Designing of biocompatible and biodegradable chitosan based crosslinked hydrogel for in vitro release of encapsulated povidone-iodine: A clinical translation.

Controlled drug delivery is a prime stratagem for minimizing both the frequency of therapeutic administration as well as systematic side effects with high drug content. One of the extensively studied approaches for controlling medicament delivery is the encapsulation of drug within polymer chains which sluggish the release on the basis of its crosslinked network. Recent advances in biomedical field have led to the fabrication of chitosan (CS) based biocompatible and biodegradable hydrogels for controlled delivery of encapsulated drug.

Identification of Hypotensive Biofunctional Compounds of and Evaluation of Their Angiotensin-Converting Enzyme (ACE) Inhibition Potential.

The aim of this study was to identify and characterize the bioactive compounds of responsible for the treatment of hypertension and to explore their mechanism of action as angiotensin-converting enzyme (ACE) inhibitors. Bioactive fractions like alkaloids, flavonoids, steroids, and tannins were extracted and evaluated for their ACE inhibition potential. Among them, only flavonoid-rich fraction showed high ACE inhibition potential with IC value of 28.
