Discovery of 1,2,4-thiadiazolidine-3,5-dione analogs that exhibit unusual and selective rapid cell death kinetics against acute myelogenous leukemia cells in culture
چکیده انگلیسی

4-Benzyl-2-methyl-1,2,4-thiadiazolidine-3,5-dione (TDZD-8) was previously identified as an antileukemic agent exhibiting no evident toxicity toward normal hematopoietic cells. An SAR study has been carried out to examine the effect of varying the C-2 and C-4- substituents on the thiadiazolidinone ring of TDZD-8 on antileukemic activity. These studies resulted in the identification of more druglike analogs that exhibited comparable potency to TDZD-8 in killing acute myelogenous leukemia (AML) cells in culture. Surprisingly, the cell death kinetics induced by several of these novel analogs on MV-411 cells were extremely fast, with commitment to death occurring within 30 min. At a concentration of 10 μM, 3f (LD50 = 3.5 μM) completely eradicated cell viability of MV-411 cells within 2 h, while analog 3e (LD50 = 2.0 μM) decimated cell viability within 30 min at a concentration of 10 μM and effectively abolished cell viability at 5 μM within 1–2 h.
