Novel ocellatin peptides mitigate LPS-induced ROS formation and NF-kB activatio...
Sousa, Nayara A.; Oliveira, Guilherme A. L.; de Oliveira, Ana Patrícia; Lopes, André Luís F.; Iles, Bruno; Nogueira, Kerolayne M.; Araújo, Thiago S. L.Cutaneous secretions of amphibians have bioactive compounds, such as peptides, with potential for biotechnological applications. Therefore, this study aimed to determine the primary structure and investigate peptides obtained from the cutaneous secretions of the amphibian, Leptodactylus vastus, as a source of bioactive molecules. The peptides obtained possessed the amino acid sequences, GVVDILKGAAKDLAGH and GVV...
Lactobacillus reuteri DSM 17938 protects agains gastric damage induced by ethan...
Oliveira, Ana P.; Souza, Luan K. M.; Araújo, Thiago S. L.; Araújo, Simone de; Nogueira, Kerolayne M.; Sousa, Francisca Beatriz M.; Silva, Renan O.This study aimed to evaluate the effect of Lactobacillus reuteri DSM 17938 (DSM) on ethanol-induced gastric injury, and if its possible mechanism of action is related to inhibiting the transient receptor potential vanilloid type 1 (TRPV1). We evaluated the effect of supplementing 108 CFU g body wt1 day1 of DSM on ethanol-induced gastric injury. DSM significantly reduced the ulcer area (1.940 1.121 mm2) with 3 d...
Epiisopiloturine hydrochloride, an imidazole alkaloid isolated from Pilocarpus ...
Nicolau, Lucas Antonio Duarte; Carvalho, Nathalia S.; Pacífico, Dvison M.; Lucetti, Larisse T.; Aragão, Karoline Sabóia; Véras, Leiz M.C.Objective This study aimed to investigate the protective effect of epiisopiloturine hydrochloride (EPI), an imidazole alkaloid, on NAP-induced gastrointestinal damage in rats. Methods Initially, rats were pretreated with 0.5% carboxymethylcellulose (vehicle) or EPI (3, 10 and 30 mg/kg, p.o. or i.p., groups 3–5, respectively) twice daily, for 2 days. After 1 h, NAP (80 mg/kg, p.o.) was given. The control group r...
Anti-inflammatory effect of the monoterpene myrtenol is dependent on the direct...
Gomes, Bruno S.; S. Neto, Benedito P.; Lopes, Everton M.; Cunha, Francisco V. M.; Araújo, Alyne R.; Wanderley, Carlos W. S.; Wong, Deysi V. T.Myrtenol is a bicyclic monoterpene with anti-in fl ammatory properties. However, the mechanisms involved are partially unknown. Here, we investigated the effect of myrtenol during experimental chronic arthritis and the possible modulating activity of oxidative stress and neutrophil migration. Complete Freund's Adjuvant (CFA)-sensitized rats were treated with vehicle (1 mL/kg, po), myrtenol (12.5, 25 or 50 mg/kg...
Phytol, a diterpene alcohol, inhibits the inflammatory response by reducing cyt...
Silva, Renan O.; Sousa, Francisca Beatriz M.; Damasceno, Samara Rodrigues Bonfim; Carvalho, Nathalia S.; Silva, Valdelânia G.Studies have shown that diterpenes have anti-inflammatory and redox-protective pharmacological activities. The present study aimed to investigate the anti-inflammatory properties of phytol, a diterpene alcohol, in a mouse model of acute inflammation, and phytol effect on leukocyte recruitment, cytokines levels, and oxidative stress. The anti-inflammatory activities of phytol were assessed by measuring paw edema...
