Synthesis and cytotoxicity studies of 3,5-diaryl N-acetyl pyrazoline—isatin hybrids
摘要:
Numerous reports highlighting the cytotoxic effects of 3,5-diaryl N-acetyl-pyrazolines and isatin tempted us to synthesise conjugates of the functionalities via alkyl armed triazole tetheration. The hybrids were synthesized by click chemistry approach and were evaluated against a panel of cell lines i.e. viz HeLa (cervix cancer), CAKI-I (Renal cancer), PC-3 (Prostate cancer) and Miapaca-2 (pancreatic cancer). The hybrids were classified into right-handed and left-handed conjugates on the basis of the placement of the isatin ring. The length of the alkyl armed triazole linker was varied from 2 to 6. Structure activity relationship has also been presented. A preliminary cytotoxic assay was performed on the series of 3,5-diaryl N-acetyl-pyrazolines and only the potent 3,5-diaryl N-acetyl-pyrazolines were selected for their inclusion in the hybrid scaffold. Among the cell lines employed, HeLa cell line was the most sensitive towards the exposure of test compounds. Out of all the compounds evaluated, two right-handed conjugates MI-7b and MI-8b and two left-handed conjugates MI-4b, MI-6b displayed significant cytotoxic potential and exhibited an IC50 range from 1.3 to 3.5 mu M against HeLa Cell line..

Xanthineoxidase is a complex molybdoflavoprotein that catalyses the hydroxylation of xanthine to uric acid. Fifty three analogues of 1-acetyl-3,5-diaryl-4,5-dihydro(1H)pyrazoles were rationallydesigned and synthesized and evaluated for in vitro xanthineoxidase inhibitory activity for the first time. Some notions about structure activity relationships are presented. Six compounds 41, 42, 44, 46,
Chalcone is an aromatic ketone that forms the central core for a variety of important biological compounds, which are collectively known as chalcones. The cytotoxic potential of chalcones which consists of C-6-C-3-C-6 units gets enhanced by the incorporation of pyrazole ring as proved by our earlier studies. Thus in the present work, pyrazoles of chalcones with ring A substituted by furan, naphthalene and variety of substituted phenyl rings has been prepared and evaluated for in vitro cytotoxic activity against PC-3, OVCAR, IMR-32, HEP-2 human cancer cell lines.All the synthesized compounds were evaluated for in vitro cytotoxicity against PC-3, OVCAR, IMR-32, HEP-2 human cancer cell lines. Compound 68 was found to be the most potent showing broad spectrum of cytotoxicity against all the cell lines .
