    • Libraries of novel backbone-cyclized peptide analogs are formed by means of bridging groups attached via the alpha nitrogens of amino acid derivatives to provide novel non-peptidic linkages. Novel building units used in the synthesis of these backbone-cyclized peptide analogs are N(((-functionalized) amino acids constructed to include a spacer and a terminal functional group. One or more of these N(((-functionalized) amino acids are incorporated into a library of peptide sequences, preferably during solid phase peptide synthesis. The reactive terminal functional groups are protected by specific protecting groups that can be selectively removed to effect either backbone-to-backbone or backbone-to-side chain cyclizations. The invention is exemplified by libraries of backbone-cyclized bradykinin analogs, somatostatin analogs, BPI analogs and Substance P analogs having biological activity. Further embodiments of the invention are Interleukin-6 receptor derived peptides having ring structures involving backbone cyclization.

    • The design and the synthesis of backbone cyclic peptide analogs which functionally mimic the nuclear localization signal (NLS) region of macromolecules is disclosed. The principles of the invention are exemplified for the NLS sequences of the human immunodeficiency virus type 1 proteins MA, Vpr, Tat and NLS-like sequences of HIV-1 protein Vif. We disclose the discovery of a novel, highly potent backbone cyclic peptide, designated BCvir, which inhibits nuclear import with an IC50 value of 35 nM. This inhibitory potency is to be compared to 12 &mgr;M exhibited by the linear parent HIV-1 MA NLS peptide. BCvir also reduced HIV-1 production by 75% in infected non-dividing cultured human T-cells and was relatively resistant to tryptic digestion. These properties render backbone cyclic peptide analogs of NLS or NLS-like sequences as candidates for novel drugs based on blocking nuclear import of viral genomes.
    • 公开了功能上模拟大分子的核定位信号(NLS)区域的骨架环肽类似物的设计和合成。 对于HIV-1蛋白Vif的人免疫缺陷病毒1型蛋白MA,Vpr,Tat和NLS样序列的NLS序列,举例说明了本发明的原理。 我们公开了一种称为BCvir的新型高效骨架环肽的发现,其抑制核导入,IC50值为35nM。 将该抑制效力与线性亲本HIV-1 MA NLS肽显示的12μM进行比较。 在感染的非分裂培养的人类T细胞中,BCvir还将艾滋病毒1的产量降低了75%,并且相对抗胰蛋白酶消化。 这些性质使NLS或NLS样序列的骨架环肽类似物作为基于阻断核进入病毒基因组的新型药物的候选物。
