Sumario: | Micromeria biflora, a traditional medicinal plant, is extensively used for treating various painful conditions, such as nose bleeds, wounds, and sinusitis. A phytochemical investigation of the chloroform fraction of Micromeria biflora led to the isolation of salicylalazine. Salicylalazine was assessed in vivo for analgesia, muscle relaxation, sedative, and anti-inflammatory properties, as well as in vitro for COX-1/2 inhibition activities. It was assessed against a hot plate-induced model at different doses. The muscle relaxant potential of salicylalazine was evaluated in traction and inclined screening models, while sedative properties were determined using an open-field model. The anti-inflammatory potential of salicylalazine was assessed in histamine and carrageenan-induced paw edema screening models. Salicylalazine exhibited significant analgesic potential in a dose-dependent manner. In both screening models, an excellent time-dependent muscle-relaxation effect was observed. Salicylalazine demonstrated excellent sedation at high doses. Its anti-inflammatory activity was determined through the initial and late phases of edema. It exhibited anticancer potential against NCI-H226, HepG2, A498, and MDR2780AD cell lines. In vitro, salicylalazine showed preferential COX-2 inhibition (over COX-1) with an SI value of 4.85. It was less effective in the initial phase, while, in the later phase, it demonstrated significant effects at 15 and 20 mg/kg doses compared with the negative control. Salicylalazine did not exhibit cytotoxicity in the MTT assay, preliminarily indicating its safety. |
