  Structure–Affinity Relationships (SARs) and Structure–Kinetics Relationships (SKRs) of K_v11.1 Blockers

  摘要：

  K(v)11.1 (hERG) blockers with comparable potencies but different binding kinetics might display divergent proarrhythmic risks. In the present study, we explored structure-kinetics relationships in four series of K(v)11.1 blockers next to their structure affinity relationships. We learned that despite dramatic differences in affinities and association rates, there were hardly any variations in the dissociation rate constants of these molecules with residence times (RTs) of a few minutes only. Hence, we synthesized 16 novel molecules, in particular in the pyridinium class of compounds, to further address this peculiar phenomenon. We found molecules with very short RTs (e.g., 0.34 min for 37) and much longer RTs (e.g., 105 min for 38). This enabled us to construct a k(on)-k(off)-K-D kinetic map for all compounds and subsequently divide the map into four provisional quadrants, providing a possible framework for a further and more precise categorization of K(v)11.1 blockers. Additionally, two representative compounds (21 and 38) were tested in patch clamp assays, and their RTs were linked to their functional IC50 values. Our findings strongly suggest the importance of the simultaneous study of ligand affinities and kinetic parameters, which may help to explain and predict K(v)11.1-mediated cardiotoxicity.

• Visible-Light-Promoted, Catalyst-Free Gomberg–Bachmann Reaction: Synthesis of Biaryls
  作者：Juyoung Lee、Boseok Hong、Anna Lee

  DOI：10.1021/acs.joc.9b00557

  日期：2019.7.19

  Biaryls were synthesized via a novel visible-light-promoted Gomberg–Bachmann reaction that does not require a photosensitizer or any metal reagents. The formation of an electron donor–acceptor complex between aryl diazonium salts and pyridine allows, under visible-light irradiation, the synthesis of biaryls in moderate-to-high yields.

• Aryl radicals from hexazadienes and tetrazenes
  作者：Donald Mackay、Deane Douglas McIntyre

  DOI：10.1139/v82-148

  日期：1982.4.15

  Aryl radicals are produced from both ends of the hexazadienes 1 and 2 and from the tetrazene 3, either thermally or photolytically. They attack aromatic compounds in the nucleus, the yield of biaryl being in the range 40–70%, though it can be made nearly quantitative by using m-dinitrobenzene as an additive. The aryl radicals also oxidize 2-propanol to acetone, the reduction products being the halogenobenzene and 1,2-diacetylhydrazine.Photolysis of 1 goes mainly by way of the tetrazene 3, and this may also be a significant pathway in the thermal reaction. Azodiacetyl is an intermediate in the thermal reaction of 1 with 2-propanol and may be generally so in all its reactions.Radical induced decomposition is believed to be important in the reactions of 1, 2, and 3, and it is probably responsible for the formation of 1-acetyl-1-arylhydrazines, routinely produced in yields of up to 25%.

  芳基自由基可以通过热力或光解产生自六氮烯1和2的两端以及四氮烯3。它们攻击芳香化合物的核，生成的双芳基产率在40-70%范围内，但通过使用m-二硝基苯作为添加剂几乎可以达到定量。芳基自由基还可以将异丙醇氧化为丙酮，还原产物为卤代苯和1,2-二乙酰肼。光解1主要经过四氮烯3进行，这在热反应中也可能是一个重要途径。三氮乙酰基是1与异丙醇热反应的中间体，可能在所有反应中普遍存在。自由基诱导分解被认为在1、2和3的反应中很重要，可能是产生1-乙酰基-1-芳基肼的原因，通常产率高达25%。

This unprecedented level of activity allows the use of highly functionalized (Knochel-type) Grignard reagents. Additionally, the tolerance of the protocol toward a wide variety of functional groups allows for the synthesis of valuable compounds, including heterocyclic
