Synthesis and antitubercular activity of phenothiazines with reduced binding to dopamine and serotonin receptors
摘要:
Analogs of the psychotropic phenothiazines were synthesized and examined as antitubercular agents against Mycobacterium tuberculosis H37Rv. The compounds were subsequently counter-screened for binding to the dopaminergic-receptor subtypes D1, D2, D3 and the serotonergic-receptor subtypes 5-HT1A, 5-HT2A, and 5-HT2C. The most active compounds showed MICs from 2 to 4 mu g/mL and had overall reduced binding to the dopamine and serotonin receptors compared to chlorpromazine and trifluoperazine.

An efficient potassium carbonate-mediated tandem C–S and C–N coupling reaction between N-(2-iodophenyl)acetamides and 2-halo-benzenethiols has been developed. This protocol affords a simple and efficient approach for the construction of phenothiazine derivatives without the need for addition of transition-metal catalyst or ligand for the first time. Furthermore, the reaction can be easily performed

A convenient method for the synthesis of various substituted phenothiazines from cyclohexanones and 2-aminobenzenethiols using molecular oxygen as hydrogen acceptor in the absence of transition-metals is described. For the first time cyclohexanones were used as coupling partners for the construction of phenothiazines.

ABSTRACT An efficient cesium carbonate-mediated synthesis of phenothiazine derivatives from S-2-acetamidophenyl ethanethioates and ortho-dihaloarenes has been developed. This protocol affords an efficient approach for the construction of phenothiazine derivatives without the need of transition-metal catalyst or ligand. A plausible mechanism is proposed.
