Pharmacognosy of Vinca Alkaloids (Periwinkle)
Vinca alkaloids are obtained mainly from a species of periwinkle known as Madagascar Periwinkle. Vinca alkaloids are chemically indole alkaloids and are known to possess anti-cancer, anti-hypertensive and anti-diabetic roles.

Matrix Metalloproteinases: Its Implications in Cardiovascular Disorders
Matrix metalloproteinases (MMP), which are an integral part of the extracellular matrix’s enzymatic arsenal, play a major role in most of these diseases. Imbalance in the levels of MMP and TIMP plays a major role in the development of pathological conditions.

Glycolysis – Animation and Notes
Glycolysis is the most critical phase in glucose metabolism during cellular respiration. The term “glycolysis” literally means breakdown of glucose and sugars. Biochemically, it involves the breakdown of glucose to pyruvate (or pyruvic acid) via a series of enzymes.

A Review of Polymorphism and the Amorphous State in the Formulation Strategy of Medicines
Polymorphs arise when molecules of a compound attain different conformations with differing energies of stabilization. Although their chemical properties may be same but they differ in their structural orientation. Polymorphism transitions are important to study in pharmaceutical sciences.

A Primer on Measuring Concentrations – Molarity, Moles and Other Confusing Stuff
Being pharmacy and pharmaceutical science students, we face concentrations all around us in some form or the other. This article is aimed to guide you better on how you can do the calculations and understand what is going on while calculating concentrations. We start off with the definition of Avagadro’s Number, cover gram molecular weight, moles, molarity etc. and will end with real life example problems with solutions which you can use to practice your calculations with.
