Madangamines are a group of polycyclic alkaloids from marine sponges which have biomedical interest due to their cytotoxic activity. Chemists have now completed the first total synthesis of madangamine D, a scientific discovery in the field of organic chemistry.
Batteries do not age gracefully. The lithium ions that power portable electronics cause lingering structural damage with each cycle of charge and discharge, making devices from smartphones to tablets tick toward zero faster and faster over time. To stop or slow this steady degradation, scientists must track and tweak the imperfect chemistry of lithium-ion batteries […]
A direct method to single enantiomer PET tracers has been developed by scientists. These radioactive small molecules are used in PET scans to help doctors visualize the progression of disease. Ultimately the goal is to use this chemistry to identify a completely novel PET radiotracer for imaging.
