Scientists Get Insight Into New Understanding Of Antibiotic Synthesis

Scientists at Faculty of Medicine from McGill University have made essential strides in knowing the working of enzymes that have an integral part in the making of therapeutics and other antibiotics. Their results are posted in Science.

“Many of the medications that we depend on now are natural goods, created by the flora of Earth,” claims Dr. Martin Schmeing, the senior author of the study. “This comprises compounds created in microbes by huge enzymes dubbed as NRPSs, or nonribosomal peptide synthetases. The NRPSs synthesize all kinds of antibiotics, which can slay hazardous bacteria and fungi, as well as compounds to assist us deal with cancers and viral infections. For instance, these compounds comprise cyclosporin, which has been used widely in organ transplants as an immunosuppressant; viomycin, an antibiotic employed for the cure of multidrug-resistant tuberculosis; and penicillin, the well-known antibiotic.”

In order to manufacture these drugs, NRPSs work same as an assembly line in a factory, consisting of a portfolio of workstations. Every station, dubbed as a “module,” has moving parts and multi-step workflows that allow it to include one building block element to the developing drug.

On a related note, new research posted in the Canadian Medical Association Journal (CMAJ) this week shows that discount cards for brand-name drug are leading to elevated health care investment in Canada—elevated prices that are eventually passed on to patients.

Discount cards for brand-name drug—also dubbed as co-pay cards—are coupons provided by brand drug makers to motivate patients to employ brand-name drugs even after much more affordable generics become accessible. In spite of often boasting savings for users, though, the findings of the study show discount cards for drug actually elevated private insurer prices by 46% and public insurer prices by 1.3%, versus if patients brought generics rather.
