In the last two decades, trans-sialidase of Trypanosoma cruzi (TcTS) has been an important pharmacological target for developing new anti-Chagas agents. In a continuous effort to discover new potential TcTS inhibitors, 3-amino-3-arylpropionic acid derivatives (series A) and novel phthaloyl derivatives (series B, C and D) were synthesized and molecular docking, TcTS enzyme inhibition and determination
在过去的二十年中,克氏锥虫(TcTS)的转唾液酸酶已成为开发新型抗Chagas药物的重要药理目标。为了不断发现新的潜在TcTS抑制剂,合成了3-氨基-3-芳基丙酸衍生物(系列A)和新型邻苯二甲酰基衍生物(系列B,C和D),并进行了分子对接,TcTS酶抑制和锥虫活性的测定。进行了。 在获得的四个系列中,与参考DANA(-7.8 kcal / mol)(TS酶的天然配体)相比,化合物D-11具有最高的结合亲和力值(-11.1 kcal / mol)。此外,化合物D-11的3D和2D相互作用分析显示,氢键,π-π堆积,π-阴离子,疏水和范德华力与所有重要氨基酸残基(Arg35,Arg245,Arg314,Tyr119,Trp312, TcTS的活性位点上的Tyr342,Glu230和Asp59)。此外,通过高效离子交换色谱法(HPAEC),D-11对TcTS酶的抑制作用最高(86.9%±5)。最后,在相同的裂解百分比(10μg/
