Gallic acid blocks dissociation by stabilizing oligomers against this process. Certain tumor types have an increased capacity for heme synthesis, which serves as the basis for photodynamic therapy. These studies suggest that heme may serve as a novel therapeutic target for cancer drug discovery. Chemical mitochondrial uncouplers are lipophilic weak acids that increase proton transport into the mitochondrial matrix via a pathway independent of ATP synthase, thereby uncoupling nutrient oxidation from ATP production. To identify new mitochondrial uncouplers that lack off-target activity at the plasma membrane, we screened a small molecule chemical library. HIV-1 resistance to zidovudine [AZT ] is associated with selection of the mutations M41L, D67N, K70R, L210W, T215F/Y and K219Q/E in RT . Although AZT-MP excision occurs at the enzyme’s polymerase active site, it is mechanistically distinct from the DNA polymerase reaction.

Citing the federal government’s extension program, the AMA sent letters to the FDA, the U.S. Pharmacopeial Convention, which sets standards for drugs, and PhRMA asking for a re-examination of expiration dates.

Sildenafil is available as a generic drug in the United States, labeled for pulmonary arterial hypertension. As of 2016 branded pills cost about 50 times more than generic ones. In 2000, Viagra sales accounted for 92% of the global market for prescribed erectile dysfunction pills.

Then there’s the added angst of tossing drugs that are in short supply. Berkowitz picks up a box of sodium bicarbonate, which is crucial for heart surgery and to treat certain overdoses. He holds up a purple box of atropine, which gives patients a boost when they have low heart rates. In the federal government’s stockpile, the expiration dates of both drugs have been extended, but they have to be thrown away by Berkowitz and other hospital pharmacists. At Newton-Wellesley, Berkowitz keeps a spreadsheet of every outdated drug he throws away. “I question the expiration dates on most of these drugs,” Berkowitz says.

Greg Burel, director of the CDC’s stockpile, says he worries that if drugmakers were forced to extend their expiration dates it could backfire, making it unprofitable to produce certain drugs and thereby reducing access or increasing prices. Four scientists who worked on the FDA extension program told ProPublica something like that could work for drugs stored in hospital pharmacies, where conditions are carefully controlled. Berkowitz says he appreciated Pfizer’s action, but feels it should be standard to make sure drugs that are still effective aren’t thrown away. David Berkowitz, assistant director of the pharmacy at Newton-Wellesley Hospital, said he questions the validity of many drug expiration dates.
