Arthritis is a chronic disease that affects approximately 1% of the global population. The main therapies available for this condition have a high risk of failure and advanced treatments are limited and expensive. In this study, nanomicelles of a plant-derived compound called Methyl gallate (MG) were formulated and evaluated for their effectiveness in a mice model of arthritis. The nanomicelles showed promising results in reducing inflammation and cell count at the inflammation site. These findings suggest that MG nanomicelles could be a potential alternative treatment for arthritis.
Arthritis is a chronic disease that affects, approximately, 1 % of the total global population. It is characterized by chronic inflammation, accompanied in most of the cases of motor disability and sever pain. The main therapies available have high risk of failure and advanced treatments are scarce and highly cost. In this scenario, search for effective, safe and low-cost treatments is quite desirable. Methyl gallate (MG) is a plant-derived phenolic compound described to present remarkable anti-inflammatory effect in experimental models of arthritis. Thus, in this study we formulated nanomicelles of MG using Pluronic (F-127) as matrix and evaluated in vivo the pharmacokinetic, biodistribution and its effect in the mice model of zymosan-induced arthritis. The nanomicelles were formed with a size 126 nm. The biodistribution showed a ubiquitous tissue deposition with a renal excretion. The pharmacokinetics showed elimination half-life of 1.72 h and a clearance of 0.006 L/h. The oral pretreatment with nanomicelles containing MG (3.5 or 7 mg/kg) demonstrated a reduction in total leukocytes, neutrophils, and mononuclear cells from the inflammation site. The data supports the use of methyl gallate nanomicelles as an alternative drug for arthritis.Data availability: All the data of this study are transparent.
