The Diels-Alder reaction is one of the most common methods to chemically synthesize a six-membered carbocycle. While it has long been speculated that the cyclohexene moiety found in many secondary metabolites is also introduced via similar chemistry, the enzyme SpnF involved in the biosynthesis of the insecticide spinosyn A in Saccharopolyspora spinosa is the first enzyme for which catalysis of...

The taxonomic status of a marine actinomycete isolated from the sponge Haliclona sp. collected from Cebu, Philippines, was established using both phenotypic and genotypic data. Strain SPE 10-1(T) exhibited chemotaxonomic and morphological characteristics that were consistent with those of members of the genus Saccharopolyspora. It showed a strict requirement for salt and is the first obligate m...

BACKGROUND/AIM To determine the phenolic acid levels and DNA damage protection potential of Capparis spinosa L. seed extract and to investigate the effect of the extract on cognitive impairment and oxidative stress in an Alzheimer disease mice model. MATERIALS AND METHODS Thirty BALB/c mice divided into 5 groups (control, D-galactose, D-galactose + C. spinosa 50, D-galactose + C. spinosa 100,...

Saccharopolyspora erythraea is a Gram-positive bacterium that can produce antibiotics. However, this microorganism must often be genetically improved for higher production before it can be used in an industrial setting. Here, we report the whole-genome sequence of the industrial hyperproducer strong mutator Saccharopolyspora erythraea strain D.

Spinosad (a mixture of spinosyns A and D, Fig. 1) is a new and highly promising insecticide, derived from the bacteria Saccharopolyspora spinosa, with efficacy against a wide range of insects. The mechanism of action of spinosad appears to be unique, with a primary site of attack being the nicotinic acetylcholine receptor (nAChR) and a secondary site of attack being g-aminobutyric acid (GABA) r...

Pycnocycla spinosa Decne. ex Boiss. var. spinosa (Fam. Umbelliferae) is an essential oil-containing wild plant growing in central part of Iran. Hydroalcoholic extract of Pycnocycla spinosa has antispasmodic and antidiarrheal activity. The aim of this study was to further investigate antidiarrheal and small intestinal transit effect of P. spinosa extract for a comparison with loperamide and dicy...

Bioassay monitoring of hydroalcoholic extract from the aerial part of Pyconcycla spinosa revealed that it contains components with spasmolytic activity in vitro. In addition, P. spinosa extract at oral dose of 1-5 mg/kg inhibits diarrhoea in animal models. Pharmacological screening of pure compounds isolated from P. spinosa hydroalcoholic extract led to the identification of 3,7,10,14,15-pentaa...

Introgression may lead to discordant patterns of variation among loci and traits. For example, previous phylogeographic studies on the genus Quasipaa detected signs of genetic introgression from genetically and morphologically divergent Quasipaa shini or Quasipaa spinosa. In this study, we used mitochondrial and nuclear DNA sequence data to verify the widespread introgressive hybridization in t...
