    摘要: Nitroimidazolyl-s-triazolo(4,3-b)pyridazines of the formula:
    wherein R1 and R2 are, individually, hydrogen or a numbe organic radicals or, taken together, can be an alkylene bridge; AND R3 is hydrogen or lower alkyl; or, together with R2, R3 can form an alkylene bridge; N IS 0 OR 1; AND THE PHARMACEUTICALLY COMPATIBLE THEREOF, POSSESS HIGH IN VIVO EFFECTIVENESS AS ANTIMICROBIALS.

    WHEREIN R is hydrogen or lower alkyl optionally substituted in the 2position by hydroxyl or by lower acyloxy or lower alkoxy; A is hydrogen, halogen, azido, cyano; lower alkyl, alkoxy, alkylthio, alkylsulfonyl, carboxyl; lower alkoxycarbonyl, lower alkoxycarbonimidoyl; or hydrazino, carbamoyl, amidino or a carboximidohydrazide group optionally substituted by one or two lower acyl, alkyl or cycloalkyl radicals; or A is a radical of the formula:
