生物活性:
Azadirachtin B is an limonoid isolated from seed kernels of Azadirachta indica. Azadirachtin B increases alkaline phosphatase (ALP) activity and stimulates osteoblast differentiation. Azadirachtin B is active against the Epstein-Barr virus early antigen (EBV-EA). Azadirachtin B has insecticidal, nematocidal, anticancer, anti-inflammatory, antiviral and osteogenic properties.
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.
体外研究:
Azadirachtin B (1 pM-100 μM; 48 hours; Osteoblast cells) treatment shows highest proliferation at 10 nM and 100 pM concentrations in osteoblast cells. Azadirachtin B increases expression of RunX-2 ~2.5 fold at 10 nM concentration, ALP expression ~2.8 fold at 10 nM and 100 pM concentration and OCN expression ~2.5 folds at 10 nM 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/32 pmol TPA) against the Epstein-Barr virus early antigen (EBV-EA) activation induced by tetradecanoylphorbol-13-acetate (TPA).
