TRPV1 receptor is an important analgesia target. Its antagonists are expected to prevent pain perception by blocking the receptor directly. In this letter, eight dihydroisoquinoline-2(1H)-carbothioamide derivatives were designed and synthesized as TRPV1 antagonists. The benzene ring was modified with different substitutional groups. Preliminary biological tests suggested that the new compounds exhibited TRPV1 antagonist activity and different analgesia effects, some of which were promising as analgesia drugs.

isothiocyanates antifungicidal activity is following: p-nitrophenyl > p-methoxyphenyl > p-chlorophenyl > p-methylphenyl > p-ethylphenyl > phenyl > p-fluorophenyl. For antibacterial activity, the order was p-nitrophenyl > p-chlorophenyl > p-methylphenyl > p-ethylphenyl > p-fluorophenyl > phenyl > p-methoxyphenyl. The present study indicates that some of the compounds exhibit promising antimicrobial activity and

A facile and general protocol for the preparation of isothiocyanates from alkyl and arylamines is reported. This method relies on a tosyl chloride mediated decomposition of a dithiocarbamate salt that is generated in situ by treatment of an amine with carbondisulfide and triethylamine. Utilizing this protocol, we have prepared 19-alkyl- and arylisothiocyanates in moderate to excellent yield.
Abstract A number of alkyl, aryl and bifunctional isothiocyanates are obtained in moderate to high yields (41–94%) in a two-step, one-pot reaction of the parent primary amines or their salts with carbondisulfide, followed by reaction of the thus formed dithiocarbamates with T3P® (propane phosphonic acid anhydride) as a new and efficient desulfurating agent. A number of alkyl, aryl and bifunctional isothiocyanates
