Tremorgenic indole alkaloids potently inhibit smooth muscle high-conductance calcium-activated potassium channels.[Pubmed:7514038]
Biochemistry. 1994 May 17;33(19):5819-28.
Tremorgenic indole alkaloids produce neurological disorders (e.g., staggers syndromes) in ruminants. The mode of action of these fungal mycotoxins is not understood but may be related to their known effects on neurotransmitter release. To determine whether these effects could be due to inhibition of K+ channels, the interaction of various indole diterpenes with high-conductance Ca(2+)-activated K+ (maxi-K) channels was examined. Paspalitrem A, paspalitrem C, aflatrem, penitrem A, and Paspalinine inhibit binding of [125I]charybdotoxin (ChTX) to maxi-K channels in bovine aortic smooth muscle sarcolemmal membranes. In contrast, three structurally related compounds, paxilline, verruculogen, and paspalicine, enhanced toxin binding. As predicted from the binding studies, covalent incorporation of [125I]ChTX into the 31-kDa subunit of the maxi-K channel was blocked by compounds that inhibit [125I]ChTX binding and enhanced by compounds that stimulate [125I]ChTX binding. Modulation of [125I]ChTX binding was due to allosteric mechanisms. Despite their different effects on binding of [125I]ChTX to maxi-K channels, all compounds potently inhibited maxi-K channels in electrophysiological experiments. Other types of voltage-dependent or Ca(2+)-activated K+ channels examined were not affected. Chemical modifications of paxilline indicate a defined structure-activity relationship for channel inhibition. Paspalicine, a deshydroxy analog of Paspalinine lacking tremorgenic activity, also potently blocked maxi-K channels. Taken together, these data suggest that indole diterpenes are the most potent nonpeptidyl inhibitors of maxi-K channels identified to date. Some of their pharmacological properties could be explained by inhibition of maxi-K channels, although tremorgenicity may be unrelated to channel block.
Action of tremorgenic mycotoxins on GABAA receptor.[Pubmed:2444852]
Life Sci. 1987 Nov 9;41(19):2207-14.
The effects of four tremorgenic and one nontremorgenic mycotoxins were studied on gamma-aminobutyric acid (GABAA) receptor binding and function in rat brain and on binding of a voltage-operated Cl- channel in Torpedo electric organ. None of the mycotoxins had significant effect on [3H]muscimol or [3H]flunitrazepam binding to the GABAA receptor. However, only the four tremorgenic mycotoxins inhibited GABA-induced 36Cl- influx and [35S] t-butylbicyclophosphorothionate [( 35S]TBPS) binding in rat brain membranes, while the nontremorgenic verruculotoxin had no effect. Inhibition of [35S]TBPS binding by Paspalinine was non-competitive. This suggests that tremorgenic mycotoxins inhibit GABAA receptor function by binding close to the receptor's Cl- channel. On the voltage-operated Cl- channel, only high concentrations of verruculogen and verruculotoxin caused significant inhibition of the channel's binding of [35S]TBPS. The data suggest that the tremorgenic action of these mycotoxins may be due in part to their inhibition of GABAA receptor function.
Indole diterpenoids and isocoumarin from the fungus, Aspergillus flavus, isolated from the prawn, Penaeus vannamei.[Pubmed:24983640]
Mar Drugs. 2014 Jun 30;12(7):3970-81.
Two new indole-diterpenoids (1 and 2) and a new isocoumarin (3), along with the known beta-aflatrem (4), Paspalinine (5), leporin B (6), alpha-cyclopiazonic acid (7), iso-alpha-cyclopiazonic acid (8), ditryptophenaline (9), aflatoxin B1 (10), 7-O-acetylkojic acid (11) and kojic acid (12), were isolated from the fermentation broth of the marine-derived fungus, Aspergillus flavus OUCMDZ-2205. The structures of Compounds 1-12 were elucidated by spectroscopic analyses, quantum ECD calculations and the chemical method. New Compound 1 exhibited antibacterial activity against Staphylococcus aureus with a MIC value of 20.5 muM. Both new Compounds 1 and 2 could arrest the A549 cell cycle in the S phase at a concentration of 10 muM. Compound 1 showed PKC-beta inhibition with an IC50 value of 15.6 muM. In addition, the absolute configurations of the known compounds, 4-6 and leporin A (6a), were also determined for the first time.
