Chemical Structure
Paspalicine
- CAS No.: 11024-55-8
- Formula:C27H31NO3
- Molecular Weight:417.54
InChIKey: HSFKQYJRJBEWKH-XTHGXZEWSA-N
SMILES: C[C@@]12[C@@]3([C@](CC[C@@]1([H])CC4=C2NC5=CC=CC=C54)([H])C([C@]6(O[C@]7([H])C(C)(O6)C)CC3)=CC7=O)C
Biological Activity: Paspalicine is an indole diterpenoid fungal metabolite with no tremorgenic activity in animals. Paspalicine targets the large-conductance calcium-activated potassium (maxi-K) channel, blocks channel activity, and modulates the binding of Charybdotoxin (HY-P0191) to the maxi-K channel via a positive allosteric mechanism that enhances toxin binding. Paspalicine can be used in studies related to ryegrass staggers[1][2].
