Study indicates how drug efficacy can be increased by manipulating the signalling mechanism

Researchers believe they have found a way to change the action of 60 percent of currently available medications, in some cases making them many times more effective, according to an article published in the April 21 edition of the journal Science. The discovery has the potential to improve treatments for diseases including heart disease, cancer, diabetes, depression and arthritis. The study describes a new way to manipulate perhaps the most important signaling mechanism in human cells: G-protein coupled receptors (GPCRs).

Research into toxins points to development of better medicines

Researchers have combined magnetic resonance spectroscopy with special protein synthesis procedures to uncover how potassium channels and toxins combine and change in structure. This work could make it possible to develop medications for high blood pressure and many other diseases connected to potassium channel failure .
