Spiraeoside elevates HG stimulation-caused the decrease in the expression levels of p-Akt, nuclear Nrf2, and HO-1 in AC16 cells (the effects of Spiraeoside are reversed by LY294002)[1].
Spiraeoside protects AC16 cells against HG-induced oxidative stress, cell injury, and apoptosis[1].
Spiraeoside activates the PI3K/Akt/Nrf2 pathway in AC16 cells on exposure to HG[1].
Spiraeoside protects AC16 cells against HG-induced apoptosis through the PI3K/Akt/Nrf2 pathway[1].

生物活性

Gluten exorphin C is an opioid peptide derived from wheat gluten. Its IC50 values are 40 μM and 13.5 μM for μ opioid and δ opioid activities in the GPI and MVD assays, respectively.

IC50 Target

IC50: 40 μM (μ opioid), 13.5 μM (δ opioid)[1]

体外研究
(In Vitro)

Gluten exorphin C, a novel opioid peptide, is isolated from the pepsin-trypsin-chymotrypsin digest of wheat gluten. Gluten exorphin C is evaluated its opioid activities by the GPI and MVD assays and its receptor affinities by radioreceptor assays. Its IC50s are 40 μM and 13.5 μM in the GPI and the MVD assays, respectively. Gluten exorphin C has a structure quite different from any of the endogenous and exogenous opioid peptides ever reported in that the N terminal Tyr is the only aromatic amino acid. The analogs containing Tyr-Pro-X-Ser-Leu are synthesized to study its structure-activity relationship. Peptides in which X is an aromatic amino acid or an aliphatic hydrophobic amino acid has opioid activity[1].

生物活性

Vapreotide acetate (RC-160 acetate; BMY-41606 acetate) is a neurokinin-1 (NK1) receptor antagonist, with an IC50 of 330 nM.

体外研究
(In Vitro)

Vapreotide attenuates the Substance P (SP)-triggered intracellular calcium increases and NF-κB activation in a dose-dependent manner. Vapreotide also inhibits SP-induced IL-8 and MCP-1 production in HEK293-NK1R and U373MG cell lines. Vapreotide inhibits HIV-1 infection of human MDM in vitro, an effect that is reversible by SP pretreatment[1]. Vapreotide significantly inhibits GH-, PRL, and/or alpha-subunit release by human GH-secreting pituitary adenoma cells in concentrations as low as 10-12-10-14 M. Vapreotide inhibits GH release with an IC50 of 0.1 pM[2]. Vapreotide exhibits moderate-to-high affinities for SSTR2, -3, and -5 (IC50=0.17, 0.1 and 21 nM, respectively) and low affinity for SSTR1 and -4 (IC50=200 and 620 nM, respectively). RC-160 inhibits serum-induced proliferation of CHO cells expressing SSTR2 and SSTR5 (EC50=53 and 150 pM, respectively)[3].

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

体内研究
(In Vivo)

In cirrhosis, bleeding by rupture of oesophagogastric varices is a severe complication of portal hypertension. The acute administration of vapreotide to rats decreases collateral circulation blood flow while chronic administration attenuated its development[4]. Tumor volumes and weights are reduced by about 40% by RC-160 by s.c. injections at doses of 100 μg/day/animal. Vapreotide can inhibit the growth of androgen-independent prostate cancer when the therapy is started at an early stage of tumor development[5].

Cell Assay
[3]

CHO cells are cultured in aMEM containing 10% FCS. After overnight attachment, the medium is changed to a MEM containing either 10% FCS or insulin with and without vapreotide. Cell growth is measured after 24 h by counting cells with a Coulter counter model ZM[3].

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

Animal Administration
[4][5]

Rats: Acute effects are evaluated at baseline and 30 min after placebo or vapreotide (8 μg/kg/hr) infusions in DMNA rats. Chronic hemodynamic effects are evaluated using subcutaneous implants for five weeks in anesthetized DMNA rats and in sham rats. Hemodynamic measurements include splenorenal shunt blood flow by the transit time ultrasound method and cardiac output by the combined dilution–TTU method[4].

Mice: Nude mice bearing xenografts of the androgen-independent human prostate-cancer cell line PC-3 are treated for 4 weeks with somatostatin analog vapreotide (20 μg/day/animal), bombesin/gastrin-releasing peptide (GRP) antagonist, or the combination of both peptides. Tumor volumes and weights are measured[5].
