  Synthesis and Biological Evaluation of Amidine, Guanidine, and Thiourea Derivatives of 2-Amino(6-trifluoromethoxy)benzothiazole as Neuroprotective Agents Potentially Useful in Brain Diseases

  摘要：

  A series of amidine, thiourea, and guanidine derivatives of 2-amino-6-(trifluoromethoxy)benzothiazole termed 2, 3, and 4, respectively, and structurally related to riluzole, a neuroprotective drug in many animal models of brain disease, have been synthesized. The biological activity of compounds 2a-e, 3a-f, and 4a,b was preliminarily tested by means of an in vitro protocol of ischemia/reperfusion injury. The results demonstrated that 2c and 3a-d significantly attenuated neuronal injury. Selected for testing of their antioxidant properties, compounds 3a-d were shown to be endowed with a direct ROS scavenging activity. Compounds 3b and 3d were also evaluated for their activity on voltage-dependent Na(+) and Ca(2+) currents in neurons from rat piriform cortex. At 50 mu M, compound 3b inhibited the transient Na(+) Current to a much smaller extent than riluzole, whereas 3d was almost completely ineffective.
