Pyrintegrin, a β1-integrin agonist, is a potent and cell-permeable promoter of the adhesion of individually dissociated hESCs on matrigel- or laminin-, but not gelatin-coated surfaces, substantially reducing trypsinization-induced apoptosis.
ln Vitro |
In a dose-dependent manner (IC50 of 1.14 μM), pyrintegrin (0-10 μM; 1 hour; hASC) administration suppresses BMP4-mediated phosphorylation of BMP-responsive SMAD1/5 [1]. Pyrintegrin induces human adipose stem/progenitor cells (hASC) to differentiate into lipid adipocytes in vitro by upregulating CCAAT/enhancer binding protein-α (C/EBPα) and peroxisome proliferator-activated receptor (PPARγ). Additionally, the secretion of adiponectin, leptin, glycerol, and total triglycerides increases in differentiated cells. By phosphorylating SMAD1/5 through BMP, pyrintegrin reduces Runx2 and Osx [1]. In cultured cells, pyrintegrin administration reduces injury-induced declines in focal adhesions, F-actin stress fibers, and active β1-integrin levels [2]. Western blot examination

ln Vivo |
Pyrintegrin (10 mg/kg; i.p.; once; C57BL/6J mice) treatment protected mice from LPS-induced podocyte foot process effacement and proteinuria. Analysis of mouse glomeruli showed that LPS administration reduced active β1 integrin levels in podocytes, and co-treatment with Pyrintegrin prevented this [2]. ? In rats, Pyrintegrin reduces peak proteinuria caused by puromycin aminonucleoside-induced nephropathy [2]. ? Pyrintegrin induces transplanted adipose stem/progenitor cells (ASCs) and recruits endogenous cells to form postnatal adipose tissue in vivo. In vivo, Pyrintegrin-treated human adipose stem/progenitor cells (ASCs) in 3D bioprinted scaffolds generated ectopically formed adipose tissue expressing human PPARγ when transplanted into the back of athymic mice. Notably, Pyrintegrin-adsorbed collagen gel implanted in the inguinal fat pad promoted adipogenesis formed by host endogenous cells, demonstrating its ability to induce in situ adipogenesis without the need for cell transplantation [1].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.61 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (4.61 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
