Azadirachtin B is an azadirachtin that has been found in the neem tree, A. indica, and has diverse biological activities, including insecticidal, nematocidal, anticancer, and osteogenic properties.{46667,46668,46669,46670,46671} It has antifeedant activity against P. xylostella third instar larvae when used at a concentration of 3 mg/ml and induces mortality with an LC50 of 1.03 mg/ml.{46668} It induces mortality in M. incognita second instar larvae with an LD50 value of 125.8 ppm.{46669} Azadirachtin B (780 nmol in the drinking water) reduces the number of papillomas formed on mouse skin in a model of skin carcinogenesis induced by peroxynitrite and phorbol 12-myristate 13-acetate (TPA; Item No. 10008014) but is not cytotoxic to HL-60, A549, AZ521, SK-BR-3, or CRL1579 cancer cells (IC50s = >20 µM for all).{46670,46671} It induces osteoblast differentiation and increases the rate of osteoblast proliferation in primary calvarial osteoblast cells when used at concentrations of 100 pM and 10 nM but not 1 pM, 1 µM, or 100 µM.{46667}
