    生物催化动态动力学拆分立体选择性合成β-支链芳香α-氨基酸**
    摘要:
    β-支链非经典氨基酸是现代药物开发工作中有价值的分子。然而,由于需要以立体选择性方式设置多个立体中心,它们的制备仍然具有挑战性,而现代合成此类化合物的方法通常依赖于使用带有设计配体的稀有过渡金属催化剂。在此,我们报道了一种高度非对映选择性和对映选择性的生物催化氨基转移方法,可制备多种芳香族 β-支链 α-氨基酸。机理研究表明,转化通过最佳酶独有的动态动力学分辨率进行。为了突出其实用性和实用性,该生物催化反应被应用于几种 sp 3的合成富环状片段和第一次全合成jomthonic acid A。

    Four new aza-analogues of hormaomycin 1, a secondary metabolite with interesting biological activities produced by Streptomyces griseoflavus, were synthesized and subjected to preliminary tests of their antibiotic activity to provide new insights into the structure-activity relationship studies of this class of compounds. The solution structures of hormaomycin 1 and its aza-analogue 2 a were determined

  • Opiate Aromatic Pharmacophore Structure−Activity Relationships in CTAP Analogues Determined by Topographical Bias, Two-Dimensional NMR, and Biological Activity Assays
    作者:G. Gregg Bonner、Peg Davis、Dagmar Stropova、Sidney Edsall、Henry I. Yamamura、Frank Porreca、Victor J. Hruby
    DOI:10.1021/jm9900218
    日期:2000.2.1
    Topographically constrained analogues of the highly mu-opioid-receptor-selective antagonist CTAP (H-D-Phe-c[Cys-Tyr-D-Trp-Arg-Thr-Pen]-Thr-NH2, 1) were prepared by solid-phase peptide synthesis. Replacement of the D-Phe residue with conformationally biased beta-methyl derivatives of phenylalanine or tryptophan (2R,3R; 2R,3S; 2S,3R; 2S,3S) yielded peptides that displayed widely varying types of biological activities. In an effort to correlate the observed biological activities of these analogues with their structures, two-dimensional H-1 NMR and molecular modeling was performed. Unlike the parent (1), which is essentially a pure mu antagonist with weak delta agonist activities in the MVD bioassay, the diastereomeric beta-MePhe(1)-containing peptides exhibited simultaneous delta agonism and mu antagonism by the (2R,3R)-containing isomer 2; mu antagonism by the (2R,3S)-containing isomer 3; weak mu agonism by the (2S,3R)-containing isomer 4; and delta agonism by the (2S,3S)-containing isomer 5. Incorporation of beta-MeTrp isomers into position 1 led to peptides that were mu antagonists (2R,3R), 8; (2R,3S), 9, or essentially inactive (<10%) in the MVD and GPI assays (2S,3R), 10; (2S,3S), 11. Interestingly, in vivo antinociceptive activity was predicted by neither MVD nor GPI bioactivity. When D-Trp was incorporated in position 1, the result (7) is a partial, yet relatively potent mu agonist which also displayed weak delta agonist activity. Molecular modeling based on 2D NMR revealed that low energy conformers of peptides with similar biological activities had similar aromatic pharmacophore orientations and interaromatic distances. Peptides that exhibit mu antagonism have interaromatic distances of 7.0-7.9 Angstrom and have their amino terminal aromatic moiety pointing in a direction opposite to the direction that the amino terminus points. Peptides with delta opioid activity displayed an interaromatic distance of <7 Angstrom and had their amino terminal aromatic moiety pointing in the same direction as the amino terminus.
