  Synthesis of truncated analogues of preptin-(1–16), and investigation of their ability to stimulate osteoblast proliferation

  摘要：

  Preptin, a 34-amino acid residue peptide hormone is co-secreted with insulin from the β-pancreatic cells and is active in fuel metabolism. We have previously established that a shorter fragment of preptin, namely preptin-(1–16), stimulates bone growth by proliferation and increasing the survival rate of osteoblasts. This was demonstrated in both in vitro and in vivo models. These findings suggest that preptin-(1–16) could play an important role in the anabolic therapy of osteoporosis. However, due to the large size of the peptide it is not an ideal therapeutic agent. The aim of this study was to identify the shortest preptin analogue that retains or even increases the bone anabolic activity as compared to the parent preptin-(1–16) peptide. Truncations were made in a methodical manner from both the N-terminus and the C-terminus of the peptide, and the effect of these deletions on the resulting biological activity was assessed. In order to improve the enzymatic stability of the shortest yet active analogue identified, ruthenium-catalysed ring closing metathesis was used to generate a macrocyclic peptide using allylglycine residues as handles for ring formation. We have successfully identified a short 8-amino acid preptin (1–8) fragment that retains an anabolic effect on the proliferation of primary rat osteoblasts and enhances bone nodule formation. Preptin (1–8) is a useful lead compound for the development of orally active therapeutics for the treatment of osteoporosis.

  immunotherapy has gained increasing attention due to its potential specificity and lack of adverse side effects when compared to more traditional modes of treatment. Toll-like receptor 2 (TLR2) agonists are lipopeptides possessing the S-[2,3-bis(palmitoyloxy)propyl]-l-cysteine (Pam2Cys) motif and exhibit potent immunostimulatory effects. These agonists offer a means of providing “danger signals” in order

  与更传统的治疗方式相比，癌症免疫疗法由于其潜在的特异性和缺乏不良副作用而受到越来越多的关注。Toll样受体2（TLR2）激动剂是脂肽，具有S- [2,3-双（棕榈酰氧基）丙基] -1-半胱氨酸（Pam 2 Cys）基序，并表现出强大的免疫刺激作用。这些激动剂提供了一种提供“危险信号”的方式，以激活针对肿瘤抗原的免疫系统。因此，在寻找潜在的癌症免疫刺激剂方面，TLR2激动剂的开发具有吸引力。Pam 2的现有SAR研究带有TLR2的半胱氨酸表明，对活性的结构要求在大多数情况下是非常难以忍受的。我们已经研究了立体化学的重要性，N末端酰化的影响以及Pam 2 Cys结合的脂肽中两个酯官能团之间对TLR2活性的同源性。的[R非对映体是显著比更有效小号非对映体和Ñ末端修饰通常降低TLR2活性。最显着地，同源性产生了对含有天然Pam 2 Cys的构建体具有相对活性的类似物。
