Thread-based platform for nitrite detection based on a modified Griess assay

Research highlight / By

A new thread-based platform was developed for colorimetric detection of nitrite based on a modified Griess assay. Cellulose thread was functionalized with a p-aminobenzoyl group and impregnated with chromotropic acid as a coupling reagent. The reactions including diazotization and coupling reaction occurred along the length of the thread and a pink colored band was produced …

Facile and green synthesis of pullulan derivative-stabilized Au nanoparticles as drug carriers for enhancing anticancer activity

Research highlight / By

In this work, we report for the first time AuNPs reduced/stabilized/capped with modified para-aminobenzoic acid-quat188-pullulan (PABA-QP) as excellent nanocarriers for delivery of doxorubicin to enhance the activity and safety of these systems. Spherical AuNPs@PABA-QP obtained by facile and green synthesis under optimum conditions were characterized by UV-VIS, TEM, EDS, SAED, XRD, ATR-FTIR and zeta-potential analyses …

Two new rearranged clerodane diterpenes from Thai Tinospora baenzigeri

Research highlight / By

A new rearranged clerodane-type diterpene (1), tinobaenzigeride, and a new rearranged clerodane glucoside (2) were isolated from the stems of Tinospora baenzigeri, along with four known compounds (3‒6). Their structures were elucidated by spectroscopic data analysis. In addition, the structure and configuration of 1 was confirmed by single-crystal X-ray diffraction analysis. Compound 1 are a …
