Evaluation of some N-acyl analogues of 3,5-bis(arylidene)-4-piperidones for cytotoxic activity.
The synthesis of fourteen N-acyl derivatives of two 3,5-bis(arylidene)-4-piperidones was accomplished and these compounds were evaluated against L1210 leukemia cells in vitro. With one exception, the compounds had IC50 values of less than 10 microM and six of them had IC50 figures in the 0.2-0.6 microM range which were comparable to a reference drug melphalan. Twelve of the sixteen compounds showed specificity for human leukemia cell lines in the NCI in vitro screen. Studies using 1H NMR spectroscopy revealed that solutions of three N-acetylated compounds underwent deamination and possibly other reactions, the deaminated product itself being unstable in the solvent used.
