In a document, author is Shakeel-u-Rehman, introduce the new discover, Recommanded Product: 3-Bromo-2-fluoroaniline.
Click chemistry inspired facile synthesis and bioevaluation of novel triazolyl analogs of D-(+)-pinitol
Cu (I)-catalyzed alkyne-azide cycloaddition was carried out for the preparation of novel 1,4-disubstituted 1,2,3-triazoles of D-(+)-pinitol. All the analogs were screened for cytotoxicity against promyelocytic leukemia (HL-60), colorectal carcinoma (HCT 116) and pancreatic carcinoma (Mia-Paca-2) cancer cell lines using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cytotoxicity assay. Compounds 2, 3 and 7 showed the best activity with IC50 of 19.2, 17.5 and 16.4 mu M against leukemia (HL-60), colorectal carcinoma (HCT 116) and pancreatic carcinoma (Mia-Paca-2) cell lines respectively. All the triazolyl analogs were further evaluated for b-glucosidase inhibitory activity, wherein, the deprotected derivatives: 6a, 18a and 25a showed better activity with IC50 of 148.5, 139.2 and 142.4 mu M respectively. The structure activity relationship (SAR) studies revealed that the analogs with bromo, nitro or methyl groups in R (substituted phenyl moiety attached to 1,2,3-triazole) moiety exhibited better cytotoxicity, while as, the analogs with N-substituted long chain aliphatic hydrocarbon R moieties displayed effective beta-glucosidase inhibition.
