Page/Page column 12, (2015/12/17)
The present invention relates to pharmaceutical compositions and methods for controlling tumor growth in cancer patients. These compounds and pharmaceutical compositions modulate the P-glycoprotein multidrug transporter system and inhibit the activated PI3K/Akt/mTOR/p70S6K signaling pathway. The compounds and pharmaceutical compounds of the present invention are particularly useful for treating metastatic and drug-resistant tumors.

Preparation of 2-alkylthio-phenothiazines by direct functionalization of phenothiazine by reaction of the phenothiazine, N-protected by an acryl group, with a sulfonating agent such as sulfuric acid, sulfuric anhydride, chlorosulfonic acid, or oleum, in order to obtain, after work-up of the reaction mixture, phenothiazine-2-sulfonic acid, followed by the reduction of this or, optionally, of its acyl chloride derivative, to obtain 2-mercapto-phenothiazine which subsequently is subjected to S-alkylation to thereby obtain the desired target compound.

A process for the direct and regioselective functionalization of phenothiazine which allows to introduce an SH group in position 2 is described. The thus obtained 2-mercapto-phenothiazine is easy transformed into 2-methylthio-phenothiazine, an important intermediate for the preparation of pharmacological active compounds.
