WebDec 5, 2024 · To overcome this bottleneck in our mechanistic understanding of inhibition and aid the improvement of inhibitors by structure-based design, we have here characterized the detailed interactions between aromatic bis-isothiourea based compounds and their derivatives with human DMT1 and its prokaryotic homologue EcoDMT.
Origin of diastereoselectivity and catalytic efficiency on Isothiourea ...
WebAn isothiourea-catalyzed fluorination of alkynyl-substituted acetic acids provides a broad range of optically active tertiary α-alkyl fluorides in high enantioselectivity (up to 97% ee). Furthermore, this methodology can be scaled up to a Gram scale without loss of enantioselectivity. S. Yuan, W.-H. Zheng, J. Org. Chem., 2024, 87, 713-720. WebIsothiouronium.
