reports the synthesis, chromatographic separation, and pharmacological evaluation of the two enantiomers of a new compound, named Retro-2.1, active against toxins by inhibiting intracellular trafficking via the retrograde route. The absolute configuration of the bioactive enantiomer has been assigned from X-ray diffraction to the (S)-enantiomer. To date, (S)-Retro-2.1 is the most potent molecule to
本研究报告了一种名为 Retro-2.1 的新化合物的两种对映异构体的合成、色谱分离和药理学评估,该化合物通过抑制逆行途径的细胞内运输来对抗毒素。生物活性对映体的绝对构型已从 X 射线衍射指定为 ( S )-对映体。迄今为止,( S )-Retro-2.1 是抵消蓖麻毒素和志贺毒素潜在细胞毒性的最有效分子,EC50 值分别为 23 和 54 nM。
