  Structure−Activity Relationships of a Novel Class of Endothelin-A Receptor Antagonists and Discovery of Potent and Selective Receptor Antagonist, 2-(Benzo[1,3]dioxol-5-yl)-6-isopropyloxy-4-(4-methoxyphenyl)-2H-chromene-3- carboxylic Acid (S-1255). 1. Study on Structure−Activity Relationships and Basic Structure Crucial for ET_A Antagonism

  摘要：

  A novel series of endothelin-A (ETA) selective receptor antagonists having a 2H-chromene skeleton are described. A lead compound, 2-(benzo[1,3]dioxol-5-yl)-2H-chromene-3-carboxylic acid (3), was found by modifications of our own angiotensin II antagonist. A structure-activity relationship (SAR) study of 3 reveals that the structural requirements essential for potent and selective ETA receptor binding affinity are the m,p-methylenedioxyphenyl, carboxyl, and isopropoxy groups at the 2-, 3-, and 6-positions, respectively, on the (R)-2H-chromene skeleton. The substituent at the 4-position is also important for improving the activity, and various hydrophobic functional groups of 6-9 Angstrom such as liner, branched, and cyclic aliphatic groups, unsubstituted and substituted aryl groups, and even halogen atoms were acceptable. These results suggest that (R)-2-(benzo[1,3]dioxol-5-yl)-6-isopropoxy-2H-chromene-3-carboxylic acid, formula 108, is the crucial basic structure to be recognized by the ETA receptor. The most potent compound is (R)-48 (S-1255), which binds to the ETA receptor with an IC50 value of 0.19 nM and is 630-fold selective for the ETA receptor than for the ETB receptor. This compound has 55% oral bioavailability in rats. On the basis of the SAR, the roles of each substituent in the receptor binding are discussed.

  single hydroxyl can be selectively added to a flavanone A- or B-ring at any position. We are also the first to develop a procedure that separates the seven isomers by GC and characterizes the mass spectra of the isomers. Both the synthetic method and the GC-MS conditions may become important tools during future flavanone metabolism and oxidation studies.

  selective catalytic hydroxylation of arenes remains an ongoing research challenge because of the relative inertness of aryl carbon-hydrogen bonds, the higher reactivity of the phenolic products leading to over-oxidized by-products, and the frequently insufficient regioselectivity. We report that iron coordinated by a bioinspired l-cystine–derived ligand can catalyze undirected arene carbon-hydrogen hydroxylation

  由于芳基碳氢键的相对惰性、酚类产物的较高反应性导致过度氧化的副产物以及经常不足的区域选择性，芳烃的可持续、非定向和选择性催化羟基化仍然是一项持续的研究挑战。我们报告说，铁由受生物启发的l-胱氨酸衍生的配体可以催化非定向芳烃碳氢羟基化，过氧化氢作为末端氧化剂。该反应以其广泛的底物范围、出色的选择性和良好的产率而著称，并且表现出与氧化敏感官能团的相容性，如醇、多酚、醛，甚至硼酸。该方法非常适合通过多重碳氢羟基化合成多酚，以及天然产物和药物分子的后期功能化。
