RGD peptidomimetics touch DNA: A few RGD cyclic peptidomimetics, each incorporating a densely substituted β‐lactam moiety, were prepared, and their effect on extracellular adhesion and intracellular gene regulation through αVβ3 integrin was studied in human endothelial cells (HUVECs). Surprisingly, the cyclic tetrapeptide with a deleted glycine residue and its parent RGD peptidomimetic displayed practically
RGD肽模拟触摸DNA:少数RGD环状肽模拟物,每个结合有密集地取代的β内酰胺部分,制备,和通过α它们对细胞外粘附和细胞内的基因调控作用V β 3整联在人内皮细胞(HUVEC)的影响。令人惊讶的是,带有缺失的甘氨酸残基的环状四肽及其母体RGD拟肽表现出实际上相反的血管生成基因调节活性。
