better bio-availability and as more efficient transport forms through the mycobacterial cell membranes due to the higher lipophilicity. The experimental and calculated lipophilicity, stability, antituberculotic activity, cytotoxicity as well as the quantitative structure–activity relationships (QSARs) explored by the Intelligent Problem Solver (IPS) in Trajan Neural Network Simulator 6.0 are presented
制备了一系列新的30种N-保护的氨基酸酯,作为不断寻找新的抗结核活性水杨酰苯胺的一部分。酯具有高抵抗体外活性的结核分枝杆菌,鸟分枝杆菌,以及两种菌株堪萨斯分枝杆菌,其中一个是患者的分离株,所有测试菌株的MIC范围为1–32μmol/ L。所制备的酯可以被认为是具有更高生物利用度的前药,并且由于更高的亲脂性被认为是更有效的通过分枝杆菌细胞膜的转运形式。介绍了通过Trajan神经网络模拟器6.0中的智能问题解决器(IPS)探索的实验和计算的亲脂性,稳定性,抗结核活性,细胞毒性以及定量构效关系(QSAR)。
