  Novel collagen mimics are disclosed with a tripeptide unit having the formula (Xaa-Yaa-Gly) n , where one of the positions Xaa or Yaa is a bulky, non-electron withdrawing proline derivative. By substituting a proline derivative at either the Xaa or Yaa position in the native collagen helix, the stability of the helix is increased due solely to steric effects relative to prior known collagen-related triple helices. Methods are also disclosed for making the novel collagen mimics.

  揭示了一种具有三肽单元的新型胶原模拟物，其化学式为（Xaa-Yaa-Gly）n，其中Xaa或Yaa位置中的一个是体积庞大的非电子吸引脯氨酸衍生物。通过在原生胶原螺旋中的Xaa或Yaa位置之一替换脯氨酸衍生物，仅通过立体效应相对于先前已知的胶原相关三肽螺旋，可以增加螺旋的稳定性。还揭示了制备新型胶原模拟物的方法。

  This invention relates to a collagen polypeptide comprising a tripeptide motif having the formula (ProYaaGly) n , where Yaa is an O-methylated amino acid residue and “n” is the number of motif repeats. Preferred O-methylated amino acid residues at the Yaa position include (2S,4R)-4-methoxyproline. Other suitable amino acid residues at that position include O-mono or O-di-halogenated methylproline. Also, disclosed is a method of making a synthetic or a semi-synthetic collagen polypeptide molecule having increased stability relative to natural collagen. The strengthened collagen molecules are suitable for use in biomaterials for the medical field or in leather-related products prepared by the tanning industry.

  本发明涉及一种胶原蛋白多肽，其包含具有公式（ProYaaGly）n的三肽基序，其中Yaa是O-甲基化的氨基酸残基，“n”是基序重复的次数。在Yaa位置的首选O-甲基化氨基酸残基包括（2S，4R）-4-甲氧基脯氨酸。该位置上的其他适当氨基酸残基包括O-单或O-双卤代甲基脯氨酸。此外，还揭示了一种制备具有相对于天然胶原蛋白增强稳定性的合成或半合成胶原蛋白分子的方法。强化的胶原分子适用于医学领域的生物材料或由制革工业制备的皮革相关产品。

  [EN] Novel collagen mimics are disclosed with a tripeptide unit having the formula (Xaa-Yaa-GIy)n, where one of the positions Xaa or Yaa is a bulky, non-electron withdrawing proline derivative. By substituting a proline derivative at either the Xaa or Yaa position in the native collagen helix, the stability of the helix is increased due solely to steric effects relative to prior known collagen-related triple helices.

  [FR] La présente invention concerne de nouveaux mimétiques de collagène avec un motif tripeptidique de formule (Xaa-Yaa-GIy)n, où une des positions de Xaa ou Yaa est un dérivé de proline massif non extracteur d'électrons. Grâce à la substitution d'un dérivé de proline à la position Xaa ou Yaa dans l'hélice de collagène natif, la stabilité de l'hélice est accrue due uniquement aux effets stériques par rapport aux hélices triples associés au collagène connus. L'invention concerne également des procédés de fabrication de nouveaux mimétiques de collagène.
