2-(Thienothiazolylimino)-1,3-thiazolidin-4-ones inhibit cell division cycle 25 A phosphatase
摘要:
Cell division cycle dual phosphatases (CDC25) are essential enzymes that regulate cell progression in cell cycle. Three isoforms exist as CDC25A, B and C. Over-expression of each CDC25 enzyme is found in cancers of diverse origins. Thiazolidinone derivatives have been reported to display anti-proliferative activities, bactericidal activities and to reduce inflammation process. New 2-(thienothiazolylimino)-1,3-thiazolidin-4-ones were synthesized and evaluated as inhibitors of CDC25 phosphatase. Among the molecules tested, compound 6 inhibited CDC25A with an IC50 estimated at 6.2 +/- 1.0 mu M. The binding of thiazolidinone derivative 6 onto CDC25A protein was reversible. In cellulo, compound 6 treatment led to MCF7 and MDA-MB-231 cell growth arrest. To our knowledge, it is the first time that such 4-thiazolidinone derivatives are characterized as CDC25 potential inhibitor. (C) 2016 Elsevier Ltd. All rights reserved.
在这项工作中,我们描述了从3-氨基硒吩(使用硫光气)开始的3-isothiocyanatoselenophenes的合成。然后在氢氧化铵存在下将那些化合物转化为相应的硫脲。使用DDQ在2-氨基硒代[3,2- d ]噻唑中环化。使用相同的途径从3-异硫氰酸根合噻吩获得2-氨基噻吩并[3,2- d ]噻唑。

Synthesis of novel 2-aminothieno[3,2-d]thiazoles and selenolo[3,2-d]thiazoles
3-aminoselenophenes (using thiophosgene). Those compounds were then converted to the corresponding thioureas in the presence of ammonium hydroxide. Cyclization in 2-aminoselenolo[3,2-d]thiazoles was achieved using DDQ. 2-Aminothieno[3,2-d]thiazoles were obtained from 3-isothiocyanatothiophenes using the same pathway.
