SB-273005
Based on 1 Customer Validation
SB-273005 is an orally active non-peptide αvβ3 integrin antagonist with Ki values of 1.2 nM and 0.3 nM for αvβ3 and αvβ5, respectively. SB-273005 blocks the binding of integrins to the RGD sequence in the extracellular matrix. SB-273005 inhibits Rictor phosphorylation and reduces IL-10 secretion. SB-273005 inhibits inflammation, prevents bone loss, regulates vascular smooth muscle function, and reverses pregnancy-induced immune deviation. SB-273005 can be used in the study of rheumatoid arthritis, osteoporosis, and aneurysms. .

SB-273005 (0.1 nM-1 µM; 1 h) dose-dependently inhibits adhesion of mouse and monkey VSMCs to vitronectin-coated plates, with similar IC50 values (2.9 nM for mouse, 6.9 nM for monkey)[2].
SB-273005 (100 nM-100 µM) inhibits TGFβ-induced Rictor phosphorylation and VSMC migration in mouse aortic smooth muscle cells[3].

SB-273005 (300-1000 mg/kg; p.o.; daily; 3-14 days) causes acute aortic and renal artery smooth muscle cell necrosis, followed by medial hypertrophy and fibrosis in CD-1 mice[2].
SB-273005 (3 mg/kg; p.o.; during days 3-5 of pregnancy) reduces splenic Th2 cell polarization and IL-10 secretion, reversing pregnancy-induced immune deviation in pregnant mice[4].
SB-273005 (3-30 mg/kg; p.o.; once daily; 8 days) decreases urinary deoxypyridinoline (bone resorption marker) and preserves trabecular bone density in Thyroxine-induced osteopenic rats[5].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.54 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.54 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
