Clinically used drugs can adversely affect cardiac function. Doxorubicin (DOX), a chemotherapeutic drug, and efavirenz (EFV), an antiretroviral drug, are known to associate with adverse cardiovascular events and alterations of serum lipid p...
Molnupiravir is not a selective CES2 probe substrate: in vitro evidence for CES1 involvement [0.03%]
莫努匹拉韦不是CES2特异性探针底物:体外证据表明CES1参与其中
Luke Roberts,Hannah Moulton,Xiaofeng Wu et al.
Luke Roberts et al.
Molnupiravir is an orally administered prodrug that requires enzymatic hydrolysis to generate N-hydroxycytidine, a pharmacologically active ribonucleoside analog. Previous reports suggested that molnupiravir hydrolysis was selectively catal...
Neddylation inhibition sensitizes gastric cancer to 5-fluorouracil by targeting the post-translational stability of the metabolic enzyme dihydropyrimidine dehydrogenase [0.03%]
去 neddylation通过靶向代谢酶胸苷酸合成酶的翻译后稳定性使胃癌对氟尿嘧啶敏感化
Qianqian Zhang,Jingyi Hu,Yangbo Liu et al.
Qianqian Zhang et al.
The therapeutic efficacy of 5-fluorouracil (5-FU), a cornerstone of gastric cancer chemotherapy, is predominantly limited by its catabolic inactivation in tumors. Dihydropyrimidine dehydrogenase (DPD) is the rate-limiting enzyme responsible...
Pregnane X receptor, constitutive androstane receptor, or peroxisome proliferator-activated receptor α activation does not affect yes-associated protein phase separation under physiological and hyperosmotic conditions [0.03%]
