Researchers revisit potent drug as promising treatment for acute leukemia

by National University of Singapore Chemical screening using the GIMAP enhancer reporter system. (A) Overview of the chemical screening strategy. Using a liquid handling workstation, 2,961 compounds from 3 chemical libraries, a negative control (dimethyl sulfoxide [DMSO]) and a positive control (THZ1), were added to Jurkat cells that stably expressed the GIMAP enhancer reporter construct....

CAN A COUGH SYRUP DRUG HELP PEOPLE QUIT SMOKING?

The researchers developed a new machine learning method, where computer programs analyze data sets for patterns and trends, to identify the drugs and say that some of them are already being tested in clinical trials. Cigarette smoking is risk factor for cardiovascular disease, cancer, and respiratory diseases and accounts for nearly half a million deaths in the United...

Fresh questions about oxytocin as the ‘love hormone’ behind pair bonding

by University of California, San Francisco CPK model of the Oxitocin molecule. Credit: CC0 Turning a decades-old dogma on its head, new research from scientists at UC San Francisco and Stanford Medicine shows that the receptor for oxytocin, a hormone considered essential to forming social bonds, may not play the critical role that scientists have assigned to...

Another promising step toward non-hormonal male contraceptives

by American Chemical Society Graphical abstract. Credit: Journal of Medicinal Chemistry (2023). DOI: 10.1021/acs.jmedchem.2c01731 Despite birth control existing for decades, almost none of the options specifically target sperm cells. Researchers are now developing approaches that target testosterone or otherwise interrupt the sperm’s ability to fertilize an egg, yet these may not work for everyone. But now, researchers publishing in the Journal of...
