A new simple and sensitive spectrophotometric method for some phenothiazine derivatives has been developed. The proposed method is based on the reaction of phenothiazine derivatives promethazine hydrochloride, chlorpromazine hydrochloride, triflupromazine hydrochloride, prochlorperazine, and trifluoperazine with potassium iodate followed by reaction of liberated iodine with leuco crystal violet (LCV) and measurement of the color of the oxidized LCV at 598 nm. The method showed a good linearity in the ranges 0.05–4.0, 0.02–2.0, 0.05–5.0, 0.1–8.0, and 0.05–2.0 µg mL−1 respectively. The optimum conditions and other analytical parameters were evaluated. The proposed methods have been applied successfully to the analysis of phenothiazine derivatives in pure form and in their dosage forms, and no interference was observed from common excipients present in pharmaceutical formulations.

The sulfoxides of pharmacologically active phenothiazinederivatives have been widely studied as biological transformation products in body fluids and tissue (1,2). The majority of the work has been devoted to the development of analytical techniques for detection of these products (2,3,4).

The present invention relates to a method for treating a subject with a cancer resistant to a chemotherapeutic drug comprising administering to said subject a therapeutically effective amount of prochlorperazine or its analog or metabolite, or a pharmaceutically acceptable salt thereof, in combination of the chemotherapeutic drug. The present invention also relates to a method for preventing cancer metastasis with the combination of prochlorperazine in combination of a chemotherapeutic drug.

A simple method is reported for the preparation of gram quantities of phenothiazine sulfoxides by aqueous nitrous acid oxidation of phenothiazines at room temperature. The chiral levomepromazine gave rise to diastereoisomeric products analogous to those reported for thioridazine sulfoxidation.
