Verruculogen: a new substance for decreasing of GABA levels in CNS.
In our previous work we examined the mechanism of action of the new tremorogenic substance verruculogen isolated by Cole and coworkers. Examining the effect of various substances with known mechanisms of action on verruculogen-induced tremor, we concluded that this tremor was probably related to decrease of GABA levels in CNS. In order to further define the mechanisms of action of verruculogen, we determined brain GABA levels in animals in which tremor was produced by verruculogen administration. Verruculogen administration produced a decrease in GABA levels in mouse CNS. This finding substantiates our earlier suggestion that verruculogen-induced tremor is mediated by a loss of inhibitory GABA function.
