Synthesis and Evaluation of Aryloxy-Acetamide Derivatives as CBX2 Inhibitors
The CBX2 protein plays a key role in the methylation of histone lysine residues related to epigenetic silencing. In contrast to other polycomb paralogs, there are few examples of CBX2 modulators, which prompted us to develop small-molecu...

Sequence- and Base-Selective Modification of mRNA within and nearby Premature Termination Codon and Its Effect on the Translation in a Human Cell-Free Translation System
Single-nucleotide variants represent a major class of disease-causing mutations. Among them, nonsense mutations generate premature termination codons (PTCs), resulting in truncated proteins that are nonfunctional or toxic. Because PTCs a...

NMR Analysis of Complex Formation Underlying the Precipitation of Rosmarinic Acid with Protoberberine Derivatives
Rosmarinic acid (RA), a representative polyphenol, forms insoluble complexes with protoberberine alkaloids (PBAs), leading to precipitate formation. In this study, the precipitation behavior and complex formation between RA and three PBA...

Precipitation Profiles of Dipyridamole in Biorelevant pH-Shift Dissolution Test with Clinically Relevant Dose-to-Fluid Volume Ratio Focusing on Liquid–Liquid Phase Separation
The purpose of this study was to evaluate the precipitation profiles of dipyridamole (DPM) in a biorelevant pH-shift dissolution test under a clinically relevant dose-to-fluid volume (Dose/FV) ratio, focusing on liquid–liquid phase separ...

Enzymatic Deacetylation as a Plausible Final Step in Camptothecin Biosynthesis in Ophiorrhiza pumila
Camptothecin (CPT) is a monoterpenoid indole alkaloid produced in several plants and is a clinically important natural resource that serves as the precursor for the semi-synthetic anticancer drugs such as topotecan and irinotecan. CPT po...

Synthesis of Deuterated Cycrimine Based on Multiple Deuteration of Cycloalkane Carboxylic Acid
In recent years, deuterated pharmaceuticals (heavy drugs) have attracted significant attention as novel drug discovery modalities. While the stronger C–D bonds, as compared to C–H bonds, result in improved metabolic stability, the introd...

Efficient and Practical Synthesis of β-Naphthol-Substituted 2-Azetines via Vinylidene ortho-Quinone Methide (VQM) Intermediates
We report an efficient and practical strategy for the synthesis of bromo-substituted 2-azetines bearing a β-naphthol moiety. The reaction proceeds via the formation of highly reactive vinylidene ortho-quinone methide (VQM) intermediates,...
