Analysis of pharmacological mechanisms and targets mining of Wuzi-Yanzong-Wan for treating non-obstructive oligoasthenospermia
As a classical traditional Chinese medicine, Wuzi-Yanzong-Wan (WZYZW) has been widely applied for several centuries to treat non-obstructive oligoasthenozoospermia (NOA), although its pharmacological mechanisms remain largely unknown.
Quantitative Analysis of Tozadenant Using Liquid Chromatography-Mass Spectrometric Method in Rat Plasma and Its Human Pharmacokinetics Prediction Using Physiologically Based Pharmacokinetic Modeling
Tozadenant is one of the selective adenosine A2a receptor antagonists with a potential to be a new Parkinson’s disease (PD) therapeutic drug. In this study, a liquid chromatography-massspectrometry ...
Cu-mediated synthesis of differentially substituted diazepines as AChE inhibitors; validation through molecular docking and Lipinski’s filter to develop novel anti-neurodegenerative drugs
A highly efficient Cu-mediated route for the synthesis of fused [1,2,3]triazolo[1,4]diazepines has been developed by azidation-cyclization of 2-bromo-N-propargylamines in a one-pot fashion.
Enabling Personalized Medicine Through Pharmacokientic Modeling
Personalized medicine strives to deliver the ‘right drug’ at the ‘right dose’ at the ‘right time’ by considering the unique characteristics that define specialized populations of patients and contribute to inter-individual variability...
