In excitable cells, mitochondria play a key role in the regulation of the cytosolic Ca2+ levels. A dysregulation of the mitochondrial Ca2+ buffering machinery derives in serious pathologies, where neurodegenerative diseases highlight. Since the mitochondrial Na+/Ca2+ exchanger (NCLX) is the principal efflux pathway of Ca2+ to the cytosol, drugs capable of blocking NCLX have been proposed to act as neuroprotectants in neuronal damage scenarios exacerbated by Ca2+ overload. In our search of optimized NCLX blockers with augmented drug-likeness, we herein describe the synthesis and pharmacological characterization of new benzothiazepines analogues to the first-in-class NCLX blocker CGP37157 and its further derivative ITH12575, synthesized by our research group. As a result, we found two new compounds with an increased neuroprotective activity, neuronal Ca2+ regulatory activity and improved drug-likeness and pharmacokinetic properties, such as clog p or brain permeability, measured by PAMPA experiments.

The three isomeric pivaloylaminopyridines were lithiated in more than 80% yields. Aminopyridine derivatives were treated by 2.5-3 equivalents of the complex BuLi-TMEDA at -10° in diethyl ether. Reaction of the lithiated species with various electrophiles afforded a number of ortho-substituted pivaloylaminopyridines in good yields. Secondary pyridine alcohols were oxidized to the corresponding aminopyridyl ketones. Pyridopyrimidines, benzonaphthyridines as well as an analogue of the natural antitumor alkaloid ellipticine has been synthesized showing the versatility of the method.
