Abstract
A new group of compounds, generically classed as phenothiazinyl sulfides, are described having the formula: ##STR1## wherein n is 1 or 2, x and/or y and/or z represent 0, 1 or 2; R.sub.1 may be H, alkyl, aryl, alkaryl, acyl, haloacyl and biologically activating aminoalkyl groups known in the medicinal arts, such as --(CH.sub.2).sub.3 --N(CH.sub.3).sub.2, ##STR2## and -[2-(1-methyl-2-piperidyl)ethyl]; and R.sub.2 and/or R.sub.3 and/or R.sub.4 and/or R.sub.5 and/or R.sub.6 and/or R.sub.7 represent H, OH, Cl, Br, F, CF.sub.3, SH, NO.sub.2, CN, COOH, alkyl, alkoxy, sulfamoyl, dimethylsulfamoyl, dimethyl amino, aryl, alkaryl, acyl, aryloxy, methyl sulfonyl, methyl thio, and -S-phenothiazinyl substitutents; and as charge-transfer complexes of iodine therewith in which the number of moles of iodine associated with the molecule equals 1.5 (range 0.75 to 3.0) times the number of phenothiazinyl groups in the molecule. Methods for the preparation of the compounds are described. The phenothiazinyl sulfides appear to be active in the same industrial and biological applications as phenothiazine and its corresponding derivatives, and show distinctive activity in various uses and as charge-transfer complexes of novel electrochemical properties as illustrated, in-vitro, in combination with iodine as a cathode material.
