The Sesquiterpene Lactone, Budlein A, Inhibits Antigen-Induced Arthritis in Mice: Role of NF-κB and Cytokines.
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by debilitating pain, cartilage destruction, and loss of joint function. Management of RA includes drugs that target NF-κB and downstream cytokine production. Therefore, molecules that act by inhibiting this signaling pathway without the severe side effects of, for instance, corticoids would be suitable therapeutic strategies. Budlein A is a sesquiterpene lactone with antinociceptive and anti-inflammatory properties related to the inhibition of pro-inflammatory cytokines and neutrophil recruitment. In this study, the effect of budlein A was evaluated in antigen-induced arthritis (AIA) in mice. At the 26th day, leukocyte recruitment to the knee joint, knee contents of proteoglycans, blood levels of ALT and AST, stomach tissue myeloperoxidase activity, and RT-qPCR for pro-inflammatory gene mRNA expression in knee joint samples was performed. NF-κB luciferase activity was evaluated in RAW 264.7 macrophages. Budlein A treatment dose-dependently inhibited AIA-induced mechanical hyperalgesia, edema, total leukocytes and neutrophil recruitment, and proteoglycan degradation. Budlein A did not induce gastric or liver damage. Budlein also inhibited AIA-induced Il-33, Tnf, Il-1β, preproET-1, and Cox-2 mRNA expression. In vitro, budlein reduced TNF- and IL-1β-induced NF-κB activity in RAW 264.7 macrophages. Altogether, we demonstrate that budlein A ameliorates AIA-induced inflammation and pain by targeting NF-κB. Importantly, budlein A does not induce in vivo side effects, suggesting that it possesses a favorable pre-clinical profile as analgesic and it is a prosperous molecule to be further investigated for the treatment of RA.

Anti-inflammatory and analgesic effects of the sesquiterpene lactone budlein A in mice: inhibition of cytokine production-dependent mechanism.
The anti-inflammatory activities of some medicinal plants are attributed to their contents of sesquiterpene lactones. In the present study, the anti-inflammatory and anti-nociceptive activity of a sesquiterpene lactone isolated from Viguiera robusta, budlein A in mice was investigated. The treatment with budlein A dose--(1.0-10.0 mg/kg, p.o., respectively) dependently inhibited the carrageenan-induced: i. neutrophil migration to the peritoneal cavity (2-52%), ii. neutrophil migration to the paw skin tissue (32-74%), iii. paw oedema (13-74%) and iv. mechanical hypernociception (2-58%) as well as the acetic acid-induced writhings (0-66%). Additionally, budlein A (10.0 mg/kg) treatment inhibited the mechanical hypernociception-induced by tumour necrosis factor (TNF-alpha, 36%), Keratinocyte-derived chemokine (KC, 37%) and Interleukin-1beta (IL-1beta, 28%), but not of prostaglandin E(2) or dopamine. Budlein A also inhibited the carrageenan-induced release of TNF-alpha (52%), KC (70%) and IL-1beta (59%). Furthermore, an 8 days treatment with budlein A inhibited Complete Freund's adjuvant (10 microl/paw)-induced hypernociception, paw oedema and paw skin myeloperoxidase activity increase while not affecting the motor performance or myeloperoxidase activity in the stomach. Concluding, the present data suggest that budlein A presents anti-inflammatory and antinociceptive property in mice by a mechanism dependent on inhibition of cytokines production. It supports the potential beneficial effect of orally administered budlein A in inflammatory diseases involving cytokine-mediated nociception, oedema and neutrophil migration.
