  摘要：

  The 2-[3-( substituted-amino)-2hydroxypropyl]-4,6-dimethyl-3-oxo-2,3-dihydroisothiazo[5,4-b]pyridines 3 were synthesized and pharmacologically evaluated in animal models. The preliminary pharmacological screening study showed that the investigated compounds were toxic and had no significant activity in central nervous system (CNS) tests. Additionally, compounds 3, and several other 2-substituted-4,6-dimethyl-3-oxo-2,3-dihydroisothiazol described here (2), together with those (4) reported in a previous paper, were evaluated in vitro against Mycobacterium tuberculosis H37Rv. For comparison, products of the rearrangement of some isothiazolopyridine 1,1-dioxides (4a,b) with the corresponding pyrido[3,2-e]-1,2-thiazines (5a,b) and different N-2-substituted derivatives of the latter (5c-i) were also prepared and investigated in antimycobacterial tests. The most potent antituberculars of the 23 compounds assayed are 2-[3-(4-benzylpiperidin-1 -yl)-2-hydroxypropyl]-4,6-dimethyl-3-oxo-2,3-dihydroisothiazolo [5,4-b]pyridine 3d and ethyl (4,6-dimethyl-3-oxo-2,3-dihydroisothiazolo[5,4-b]pyridin-2-yl)acetate 4c (MIC < 12.5 mu g/ml, 100 and 98% inhibition, respectively).
