    Abstract: PROBLEM TO BE SOLVED: To obtain an oxopyrrolopyrrole derivative comprising a specific oxopyrrolopyrrole derivative and useful as a medicine for preventing and treating a decease caused by thrombin-induced platelet aggregation or thrombin- induced aggregation of fibrinogen in blood plasma. SOLUTION: This oxopyrrolopyrrole derivative is the new one (a hydrate or a salt) of formula I [R is a lower alkyl, a cycloalkyl or phenyl; R is H, OH or a group of the formula C(O)O-A (A is a lower alkyl, a cycloalkyl or phenyl); R to R are each methyl, or R is H, and R and R form trimethylene by bonding each other] and useful as a medicine, etc., for preventing and treating a decease caused by thrombin-induced platelet aggregation or thrombin- induced aggregation of fibrinogen in blood plasma. The compound is obtained by reacting a bromo derivative of formula II with CuCN in DMF by heating to form a nitrile of formula III, reacting the nitrile with HCl in methanol and thereafter reacting the resultant product with ammonia.

    Abstract: Octahydro-1,3-dioxo-pyrrolo(3,4-c)pyrrole derivs. of formula (I), and hydrates, solvates and salts of (I), are new. R1, R2 = T (opt. substd. by Ar, Het, Cy, CONH2 or COOT), H, Ar, Het or Cy; or R2 may also be lower alkanoyl; R3 = H, COOH, CONH2, COOT, CONHT or CONT2; R4-R6 = H, T, Ar, aralkyl or Cy; or R4 and/or one of R5 and R6 is Het or T (substd. by OH, SO2H, SO3H, guanidino, aryl-lower alkyloxy, TO or TS); or R2+R4 = a tri- or tetramethylene gp. in which (a) one of the methylene gps. is opt. replaced by S, SO or SO2, or opt. substd. by OH, T, lower alkenyl or COOT, or (b) one of the methylene gps. is opt. substd. by lower alkenyl and another is opt. substd. by lower alkyl-COOH; at least one of R1-R6 is a gp. substd. by amino, amidino, guanidino or N-hydroxyamidino; T = lower alkyl; Ar = aryl; Het = heteroaryl; Cy = cycloalkyl.
