Racemases: The hunt for drugs to neutralise these critical enzymes

The scientists also propose new strategies for finding drugs that neutralise these enzymes. Many racemases and epimerases perform vital roles in human and animal cells, and in disease-causing organisms. They facilitate proper nerve function, the degradation of toxic substances, the formation of bacterial cell walls and the conversion of certain drugs into their active form (the best known conversion is seen with ibuprofen, which is taken as a mixture of isomers and converted in the liver to the active S-isomer). But while normal levels of racemase and epimerase function are generally beneficial, increased levels can be harmful. Because of this, there is considerable interest in

Prostate Cancer UK criticises decision to reject hormone therapy

Prostate Cancer UK has criticised the National Institute for Health and Care Excellence (Nice) over its interim decision to reject the use of a hormone therapy for men with the disease. The charity warned the rejection of apalutamide could leave thousands of men each year without access to a life-extending treatment. It said this is the second rejection in six months of a new treatment that could help men newly diagnosed with advanced prostate cancer. According to the charity, the new treatments are particularly important for patients who cannot receive the standard treatment of docetaxel chemotherapy. This is more likely to affect older men and those with other health conditions and will also affect anyone whose cancer has progressed from localised disease.
