Pharmacological Features and Therapeutic Implications of Plumbagin in Cancer and Metabolic Disorders: A Narrative Review.

Plumbagin (PLB) is a naphthoquinone extracted from . In recent times, there has been a growing body of evidence suggesting the potential importance of naphthoquinones, both natural and artificial, in the pharmacological world. Numerous studies have indicated that PLB plays a vital role in combating cancers and other disorders.

Sequence and structure-based method to predict diacylglycerol lipases in protein sequence.

Lipase enzymes play a central role in biotechnology and the food industry. Diacylglyceride lipases (DAG) have received considerable attention due to their physiological significance and potential industrial usage. However, compared to the wide application of triacylglycerol (TAG) lipases, DAG lipases have a limited application due to their low thermostability and specific activity.

Molecular modeling and simulation of the human eNOS reductase domain, an enzyme involved in the release of vascular nitric oxide.

Homology modeling of the reductase domain of endothelial nitric oxide synthase (eNOS), which regulates the catalytic activity of eNOS, and molecular dynamics studies focusing especially on the serine residues S615, S633, and S1177 were performed. MD analysis of this structure revealed that S633 is highly flexible and accessible to solvent molecules, while S1177 becomes highly flexible when S633 is phosphorylated. The presence of intramolecular interactions between S1177 among the major serine residues underscores its structural importance to the efficient synthesis of nitric oxide in endothelium.
