    • Described are peptoid compounds of the formula (I): R1-(A)k-(X)m-(B)n-R2 wherein k, n, R1, R2, A and B have the meanings given in the specification, m is 3 to 10, and any X independently of the others being present represents a bivalent radical of partial formula (II), wherein each of R3, R4 and R5, independently of the others, represents hydrogen or a side chain of an alpha -amino acid other than glycine, or R3 and R4 together form an alkylene bridge and R5 is hydrogen, or R4 and R5 together form an alkylene bridge and R3 is hydrogen; with the proviso, that a) at least one of these bivalent radicals has an R3 which is a side chain of an alpha -amino acid other than glycine and proline; b) that at least one R3 other than alkyl or benzyl is present; and c) that the bivalent radicals X together form a TAR-binding, transactivation-deficient oligopeptide analogue of the basic domain of the HIV Tat protein, and any B independently of the others being present represents a bivalent radical of an alpha -amino acid, or salts thereof if a salt-forming group is present. The compounds act, for example, as inhibitors of HIV growth by inhibition of the Tat/TAR-interaction.
    • 描述了式(I)的拟肽化合物:R1-(A)k-(X)m-(B)n-R2其中k,n,R1,R2,A和B具有说明书中给出的含义,m 是3至10,并且存在的其它任何X独立地表示部分式(II)的二价基团,其中R 3,R 4和R 5各自独立地表示氢或α-氨基的侧链 除了甘氨酸以外,还有R3和R4一起形成亚烷基桥,R5是氢,R4和R5一起形成亚烷基桥,R3是氢; 条件是a)这些二价基团中的至少一个具有R3,其是除了甘氨酸和脯氨酸之外的α-氨基酸的侧链; b)存在至少一种不同于烷基或苄基的R 3; 和c)二价基团X一起形成HIV Tat蛋白质的碱性结构域的TAR结合,反式激活缺陷的寡肽类似物,并且与存在的其它B独立的任何B代表α-氨基酸的二价基团, 或其盐,如果存在成盐基团。 该化合物例如通过抑制Tat / TAR-相互作用而作为HIV生长抑制剂。
