Item Acesso aberto (Open Access) Ação antimicrobiana do óleo essencial de Piper Aduncum e dilapiol em infecções de pele(Universidade Federal do Pará, 2015-06-25) FERREIRA, Roseane Guimarães; MAIA, José Guilherme Soares; http://lattes.cnpq.br/1034534634988402Piper aduncum L. is a plant with several biological properties such as antimicrobial activity, which is mainly associated with the action of its essential oil rich in dilapiolle. In recent years, the occurrence of skin infections caused by bacteria and fungi increased considered shape. Thus, this study aimed to evaluate the antimicrobial activity of essential oil of P. aduncum (OEPA) and dilapiolle, its major constituent, against pathogenic skin micro-organisms and their attachments. The antimicrobial activity was performed using the microdilution method and Forming Units count Cologne (UFC) for determining the Minimum Inhibitory Concentration (MIC), the Bactericidal Concentration Minimum (CBM) and Minimum Fungicidal Concentration (CFM). These plant compounds were tested against the filamentous fungi dermatophytes (FFD) and not dermatophyte (FFND), gram-positive bacteria and yeast. The results showed Trichophyton mentagrophytes front (ATCC and clinical isolate), MIC values of 500μg.mL-1 for OEPA and dilapiolle and CFM 1500 and 1000 µg.mL-1 , respectively. For clinical isolates of Trichophyton rubrum and Epidermophyton floccosum the MIC values of 500μg.mL-1 and CFM 1500μg.mL-1 , were similar for the two compounds as well as Microsporum canis and Microsporum gypseum with MIC values of 250μg.mL-1 and CFM 500μg.mL-1 . The Aspergillus fumigatus ATCC FFND showed an MIC of 3.9μg.mL-1 and 7.8 μg.mL-1 and the clinical isolate strain MIC of 3.9μg.mL-1 and CFM 15.6 μg.mL-1 for both. However showed no activity against Candida albicans and the yeast bacteria Staphylococcus aureus in the concentrations used.Item Acesso aberto (Open Access) Atividade anticolinesterásica dos óleos essenciais e componentes majoritários de Piper spp e Aniba canelilla e docagem molecular do 1-nitro-2-feniletano(Universidade Federal do Pará, 2013-05-28) SILVA, Nayla Nunes dos Santos; ANDRADE, Eloisa Helena de Aguiar; http://lattes.cnpq.br/3827055876022373; MAIA, José Guilherme Soares; http://lattes.cnpq.br/1034534634988402Currently, Alzheimer's disease (AD) is considered a significant public health problem worldwide and the major complication of the disease is the deficit of cholinergic neuron activity, a fact that can be reversed and/or mitigated by raising levels of the neurotransmitter acetylcholine (ACh). The most effective way to increase the available amount of acetylcholine is the inhibition of the acetylcholinesterase enzyme (AChE). In the search for new natural cholinesterasic inhibitors, the essential oils and major components of five aromatic plants occurring in the Amazon region were investigated using the AChE inhibition test by direct bioautography. The oils and major components were obtained from Aniba canelilla (1-nitro-2-phenylethane), P. aduncum (dillapiole), P. callosum (safrole), P. divaricatum (methyleugenol) and P. marginatum (safrole+3,4-methylenedioxipropiophenone). The oils of A. canelilla and P. aduncum showed enzyme inhibition zone in amounts of 0.01 ng and 1ng, respectively. The oil of P.marginatum showed weak activity (~ 100 ng) and the oils of P. callosum and P. divaricatum were inactive. Among the major constituents, who showed activity are the phenylpropanoids 1-nitro-2-phenylethane, isolated from the oil of A. canelilla, and safrole and elemicin, isolated from the oil of P. callosum, which inhibited the AChE in amounts of 0.01, 1000 to 1000 ng, respectively. The results indicate that the oil of A. canelilla and 1-nitro-2-phenylethane inhibited AChE in the same proportion as the pattern physostigmine. The molecular docking study was added to the experimental results, showing that the nitro group of 1-nitro-2-phenylethane can establish hydrogen bonds with the hydroxyl group of the serine residue existing in the catalytic AChE molecule, suggesting that the electronegative character of 1-nitro-2-phenylethane may be responsible for this strong chemical interaction.Item Acesso aberto (Open Access) Avaliação da atividade antiplasmódica in vitro dos óleos de Andiroba (Carapa guianensis Aubl.) e Pimenta-de-macaco (Piper aduncum L)(Universidade Federal do Pará, 2010) MIRANDA JUNIOR, Raimundo Nonato Cardoso; DOLABELA, Maria Fâni; http://lattes.cnpq.br/0458080121943649; MAIA, José Guilherme Soares; http://lattes.cnpq.br/1034534634988402In search of new antimalarial drugs, two typical species of the Amazon region and a fraction rich limonoids were the object of this study: Carapa guianensis Aubl. (Meliaceae), known popularly as andiroba traditionally