Abstract
A series of diflunisal 4-thiazolidinones were synthesized. Some selected compounds were determined at one dose towards the full panel of 60 human cancer cell lines by National Cancer Institute. 2',4'-Difluoro-4-hydroxy-N-[4-oxo-2-(thiophen-2-yl)-1,3-thiazolidin-3-yl]biphenyl- 3-carboxamide (4a) demonstrated the most marked effect on K-562 cancer cell line with 58.59 % growth inhibition at 10 μM. Compound 4a was evaluated in vitro using the MTT colorimetric method against human leukemia cell line K-562 and mouse embryonic fibroblasts cell line NIH- 3T3 at different doses for cell viability and growth inhibition. Compound 4a exhibited anticancer activity with IC50 value of 5.2 μM against K-562 cells and did not display cytotoxicity towards NIH-3T3 cells compared with diflunisal. In addition, this compound could be an interesting prototype as an antiproliferative agent.
Keywords: Annexin-V, apoptosis, diflunisal, K-562 cancer cell line, 4-Thiazolidinone.

Discovery of Lead compounds targeting transcriptional regulation
Transcriptional regulation plays key physiological functions in body growth and development. Transcriptional dysregulation is one of the important biomarkers of tumor genesis and progression, which is involved in regulating tumor cell processes such as cell proliferation, differentiation, and apoptosis. Additionally, it plays a pivotal role in angiogenesis and promotes tumor ...read more
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 that aid in stabilizing chromosomal makeup. The resynthesis of telomeres is supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no telomerase activity in human somatic cells, but the stem cells and germ cells undergo ...read more
