Two series of novel fraxinellone-based thioethers containing 1,3,4-oxadiazole moiety were prepared as insecticidal agents against the oriental armyworm, Mythimna separata Walker. The structural assignment was based on the spectroscopic and X-ray analysis data. Among all the target compounds, compounds 4b, 4k, 5b, 5j and 5k exhibited more potent insecticidal activity with final mortality rates (...

The insecticidal activity of aqueous extract of Panax notoginseng (Burkill) F. H. Chen (Araliaceae) flower buds against Aedes albopictus Skuse (Diptera Culicidae) larvae and pupae was tested and quali-quantitative profile of principal saponins of the active tested aqueous extract were investigated by LC-ESI/MS/MS. P. notoginseng aqueous extract (35% of saponins/dried plant extract) showed the h...

In the current study, the stem wood of Millettia ovalifolia was evaluated for antifungal, insecticidal and phytotoxic activities. The results revealed that all the fractions showed no antibacterial activity against the tested bacterial strains. In case of antifungal activity, only ethyl acetate (EA) and chloroform (C) fractions exhibited minimum inhibitory concentration both at 500 μg/ml agains...

Ekino et al. [1] reported the cloning and characterization of a novel cytotoxic protein (Parasporin-5) produced by Bacillus thuringiensis strain A1100. The 33.8-kDa inactive precursor protein exhibited strong cytocidal activity upon proteinase K activation against several mammalian (cancer) cell lines, and showed slight homology with Cry and aerolysin-type β-pore-forming toxins. Most research c...

Twenty spirodiclofen analogues have been designed and conveniently synthesized via three steps including esterification, one-pot heterocyclization, and acylation reactions. The target molecules have been identified on the basis of analytical spectra (H NMR, C NMR and ESI-MS) data. All newly synthesized compounds have been screened for their potential insecticidal and herbicidal activity by stan...

In this study, antibacterial, antifungal, antimycobacterial, cytotoxic, antitumor, cardiovascular, antifeedant, insecticidal, antileishmanial and some other single activities of diterpenoids and norditerpenoids isolated from Turkish Lamiaceae plants, are reviewed. The diterpenoids were isolated from species of Salvia, Sideritis, and Ballota species growing in Anatolia. Fifty abietanes, ten kaur...

Abstract The present work aimed to determine the insecticidal effects of three selected essential oils (EOs) Pogostemon cablin , Thymus vulgaris and Citrus aurantifolia against insect species Melolontha melolontha Halyomorpha halys Pyrrhocoris apterus . EO P. showed very strong M. when it inhibited by more than 50% at concentrations 50–6.25%. Against H. also 50–12.5%. activity was significantly...
