Angstrom6 (A6 Peptide) 是一种来源于单链尿激酶纤溶酶原激活剂 (scuPA) 的8个氨基酸的肽,可干扰uPA/uPAR级联反应并消除下游效应。Angstrom6 与 CD44 结合,抑制肿瘤细胞的迁移、侵袭和转移,调节 CD44 介导的细胞信号。
生物活性 | Angstrom6 (A6 Peptide) is an 8 amino-acid peptide derived from single-chain urokinase plasminogen activator (scuPA) and interferes with theuPA/uPARcascade and abrogates downstream effects. Angstrom6 binds to CD44 resulting in the inhibition of migration, invasion, and metastasis of tumor cells, and the modulation of CD44-mediated cell signaling[1][2]. |
体外研究 (In Vitro) | Angstrom6 is effective at blocking the migration of the OVCAR8, OVCAR3, ES2, IGROV-1, MDA-MB-468, and MDA-MB361 cells with IC50s in the range of 10 to 100 nM[3]. Angstrom6 potentiates the CD44-dependent adhesion of cancer cells to hyaluronic acid and activated CD44-mediated signaling, as evidenced by focal adhesion kinase and MAP/ERK kinase phosphorylation[3].

体内研究 (In Vivo) | Angstrom6 (100 mg/kg; s.c. twice daily) reduces the number of lung foci generated by the i.v. injection of B16-F10 melanoma cells by 50%[3].
Animal Model: | C57Bl/6 mice (bearing B16-F10 cells)[3] | Dosage: | 100 mg/kg | Administration: | S.c.; twice a day for 11 days | Result: | Reduced the number of lung nodules and reduced the number of lung metastases to 50% of control. |