used as an insecticide and fighting malaria, the species Piper aduncum L. (Piperaceae), known popularly as the pimento-de-macaco, used to treat inflammatory diseases and the fraction rich limonoids obtained from Carapa guianensis. Crude oil and fraction were tested in vitro using methods described by Rieckman and col. (1980) modified by Carvalho (1990) with Plasmodium falciparum clones W2 and Dd2. These studies showed that the oils had antiplasmodial activity, with a concentration of 0.82ng/mL and 8.2mg/mL andiroba oil showed an inhibition he W2 clone was 100% and Dd2 to 71% (IC50 9.4 μg/ml) after 72h of exposure respectively. For the fraction at a concentration of 3.1mg/mL, clone W2, was 100% and Dd2 to 82% (IC50 0.4 μg/ml), after 72h of exposure. The pimento-de-macaco oil overalls had a concentration of 1.30ng/mL for the W2 clone inhibition of 100% and the Dd2 to 77% after 72h of exposure to a concentration of 10.3mg/mL. The results with the chili oil overalls at a concentration of 1.30ng/ml the inhibition was 100% in clone W2 and Dd2 clone at a concentration of 10.3mg/mL, inhibition was 77% after 72h of exposure.Item Acesso aberto (Open Access) Avaliação da composição química e atividades biológicas dos óleos essenciais de Lippia gracilis e Lippia origanoides da Amazônia oriental(Universidade Federal do Pará, 2012-10-17) FRANCO, Caroline da Silva; SILVA, Joyce Kelly do Rosário da; http://lattes.cnpq.br/2278686174214080; MAIA, José Guilherme Soares; http://lattes.cnpq.br/1034534634988402The genus Lippia is known for its aromatic character and medicinal use of its species as an alternative therapy. Essential oils of Lippia gracilis and L. origanoides collected in Pará and Maranhão were obtained by hydrodistillation and were rich in monoterpenes. The major compounds oil of L. gracilis were thymol (72.5%), p-cymene (9.3%) and thymol methyl ether (5.4%); for oil of L. origanoides were thymol (45.8%), p-cymene (14.3%), -terpinene (10.5%) and carvacrol (9.9%). The oils had potential larvicide against Artemia salina with LC50 values of 7.4 ± 0,2 μg.mL-1 to L. origanoides and 18.7 ± 0.2 μg.mL-1 to L. gracilis, both more active than lapachol (EC50 = 21.2 ± 2.2 μg/ ml). The essential oil of L. gracilis showed moderate scavenging capacity DPPH with EC50 value = 35.7 ± 3.32 μg.mL-1 about 8 times less active than the standard trolox (EC50 of 4.5 ± 0.1). Furthermore, the oil L. gracilis proved to be a good natural fungicide against the phytopathogen C. sphaerospermum with limit of detection of 5 μg, about 10 times less active than miconazole (DL = 0.5 μg). Moreover, the oil L. origanoides no showed significant activity (DL = 100μg).Item Acesso aberto (Open Access) Óleos essenciais ricos em linalol (Aniba Rosaeodora, A. Parviflora e Aeollanthus Suaveolens) na Amazônia e seus efeitos neurocomportamentais em roedores(Universidade Federal do Pará, 2017-06-28) SANTOS, Everton Renan Quaresma dos; MAIA, Cristiane do Socorro Ferraz; http://lattes.cnpq.br/4835820645258101; MAIA, José Guilherme Soares; http://lattes.cnpq.br/1034534634988402Essential oils from the Amazon, rich in linalool (Aniba rosaeodora Ducke, rosewood; A. parviflora (Meisn.) Mez, macacaporanga; and Aeollanthus suaveolens Mart. Ex Spreng, catinga-de-mulata), are capable of interacting with the central nervous system (CNS). The objective of this work was to evaluate the neurobehavioral effects of these oils in rodents. The oils were extracted and analyzed for their chemical composition, where the main constituent was linalool (rosewood, 88.6%; macacaporanga, 45%; and catinga-de-mulata, 49.3%). Linalool is an oxygenated monoterpene commonly found in various essential oils used in perfumes and fragrances. The Male Wistar rats received by intraperitoneal the oils of rosewood (doses of 3.5 and 35 mg/kg), macacaporanga (doses of 8.5 and 85 mg/kg), catinga-de-mulata (doses of 7, 5 and 75 mg/kg) and the linalool standard (30 mg/kg). The oils and linalool were administered 30 minutes prior to testing. Afterwards, the animals were evaluated in the open field tests, high cross labyrinth, splash, forced swimming and inhibitory avoidance. The results showed that rosewood, macacaporanga, and catinga-de-mulata oils (at the highest dose administered), as well as the standard linalool, have antidepressant-type activity. In the splash test, there was a significant reduction in latency to initiate self-cleaning behavior and the increase self-cleaning time, except for macacaporanga oil, in this last parameter. In the forced swim test, there was a significant reduction in the immobility time of the animals. The oils tested showed antidepressant activity due to the presence of linalool, without interfering with spontaneous locomotion and memory formation.
