Molecular tribology

It’s hard to imagine more intriguing title in Angewandte Chemie International Edition than “Astringent Mouthfeel as a Consequence of Lubrication Failure“. The first impression doesn’t deceive, and the paper is really interesting and fun to read. Somehow manifestations of molecular interactions in the macroscopic world never stop amusing me. And this communication is exactly about such emergent effect. Continue reading “Molecular tribology”

MedChem shortcuts

Simplification of complex structures is one way medicinal chemists avoid lengthy (and risky) synthetic routes to the analogs of natural products. And it’s absolutely rational, if one can get the same pharmacological effect with a simple molecule, why bother making a complex 3D scaffold? One classic med-chem textbook example is simplification of morphine scaffold to pethidine that led eventually to the development of fentanyl.
