Piperacilloic acid is a synthetic compound that exhibits antibacterial activity. It has been shown to be effective against human pathogens, including urothelial carcinoma and human serum. Piperacilloic acid binds to the amino acids lysine and arginine in bacterial proteins and inhibits protein synthesis by inhibiting the function of enzymes that require these amino acids for their activity. The potency of piperacillin is low, but it is activated by hydrolysis in the acidic environment of the stomach or intestinal tract. Piperacilloic acid also has potential as a contraceptive agent because it may inhibit transcriptional regulation of genes that are involved in sperm production.

Simvastatin acid is the active form of simvastatin, a drug used to lower blood cholesterol levels. Simvastatin acid inhibits HMG-CoA reductase, the enzyme that converts HMG-CoA to mevalonate. This conversion is a rate-limiting step in the synthesis of cholesterol and other lipids. Simvastatin acid binds to polymerase chain and drug transporter proteins, which leads to cell lysis. The concentration–time curve for simvastatin acid is linear and the half-life is approximately 12 hours. When simvastatin acid is administered with drugs that are potent inducers of CYP3A4 or UGT1A1 enzymes, there may be an increased risk for drug interactions. Simvastatin acid has shown no significant human pharmacokinetic interactions with food or grapefruit juice at doses up to 200 mg/day. There are limited data on the pharmacokinetics of simvastatin
