Abstract We recently reported the synthesis, of a potent papain-family cathepsin L-like cysteine protease inhibitor, as new lead compound for the development of new drugs that can be used as antiprotozoal agents. The investigation of its conformational profile is crucial for the in-depth understanding of its biological behaviour. Our careful NMR analysis has been based on the complete and total assignment
摘要 我们最近报道了一种有效的木瓜蛋白酶家族组织蛋白酶 L 样半胱氨酸蛋白酶抑制剂的合成,作为开发可用作抗原虫药物的新药物的新先导化合物。对其构象特征的研究对于深入了解其生物学行为至关重要。我们仔细的 NMR 分析基于 CDCl3 和 CD3OH 中分子的 1H、13C、15N 和 19F 信号的完整和全部分配,这可以以某种方式将极性相和非极性相重现到生物环境中。通过这种方式,揭示了分子在极性和非极性介质中的不同行为。在CDCl3中,可以根据通过空间接触检测到的情况来定义稳定的构象排列,而,
