Purity: ≥98%
Triamcinolone acetonide (Acetospan; Adcortyl A; AllerNaze; Kenalone; Nasacort; Aristocort; Aristoderm. Aristogel) is a potent and synthetic glucocorticoid with improved anti-inflammatory activities.
ln Vitro |
As the concentration rises, triamcinolone acetonide (0.05-3 mg/mL, 48-60 h) decreases BRECs' capacity to proliferate [1]. In a concentration-dependent manner, triamcinolone acetonide (0.04-5 mg/mL, 24 h) decreases the viability of both normal and osteoarthritic (OA) chondrocytes [2]. The degree of cartilage structural degradation, chondrocyte loss and colony formation, and proteoglycan loss in OA cartilage are all made worse by triamcinolone acetonide (0.04-5 mg/mL, 24 h) [2]. Strongly inducing monocyte differentiation toward M2 and anti-inflammatory macrophage phenotypes is triamcinolone acetonide (100 nM, 7 days) [3].

ln Vivo |
In rats with osteoarthritis, intraperitoneal injection of 1.43 mg/mL triamcinolone acetonide once a week for 6–12 weeks totally stops the development of osteophytes and improves FRβ-related macrophage activation [3].

Cell Assay |
Cell Viability Assay[2]
Cell Types: Chondrocyte Tested Concentrations: 0.04, 0.08, 0.16, 0.31, 0.63, 1.25, 2.5, and 5 mg/ml Incubation Duration: 24 h Experimental Results: decreased cell viability with the value of IC50 was 2.23 mg/ mL in normal chondrocytes and 1.14 mg/mL in OA chondrocytes. |
Animal Protocol |
Animal/Disease Models: Severe OA rat model [3]
Doses: 1.43 mg/mL Route of Administration: intraperitoneal (ip)injection Experimental Results: diminished body weight during OA induction. demonstrated more macrophage activation and minimal or no osteophyte formation when injected knee joints. |

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.79 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 (4.79 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in 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 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*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.
