Swietenia humilis Zucc. (Meliaceae) seeds are used in Mexico for the treatment of type 2 diabetes mellitus. Mexicanolides are the main hypoglycemic and antihyperglycemic compounds of the species. This study was conducted to investigate the antihyperalgesic effect of an aqueous extract of the seeds of Swietenia humilis (SHAE) and of mexicanolide 2-hydroxy-destigloyl-6-deoxyswietenine acetate (1), using the formalin test in mice. The antihyperalgesic actions of SHAE and mexicanolide 1, as well as its possible transductional activity, were assessed in nicotinamide-streptozotocin (NA-STZ) hyperglycemic mice. Local injection of SHAE (10-177 mu g) and mexicanolide 1 (0.5-3.5 mu g) exhibited concentration-dependent antihyperalgesic action in NA-STZ hyperglycemic mice. Ketanserin (6 mu g), a 5-HT2A/C receptor antagonist, and flumazenil (6 mu g), a GABA(A) receptor antagonist, abolished the antihyperalgesic effect of mexicanolide 1 (3 mu g). On the other hand, naloxone (3 mu g), L-arginine (50 mu g), and N omega-Nitro-L-arginine methyl ester hydrochloride (150 mu g) diminished the antihyperalgesic effect of mexicanolide 1. The aqueous extract of the seeds possesses significant antihyperalgesic action. Compound 1 produces antihyperalgesia through GABA(A), 5-HT2A/C and opioid receptors. Also, the nitrergic system is involve in the antihyperalgesic effect of 1. Data obtained with Swietenia humilis Zucc. seeds give evidence of its potential for pain associated with diabetes treatment.
