  松果体5-羟基色胺-N-乙酰基转移酶的底物和抑制剂的结构活性关系：初步研究。

  摘要：

  色胺，（1-萘基）乙胺和苯乙胺衍生物作为绵羊松果体5-羟色胺-N-乙酰基转移酶（5-HT-NAT）的底物进行了测试，后者是褪黑素合成的关键酶。几乎所有的吲哚衍生物都具有与色胺类似的亲和力（Km = 0.05 mM），而取代的萘和苯基衍生物的效价较低。但是，Km值似乎受取代基的位阻和极性性质影响。萘和苯基衍生物的Vmax值通常比吲哚衍生物的Vmax值高10-20倍，并且未观察到明确的结构活性关系。褪黑激素和几种生物等位衍生物被证明是5-HT-N-乙酰基转移酶的抑制剂。初步数据表明，在5-50 microM的浓度范围内，褪黑激素是一种竞争性抑制剂（IC50 = 10 microM），对松果体自身的合成具有浓度依赖性的抑制作用。然而，生物等位萘衍生物被表征为混合抑制剂。公认的褪黑素能拮抗剂（1-萘基）乙基乙酰氨基也被证明是5-HT-N-乙酰基转移酶的抑制剂（IC50 = 8 microM），是调

  Design and Synthesis of New Naphthalenic Derivatives as Ligands for 2-[125I]Iodomelatonin Binding Sites

  摘要：

  New melatonin-like agents were designed from the frameworks of 2,5-dimethoxyphenethylamine, an important structural moiety for the 5-HT receptor, and (2-methoxynaphthyl)-ethylamine. The compounds were synthesized by classical methods and evaluated in binding assays with chicken brain membranes using 2-[I-125]iodomelatonin as the radioligand. Preliminary studies on the series of N-acyl-disubstituted phenethylamines showed the favorable role of the methoxy group in the ortho position of the side chain on the affinity for the receptor K-i = 8 +/- 0.2 nM) for N-[2-(2-methoxy-5-bromophenyl)ethyl]propionamide (3o). This effect was confirmed in a series of the naphthalene derivatives, a bioisosteric moiety of the indole ring, and several potent ligands for melatonin binding sites were prepared such as N-[2-(2-methoxynaphthyl)ethyl]propionamide (4b) (K-i = 0.67 +/- 0.05 nM) and N-[2-(2,7-dimethoxynaphthyl)ethyl]cyclopropylformamide (K-i = 0.05 +/- 0.004 nM) (4k). Structure-activity relationships are discussed with regard to melatonin and bioisosteric naphthalenic compound 2. The K-i value for 4b was affected to a similar extent to that of melatonin by GTP-gamma-S or Mn2+ in competition experiments, suggesting an agonist profile for this compound.
