  Structure−Activity Relationships of 2,N⁶,5‘-Substituted Adenosine Derivatives with Potent Activity at the A_2B Adenosine Receptor

  摘要：

  2, N-6, and 5'-substituted adenosine derivatives were synthesized via alkylation of 2-oxypurine nucleosides leading to 2-arylalkylether derivatives. 2-(3-(Indolyl)ethyloxy)adenosine 17 was examined in both binding and cAMP assays and found to be a potent agonist of the human A(2B)AR. Simplification, altered connectivity, and mimicking of the indole ring of 17 failed to maintain A2BAR potency. Introduction of N-6-ethyl or N-6-guanidino substitution, shown to favor A2BAR potency, failed to enhance potency in the 2-( 3-( indolyl)ethyloxy) adenosine series. Indole 5 ''- or 6 ''-halo substitution was favored at the A(2B)AR, but a 5'-N-ethylcarboxyamide did not further enhance potency. 2-(3 ''-(6 ''-Bromoindolyl)ethyloxy)adenosine 28 displayed an A(2B)AR EC50 value of 128 nM, that is, more potent than the parent 17 (299 nM) and similar to 5'-N-ethylcarboxamidoadenosine (140 nM). Compound 28 was a full agonist at A(2B) and A(2A)ARs and a low efficacy partial agonist at A(1) and A(3)ARs. Thus, we have identified and optimized 2-(2-arylethyl) oxo moieties in AR agonists that enhance A(2B)AR potency and selectivity.

• A Photoredox‐Induced Stereoselective Dearomative Radical (4+2)‐Cyclization/1,4‐Addition Cascade for the Synthesis of Highly Functionalized Hexahydro‐1 <i>H</i> ‐carbazoles

  synthesis of functionalized hexahydrocarbazoles was developed based on an unprecedented photoredox‐induced dearomative radical (4+2)‐cyclization/1,4‐addition cascade between 3‐(2‐iodoethyl)indoles and acceptor‐substituted alkenes. The title reaction simultaneously generates three C−C bonds and one C−H bond, along with three contiguous stereogenic centers. The hexahydro‐1H‐carbazole products are highly valuable

  基于前所未有的光氧化还原诱导的3–（2-碘乙基）吲哚与受体取代的烯烃之间的脱氧自由基（4 + 2）-环化/ 1,4-加成级联反应，开发了功能化六氢咔唑的立体选择性合成方法。标题反应同时生成三个C-C键和一个C-H键，以及三个连续的立体中心。六氢-1 H-咔唑产品是合成新型抗生素以及多环吲哚啉生物碱的非天然环同源物的极有价值的中间体。
