reaction of azoloannulated [1,2,4,5]tetrazines with guanidine was studied. New 3-guanidinoimidazo[1,2-b]- and 6-guanidino[1,2,4]triazolo[4,3-b] [1,2,4,5]tetrazines were synthesized using the nucleophilic substitution methodology. Compounds with high antibacterial and antiglycation activity were revealed.

tuberculosis strains urge the need to develop anti-TB drugs with a novel mechanism of action. We describe synthesis of 22 novel imidazo[1,2-b][1,2,4,5]tetrazine derivatives with different substituents at C(3) and C(6) positions, and their antimycobacterialactivity in vitro. 8 compounds show activity as potential serine/threonine protein kinase (STPK) inhibitors in M. smegmatis aphVIII+ test-system, which
结核病(TB)最近已成为传染病中的主要杀手。具有多种药物和广泛耐药性的结核分枝杆菌菌株促使人们需要开发具有新颖作用机制的抗结核药物。我们描述了22种新型咪唑并[1,2- b ] [1,2,4,5]四嗪衍生物的合成,这些衍生物在C(3)和C(6)位置具有不同的取代基,并在体外具有抗分枝杆菌活性。8种化合物在耻垢分枝杆菌aphVIII +测试系统中显示出作为潜在的丝氨酸/苏氨酸蛋白激酶(STPK)抑制剂的活性,这是此类的特征。5种活性最高的STPK抑制剂中的3种化合物对结核分枝杆菌H37Rv具有显着的最小抑菌浓度1微克/毫升。我们能够获得对4种化合物有抗药性的耻垢分枝杆菌mc2 155突变体,并表明它们与其他药物没有交叉耐药性,但在这4种咪唑并[1,2- b ] [1,2]中具有共同的耐药机制。,4,5]四嗪。化合物3h似乎是最有前途的,结合了预期的STPK抑制剂活性,结核分枝杆菌的最低MIC和耐药突变体出现的频率较低。

A number of new 3-substituted imidazo[1,2-b][1,2,4,5]tetrazines containing azolyl, aminopyridyl, and alkoxyl substituents was synthesized. These compounds were studied for the biological activity against mycelial anthropophilic and zoophilous dermatophyte fungi (Trichophyton, Microsporum and Epidermophyton), causing diseases of skin and its appendages (hair, nails), and yeast-like fungi Candida.
