Abstract
A new series of N-substituted diarylidenepiperidin-4-ones was synthesized and screened for their possible anticancer activity at the NCI Developmental Therapeutic Program. Almost all the synthesized compounds showed more potent antiproliferative activity than curcumin. The most active compound in this study was 3,5-bis(4-bromobenzylidene)-1-propanoylpiperidin-4-one (8a) with MGMID GI50, TGI, and LC50 values of 0.35, 1.62 and 9.12 µM, respectively. Compound 8a displayed broad spectrum antiproliferative activity with GI50 values below 1 µM in 81% of the tested cell lines and was found to be two folds more potent than EF-24. A detailed study of the structure activity relationship of the N-substitution was also described.

Induction of cell death in cancer cells by modulating telomerase activity using small molecule drugs
Telomeres are distinctive but short stretches present at the corners of chromosomes and aid in stabilizing chromosomal makeup. Resynthesis of telomeres supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no any telomerase activity in human somatic cells, but the stem cells and germ cells undergone telomerase ...read more
