Naturally occurring homoisoflavonoids and their pharmacological activities.
Homoisoflavonoids, a special subclass of flavonoids, are rarely found in nature, mainly existing in Fabaceae and Asparagaceae families and being less common in Polygonaceae, Portulacaceae, Orchidaceae, and Gentianaceae families. Until now, approximately 240 natural occurring homoisoflavonoids have been identified from roots, barks, heartwood, bulbs, leaves, and seeds of the plants from the abov...
متن کاملAsymmetric synthesis of naturally occurring spiroketals.
Spiroketals are widely found as substructures of many naturally occurring compounds from diverse sources including plants, animals as well as microbes. Naturally occurring spiroketals are biologically active and most of them are chiral molecules. This article aims at reviewing the asymmetric synthesis of biologically active spiroketals for last 10 years (1998-2007).
متن کاملFirst total synthesis of antiostatin A1, a potent carbazole-based naturally occurring antioxidant.
The first total synthesis of the potent antioxidant antiostatin A1 is reported, where its key features rely on a chemo- and regioselective rhodium-catalysed crossed alkyne cyclotrimerisation reaction applying functionalised ynamides and a palladium-catalysed arylamidation reaction.
متن کاملFirst Total Synthesis of a Naturally Occurring Iodinated 5′-Deoxyxylofuranosyl Marine Nucleoside
4-Amino-7-(5'-deoxy-β-D-xylofuranosyl)-5-iodo-pyrrolo[2,3-d]pyrimidine 1, an unusual naturally occurring marine nucleoside isolated from an ascidan, Diplosoma sp., was synthesized from D-xylose in seven steps with 28% overall yield on 10 g scale. The key step was Vorbrüggen glycosylation of 5-iodo-pyrrolo[2,3-d]pyrimidine with 5-deoxy-1,2-O-diacetyl-3-O-benzoyl-D-xylofuranose. Its absolute conf...
متن کاملNaturally occurring ehrlichiosis in Egyptian dogs
Canine ehrlichiosis has emerged as one of the most clinically important tick-borne diseases affecting dogs. Eighty-five naturally infected dogs have been investigated, the most consistent clinical signs recorded were fever, emaciation and lymphoadenopathy, anemia, monocytosis, thrompocytopenia, hypoalbuminemia, elevation in liver enzymes and total bilirubin were the most remarkable changes asso...
