Verruculogen

Verruculogen is a mycotoxin produced by certain strains of aspergillus that belongs to a class of naturally occurring 2,5-diketopiperazines.[2] It is an annulated analogue of cyclo(L-Trp-L-Pro) which belongs to the most abundant and structurally diverse class of tryptophan-proline 2,5-diketopiperazine natural products. It produces tremors in mice due to its neurotoxic properties. It also tested positive in a Salmonella/mammalian microsome assay and was shown to be genotoxic. It is a potent blocker of calcium-activated potassium channels.[3]

Synthesis

Both verruculogen and its isoprenyl derivative fumitremorgin A belong to the only family of alkaloids with an eight-membered endoperoxide ring, and both have been synthesised involving ligand-controlled C–H borylation.[4]

gollark: You are able to opt out of pinging using the following methods: submersion of your computing device in high-temperature molten rocks exposure of your computing device to cacti and potentially other plants ceasing all interaction with your computing device SCP-[DATA LOST] immersion of your computing device in non-high-temperature non-molten rocks, somehow submersion of your computing device in highly acidic, alkaline or based material exposure of your computing device to large amounts of kinetic energy exposure of your computing device to large amounts of psychic energy exposure of your computing device to vacuum or stellar cores
