In an ongoing search for cancer-preventing compounds derived from plant sources, we isolated the quinolin-2,4-dione alkaloid severibuxine from the root bark of Severinia buxifolia collected in Taiwan and then examined the apoptotic effect of this compound. Severibuxine showed cytotoxicity to leukemia HL-60 cells (IC50 = 12.3±0.6 μM). Fluorescence microscopic analysis of cells stained with Hoechst 33342 indicated that the percentage of apoptotic cells showing nuclear condensation and fragmentation increased in a time-dependent manner. In addition, the activities of caspase-9 and caspase-3 were also enhanced in a time-dependent manner upon treatment with severibuxine. The addition of caspase-9 and caspase-3 inhibitors blocked severibuxine-mediated apoptosis. Upon treatment with severibuxine, the mitochondrial membrane potential decreased in a time-dependent manner. Severibuxine induced apoptosis in HL-60 cells through activation of the caspase-9/caspase-3 pathway, which is triggered by mitochondrial dysfunction.

The suspensions of alcoholic extract of root bark of the plant Calotropis gigantea in 0.6% carboxy methyl cellulose (CMC) were evaluated for hepatoprotective activity in Wistar albino rats by inducing hepatic injury with D-galactosamine (400 mg/kg). Alcoholic extract of root bark of the plant Calotropis gigantea at an oral dose of 200 mg/kg and 400 mg/kg exhibited a significant (P<0.001, P<0.01 and P<0.05) protection effect by normalizing the levels of aspartate amino transferase (ASAT/ GOT), alanine amino transferase (ALAT/GPT), alkaline phosphatase (ALP), total bilirubin (TB), lactate dehydrogenase (LDH), which were significantly (P<0.001) increased in rats by treatment with 400 mg/kg i.p. of D-galactosamine. Silymarin (25 mg/kg), a known hepatoprotective drug used for comparison exhibited significant activity (P<0.001).
