Experimental drug shows promise for opioid withdrawal symptoms: In rats, rapastinel reverses signs of withdrawal with no side effects

While medicines are available to relieve withdrawal symptoms in people recovering from opioid addiction, they cause side effects and can maintain the brain changes that led to addiction in the first place, which can lead to relapse before treatment is completed. New research offers hope that a better solution may be on the horizon. Rapastinel, … Read more

New discovery provides key to side effects caused by erectile dysfunction drugs

In a study published in Science Advances magazine, researchers from the University of California, Irvine have captured, for the first time, the full-length structure of the rod photoreceptor phosphodiesterase 6 (PDE6), an enzyme that plays an indispensable role in human vision. PDEs are associated with various diseases and are targets of several widely used drugs … Read more

Scientists use a promiscuous inhibitor to uncover cancer drug targets

Scientists at Harvard Medical School and the Dana-Farber Cancer Institute have developed a method that exploits the multitargeted nature of a chemical inhibitor to pinpoint vulnerabilities within cancer cells. When signaling pathways within cells are triggered, proteins activate through a chain reaction, like a row of tumbling dominoes, until the final protein influences some cellular … Read more

Alcohol use disorder: Brain damage may progress despite sobriety

A new study goes against the grain of previous research by suggesting that alcohol-induced brain damage does not stop when alcohol use ends. Instead, the harmful effects of alcohol may continue during abstinence. The findings have important implications for the process of recovery from alcohol dependence. The effects of excessive alcohol use may last much … Read more
