These were screened for their anticancer activity against different cancer cells and normal human PBMC by MTT assay. Compound 2c [(3S)-3-2-(4-(hydroxymethyl-1H-1,2,3-triazol-1-yl)acetyloxy}-lup-20(29)-en-28-oic acid] was found as the most potent inhibitor of cell line HT-29 with IC50 value 14.9 μM. Its role as an inducer of apoptosis was investigated in this cell line by Annexin-V/PI binding assay and
A series of 1, 2, 3-triazole-based betulinicacidderivatives d1–d31 were synthesized as α-glucosidaseinhibitors with hypoglycemic activity. All the derivatives exhibited excellent inhibition against α-glucosidase, and compound d23 was the most active (IC50 = 2.83 ± 0.19 μM). Inhibition kinetics showed that compound d23 was a mixed-type inhibitor for α-glucosidase. Spectroscopic studies based on 3D
