we have reported anti-TB properties of a new class of conformationally-constrained indeno[2,1-c]quinolines, which are although considerably active (MIC 0.39–0.78 μg/mL) suffered from intense solubility problems. We thought of improving their bioavailability by prodrugs approach. Accordingly esters of the “Lead” indeno[2,1-c]quinolines 1, 15 and 27 derivatives were synthesized and their prodrug nature
最近,我们报道了一类新的构象受限的茚并[ 2,1 - c ]喹啉类药物的抗结核特性,尽管它们的活性相当大(MIC 0.39–0.78μg/ mL),但存在严重的溶解性问题。我们考虑通过前药方法提高其生物利用度。“先驱”茚并因此酯[2,1- c ^ ]喹啉1,15周27的衍生物的合成和在生理pH下它们的前体药物的性质得到了证实。评价前药对结核分枝杆菌的抗分枝杆菌活性通过MABA测定的H37Rv表明,与它们各自的母体化合物相比,它们的抗结核病活性提高了2至4倍,水溶性增加,选择性指数更高。这些前药的MIC在<0.20–6.0μg/ mL的范围内,通常在VERO细胞中未观察到细胞毒性。
