A facile synthesis of α,α′-(EE)-bis(benzylidene)-cycloalkanones and their antitubercular evaluations
摘要:
An economical and facile synthesis of alpha,alpha'-(EE)-bis(benzylidene)-cycloalkanones was achieved by the reaction of cycloalkanones with different aromatic aldehydes using ethanolic KOH in good yields. Few of the selected compounds were reduced with NaBH4 to the respective alpha,alpha'-(EE)-bis(benzylidene)-cycloalkanols. All these compounds and our earlier synthesized cyclohexyl phenyl methanols were evaluated for their antitubercular, antifungal and antibacterial activities. Several compounds displayed moderate antitubercular activity with MIC = 12.5-1.56 mu g/mL. However, none of the compounds displayed any significant antifungal activity. (c) 2008 Elsevier Masson SAS.

Synthesis and Cytotoxic Evaluation of Some 6-Arylidene-2-(α-hydroxyamino-α-arylmethyl)cyclohexanone Oximes and Related Compounds
hydroxylamine hydrochloride and sodium acetate. Ten analogues of 5a, namely 5b-5k, were prepared and evaluated for cytotoxicity. Six of the 11 compounds in series 5, as well as 1, showed activity in the 240-950 microM range against murine mammary EMT6 cells. Series 5 was also examined for cytotoxicity in an in vitro screen conducted by the National Cancer Institute with approximately 54 cell lines, and
