Plumbagin, a naphthoquinone derived from the medicinal plant Plumbago zeylanica has been shown to exert anticancer and anti-proliferative activities in cells in culture as well as animal tumor models. In our previous paper, we have reported the cytotoxic action of
Highly diastereoselective C(sp3)-C(sp) cross-coupling reactions between 1,3- and 1,4-substituted cyclohexylzinc reagents and bromoalkynes through remote stereocontrol.

A novel on-line HPLC-cupric reducing antioxidant capacity (CUPRAC) method was developed for the selective determination of polyphenols (flavonoids, simple phenolic and hydroxycinnamic acids) in complex plant matrices. The method combines chromatographic separation, constituent analysis, and post-column identification of antioxidants in

S-nitrosylation of proteins serves an important role in regulating diverse cellular processes including signal transduction, DNA repair, and neurotransmission. Identification of S-nitrosylation sites is crucial for understanding the significance of this post-translational modification (PTM) in modulating the function of a
Hydroxyl radicals (OH) generated in the human body may play an important role in tissue injury at sites of inflammation in oxidative stress-originated diseases. As a more convenient, efficient, and less costly alternative to HPLC/electrochemical detection techniques and to the
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
