Kainate receptors show a particular affinity for a variety of natural source compounds, including dysiherbaine (DH), a potent agonist derived from the marine sponge Dysidea herbacea. In this study, we characterized the pharmacological activity and structural basis for subunit selectivity of neodysiherbaine (neoDH) and MSVIII-19, which are natural and synthetic analogs of DH, respectively. NeoDH...
Antagonists for kainate receptors (KARs), a family of glutamategated ion channels, are efficacious in a number of animal models of neuropathologies, including epilepsy, migraine pain, and anxiety. To produce molecules with novel selectivities for kainate receptors, we generated three sets of analogs related to the natural marine convulsant neodysiherbaine (neoDH), and we characterized their pha...
Ephedra intermedia (Schrenket) is a medicinal plant belong to family Ephedraceae from Gnetales, order of gymnosperms. Shoot explants of E. intermedia were cultured in MS medium with some treatments of auxin (indole acetic acid=IAA) include 2.5, 5, 10 and 15mgl-1 supplemented with Kinetin (Kin) include 2.5, 5, 10 and 20 mgl-1. The powder of E. intermedia dry organs and in vitro auxin and Kinetin...
Supercritical fluid extraction was used to extract the alkaloid N-[7-(3',4'-methylenedioxyphenyl)-2(Z),4(Z)-heptadienoyl]pyrrolidine from leaves of Piper amalago L. A three-level orthogonal array design matrix, OAD OA9(34), was used for optimization of the parameters of supercritical extraction of the alkaloid, employing supercritical carbon dioxide: extraction time (20, 40, and 60 min), temper...
