    Substituted pyrazinecarboxamides: Synthesis and biological evaluation

  • Original language description

    Condensation of the corresponding chlorides of some substituted pyrazine-2-carboxylic acids (pyrazine-2-carboxylic acid, 6-chloropyrazine-2- carboxylic acid, 5-tertbutylpyrazine-2-carboxylic acid or 5-tert-butyl-6- chloropyrazine-2-carboxylic acid) withvarious ring-substituted aminothiazoles or anilines yielded a series of amides. The syntheses, analytical and spectroscopic data of thirty newly prepared compounds are presented. Structure-activity relationships between the chemical structures and the antimycobacterial, antifungal and photosynthesis-inhibiting activity of the evaluated compounds are discussed. 3,5-Bromo-4-hydroxyphenyl derivatives of substituted pyrazinecarboxylic acid, 16-18, have shown the highest activity against Mycobacterium tuberculosis H37Rv (54-72 % inhibition).

    Substituované pyrazinkarboxamidy: Syntéza a biologická aktivita

  • Czech description

    Kondenzace odpovídajících chloridů vybraných substituovaných pyrazin-2- karboxylových kyselin (pyrazin-2-karboxylová kyselina, 6-chloropyrazin-2-karboxylová kyselina, 5-tercbutylpyrazin-2-karboxylová kyselina či 5-terc-butyl-6-chloropyrazin-2-karboxylovákyselina) s různými substituovanými aminothiazoly či aniliny nechaly vzniknout sérii amidů. 3,5,-bromo-4-hedroxyfenyl deriváty substituované pyrazinkarboxylové kyseliny, 16-18, vykázala nejvyšší aktivitu proti Mycobacterium tuberculosis H37Rv (54-72 % inhibice). Nejsilnější antifungální účinek proti Trichophyton mentagrophytes měla sloučenina 5-terc-butyl-6-chloro-N-(4-metyl-1,3-thiazol-2-yl)pyrazin-2-karboxamid (8, MIC = 31,25 mol/ml) Nejaktivnějšími inhibitory vývoje kyslíku v chloroplastech ze špenátu byly sloučeniny 5-terc-butyl-6-chloro-N-(5-bromo-2-hydroxyfenyl)-pyrazin-2-karboxamid (27, IC50 = 41,9 mol/l) a 5-terc-butyl-6-chloro-N-(1,3-thiaziol-2-yl)-pyrazin-2-karboxamid (4, IC50 = 49,5 mol/l).
