“…Recent studies have shown that p-cymene rich species, such as P. heptaphyllum (Aubl.) Marchand, Protium kleinii Cuatrec, (Burseraceae), Hyptis pectinata (L.) Poit, (Lamiaceae), and Zataria multiflora Boiss, (Lamiaceae), show antinociceptive activity in rodents (Bispo et al, 2011;Oliveira et al, 2005;Otuki et al, 2011;Ramezani et al, 2004;Santana et al, 2011).…”

Context: Several studies have demonstrated that essential oils and their major components have antioxidant activity. p-Cymene is a monoterpene and a major constituent of essential oils of various species of plants. Objective: This paper evaluated the antioxidant potential of p-cymene in the hippocampus of mice by determining the levels of thiobarbituric acid reactive substances (TBARS), nitrite content, and activity of catalase (CAT) and superoxide dismutase (SOD). Materials and methods: Swiss mice were intraperitoneally treated with 0.05% Tween 80 dissolved in 0.9% saline solution, ascorbic acid 250 mg/kg, and p-cymene at doses of 50, 100, and 150 mg/kg, respectively. After treatment, all groups were observed for 24 h, afterwards, the groups were euthanized for removal of the brain and dissection of the hippocampus. Results:The results of treatment with p-cymene were a significant decrease in lipid peroxidation and nitrite content at a dose of CYM 50: 65.54%, CYM 100: 73.29%, CYM 150: 89.83%, and CYM 50: 71.21%; CYM 100: 68.61% and CYM 150:67%, respectively, when compared with the control group. The results showed that at all tested doses, p-cymene produces an increase in SOD and catalase activity significantly at a dose of CYM 50: 22.7%, CYM 100: 33.9%, CYM 150: 63.1%, and CYM 50: 119.25%, CYM 100: 151.83% and CYM 150: 182.70%, respectively, when compared with the vehicle-treated group. Discussion and conclusion: The result of this study shows that p-cymene has an antioxidant potential in vivo and may act as a neuroprotective agent in the brain. This compound may present a new strategy in the development of treatment for many diseases in which oxidative stress plays an important pathophysiological role.

This study investigated the possible antinociceptive effect of p-cymene in different tests of orofacial nociception. The animals (mice) were pretreated (i.p.) with p-cymene (25, 50, 100 mg/kg), morphine (5 mg/kg), or vehicle (0.2% Tween 80+saline), and were then subsequently administered, subcutaneously into their upper lip: formalin, capsaicin, and glutamate. The nociceptive behavior response was characterized by the time in s that the mice remained rubbing the orofacial region, for a period of 40 min in the formalin test (first phase, 0-6 min; and second phase, 21-40 min), and for 42 and 15 min in the capsaicin and glutamate tests, respectively. To verify the possible opioid involvement in the antinociceptive effects, naloxone (i.p.) was administered into the mice 15 min prior to the pretreatment with p-cymene (100 mg/kg). Finally, whether or not the p-cymene evoked any change in motor performance in the Rota-rod test was evaluated. The results showed that the treatment with p-cymene, at all doses, reduced (p<0.001) the nociceptive behavior in all nociception tests. The antinociceptive effect of p-cymene was antagonized by naloxone (1.5 mg/kg). Additionally, mice treated with p-cymene did not show any change in motor performance. In conclusion, p-cymene attenuated orofacial nociception, suggesting an involvement of the opioid system in this effect. Thus, p-cymene might represent an important biomolecule for management and/or treatment of orofacial pain.

“…4,5 Protium kleinii Cuatrecas is endemic in southern Brazil, where it is known as "almecega", "almiscar", "pau-de-breu" and "guapoi", inter alia. 6 In an earlier paper 7 we reported the antinociceptive activity of the ether soluble portion and of 3β,16β-dihydroxy-urs-12-ene (brein) obtained from its resin.…”

Três triterpenos pentacíclicos inéditos foram isolados da resina de Protium kleinii. Suas estruturas, 3-oxo-11β,16β-diidróxi-urs-12-eno (1), 3-oxo-11β-hidróxi-urs-12-eno (2) e 3-oxo-11β-hidróxi-olean-12-eno (3), foram elucidadas por espectroscopia de RMN. A administração sistêmica destes compostos (10-100 mg kg -1 , i.p.) foi capaz de inibir tanto a primeira quanto a segunda fase da nocicepção induzida pela formalina em camundongos. Em adição, foram isolados os triterpenos conhecidos 3β,16β-dihidróxi-urs-12-eno (breina) (4) e uma mistura de α (5)-e β-amirina (6).Three novel pentacyclic triterpenes have been isolated from the resin of Protium kleinii and their structures elucidated by NMR spectroscopy as 3-oxo-11β,16β-dihydroxy-urs-12-ene (1), 3-oxo-11β-hydroxy-urs-12-ene (2) and 3-oxo-11β-hydroxy-olean-12-ene (3). The systemic administration of the above compounds (10-100 mg kg -1 , i.p.) was able to inhibited both first and second phase of the formalin-induced nociception in mice. The known triterpenes 3β,16β-dihydroxy-olean-12-ene (brein) (4) and a mixture of α (5)-and β-amyrin (6) were also found.
