5 times stronger inhibition of [3H]thymidine

A series of 5,5-dimethylthiohydantoin derivatives were synthesized and evaluated for androgen receptor pure antagonistic activities for the treatment of castration-resistant prostate cancer. Since CH4933468, which we reported previously, had a problem with agonist metabolites, novel thiohydantoin derivatives were identified by

To obtain a rapid, efficient and mild synthesis of 5,5-diphenylhydantoin and 5,5-diphenyl-2-thiohydantoin derivatives, ultrasonic irradiation has been applied to the reaction mixtures containing substituted benzils and urea or thiourea derivatives catalyzed by KOH in DMSO/H(2)O, which allowed us to achieve

Previously, we identified DPTH, an analogue of antiepileptic drug phenytoin (5,5-diphenylhydantoin, DPT), capable of retarding the cell cycle in the human vascular endothelial cells. Our data suggest that DPTH inhibits human umbilical venous endothelial cells (HUVEC) proliferation by increasing the

Some years ago, we reported that colloid goiters could be produced experimentally in mice and rats by injection of TSH over a few days in the presence of ample iodine supply. This clearly showed that colloid accumulation and intense TSH
