Anti-Influenza Prodrug Oseltamivir Is Activated by Carboxylesterase Human Carboxylesterase 1, and the Activation Is Inhibited by Antiplatelet Agent Clopidogrel
Deshi Shi,Jian Yang,Dongfang Yang,Edward L. LeCluyse,Christopher B. Black,Li You,Fatemeh Akhlaghi,Bingfang Yan +7 more
TL;DR: Con concurrent use of both drugs would inhibit the activation of oseltamivir, thus making this antiviral agent therapeutically inactive, which is epidemiologically of significance because people who receive osel Tamsivir and clopidogrel simultaneously may maintain susceptibility to influenza infection or a source of spreading influenza virus if already infected.
Journal ArticleDOI
Antiplatelet Agents Aspirin and Clopidogrel Are Hydrolyzed by Distinct Carboxylesterases, and Clopidogrel Is Transesterificated in the Presence of Ethyl Alcohol
Man Tang,Madhu Mukundan,Jian Yang,Nathan Charpentier,Edward L. LeCluyse,Christopher B. Black,Dongfang Yang,Deshi Shi,Bingfang Yan +8 more
TL;DR: The isoform-specific hydrolysis of aspirin and clopidogrel suggests that these two antithrombogenic agents may have pharmacokinetic interactions with different sets of ester drugs, and the altered Hydrolysis by polymorphic mutants provides a molecular explanation to the interindividual variation.
Journal ArticleDOI
Human carboxylesterases HCE1 and HCE2: Ontogenic expression, inter-individual variability and differential hydrolysis of oseltamivir, aspirin, deltamethrin and permethrin
TL;DR: A large inter-individual variability was detected in mRNA, protein, protein and hydrolytic activity within the same age group, particularly in the fetal and child groups, and this has important pharmacological and toxicological implications.
Journal ArticleDOI
The expression of antiapoptotic protein survivin is transcriptionally upregulated by DEC1 primarily through multiple sp1 binding sites in the proximal promoter
TL;DR: Findings establish that the survivin gene is a transcription target of DEC1, and induction of survivin is at least in part responsible for DEC1 antiapoptosis.
Journal ArticleDOI
Abundant expression of Dec1/stra13/sharp2 in colon carcinoma: its antagonizing role in serum deprivation-induced apoptosis and selective inhibition of procaspase activation.
TL;DR: The results functionally distinguish DEC1 from other bHLH proteins and directly link this factor to oncogenesis.
