TL;DR: Safe and economically cheaper uses of different parts of neem in the treatment of various diseases and in agriculture are discussed and active chemical constituents of various neem formulations are dealt with.

TL;DR: A simple, straightforward, and highly efficient multicomponent one-pot synthesis of a pharmaceutically interesting diverse kind of functionalized 2-amino-3-cyano-4H-pyrans and pyran-annulated heterocycles has been developed based on a low-cost and environmentally benign commercially available urea as a novel organo-catalyst as mentioned in this paper.

TL;DR: In this paper, a simple, straightforward, and highly efficient diastereoselective multicomponent one-pot synthesis of a series of pharmaceutically interesting functionalized piperidine derivatives has been developed based on a low-cost and environmentally benign Bi(NO3)3·5H2O catalyst via tandem reactions of 1,3-dicarbonyl compounds, aromatic aldehydes, and various amines in ethanol at room temperature.

TL;DR: In this article, natural distribution of stevioside and related compounds, their structural features, plausible biosynthetic pathways along with an insight into the structure–sweetness relationship are presented.

TL;DR: The botanical classification and ethno‐pharmacology of Swertia plants, as well as the biological activities and pharmacological applications of both distinct phytochemicals and medicinally acitve plant materials (formulations, extracts, etc.) are discussed in detail.
