title: [Antigenicity study of 6-amidino-2-naphthyl 4(-)[(4,5-dihydro-1H-imidazol-2-yl)amino] benzoate dimethanesulfonate (FUT-187) in guinea pigs and mice.
abstract: Antigenicity study of 6-amidino-2-naphthyl 4(-)[(4,5-dihydro-1H-imidazol-2-yl)amino] benzoate dimethanesulfonate (FUT-187), a new protease inhibitor, was investigated in guinea pigs and mice and the following results were obtained. 1. In guinea pigs immunized with FUT-187 plus adjuvant by intramuscular/subcutaneous routes, ASA, ACA and PCA reactions challenged intravenously or intradermally were positive. 2. In guinea pigs immunized with FUT-187 plus adjuvant by intramuscular/subcutaneous routes, ASA and PCA reactions challenged orally were negative. 3. In guinea pigs immunized with FUT-187 by the oral route, ASA, ACA and PCA reactions were negative. 4. In guinea pigs immunized with IABA and AN plus adjuvant by intramuscular/subcutaneous routes, ASA and PCA reactions were negative. 5. 48-hr PCA reactions were elicited with sera obtained from BALB/c and C3H/He mice immunized with FUT-187 plus adjuvant by the intraperitoneal route, responses were negative. 6. From the results of hapten inhibition tests using anti-FUT-187 guinea pig serum, it is suggested that the antigenicity of FUT-187 is attributable to the its benzoic acid.
