Grayanotoxins

The lipid-soluble toxins (veratridine, batrachotoxin, aconitine, grayanotoxins). These toxins cause persistent activation of Na channels, i.e., their permanent opening and hence membrane depolarization 56-58). [Pg.194]

On the side, this causes me to wonder if the diterpenoid toxins of Rhododendrons, known as grayanotoxins, which mimic the physiologic effects of ciguatoxins, also chelate metal cations. [Pg.71]

Grayanotoxins.—Pieris japonica (Ericaceae) contains a number of diterpenoid toxins. An X-ray analysis of pieristoxin G (100) has been published and the structures (101)—(103) have been assigned to asebotoxins VI, VIII, and IX respectively. [Pg.139]

The Williams approach to bicyclo[5.4.0]undecane containing molecules such as the cyathins, striatins, dolastanes, clavularanes, grayanotoxins, tiglianes, and daphnanes also utilizes an oxidopyrylium cycloaddition to generate the ether constrained bicyclic (Scheme 4.81) (164). The object of the Williams study was to prepare the bicyclo[5.4.0]undecanes and investigate the regio- and stereocon-trolled oxidation of the substrate. [Pg.304]
