  摘要：

  A series of 2-substituted isothiazolo[5,4-b]pyridine-3(2H)-thiones isothiazolo[5,4-b]pyridin-3(2H)-ones, N-substituted 2-sulfanylnicotinamides and the corresponding carbothioamide derivatives were synthesized and evaluated for their antimicrobial activity against several strains of Gram + and Gram - bacteria and fungi. Chemical syntheses were resumed into a comprehensive cyclic route that enables the reversible conversion for each derivative of the series considered. Among the tested compounds the N-(aralkyl)-2-sulfanylnicotinamides show the highest fungitoxicity (MIC = 1.25-5 mug/ml). The best activity towards Gram-positive bacteria was in the range of 2.5-5 mug/ml. Activity against Gram-negative bacteria was generally very poor for all compounds. (C) 2000 Elsevier Science S.A.

  3H-1,2-Dithiolo[3,4-b]pyridine-3-thione (10) reacts with primary alkylamines to give 1,2-dihydro-2-thioxo-3-pyridinecarbothioamides 11a-g and two minor products. Isothiazolo[5,4-b]pyridine-3(2H)-thiones 12a-g and 3-imino-3H-1,2-dithiolo[3,4-b]pyridines 13a-g were isolated and characterized. Further investigations allowed the synthesis of 12 and 13 in good yield.
