Picrotin
Picrotin is an organic heteropentacyclic compound that is picrotoxinin in which the olefinic double bond has undergone addition of water to give the corresponding tertiary alcohol. It is the less toxic component of picrotoxin, lacking GABA activity. It has a role as a plant metabolite. It is an organic heteropentacyclic compound, an epoxide, a tertiary alcohol, a gamma-lactone, a diol and a picrotoxane sesquiterpenoid. It is functionally related to a picrotoxinin. Picrotin is a natural product found in Dendrobium moniliforme and Anamirta cocculus with data available. Picrotin belongs to the class of organic compounds known as furopyrans. These are organic polycyclic compounds containing a furan ring fused to a pyran ring. Furan is a five-membered aromatic ring with four carbon atoms and one oxygen atom. Pyran a six-membered heterocyclic, non-aromatic ring, made up of five carbon atoms and one oxygen atom and containing two double bonds. Picrotin is soluble (in water) and a very weakly acidic compound (based on its pKa). C78272 - Agent Affecting Nervous System > C47795 - CNS Stimulant Picrotin is an active compound, also is one of the composition of picrotoxin (an antagonist of GABAA receptors (GABAARs) and glycine receptors (GlyRs)). Picrotin has sensitivity for GlyRs/b> with IC50 values range from 5.2 μM to 106 μM. Picrotin can be used for the research of neurotransmission[1][2].

D018377 - Neurotransmitter Agents > D018682 - GABA Agents > D018756 - GABA Antagonists Picrotoxinin is a picrotoxane sesquiterpenoid that is 3a,4,5,6,7,7a-hexahydro-1H-indene-3,7-dicarboxylic acid which is substituted at positions 3a, 6, and 7a by methyl, isopropenyl, and hydroxy groups, respectively; in which the double bond at position 2-3 has been epoxidised; and in which the carboxy groups at positions 3 and 7 have undergone gamma-lactone formation by O-alkylation to positions 4 and 5, respectively. A component of picrotoxin. It has a role as a plant metabolite, a GABA antagonist and a serotonergic antagonist. It is an organic heteropentacyclic compound, an epoxide, a tertiary alcohol, a gamma-lactone and a picrotoxane sesquiterpenoid. Picrotoxinin is a natural product found in Picrodendron baccatum and Anamirta cocculus with data available. Picrotoxinin, a potent convulsant, is a chloride channel blocker. Picrotoxinin is a noncompetitive GABAA receptor antagonist, which negatively modulates the action of GABA on GABAA receptors. Picrotoxinin inhibits α1β2γ2L GABAA receptor with an IC50 of 1.15 μM[1].
