  Congener derivatives and conjugates of histamine: synthesis and tissue and receptor selectivity of the derivatives

  摘要：

  A series of 19 congener derivatives and conjugates of histamine was synthesized and tested to determine whether the ligands would alter the conventional histamine activity in various tissues. The derivatives, which contained either branched or unbranched aliphatic groups, aromatic amide groups, or dipeptides, exhibited affinities for histamine type 1 and/or type 2 receptors that were widely different from the progenitor. The p-trifluoromethyl derivative of histamine with an intermediate chain length of four methylenes (compound 13) was the most potent lymphocytes H2 receptor agonist but was inactive on guinea pig myocardium H2 receptors. The deletion of a single methylene chain (compound 12) from this compound resulted in total loss of its H2 activity on lymphocytes and its H1 activity on aorta. Compound 12 became an exclusive H1 agonist on lymphocytes H1 receptors. The dipeptide conjugate (compound 17) and the aliphatic congener derivative (compound 18), both with four methylenes, retained some of the activity on guinea pig myocardium H2 receptors, but lost their activity on lymphocytes H2 receptors. Therefore, histamine can be modified at sites that are at a distance from the imidazole moiety, resulting in tissue selective histamine receptor agonists.

  of ketones by acylation of organomanganous reagents is studied. Thus acid chlorides in ether, symmetrical acid anhydrides in ether or THF and mixed carboxylic-carbonic anhydrides (R'COOCOOEt) in ether are compared, they lead to the corresponding ketones with good or excellent yields. Some problems of reproductibility are encountered and discussed when mixed anhydrides R'COOCOOEt are used in THF. The

  研究了酰化试剂，溶剂和配体的性质对有机锰试剂酰化制备酮的影响。因此，比较了醚中的酰氯，醚或THF中的对称酸酐以及醚中的混合羧酸碳酸酐（R'COOCOOEt），它们可产生相应的酮，收率良好或优异。在THF中使用混合酸酐R'COOCOOEt时，会遇到一些生殖问题。添加多种助溶剂（例如C 6 H 6，AcOEt，CO 3 Et 2，CH 2 CN，CH 2CL 2。在加入酰化剂之前，向反应混合物中加入。）不会影响酮的收率。相比之下，几种配体（例如Me 2 S或Ph 3 P）与有机锰试剂的络合对它们的酰化作用没有后续作用。选择溶剂或配体的主要限制是使用氨基衍生物，这通常会导致酮的产率非常低（例如C 5 H 5 N，TMEDA，Et 3 N）或产率无法再现（例如HMPA）。描述了这些研究的两个应用：
