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.

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.
