Omeprazole-13CD3 (H 16868-13CD3) 是一种 13C 标记和氘代标记 Omeprazole。Omeprazole (H 16868) 是一种质子泵 (proton pump) 抑制剂 (PPI)，有潜力用于胃肠道疾病的研究。Omeprazole 竞争性抑制 CYP2C19 活性，Ki 为 2 到 6 μM。Omeprazole 还抑制革兰氏阳性菌和革兰氏阴性菌生长。Omeprazole 是中性鞘磷脂酶 (N-SMase) 的抑制剂(外泌体抑制剂)。
Omeprazole-13CD3 (H 16868-13CD3) is a 13C-labeled and deuterium labeled Omeprazole. Omeprazole (H 16868), a proton pump inhibitor (PPI), is available for treatment of acid-related gastrointestinal disorders. Omeprazole shows competitive inhibition of CYP2C19 activity with a Ki of 2 to 6 μM[1]. Omeprazole also inhibits growth of Gram-positive and Gram-negative bacteria[2].Omeprazole is a potent brain penetrant neutral sphingomyelinase (N-SMase) inhibitor (exosome inhibitor)[3].
Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].
