Various 2-aminothiazoles (2a-s and 3a-g) and 2-thiazolecarboxamides (4a-h), possessing a nitrogeneous basic moiety at the C-2 position of the thiazole ring, were prepared and tested for anti-anoxic (AA) activity in mice.Among them, N-4-(3-trifluoromethylphenyl)-2-thiazolecarbaxamide hydrochloride (4e, FR108143) (minimum effective doses of 3,2 mg/kg i.p. and 10 mg/kg p.o., respectively) exhibited more potent AA activity than either FK360 or compound 1, each of which has a nitrogeneous basic moiety at the C-5 position.The structure-activity relationship with regard to AA activity of this series of compounds are discussed, and the three-dimensional electrostatic potentials (3D-MEP) around the basic nitrogen atom of FK360 and the thiazole derivative (4e) are compared.Key words cerebral protective agent; anti-anoxia; 2-aminothiazole; 2-thiazolecarboxamide; structure-activity relationship; FK360
