The Quinoline Photoremovable Group (PPG) Platform—A Medicinal Chemist's Approach for Photocage Development and Applications

Medicinal Research Reviews, EarlyView.
ABSTRACT Photoremovable protecting groups (PPGs) offer a straightforward solution for the temporary inactivation of biologically active substrates and their subsequent controlled release by light irradiation. Their relatively easy design and mode of application have made them useful tools for studying dynamic biological processes in vitro and in vivo ...

The Antiviral Activity of Polyphenols

Molecular Nutrition &Food Research, EarlyView.
Polyphenols demonstrate remarkable antiviral properties by effectively disrupting multiple biochemical processes essential for viral replication. ABSTRACT Polyphenols are secondary metabolites produced by a large variety of plants. These compounds that comprise the class of phenolic acids, stilbenes, lignans, coumarins, flavonoids, and tannins have a ...

Placebo‐Controlled, Randomized Double‐Blind N‐Of‐1 Trial to Study Safety and Potential Efficacy of TJ‐68 for Improving Muscle Cramps in Patients With Amyotrophic Lateral Sclerosis: A Pilot Study

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Muscle cramps are a common symptom in amyotrophic lateral sclerosis (ALS). Ameliorating muscle cramps may improve quality of life in devastating diseases like ALS. A traditional Japanese medicine (Kampo, TJ‐68) is widely prescribed in Japan for muscle cramps. However, it is not available in the USA.

A survey of generic names in Rubiaceae (Gentianales) with notes on context and patterns in naming

TAXON, EarlyView.
Abstract Rubiaceae is one of the most diverse angiosperm families and consequently is the topic of much systematic research. Plenty of literature exists on the familial, tribal, and species level; however, a comprehensive overview of the names at the generic level is lacking. The aim of this study is to present a survey of all names and designations at
