Product Introduction
Bioactivity
英文名: Diquafosol tetrasodium
描述: Diquafosol tetrasodium (INS365) 是一种 P2Y2 受体激动剂,可刺激眼组织粘蛋白的分泌。它可改善泪膜稳定性和视觉功能,作为干眼症的局部治疗。
细胞实验: The viabilities of human corneal epithelial cells (HCECs) were determined using a MTT assay.?Cells (100 μl;?5×104 cell/mL) were plated in 96-well tissue-culture plates and incubated at 37℃ in 5% CO2 for 24 to 48 h until cultures were subconfluent.?Diquafosol (100 μl diluted 10%, 20%, or 30%) or 0.3% or 0.18% HA were added and incubated for 1, 6, or 24 h. DMEM (100 μl) was added to controls.?After 1, 6, and 24 h, plates were washed three times with PBS to remove the drugs.?Cell viabilities were evaluated after incubating for 24 h. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide;?thiazoyl blue (5 mg/mL) was then added to each well.?Samples were incubated in the dark for 4 h at 37℃, and media were then removed.?Precipitates were resuspended indimethyl sulfoxide (100 μl;?DMSO, Sigma-Aldrich).?Absorbances were measured on a plate reader at 570 nm.?The experiment was performed in triplicate[1].
动物实验: An SD rat dry eye model was used in which exorbital lacrimal gland extirpation decreased the Schirmer test score by at least 50%. After 8 weeks, when significant increases occurred in corneal epithelial permeability, Diquafosol tetrasodium(INS365)-containing eye drops were applied six times daily for the next 4 weeks at concentrations from 0.03% to 3.0%. Corneal barrier function was evaluated based on measurements with a modified anterior fluorometer of fluorescein penetrance at 1, 2, and 4 weeks after initial application. After INS365 application, the periodic acid-Schiff reagent (PAS)-stained area was evaluated in histologic sections of the tarsal and bulbar conjunctiva[2].
体外活性: duration of exposure and diquafosol concentration significantly reduced cell survival and increased cell lysis.?On the other hand, no significant difference was observed in HA groups regardless of exposure time.?Cell viability significantly decreased after treatment for 1 hour with 30% diluted diquafosol and after treatment for 6 hours with all diluted diquafosol.?After treatment with all diluted diquafosol for 24 hours, cell viability decreased and lysis increased, and significant cellular damage was observed[1].
体内活性: In a rat dry eye model, the P2Y(2) agonist INS365 was found to improve surface health, based on increases in tear fluid secretion, corneal epithelial resistance, and release of glycoprotein-containing moieties from goblet cells.??INS365 is a potential therapeutic agent for use in the treatment of dry eye syndrome[2].
