生物活性

Acetyl tetrapeptide-15 is a synthetic peptide used in the cosmetics for sensitive skin. Acetyl tetrapeptide-15 is derived from endomorphin-2 (Tyr-Pro-Phe-Phe-NH2), a human μ-opioid agonist with selective anti-nociceptive effect. Acetyl tetrapeptide-15 reduces skin hyperreactivity producing inflammatory, chronic and neuropathic pain, by increasing the threshold of neuronal excitability in μ-opioid receptor via an endorphin-like pathway[1].

Argireline acetate (Acetyl hexapeptide-3 acetate) is a non-toxic, skin-permeable, antiwrinkle peptide. Argireline acetate significantly inhibits Ca2+ dependent neurotransmitter release (acetylcholine) at the neuromuscular junction. Argireline acetate has antiwrinkle and anti-aging activity[1][2][3].

体外研究
(In Vitro)

The incubation of Argireline solution in different concentrations with human embryonic kidney HEK-293 (IC50 of 34.862 μM) and neuroblastoma IMR-32 cells (IC50 of 68.458 μM)) for 48 h have dose dependent antiproliferative effect. Argireline solution incubated in different concentrations with HSF has a dose-dependent antiproliferative effect on those cells. Cellular proliferation is not effected in Argireline low concentration[2].

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

体内研究
(In Vivo)

Argireline is applied to the aged mice twice daily for 6 weeks. There is an improvement in the histological structure of skin tissue in the aged mice; the amount of type I collagen fibers increased, while that of type III collagen fibers decreased. Argireline could improve the histological structure of skin tissue and rejuvenate the aging skin[3].

生物活性

N-Acetyl-Ser-Asp-Lys-Pro, an endogenous tetrapeptide secreted by bone marrow, is a specific substrate for the N-terminal site of ACE.

体外研究
(In Vitro)

N-Acetyl-Ser-Asp-Lys-Pro is degraded specifically by ACE, and its plasma level rises substantially during ACE inhibitor therapy. Flow cytometry of rat cardiac fibroblasts treated with N-Acetyl-Ser-Asp-Lys-Pro shows significant inhibition of the progression of cells from G0/G1 phase to S phase of the cell cycle. Moreover, phosphorylation and nuclear translocation of Smad2 is decreased in cardiac fibroblasts treated with N-Acetyl-Ser-Asp-Lys-Pro[1]. N-acetyl-seryl-aspartyl-lysyl-proline appears to exert this function by blocking the action of a stem cell-specific proliferation stimulator and acts selectively on quiescent progenitors[2]. N-Acetyl-Ser-Asp-Lys-Pro inhibits collagenase expression and activation is associated with increased expression of TIMP-1 and TIMP-2. N-Acetyl-Ser-Asp-Lys-Pro normalizes the IL-1β-mediated increase in MMP-2 and MMP-9 activities and MMP-13 expression[3].

体外研究
(In Vitro)

AKBA (Acetyl-11-keto-β-boswellic acid) significantly reduced infarct volumes and apoptotic cells, and also increased neurologic scores by elevating the Nrf2 and HO-1 expression in brain tissues in middle cerebral artery occlusion (MCAO) rats at 48 hours post reperfusion. In primary cultured neurons, AKBA increased the Nrf2 and HO-1 expression, which provided protection against OGD-induced oxidative insult. Additionally, AKBA treatment increased Nrf2 binding activity to antioxidant-response elements (ARE)[1].
AKBA (Acetyl-11-keto-β-boswellic acid) significantly inhibited human colon adenocarcinoma growth, showing arrest of the cell cycle in G1-phase and induction of apoptosis[3].
AKBA (Acetyl-11-keto-β-boswellic acid) triggered significant lipolysis in 3T3-L1 adipocytes as shown by reduced neutral lipids in cytosol and increased free fatty acids in culture medium. Increased lipolysis by AKBA was accompanied by up-regulation of lipolytic enzymes, adipocyte triglyceride lipase (ATGL) and hormone sensitive lipase (HSL), and a decreased expression of lipid droplet stability regulator perilipin. In addition, AKBA (Acetyl-11-keto-β-boswellic acid) treatment reduced phenotypic markers of mature adipocyte aP2, adiponectin and glut-4 in mature adipocytes[5].

