Propensity of salicylamide and ethenzamide cocrystallization with aromatic ca...Maciej Przybyłek
The cocrystallization of salicylamide (2-hydroxybenzamide, SMD) and ethenzamide (2-ethoxybenzamide, EMD) with aromatic carboxylic acids was examined both experimentally and theoretically. The supramolecular synthesis taking advantage of the droplet evaporative crystallization (DEC) technique was combined with powder diffraction and vibrational spectroscopy as the analytical tools. This led to identification of eleven new cocrystals including pharmaceutically relevant coformers such as mono- and dihydroxybenzoic acids. The cocrystallization abilities of SMD and EMD with aromatic carboxylic acids were found to be unexpectedly divers despite high formal similarities of these two benzamides and ability of the R2,2(8) heterosynthon formation. The source of diversities of the cocrystallization landscapes is the difference in the stabilization of possible conformers by adopting alternative intramolecular hydrogen boding patterns. The stronger intramolecular hydrogen bonding the weaker affinity toward intermolecular complexation potential. The substituent effects on R2,2(8) heterosynthon properties are also discussed.
In-Silico Analysis and Docking of Human Serum Protein with Quercetin in T2DMIRJET Journal
This document describes an in silico analysis of the interaction between the flavonoid quercetin and human serum albumin (HSA) protein. The study retrieved the structures of quercetin from PubChem and HSA from the Protein Data Bank. AutoDock software was used to dock quercetin to HSA, which produced a binding energy of -9.2 kcal/mol, indicating a stable interaction. This interaction between quercetin and HSA may help stimulate insulin production in pancreatic cells, lowering blood glucose in type 2 diabetes patients. Therefore, consuming quercetin-rich foods may help reduce diabetes risk factors.

Deserts are expanding across large parts of the world due to various human and environmental factors. Overgrazing of livestock and deforestation have degraded soils, reducing their ability to retain water. Climate change has exacerbated droughts in many regions, reducing rainfall and causing desertification. As deserts expand, they threaten the livelihoods of those living in increasingly arid lands and could contribute to conflicts if populations are forced to migrate. Understanding and addressing the root causes, such as sustainable land management practices and reducing greenhouse gas emissions, is essential to slow the spread of deserts.
