    摘要: NOVEL COMPOUNDS USEFUL AS CHEMO-THERAPEUTIC AGENTS BECAUSE FO THEIR OUTSTANDING EFFCTIVENESS AGAINST A WIDE RANGE OF MICRO-ORGANISMS, SUCH AS, STAPHYLOCOCCUS AUREUS, ESCHERICHIA COLI, PROTEUS MIRABILIS, PSEUDOMONAS AERUGIONOSA AND STREPTOCOCCUS PYOGENES ARE DISCLOSED. THE COMPOUNDS ARE 5 - NITROFURYL - 2-S-TRIAZOLE-(4.3-A) PYRIDINE DERIVATIVES HAVING THE FOLLOWING STRUCTURAL FORMULA:

    R2-,3-R1-S-TRIAZOLO(4,3-A)PYRIDINE

    WHEREIN R1 AND R2 ARE EACH MEMBERS SELECTED FROM THE GROUP CONSITING OF HYDROGEN, HALOGEN, ALKYL, ALKOXY, NITRO, ANIMO, ACYLAMINO, CARBOXYALKYL, CARBOXAMIDO, HYDROXYMETHYL, O-ACYLATED HYDROXYMETHYL, O-ALKYLATED HYDROXYMETHYL AND

    (2-O2N-FURAN-5-YL)-(CH=CH)N-

    WHEREIN N IS 0 OR 1, WITH AT LEAST ONE OF SAID R1 AND R2 ALWAYS BEING

    (2-O2N-FURAN-5-YL)-(CH=CH)
