“…Compared to other genotypes, PI 227687 caused the highest mortality and also possesses the highest concentration of the isoflavones genistin and daidzin (Carrão-Panizzi & Kitamura 1995, Piubelli 2000. Bioactivity of isoflavones in insects has been reported by Sutherland et al (1980) and Rao et al (1990) and it is likely that genistin and daidzein have a role in stink bug resistance. Trichomes were also mentioned as cause of nymph death by Panizzi (1991).…”

Actinobacteria - Basics and Biotechnological Applications

Actinobacteria, which share the characteristics of both bacteria and fungi, are widely distributed in both terrestrial and aquatic ecosystems, mainly in soil, where they play an essential role in recycling refractory biomaterials by decomposing complex mixtures of polymers in dead plants and animals and fungal materials. They are considered as the biotechnologically valuable bacteria that are exploited for its secondary metabolite production. Approximately, 10,000 bioactive metabolites are produced by Actinobacteria, which is 45% of all bioactive microbial metabolites discovered. Especially Streptomyces species produce industrially important microorganisms as they are a rich source of several useful bioactive natural products with potential applications. Though it has various applications, some Actinobacteria have its own negative effect against plants, animals, and humans. On this context, this chapter summarizes the general characteristics of Actinobacteria, its habitat, systematic classification, various biotechnological applications, and negative impact on plants and animals.

“…A convenient and readily applicable method for the synthesis of 3-benzoyl-7-hydroxy-6-nitroflavone (4) and 1-(2,4-dihydroxy-5-nitrophenyl)-3-phenyl-1,3-propanedione (5) intermediates has also been presented. 1 H-NMR spectra were recorded employing a Varian INOVA 400 NMR Spectrograph (Varian Inova Co. Ltd., USA) and chemical shifts (δ) are expressed in ppm relative to TMS used as internal standard. Infrared spectra were measured as KBr pellets with an FT/IR-430 spectrophotometer (JASCO Co. Ltd., Japan).…”

“…Synthesis of flavones and their derivatives have attracted considerable attention due to their significant biocidal [1][2][3], pharmaceutical [4][5][6][7] and antioxidant [8][9][10] activities. It has been observed that the presence of hydroxyl groups at position 5 or 7 is frequently required for higher biological activities [11,12].…”

A Novel Approach to the Synthesis of 6-Amino-7-hydroxy-flavone

et al. 2004

Abstract:A novel approach to the synthesis of 6-amino-7-hydroxyflavone (1) is described. Reaction in acetone of 2′,4′-dihydroxy-5′-nitroacetophenone and benzoyl chloride in the presence of potassium carbonate affords 3-benzoyl-7-hydroxy-6-nitroflavone, which is cleaved in 5% ethanolic potassium hydroxide to give 1-(2,4-dihydroxy-5-nitrophenyl)-3-phenyl-1,3-propanedione. The 1,3-diketone thus formed is then transformed into 7-hydroxy-6-nitroflavone, followed by reduction to afford the title compound.
