Synthesis and Primary Antitumor Screening of 5-Ylidene
Derivatives of 3-(Morpholin-4-yl)-2-sulfanylidene-1,3-thiazolidin-4-one
摘要:
A preparative procedure has been developed for the synthesis of 3-(morpholin-4-yl)-2-sulfanylidene-1,3-thiazolidin-4-one (3-morpholinorhodanine). Its reaction with aldehydes afforded a number of previously unknown 5-ylidene derivatives which were screened for antitumor activity. The synthesized compounds showed a moderate activity against most malignant tumor cells. The renal cancer cell lines UO31 and TK10 were found to be most sensitive to all the tested compounds.
Design and synthesis of substituted morpholin/piperidin-1-yl-carbamodithioates as promising vaginal microbicides with spermicidal potential
摘要:
A series of seventeen morpholin/piperidin-1-yl-carbamodithioate (3-19) were synthesized as topical vaginal microbicidal spermicides. The synthesized compounds were evaluated for their anti-Trichomonas activity against MTZ susceptible and resistant strains along with their spermicidal and antifungal potential. All the synthesized compounds were assessed for their safety through cytotoxic assay against human cervical cell line (HeLa) and compatibility with vaginal flora, Lactobacillus. The study identified eleven dually active compounds with apparent safety. The plausible mode of action of these compounds was through sulfhydryl binding, confirmed via reduction in available free thiols on human sperm. The most promising compound 9 significantly inhibited (P < 0.001) thiol-sensitive sperm hexokinase. The stability of compound 9 in simulated vaginal fluid (SVF) was performed via HPLC-PDA method, which supported its utility for vaginal administration. (C) 2014 Elsevier Ltd. All rights reserved.
