1 Efficient, column-chromatography-free synthesis of Dipterocarpol succinate oxime ester salts / Nguyen Dang Minh Khanh, Nguyen Hoang Long, Nguyen Trong Thien, Le Quang Phong // .- 2020 .- Số 05(42) .- P. 99-105 .- 540
Natural-product-based drugs commonly were converted to organic or inorganic salts due to better stability, solubility or membrane-permeability of new salts compared to the drug itself. In this report, succinate oxime ester of dipterocarpol was synthesized successfully in a simple column chromatography-free isolation process. The oxime ester acid was then reacted with various organic, inorganic base to create different counterion salts. Two derivatives were shown to be stable for a period of time for future antimicrobial evaluation.
2 A mini review on lignin : structures, preparations, and applications = Tổng quan về lignin : cấu trúc, phương pháp tổng hợp và ứng dụng / Le Van Thuan, Tran Thi Kieu Ngan, Tran Nguyen Tien // .- 2021 .- Số 02(45) .- P. 81-86 .- 540
This work intends to provide a comprehensive overview of structures and different types of lignin, as well as the recent progress in its preparation techniques. Besides, the extensive range of applications and opportunities of lignin were also discussed in detail.
