synthesized. To reduce the lipophilicity of Q203 caused by linearly extended side chains, shorter and heteroatoms containing fused rings were introduced into the side chain region. Antitubercular activity was tested against H37Rv-GFP replicating in liquid broth culture medium (extracellular) and within macrophages (intracellular). Many analogues showed potent extracellular activities as well as intracellular
设计并合成了一组新型抗结核药Q203的稠合环类似物。为了降低由线性延伸的侧链引起的Q203的亲脂性,将较短且含杂原子的稠环引入侧链区域。测试了抗H37Rv-GFP在液体肉汤
培养基(细胞外)和巨噬细胞(细胞内)中复制的抗结核活性。许多类似物显示出有效的细胞外活性以及细胞内活性,而没有细胞毒性。其中,化合物18-21显示出显着的抗结核活性,并具有良好的代谢稳定性。代表性化合物21表现出优异的体内 在血浆中高药物暴露
水平下的药代动力学值,使该化合物成为新的抗结核药物的有希望的候选者。
