    • Thrombin is now known to mediate a number of potent biological effects on cells bearing high-affinity thrombin receptors. These effects depend, at least in part, upon receptor occupancy signals generated by thrombin's interaction with the high affinity thrombin receptor. The present inventors have formulated synthetic thrombin derivatives capable of selectively stimulating or inhibiting thrombin receptor occupancy signals. The stimulatory thrombin derivatives to bind to cell surface thrombin receptors and stimulate DNA synthesis in cells treated with non-mitogenic concentrations of alpha-thrombin or phorbol myristate acetate. Thus, these peptides, which have both a thrombin receptor binding domain and a segment of amino acids with a sequence common to a number of serine proteases, appear to generate receptor-occupancy dependent mitogenic signals. The inhibitory derivatives, which have no serine esterase conserved amino acid sequences bind to thrombin receptors without generating receptor-occupancy dependent mitogenic signals. This invention describes the peptides and methods for using them to promote cell growth and wound healing or to inhibit scar formation, tissue adhesions, and tumor metastasis and angiogenesis.
    • 凝血酶现在已知可以介导一些对高亲和力凝血酶受体的细胞的有力的生物学作用。 这些作用至少部分取决于凝血酶与高亲和力凝血酶受体相互作用产生的受体占有率信号。 本发明人已经制备了能够选择性地刺激或抑制凝血酶受体占据信号的合成凝血酶衍生物。 刺激性凝血酶衍生物结合细胞表面凝血酶受体并刺激用非丝分裂浓度的α-凝血酶或佛波酮肉豆蔻酸乙酸酯处理的细胞中的DNA合成。 因此,这些具有凝血酶受体结合结构域和具有多个丝氨酸蛋白酶共有序列的氨基酸片段的这些肽似乎产生受体占据依赖的促有丝分裂信号。 没有丝氨酸酯酶保守氨基酸序列的抑制性衍生物结合凝血酶受体而不产生受体占有依赖的有丝分裂信号。 本发明描述了使用它们促进细胞生长和伤口愈合或抑制瘢痕形成,组织粘连和肿瘤转移和血管生成的肽和方法。
