A New Indole Alkaloid from the Toad Venom of Bufo bufo gargarizans.
A new indole alkaloid named bufobutarginine (1), along with three known bufotenines, namely, serotonin (2), bufotenidine (3), and bufotenine (4), were isolated from the water extract of toad venom. Their structures were elucidated by spectral methods. This is the first time that arginine has been found to be involved in the biosynthesis of bufotenines in parotid of toad. The cytotoxic activitie...
متن کاملPhylogeographic analysis of the Bufo gargarizans species complex: a revisit.
Using mtDNA sequencing and allozyme electrophoresis data, we tested the "vicariance followed by dispersal" hypothesis of the Bufo gargarizans species group and re-evaluated the species status in the general lineages species concept. A phylogenetic analysis suggested that dispersal, instead of vicariance, dominated the history of the species group. There was a general trend of west to east dispe...
متن کامل[Calcium-dependent chloride channels in plasma membrane of oocytes from toad, Bufo bufo gargarizans].
In this paper, membrane current properties of the fully-grown oocytes from toad, Bufo bufo gargarizans, were studied by using two-microelectrode voltage clamp technique. Axion of adult female toad was destroyed, and then ovarian lobes containing oocytes in stage I to VI were removed and incubated in Ca(2+)-free ND96 solution with collagenase (1.5 mg/ml) for 1 h. Subsequently, the oocytes were w...
متن کاملPancreatic endocrine cells in Bufo bufo: immunocytochemistry and ultrastructure.
The endocrine pancreas of the toad consists of rounded islets of various sizes embedded in the exocrine tissue. Isolated cells are also present. At least 4 types of endocrine cell are distinguishable by shape, size and electrondensity of the secretory granules as well as by their immunoreactivity with different antisera: insulin, somatostatin, pancreatic polypeptide, and glucagon cells. Insulin...
متن کاملOsmoregulation in red blood cells of Bufo viridis.
The effect of hyperosmotic solution of NaCl, urea and mannitol on Bufo viridis red blood cells were studied. The percentage of water content in B. viridis red blood cells decreased significantly in NaCl and mannitol hypertonic solutions compared to urea hypertonic solution. The urea concentration found in red blood cells in a urea hypertonic solution was significantly higher than in red blood c...
