Plutella xylostella
Alkaline phosphatase (ALP)
Epstein-Barr virus early antigen (EBV-EA)
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 LD
50
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).
Cell Proliferation Assay
| Cell Line: | Osteoblast cells |
| Concentration: | 1 pM, 100 pM, 10 nM, 1 µM, 100 µM |
| Incubation Time: | 48 hours |
| Result: | Showed highest proliferation at 10 nM and 100 pM concentrations in osteoblast cells. |
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.
