new pyrazolo[3,4‐d]thiazoles for the development of molecules with a high therapeutic potential. The effective and appropriate strategy chosen consists of an intramolecular copper‐catalysed N‐arylation followed by the Liebeskind‐Srogl cross‐coupling reaction. The efficiency of copper and palladium catalysts for the first step of the synthesis was evaluated. These efforts allowed the synthesis of a

The in vitro growth inhibitory activity of 26 thiazoles (including 4-halogeno-2,5-disubtituted-1,3-thiazoles) and 5 thienothiazoles was assessed on a panel of 6 human cancer cell lines, including glioma cell lines. (4-Chloro-2-(piperidin-1-yl)thiazol-5-yl)(phenyl)methanone (12a) and (4-bromo-2-(piperidin-1-yl)thiazol-5-yl)(phenyl)methanone (12b) displayed similar to 10 times greater in vitro growth inhibitory activity than perillyl alcohol (POH), which therapeutically benefits glioma patients through the inhibition of both alpha-1 Na+/K+-ATPase (NAK) and Ras oncogene activity. The in vitro cytostatic activities (as revealed by quantitative videomicroscopy) displayed by 12a and 12b were independent of the intrinsic resistance to pro-apoptotic stimuli associated with cancer cells. Compounds 12a and 12b displayed relatively similar inhibitory activities on purified guinea pig brain preparations that mainly express NAK alpha-2 and alpha-3 subunits, whereas only compound 12b was efficacious against purified guinea pig kidney preparations that mainly express the NAK alpha-1 subunit, which is also expressed in gliomas, melanomas and non-small-cell lung cancers NSCLCs.
