In Vitro and Clinical Evaluation of Potential Interactions of Bemnifosbuvir with Drug‐Metabolizing Enzymes

open access: yesThe Journal of Clinical Pharmacology, Volume 66, Issue 5, May 2026.
Abstract Bemnifosbuvir is a novel oral guanosine nucleotide prodrug with potent pan‐genotypic inhibitory activity against hepatitis C virus. In vitro studies assessing the inhibition or induction potential of bemnifosbuvir on the CYP450 and UGT1A1 enzymes demonstrated that bemnifosbuvir is a weak inducer and a reversible and time‐dependent inhibitor of

Feed-Forward Inhibition of CD73 and Upregulation of Adenosine Deaminase Contribute to the Loss of Adenosine Neuromodulation in Postinflammatory Ileitis

open access: yesMediators of Inflammation, 2014
Purinergic signalling is remarkably plastic during gastrointestinal inflammation. Thus, selective drugs targeting the “purinome” may be helpful for inflammatory gastrointestinal diseases. The myenteric neuromuscular transmission of healthy individuals is

Cyclic AMP Receptor Protein from Yeast Mitochondria [PDF]

open access: yes, 1985
We have identified and characterized a cyclic AMP receptor protein in mitochondria of the yeast Saccharomyces cerevisiae. The binding is specific for cyclic nucleotides, particularly for cyclic AMP which is bound with high affinity (Kd of 10(-9) M) at 1 ...
