Chemical and Pharmaceutical Bulletin
The Pharmaceutical Society of Japan, established in 1880, is one of Japan’s oldest and most distinguished academic societies. The Society currently has around 18,000 members. It publishes three monthly scientific journals. Chemical and Pharmaceutical Bulletin (Chem. Pharm. Bull.) began publication in 1953 as Pharmaceutical Bulletin. It covers chemistry fields in the pharmaceutical and health sciences. Biological and Pharmaceutical Bulletin (Biol. Pharm. Bull.) began publication in 1978 as the Journal of Pharmacobio-Dynamics. It covers various biological topics in the pharmaceutical and health sciences. A fourth Society journal, the Journal of Health Science, was merged with Biol. Pharm. Bull. in 2012. Yakugaku Zasshi (Japanese for “Pharmaceutical Science Journal”) has the longest history, with publication beginning in 1881. Yakugaku Zasshi is published mostly in Japanese, except for some articles related to clinical pharmacy and pharmaceutical education, which are published in English.
The main aim of the Society’s journals is to advance the pharmaceutical sciences with research reports, information exchange, and high-quality discussion. The average review time for articles submitted to the journals is around one month for first decision. The complete texts of all of the Society’s journals can be freely accessed through J-STAGE. The Society’s editorial committee hopes that the content of its journals will be useful to your research, and also invites you to submit your own work to the journals.

Structural Development of Cell-Penetrating Peptides Containing Cationic Proline Derivatives Read more
Editor’s picks

The authors designed and synthesized a series of cell-penetrating peptides containing cationic proline derivatives (ProGu) that exhibited responsive changes in their secondary structures to the cellular environment. Effects of the peptide length and steric arrangement of the side chain in cationic proline derivatives [Pro4SGu and Pro4RGu] on their secondary structures and cell membrane permeability were investigated. Moreover, peptides 3 and 8 exhibited efficient intracellular delivery of plasmid DNA. These results indicate that the peptides containing cationic proline derivatives could be a useful tool to deliver the hydrophilic biomolecules into the cells.

Palladium-Catalyzed External-CO-Free Carbonylation of Aryl Bromides Using 2,4,6-Trichlorophenyl Formate Read more
Editor’s picks

A practical Pd-catalyzed carbonylation of (hetero)aryl bromides using a crystalline carbon monoxide (CO) surrogate, 2,4,6-trichlorophenyl formate (TCPF), was developed. This reaction proceeds without the slow addition technique that was previously required and with a low catalyst loading (1 mol%) on a gram scale. The utility of this Pd-catalyzed external-CO-free carbonylation using TCPF was demonstrated in the synthesis of a histone deacetylase inhibitor.

Scale-Up of Lubricant Mixing Process by Using V-Type Blender Based on Discrete Element Method Read more
Editor’s picks

In this study, scale-up experiments of the lubricant mixing processes were conducted for V-type blenders under the same condition of fill level and Froude number. Three scales of V-type blender were used for the scale-up experiment. However, the physical properties of them were not corresponded either mixing time or number of revolution. Thus, the DEM simulations of three scales of V-type blender mixing were conducted to find the scale-up factor. As a result, it was found that a scale-up simulation based on the travel distance of particles is valid for lubricant mixing scale-up processes.

Identification and Quantification of Alkaloid in KHR98 and Fragmentation Pathways in HPLC-Q-TOF-MS Read more
Editor’s picks

The authors established a HPLC-Q-TOF-MS method for rapid analysis of alkaloids in KHR98 (the extract of Uncaria rhynchophylla). A total of eight compounds, including four known alkaloids and four unknown components, were detected and identified. The structural information and fragmentation pathways of eight components were interpreted. A precise and sensitive HPLC-MS method was validated to simultaneously determine these substances. This study shed light on the standardization and quality control of the KHR98 and provided a foundation for the further research on pharmacology, follow-up clinical research and New Drug Applications.
