生物活性

Semax is a BBB-penetrable adrenocorticotropic hormone-like peptide and can form stable complexes with Cu2+. Semax is a synthetic peptide analog of Adrenocorticotropic hormone (ACTH) (4-10). Semax has immunomodulatory, nootropic and neuroprotective activities. Semax can be used in the research of central nervous system diseases such as Alzheimer's disease and cerebral ischemia[1][2][3][4][5].

体外研究
(In Vitro)

Semax (25-100 μM, 48 h) 可降低 Aβ 寡聚体的水平[1]
Semax (100 nM) 可提高基底前脑胆碱能神经元的存活率,并刺激离体基底前脑组织培养物中胆碱乙酰转移酶的活性[2]
Semax (10 μM, 0-24 h) 在新生大鼠基底前脑来源的神经胶质细胞中,可提高 BDNF 和 NGF 水平[3]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Real Time qPCR[3]

Cell Line: Glial cells derived from the basal forebrain of newborn rats
Concentration: 10 μM
Incubation Time: 0, 0.5, 1, 2, 3, 4, 8, 16 and 24 h
Result: Increased the mRNA levels of the BDNF and NGF.
体内研究
(In Vivo)

Semax (100 μg/kg; 腹腔注射; 单剂量) 在大鼠局灶性脑缺血模型中具有改善作用[4]
Semax (0.15 mg/kg; 腹腔注射; 单剂量) 可增加小鼠下丘脑和纹状体中 5-HIAA 的浓度[5]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Ischemia (pMCAO) rats[4]
Dosage: 100 μg/kg
Administration: Intraperitoneal injections (i.p.), performed 15 min, 1, 4 and 8 h after permanent middle cerebral artery occlusion (pMCAO).
Result: Affected the expression of genes related to the immune system. At 3 hours after pMCAO, it influenced the expression of genes regulating the activity of immune cells such as macrophages, neutrophils, and lymphocytes. At 24 hours after pMCAO, the effect on the immune response was significantly increased, with over 50% of the genes with altered expression involved in the immune response.
Affected the expression of genes related to the vascular system. At 3 hours after pMCAO, it influenced genes involved in vasculogenesis, hematopoiesis, and endothelial cell migration. At 24 hours after pMCAO, it affected the development of endothelial tissue, the migration of smooth muscle cells, and the activation of blood cells.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
