A series of 2‐ and 7‐substituted phthalazinones was synthesised and their potential as anti‐tubercular drugs assessed via Mycobacterium tuberculosis (mc26230) growth inhibition assays. All phthalazinones tested showed growth inhibitory activity (MIC <100 μm), and those compounds containing lipophilic and electron‐withdrawing groups generally exhibited better anti‐tubercular activity. Several lead compounds
合成了一系列2和7位取代的邻苯二氮酮,并通过结核分枝杆菌(mc 2 6230)生长抑制试验评估了它们作为抗结核药的潜力。所有测试的phthalazinones显示生长抑制活性(MIC <100μ米),以及包含亲脂性和吸电子基团的那些化合物通常具有更好的抗结核活性。几个先导化合物进行了鉴定,其中包括7 - ((2-氨基-6-(4-氟苯基)嘧啶-4-基)氨基)-2- heptylphthalazin-1(2 ħ) -酮(MIC = 1.6μ米), 4- tertbutylphthalazin-2(1 ħ) -酮(MIC = 3μ米),和7-硝基酞嗪-1(2 ħ) -酮(MIC = 3μ米)。作用方式研究表明,选定的嘧啶基-酞菁酮可能会干扰NADH氧化,但是,铅化合物的作用方式与该酶无关。MIC =最小抑制浓度。
