    色酮和多奈哌齐杂种作为新型多能胆碱酯酶和单胺氧化酶抑制剂,可潜在治疗阿尔茨海默氏病
    摘要:
    设计,合成并评估了一系列色酮和多奈哌齐杂化物,作为多能胆碱酯酶(ChE)和单胺氧化酶(MAO)抑制剂,可用于治疗阿尔茨海默氏病(AD)。体外研究表明,这些化合物中的绝大多数对BuChE和AChE表现出有效的抑制活性,并且对h MAO-B具有明显的选择性抑制作用。特别地,化合物5c呈现出对ChE抑制的最平衡的电位(BuChE:IC 50 = 5.24μM; AChE:IC 50 = 0.37μM)和h MAO-B选择性(IC 50 = 0.272μM,SI = 247)。分子建模和动力学研究表明5c是一种混合型抑制剂,可同时与AChE的外围和活性位点结合。它也是一种竞争性抑制剂,占据了MAO-B的底物和入口腔。此外,化合物5c可以穿透血脑屏障(BBB),并且对大鼠嗜铬细胞瘤(PC12)细胞显示出低毒性。总而言之,这些结果表明化合物5c可能是希望的多靶点候选药物,可能对阿尔茨海默氏病的治疗产生影响。

    Herein is reported an efficient, one-pot domino process through a 1,6-aza-Michael addition-triggered sequence and an original Mitsunobu-type concerted sequence for the synthesis of tetracyclic systems containing a bis-N,O-acetal junction. This methodology led to the construction of four new bonds, the cleavage of three C–O bonds, and the generation of an asymmetric center. Mitsunobu activation afforded

  • 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)-2<i>H</i>-chromene-3- carboxylic Acid (S-1255). 1. Study on Structure−Activity Relationships and Basic Structure Crucial for ET<sub>A</sub> Antagonism

    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.
