Patent number: 6265375Abstract: 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 disclosed are N&agr;(&ohgr;-functionalized) amino acids constructed to include a spacer and a terminal functional group. One or more of these N&agr;(&ohgr;-functionalized) amino acids are incorporated into a peptide sequence, 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 specifically exemplified by backbone cyclized bradykinin antagonists having biological activity. Further embodiments of the invention are somatostatin analogs having one or two ring structures involving backbone cyclization.Type: GrantFiled: July 22, 1998Date of Patent: July 24, 2001Assignees: Yissum Research Development Co. of the Hebrew University, Peptor LimitedInventors: Chaim Gilon, Doron Eren, Irina Zeltser, Alon Seri-Levy, Gal Gitan, Dan Muller
