A Mild Photocatalytic Synthesis of Guanidine from Thiourea under Visible Light

Guanidine has been known as an important building blocks for pharmaceutical and chemical industry, due to their broad spectrum of bioactivities. However, the synthesis of guanidine requires stoichiometric amounts of desulfurizing agents leading to toxic extra waste generation. Herein, we reported the first catalytic guanylation process which can be performed at room temperature in a …

Feeding Cells with a Novel “Trojan” Carrier: Citrate Nanoparticles

In this work, the preparation of novel calcium citrate (CaCit) nanoparticles (NPs) has been disclosed and the use of these NPs as “Trojan” carriers has been demonstrated. The concentration ratio between calcium ions and citrate ions was optimized, yielding spherical NPs with size in the range of 100–200 nm. Additionally, a fluorescent dye, fluorescein isothiocyanate …

Synthesis, characterization, and hole-transporting properties of benzotriazatruxene derivatives

Hole-transport is an important process in electronic devices such as organic field-effect transistors (OFETs) and organic light-emitting diodes (OLEDs). However, the molecular structures required for hole-transporting materials in OFET and OLED applications are quite different. In this paper, we examined the effect of alkylation onto a disk-like shaped molecule both in OFET and OLED devices. …

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

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

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

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 …
