Immunostimulatory potential and proteome profiling of Leishmania donovani soluble exogenous antigens.

Isolation of the soluble exogenous antigens (SEAgs), its immune response study and proteome profiling is an essential prerequisite for understanding the molecular pathogenesis of Leishmania donovani. The immunostimulatory potential of L. donovani SEAgs, purified from culture of L.

Synthesis of novel 3-carboxamide-benzocoumarin derivatives as orally active antithrombotic agents.

In an effort to develop potent antithrombotic agents, a series of novel 3-carboxamide-benzocoumarin derivatives were synthesized and screened for their in vivo antithrombotic activity. Among 20 compounds tested, the compound 12b showed the most promising antithrombotic activity which was comparable with clinically used aspirin or warfarin, but, at variance with these standard drugs, 12b did not exhibit the increased bleeding time, suggesting its potential as a novel antithrombotic agent.

Antiproliferative action of Xylopia aethiopica fruit extract on human cervical cancer cells.

The anticancer potential of Xylopia aethiopica fruit extract (XAFE), and the mechanism of cell death it elicits, was investigated in various cell lines. Treatment with XAFE led to a dose-dependent growth inhibition in most cell lines, with selective cytotoxicity towards cancer cells and particularly the human cervical cancer cell line C-33A. In this study, apoptosis was confirmed by nuclear fragmentation and sub-G(0)/G(1) phase accumulation.