AKBA (Acetyl-11-keto-β-boswellic acid) significantly prevented the formation of intestinal adenomatous polyps without toxicity to mice. AKBA’s activity both in the prevention of small intestinal and colonic polyps was more potently than aspirin. Histopathologic examination revealed that AKBA’s effect, that is the reduction of polyp size and degree of dysplasia, was more prominent in larger sized polyps, especially those originating in colon[1].
AKBA (Acetyl-11-keto-β-boswellic acid) administration in mice effectively delayed the growth of HT-29 xenografts without signs of toxicity. The activity of AKBA was more potent than that of aspirin[3].
AKBA (Acetyl-11-keto-β-boswellic acid) exhibited anti-cancer activity in vitro and in vivo. With oral application in mice, AKBA significantly inhibited SGC-7901 and MKN-45 xenografts without toxicity[4].

生物活性

Barlerin (8-O-Acetyl shanzhiside methyl ester) is an iridoid glucoside isolated from the leaves of Lamiophlomis rotata Kudo, a Chinese folk medicinal plant in Xi-zang. Barlerin (8-O-Acetyl shanzhiside methyl ester) could inhibt NF-κB.

NF-κB

 

体外研究
(In Vitro)

Treatment of SH-SY5Y cells with Barlerin (8-O-Acetyl shanzhiside methyl ester) blocks TNF-α-induced nuclear transcription factor κB (NF-κB) activation and decreases high-mobility group box-1 (HMGB-1) expression. [1]. Treatment of H9c2 cells with Barlerin (8-O-Acetyl shanzhiside methyl ester) 9 μM blocks TNF-α-induced NF-κB phosphorylation by blocking High-mobility group box1 (HMGB1) expression[2].

Barlerin (8-O-Acetyl shanzhiside methyl ester) 40 mg/kg demonstrates significant neuroprotective effect even after delayed administration at 4 hr after I/R. Barlerin 40 mg/kg attenuates the histopathological damage, decreases brain swelling, inhibits NF-κB activation and reduces HMGB-1 expression in ischaemic brain tissue[1]. Barlerin (8-O-Acetyl shanzhiside methyl ester) significantly promotes angiogenesis in the ischaemic brain and improves functional outcome after stroke. Barlerin also significantly increases vascularization compared with vehicle treatment. It increases the expression of VEGF, Ang1, phosphorylation of Tie2 and Akt VEGF[3]. Barlerin (8-O-Acetyl shanzhiside methyl ester) significantly shortens capillary blood clotting time and reduces blood loss volume, but does not influence mice activated partial thromboplastin time, prothrombin time or thrombin time. It significantly prolongs euglobulin clot lysis time in hyperfibrinolysis mice[4].

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

Animal Administration
[3][4]

Rats: Barlerin (8-O-Acetyl shanzhiside methyl ester) is prepared in saline. Adult male rats are subjected to 1 hr of middle cerebral artery occlusion (MCAO) and reperfusion, and treated with or without different doses (5 and 10 mg/kg) of ND01, starting 24 hr after ischaemia and reperfusion (I/R) and by intravenous injection daily for 14 days. Neurological functional tests are performed and cerebral Evans blue extravasation is measured[3].

Mouse: Barlerin (8-O-Acetyl shanzhiside methyl ester) is prepared in saline. Male Balb/C mice (20 to 25g) are randomly divided into five groups (saline group, Hemocoagulase, 0.34 KU/kg, i.v. ASM-L, 100 mg/kg, i.v., ASM-M, 250 mg/kg, i.v., ASM-H, 500 mg/kg, i.v.). The drugs and vehicle are injected through vena caudal is 5 min before anesthetized with sodium pentobarbital (200 mg/kg, i.p.). Twenty minutes after injection, blood are drawn from heart. Activated partial thromboplastin time, prothrombin time, thrombin time and fibrinogen are assayed[4].
