摘要

5-Quinoxalyl -imidazolidin-2,4-diones of formula (I) and their physiologically acceptable salts are new: the quinoxaline gp. is bonded via any C atom; R1 and R2 = H, 1-6C alkyl, 5-7C cycloalkyl, phenyl- or naphthyl-(1-4C) alkyl, 6-12C aryl, 5-6 membered heterocycle contg. S, O or 1-2 N (opt. benzo-fused), 1-4C alkoxy, halo, 1-4C haloalkyl, NO2, amino or OH; R3 and R4 are as R1 other than 1-4C alkoxy, halo or 1-4C haloalkyl; R5 = H, 1-4C alkyl, 5-7C cycloalkyl, phenyl- or naphthyl-(1-4C) alkyl or 6-12C aryl; R3 and R5, or R4 and R5, when ring A is substd., can together be (CH2)n, opt. substd. by 1-4C alkyl, or R3 and R4 are together, when ring B is substd., (CH2)m, opt. substd. by 1-4C alkyl; n = 2-4; m = 3-5.
