  摘要：

  聚亚甲基四胺甲辛胺（1）是一种典型的抗毒蕈碱配体，对肌肉nAChR具有显着的亲和力。因此，根据通用模板方法，对1进行结构修饰以提高对肌肉型nAChR的亲和力和选择性。合成的多胺衍生物分别在蛙直肌和鱼雷nAChRs和豚鼠左心房（M（2））和回肠纵肌（M（3））mAChRs上进行测试。所有化合物，如原型1，都是烟碱样受体的非竞争性拮抗剂，同时是M（2）和M（3）mAChRs的竞争性拮抗剂。多胺4-7的生物学特性表明，增加胺官能团的数量和分隔这些氮原子的链长导致nAChRs的效力显着提高。此外，通过合成化合物9和10，进一步研究了胺官能团的数量和类型在与nAChRs相互作用中的作用，显示了四胺8和11，在氮原子之间带有相当刚性的间隔基，而不是非常柔软的聚亚甲基链，在nAChRs处的分布类似于1，而在mAChRs处观察到效力显着降低。带有2-甲氧基苯乙基的四胺12的效力比1低，而带有二苯乙基部分的

  Differential blockade of muscarinic receptor subtypes by polymethylene tetraamines. Novel class of selective antagonists of cardiac M-2 muscarinic receptors

  摘要：

  Several N,N'-bis[6-[(2-methoxybenzyl)amino]hexyl]-1, omega-alkanediamine tetrahydrochlorides were synthesized and evaluated for their blocking activity on muscarinic receptors in guinea pig atria and rat ileum and bladder. The results were compared with those obtained for the classical nonselective muscarinic antagonist atropine. It was discovered that optimum activity is associated with an eight-carbon chain (compound 4) in guinea pig atria whereas, in both rat ileum and bladder, the 12-carbon analogue 7 had the highest activity. In addition, polymethylene tetraamines 1-6 displayed high selectivity toward guinea pig atria muscarinic receptors. The discriminatory power of 1-6 was not shared by 7. All the tetraamines were shown to be competitive antagonists of muscarinic receptors. N,N'-Bis[6-[(2-methoxybenzyl)amino]hexyl]-1,8-octanediamine was the most potent and selective toward muscarinic receptors in atria, with a pA2 value of 8.13 and a selectivity ratio (atria vs. ileum or bladder) of ca. 270. At a concentration of 10 microM, tetraamine 4 did not affect histamine and 5-hydroxytryptamine receptors of guinea pig ileum or alpha-adrenoreceptors of guinea pig atria whereas it inhibited postsynaptic alpha-adrenoreceptors of rat vas deferens with a -log K value of 5.23 and nicotinic receptors of frog rectus abdominis with an IC50 value of 0.23 microM. It is concluded that 4 is a novel, powerful, and selective tool in the characterization of muscarinic receptor subtypes.

  The universal template approach to drug design foresees that a polyamine can be modified in such a way to recognize any neurotransmitter receptor. Thus, hybrids of polymethylene tetraamines and philanthotoxins, exemplified by methoctramine (1) and PhTX-343 (2), respectively, were synthesized to produce novel inhibitors of muscular nicotinic acetylcholine receptors. Polyamines 3-25 were synthesized and their biological profiles were evaluated at frog rectus abdominis muscle nicotinic receptors and guinea pig left atria (M-2) and ileum longitudinal muscle (M-3) muscarinic acetylcholine receptors. All of the compounds, like prototypes 1 and 2, were noncompetitive antagonists of nicotinic receptors while being, like 1, competitive antagonists at,muscarinic M-2 and M-3 receptor subtypes. interestingly, polyamines bearing a low number of methylenes between the nitrogen atoms, as in 3, 6, and 7, displayed a biological profile similar to that of 2: a noncompetitive antagonism at nicotinic receptors in the 7-25 mu M range while not showing any antagonism for muscarinic receptors up to 10 mu M. increasing the number of methylenes separating these nitrogen atoms in methoctramine related tetraamines resulted in a significant improvement; in potency at nicotinic receptors. The most potent tetraamine was 19, bearing a 12 methylene spacer between the nitrogen atoms, which was 12-fold and 250-fold more potent than prototypes 1 and 2, respectively. Tetraamines 9-11, bearing a rather rigid spacer between the nitrogen atoms instead of the very flexible polymethylene chain, displayed a profile similar to that of 1 at nicotinic receptors, whereas a significant decrease in potency was observed at muscarinic M-2 receptors. This finding may have relevance in understanding the mode of interaction with these receptors. Similarly, the constrained analogue 12 of methoctramine showed a decrease in potency at nicotinic and muscarinic M-2 receptors, revealing that the tricyclic system, which incorporates the 2-methoxybenzylamine moiety of 1, does not represent a good pharmacophore for activity at these sites. A most intriguing finding was the observation that the photolabile tetraamine 22 was more potent than methoctramine at nicotinic receptors and, what is more important, it inhibited a closed stale of the receptor.

  Several polymethylene tetraamines related to methoctramine (1) were prepared and evaluated for their blocking activity on M-2 muscarinic receptors in guinea pig atria and ileum. It turned out that antimuscarinic potency depends on the following parameters: (a) nature of the substituent on both inner and outer nitrogens and (b) carbon chain length separating the inner nitrogens as well as the inner and outer nitrogens. Optimum activity at cardiac M-2 muscarinic receptors was associated with the chain lengths present in 1, that is, eight methylenes between the inner nitrogens and six methylenes between the inner and outer nitrogens. With regard to the substituents, replacement of the benzylic moiety of 1 by a 2-furyl or a 5-methyl-2-furyl nucleus resulted in enhanced potency toward cardiac M-2 muscarinic receptors. In fact, furtramine (18) and mefurtramine (19) proved to be more potent and more selective than 1. Moreover, N-methylation of the four nitrogens of 1 gave different effects: methylation of the outer nitrogens, giving 22, caused a significant decrease in activity whereas methylation of the inner nitrogens, yielding 23, resulted in an increase in activity in both atria and ileum.
