Azadirachtin B increases expression of RunX-2 -2.5 fold at 10nM concentration, ALP expression -2.8 fold at 10nM and 100pM concentration and OCN expression -2.5 folds at 10nM as compared with control. Azadirachtin B (Compound 4) exhibits toxicity to the diamondback moth (Plutella xylostella) with an LD50 of 4.85-1.06 µg/g body weight, in 92 h. Azadirachtin B (compound 21) exhibits moderate or potent inhibitory effects (IC50 value of 384 mol ratio/32pMol TPA) against the Epstein-Barr virus early antigen (EBV-EA) activation induced by tetradecanoylphorbol-13-acetate (TPA) Cell Proliferation Assay Cell Line: Osteoblast cells Concentration: 1pM, 100pM, 10nM, 1µM, 100µM Incubation Time: 48 hours Result: Showed highest proliferation at 10nM and 100pM concentrations in osteoblast cells. 体内研究 On evaluation of Azadirachtin B (compound 21; oral administration) for its anti-tumor-initiating activity on the two-stage carcinogenesis of mouse skin tumor induced by peroxynitrite (ONOO-; PN) as an initiator and TPA as a promoter, this exhibited marked inhibitory activity |
