“…(2011). High polymorphism revealed that RAPD could resolve genetic variation among crop germplasm, identification of cultivars and for estimating genetic relationship (Silva et al., 2005a;2005b). In this present study, RAPD markers revealed 55.19% of polymorphism loci in Ae.pop 1 and 40.09% in Tri.pop 6 .…”

“…Phytoalexins (including terpenoids, glycosteroids, flavonoids and polyphenols) are small molecules (molecular weight < 500) which are both synthesized and accumulated in the plant after the recognition of elicitors derived from exposure to attackers [9]. Besides improving protection against both biotic and abiotic stresses, secondary metabolites are an important source of anticancer, antioxidant, antidiabetic, immunosuppressive, antifungal, anti-inflammatory, antimalarial, anti-oomycete, antibacterial, antifever, antidiabetic, insecticidal, nematicidal, and antiviral agents [10,11,12].…”

New Perspectives on the Use of Phytochemicals as an Emergent Strategy to Control Bacterial Infections Including Biofilms

et al. 2016

Abstract:The majority of current infectious diseases are almost untreatable by conventional antibiotic therapy given the advent of multidrug-resistant bacteria. The degree of severity and the persistence of infections are worsened when microorganisms form biofilms. Therefore, efforts are being applied to develop new drugs not as vulnerable as the current ones to bacterial resistance mechanisms, and also able to target bacteria in biofilms. Natural products, especially those obtained from plants, have proven to be outstanding compounds with unique properties, making them perfect candidates for these much-needed therapeutics. This review presents the current knowledge on the potentialities of plant products as antibiotic adjuvants to restore the therapeutic activity of drugs. Further, the difficulties associated with the use of the existing antibiotics in the treatment of biofilm-related infections are described. To counteract the biofilm resistance problems, innovative strategies are suggested based on literature data. Among the proposed strategies, the use of phytochemicals to inhibit or eradicate biofilms is highlighted. An overview on the use of phytochemicals to interfere with bacterial quorum sensing (QS) signaling pathways and underlying phenotypes is provided. The use of phytochemicals as chelating agents and efflux pump inhibitors is also reviewed.

“…Asteraceae are important for their recognized insecticidal activity described in the literature [34, 35]. Alkalamides and coumarins showed insecticidal activity against Sitophylus oryzae and Rhyzopertha dominica [36], polyacetylenes and terpenes have proven insecticide and repellent activities against larvae and adults of A. aegypti [37–39].…”

AbstractAyapana triplinervis is a plant species used in traditional medicine and in mystical-religious rituals by traditional communities in the Amazon. The aim of this study is to evaluate the larvicidal activity against A. aegypti of nano-emulsions containing essential oils from A. triplinervis morphotypes, and acute oral toxicity in non-target organism. Essential oils were identified and nano-emulsions were prepared using the low energy method. The mortality test of A. aegypti larvae was performed according to the protocol recommended by the World Health Organization, and toxicity in non-target mammals was performed according to the OECD. Phytochemical analyses indicated the major compounds (E)-Caryophyllene (45.93%) and Thymohydroquinone Dimethyl Ether (32.93%) in morphotype A, and in morphotype B, Thymohydroquinone Dimethyl Ether (84.53%) was found. Morphotype A essential oil nano-emulsion showed a particle size of 101.400 ± 0.971 nm (PdI = 0.124 ± 0.009 and ZP = −19,300 ± 0.787 mV). Morphotype B essential oil nano-emulsion had a particle size of 104.567 ± 0.416 nm (PdI = 0.168 ± 0.016 and ZP = −27,700 ± 1,307 mV). Histomorphological analyses showed the presence of inflammatory cells in the liver of animals treated with morphotype A essential oil nano-emulsion (MAEON) and morphotype B essential oil nano-emulsion (MBEON). Congestion and the presence of transudate with leukocyte infiltration in the lung of animals treated with MAEON were observed. The nano-emulsions containing essential oils of A. triplinervis morphotypes showed an effective nanobiotechnological product in the chemical control of A. aegypti larvae and safe for non-target mammals.
