Page/Page column 39, (2018/08/20)
The present invention provides a phenothiazine derivative or a pharmaceutically acceptable salt thereof, a method of preparing a compound selected therefrom and a pharmaceutical composition containing the compound as an active ingredient. The phenothiazine derivative according to the present invention has an effect of inhibiting calmodulin (CaM; calcium-modulated protein) and thus helps cell death by maintaining the intracellular level of calcium in lung cancer cells at high concentration. Accordingly, the phenothiazine derivative according to the present invention can be usefully used to prevent or treat malignant tumors such as lung cancer.

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.

The invention develops a method for synthesizing phenothiazine compounds by using benzothiazole and derivatives thereof as well as 1-bromo-2-iodobenzene and derivatives thereof as raw materials and copper or copper salt/N-alkoxy-1H-pyrrolic amide system as a copper catalyst. The method is a brand-new method for synthesizing phenothiazine compounds. The method has the characteristics of low temperature, short reaction time, low solvent toxicity and wide substrate adaptability, and has wide application prospects in the aspect of preparation of medicines, pesticides and materials.

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 (90 °C, 12 h), and the use of a green reaction medium make this synthesis very attractive to academia and industry. A copper-catalyzed domino reaction consisting of the hydrolysis of benzothiazoles followed by C-S and C-N couplings for the synthesis of phenothiazines from benzothiazoles and aryl ortho-dihalides is described. The low loading of the catalyst system, mild experimental conditions, and the use of polyethylene glycol as the solvent make this synthetic approach very attractive to academia and industry.

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.
