New Discovery Sheds Light on How Monoamines Regulate Brain Rhythms

A collaborative effort between Mount Sinai and Memorial Sloan Kettering Cancer Center has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of these monoamines to histone proteins, the core DNA-packaging proteins of our cells.

New Model for Studying Ebola Virus Pathogenesis

Ebola is a fatal hemorrhagic disease caused by a virus that is found in parts of East-Central and West Africa. Most individuals are aware that the major mode of person-to-person transmission is through contact with an infected person’s bodily fluids.

A Novel Method for Synthesizing Piperidines for Modern Medicine

A team of chemists from Scripps Research and Rice University has unveiled a novel method to simplify the synthesis of piperidines, a key structural component in many pharmaceuticals. The study, published in Science, combines biocatalytic carbon-hydrogen oxidation and radical cross-coupling, offering a streamlined and cost-effective approach to create complex, three-dimensional molecules.
