A method for the one-pot synthesis of phenothiazines from benzothiazoles and aryl ortho-dihalides was explored. Preliminary work on the mechanism of the reaction suggested that it follows a domino process, including the hydrolysis of benzothiazoles followed by C–S coupling and C–N coupling. The low loading of the catalyst system (5 mol-% for both copper and ligand), the mild experimental conditions

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.

Repositioning of the antipsychotic drug trifluoperazine for treatment of glioblastoma, an aggressive brain tumor, has been previously suggested. However, trifluoperazine did not increase the survival time in mice models of glioblastoma. In attempt to identify an effective trifluoperazine analog, fourteen compounds have been synthesized and biologically in vitro and in vivo assessed. Using MTT assay
