PCT No. PCT/HU81/00038 Sec. 371 Date May 7, 1982 Sec. 102(e) Date May 7, 1982 PCT Filed Sep. 11, 1981 PCT Pub. No. WO82/01001 PCT Pub. Date Apr. 1, 1982.The invention relates to new 2-hydroxymethyl-quinoxaline-1,4-dioxide derivatives of the general formula (I) (I) wherein A represents an amino group, or a group of the general formula -NH-COOR1, wherein R1 stands for a C2-4 alkyl group, or a group of the general formula -NH-CX-NH2, wherein X denotes an oxygen or sulfur atom, or a group of the formula -NH-C(NH)-NH2, or a group of the general formula -NH-R2, wherein R2 represents a C1-6 alkyl, a phenyl, a benzyl, a hydroxyl or a hydroxy-(C2-4alkyl) group, or a group of the general formula -NH-CO-R3, wherein R3 stands for a C1-20 alkyl group or a phenyl group optionally substituted by one, two or three identical or different substituent(s) selected from the group consisting of nitro, hydroxyl, amino, C1-3 alkoxy and halogen; a naphtyl group optionally substituted by a hydroxyl group, a phenyl-(C1-3 alkyl) group, a pyridyl, a piperidyl, a pyrazinyl, a pyrimidyl, a 1,2,4-triazinyl, a furyl, a nitrofuryl or an alpha , alpha -diphenyl- alpha -hydroxymethyl group. Due to their antimicrobial and weight-gain increasing effects, the new compounds of the general formula (I) can serve as active ingredients of pharmaceutical or veterinary compositions, particularly fodder concentrates, fodder additives and fodders. The invention relates also to the preparation of the new compounds of the general formula (I) and the compositions containing same.
