The designed aromatic amide discotic molecule with sulfonic acid groups at its periphery exhibits a hexagonal supramolecular columnar liquid crystalline phase, which leads to the achievement of anisotropic ionic conductivity through macroscopically aligning the ionic channels.
Time-resolved EPR spectra of UV-irradiated Nafion reveal the formation of spin-polarized excited triplet states and allow the detection of photoinduced triplet-triplet energy transfer processes through hydrogen bonds between water and sulfonic acid groups.
A new sulfur-containing guanidino derivative, halichondria sulfonic acid (1) showing anti-HIV-1 activity, and halistanol trisulfate (2) with anti-tumor activity have been isolated from the marine sponge Halichondria rugosa Ridley & Dendy collected in the Chinese Southern Sea. The structure of 1 was elucidated by analysis of spectroscopic and crystal data.
An expeditious synthesis of taurine derivatives though a key unprecedented organocatalyzed enantioselective sulfa-Michael addition bisulfite onto nitrostyrenes.
Abstract Pain is a complex physiological and psychological activity, involving at least three dimensions, including pain sensation, emotion, cognition. Acupuncture can clearly relieve the sensation of patients improve emotion cognition induced by pain; acupuncture participates in multi-dimensional regulation through brain regions limbic system such as anterior cingulate cortex (ACC), amygdala (...
The reaction of 3-mercaptopropylsilica (MPS) and chlorosulfonic acid in chloroform afforded silica bonded S-sulfonic acid (SBSSA), which was used as a catalyst for the room temperature synthesis of quinoxaline derivatives from 1,2-diamino compounds and 1,2-dicarbonyl compounds. The catalyst could be recycled and reused several times without any loss of efficiency.
