Resumo

Objective To examine whether free (3-PD-5(free)) and/or liposomal (3-PD-5(lipo)) 6,7-dihydroxy-3-{[}3 `,4 `-methylenedioxyphenyl]-coumarin (3-PD-5) (1) modulate the effector functions of neutrophils from patients with rheumatoid arthritis under remission (i-RA) and with active disease (a-RA), in vitro; and (2) exert anti-inflammatory effect in a rat model of zymosan-induced acute joint inflammation. Methods and results Incorporation of 3-PD-5 into unilamellar liposomes of soya phosphatidylcholine and cholesterol was efficient (57.5 +/- 7.9%) and yielded vesicles with low diameter (133.7 +/- 18.4 nm), polydispersity index (0.39 +/- 0.06), and zeta potential (- 1.22 +/- 0.34 mV). 3-PD-5(free) (1 mu M) and 3-PD-5(lipo) (3 mu M) equally suppressed elastase release and reactive oxygen species generation in neutrophils from healthy subjects and i-RA and a-RA patients, stimulated with immune complexes. 3-PD-5(free) (20 mu M) suppressed the release of neutrophil extracellular traps and chemotaxis in vitro, without clear signs of cytotoxicity. 3-PD-5(lipo) (1.5 mg/kg, i.p.) diminished joint edema and synovial infiltration of total leukocytes and neutrophils, without changing the synovial levels of TNF-alpha, IL-1 beta, and IL-6. Conclusion Altogether, the results reported herein indicate that 3-PD-5 is a promising modulator of the early stages of acute joint inflammation that can help to diminish not only excessive neutrophil infiltration in the synovia but also neutrophil activation and its outcomes in RA patients.
