This invention is directed to tetrahydronaphthalene compounds of the formula ##STR1## wherein R.sup.1 is hydrogen, bromine, cyano, formyl, hydroxy, lower alkyl, lower alkenyl, lower alkynyl, lower alkoxy, aryloxy, lower aralkoxy or aryl; R.sup.2 is an amino acid residue or a chain of 2 to 20 amino acid residues wherein reactive moieties in the side chains of the amino acid residue(s) is/are protected or unprotected, and wherein the amino group of the N-terminal amino acid is a free or protected amino group; A.sup.1, A.sup.2, A.sup.3 and A.sup.4 each are .alpha.-amino acid residues wherein A.sup.1 and A.sup.2 are in the L configuration and A.sup.3 and A.sup.4 are in the D configuration when the .alpha.-C atom of said .alpha.-amino acid residue is asymmetric; X is oxygen or sulphur; Y is a residue of the formula ##STR2## n is 0 or 1; R.sup.3 is hydrogen or lower alkyl; R.sup.4 is hydrogen or lower alkyl; and Z and the two C atoms together are an aromatic ring selected from the group of benzene, furan, thiophene, pyridine or pyrimidine, wherein said aromatic ring is substituted or unsubstituted; and salts thereof and their intermediates. The compounds are useful as mimetics of exposed helical domains of proteins in order to clarify their role with respect to interactions with other proteins or with DNA or RNA through .alpha.-helical conformation. They are therefore valuable aids in the determination of biologically active peptide sequences and are accordingly so-called "research tools". They are also potentially useful as medicaments.
这项发明涉及以下结构的四氢萘化合物 ##STR1## 其中R.sup.1为氢、溴、氰基、甲酰基、羟基、较低烷基、较低烯基、较低炔基、较低烷氧基、芳基氧基、较低芳基氧基或芳基;R.sup.2为氨基酸残基或由2至20个氨基酸残基组成的链,其中氨基酸残基的侧链中的反应性基团是保护的或未保护的,并且N-末端氨基酸的氨基为自由或保护的氨基;A.sup.1、A.sup.2、A.sup.3和A.sup.4各自为α-氨基酸残基,其中当所述α-氨基酸残基的α-C原子是不对称的时,A.sup.1和A.sup.2为L构象,A.sup.3和A.sup.4为D构象;X为氧或硫;Y为以下结构的残基 ##STR2## n为0或1;R.sup.3为氢或较低烷基;R.sup.4为氢或较低烷基;Z和这两个碳原子一起构成从苯、呋喃、噻吩、吡啶或嘧啶中选择的芳香环,其中所述芳香环是取代的或未取代的;以及它们的盐和中间体。这些化合物可用作蛋白质暴露的螺旋结构域的模拟物,以澄清其在与其他蛋白质或DNA或RNA之间通过α-螺旋构象相互作用方面的作用。因此,它们是确定生物活性肽序列的有价值辅助工具,因此被称为“研究工具”。它们也有潜在用途作为药物。
