ABSTRACT
Solanum Nigrum is a kind of dicotyledon solanaceae annual herb, and alkaloids are its main bioactive constituents, with good antitumor activity. The current extraction methods for alkaloids include solvent extraction, ultrasonic extraction, microwave extraction, supercritical fluid extraction, and column chromatography etc, while the detection methods include acid dye colorimetry, thin layer scanning, high performance liquid chromatography, reversed-phase high performance liquid chromatography, and ultra-high performance liquid chromatography etc. This article reviewed the research progress in extraction and detection methods of alkaloid from Solanum Nigrum in recent years, so as to provide references for further research and development of alkaloid from Solanum Nigrum.
ABSTRACT
The success of ATRA and ATO in APL treatment furuishes the first model of molecular target-based induction of differentiation and apoptosis.Two drugs all target PML-RARα oncoprotein through different moieties and induce APL cells differentiation and apoptosis.In acute myeloid leukemia M2b,we reveal that gain-of-function of C-kit coexists with persistent AML1-ETO,suggesting that abnormal C-kit may serve as a therapeutic target in AML L-M2b Oridonin becomes a potential candidate target drug which specifically degrades AML1-ETO protein. Experiment in vitro proves the combinatorial effectiveness of imatinib and cytarabin in the treatment of chronic myelogenous leukemia(CML).Imatinib is an inhibitor of abnormal protein tyrosine kinases activity. While arsenic agent triggers the degradation of bcr-abl, and combination of the two drugs in treating CML leads to a better outcome.
