quinolizidine

1. Thermopsine (Thermospine) exhibits antibacterial activity.

Lupinine is an alkaloid capable of counteracting ethanol anesthesia. Lupinine is an AChE and BChE inhibitor and potential CD69 activator found in species of Loranthus, Calia, and Lupinus. It may also inhibit heparin.

Anagyrine hydrochloride ((-)-Anagyrine hydrochloride), a quinolizidine alkaloid discovered in Lupinus albus, interacts with both muscarinic and nicotinic acetylcholine receptors, demonstrating IC50 values of 132 and 2096 µM, respectively. This compound is recognized for its potent and direct ability to desensitize nAChR without the need for metabolic activation [1] [2] [3].

Tetrahydrorhombifoline, a quinolizidine alkaloid found in the aerial parts of Genista vuralii A. Duran & H. Dural (Fabaceae), exhibits antibacterial and antifungal activities as evidenced by the extract from G. vuralii [1].

Lupanine ((+)-Lupanine), a naturally occurring quinolizidine alkaloid, potently affinity and activates nicotinic acetylcholine receptor (nAChR) (Ki=500 nM), and shows significant neuroprotection against soluble amyloid β-oligomers (SO-Aβ) toxicity in cellular models in association with the anti-apoptotic PI3K/ Akt/Bcl-2 signaling pathway with anti-Alzheimer's disease potential. Improves glucose homeostasis by affecting KATP channels and enhancing insulin secretion with therapeutic potential for type 2 diabetes.

(-)-Sparteine ((-)-Lupinidine) is a quinolizidine alkaloid extracted from lupine, which is a voltage-gated sodium channel (VGSC) blocker with anticonvulsant activity.

MAGELLANINE is one of three natural products isolated from plant species of the Lycopodiaceae family, all sharing a distinct 6-5-5-6 fused tetracyclic bis-quinolizidine core structure.
