dc.description.abstractNeurodegenerative diseases are disorders related to the degeneration of central neurons that gradually lead to various, severe alterations of cognitive and/or motor functions. Currently, for no such diseases does any pharmacological treatment exist able to arrest its progression. Riluzole (1) is a small molecule able to interfere with multiple cellular and molecular mechanisms of neurodegeneration, and is the only approved treatment of amyotrophic lateral sclerosis (ALS), the progression of which proved to significantly slow, thus increasing somewhat average survival. Here we report the synthesis of differently functionalized 4H-3,1-benzothiazine (5–6) and 2H-1,4-benzothiazine (7) series as superior homologues of 1. Biological evaluation demonstrated that amidine 4H-3,1-benzothiazine derivatives 5b-d can reduce glutamate and LDH release in the oxygen/glucose deprivation and reperfusion model (OGD/R) applied to brain slices with a higher potency than 1. Moreover the mentioned compounds significantly reduce glutamate- and 6-hydroxydopamine (6-OHDA)-induced cytotoxicity in neuroblastoma cells. In addition, the same compounds limit ROS formation in both neuronal preparations. Finally, 5c proved effective in inhibiting neuronal voltage-dependent Na+ and Ca2+-channels, showing a profile comparable with that of 1.
