X¹ and Y¹, which may be the same or different, represent CH or N;
X² represents CH or, when X¹ represents CH, may also represent N;
Y² represents N or, when Y¹ represents N, may also represent CH;
Z represents N or N⁺R⁵;
R¹ represents a hydrogen atom or a hydroxyl, C₁₋₄alkyl or 2,2,2- trifluoroethyl group;
R² represents a hydrogen atom or, when both X¹ and X² represent CH, may also represent a fluorine, chlorine or bromine atom or a C₁₋₄alkyl group;
R³ represents a hydrogen atom or, when both Y¹ and Y² represent N, may also represent a C₁₋₄alkyl or hydroxymethyl group.
R⁴ represents a hydrogen atom or , when Z represents N, R⁴ may also represent a C₁₋₄alkyl group;
R⁵ represents a C₁₋₄alkyl or phenylC₁₋₄alkyl group;
R⁶ represents a hydrogen atom or a C₁₋₄alkyl group.
The compounds inhibit fibrinogen - dependent blood platelet aggregation.
