  Synthesis of Cα methylated carboxylic acids: isosteres of arginine and lysine for use as N-terminal capping residues in polypeptides

  摘要：

  Replacement of the N-terminal alpha-amine with the isosteric methyl functionality in bioactive peptides can influence various pharmacokinetic parameters, including hydrophobicity and stability. C-alpha methylated amino acid analogues are thus of great interest to expand the repertoire of nonnatural synthons available as N-terminal 'capping' residues for peptide-based drug design. Several novel arginine and lysine analogues stereo selectively modified in the C-alpha position with a methyl group in place of the alpha-amine were prepared. (c) 2005 Elsevier Ltd.

  Effect of Progressive Benzyl Substitution on the Conformations of Aminocaproic Acid-Cyclized Dipeptides

  摘要：

  The constraint of dipeptides into a beta -turn conformation can be accomplished by linking the two ends of a standard dipeptide with a linker derived from aminocaproic acid (Aca). To elucidate the possibility of using substituted Aca linkers in peptidomimetic design, a series of five macrocycles composed of a monobenzylated Aca linker (containing the benzyl group on each of the five methylene groups of the parent linker) and Gly-Gly were synthesized. The requisite linkers were made by regiochemically controlled ring expansion techniques (for substitution on Aca positions C-3, C-4, or C-5), an Evans alkylation route (for C-2), or by chain extension of L-phenylalanal (for C-6). The solution-phase conformations of the macrocycles were examined by NMR and CD techniques; in addition, crystal structures of the C-4- and C-6-benzyl-substituted linkers were obtained. Four out of the five macrocycles were found to exist with the dipeptide portion taking up either a type II or II ' beta -turn conformation, but the Gly-Gly unit in the compound derived from 4-benzyl-Aca did not correspond to one of the standard beta -turn types.

  Tumor targeting anticancer drug conjugates that contain a tumor recognition motif (homing device) are of high current relevance. Cryptophycins, naturally occurring cytotoxic cyclo-depsipeptides, have been modified by total synthesis to provide analogues suitable for conjugation to peptide-based homing devices. An array of functionalized beta(2)-amino acids was synthesized and incorporated into cryptophycins. All analogues proved to be highly active in the cytotoxicity assay using the human cervix carcinoma cell line KB-3-1 and its multidrug-resistant subclone KB-V1. Conformational analysis of cryptophycin-52 and two synthetic analogues was performed by NMR and MD methods to obtain information on the influence of the unit C configuration on the overall conformation. An azide-functionalized cryptophycin was connected by CuAAC to an alkyne-containing fluorescently labeled cyclic RGD-peptide as the homing device for internalization studies. Confocal fluorescence microscopy proved integrin-mediated internalization by endocytosis and final lysosomal localization of the cryptophycin prodrug.

  [GRAPHICS]The constraint of dipeptides with linkers derived from 6-aminocaproic acid (Aca) is a useful means of constructing a beta-turn peptidomimetic, The extension of this concept to the mimicry of a tripeptide entails the incorporation of a side chain moiety on either end of the Aca chain. The synthesis and conformational analysis of two exemplary compounds is discussed.
