Delsoline
Delsoline has hypotensive effects.Delsoline is not only effective in preventing ventricular fibrillation and arrythmia, but can raise the intebsity of the threthold of electrical shocks to cause ventricular fibrillation in rabbits, the antiarrythmic effect of it may be mainly attributed to itsganglionic blocking and negative cardiac inotropic effect.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Antiarrythmic effect of delsoline[Reference:
WebLink]
Delsoline ( DS ) is not only effective in preventing ventricular fibrillation ( induced by chloroform in mice ) and arrythmia ( induced by adrenalin in rabbits), but can raise the intebsity of the threthold of electrical shocks to cause ventricular fibrillation in rabbits.Furthermore , DS can obviously inhibit the action potential amplitude of isolated sciatic nerves in toads, indicating that it can block sodium channels. However, the antiarrythmic effect of DS may be mainly attributed to itsganglionic blocking and negative cardiac inotropic effect.

Nudicauline and elatine as potent norditerpenoid ligands at rat neuronal alpha-bungarotoxin binding sites: importance of the 2-(methylsuccinimido)benzoyl moiety for neuronal nicotinic acetylcholine receptor binding.[Pubmed:
8941400]
Methyllycaconitine (MLA, 1) is a novel, potent probe for mammalian and insect nicotinic acetylcholine receptors (nAChR) and displays remarkable selectivity toward neuronal [125I]-alpha-bungarotoxin (alpha BgTX) binding sites that correspond to alpha 7-type nAChR in mammalian brain.
METHODS AND RESULTS:
We have shown that, among a number of selected norditerpenoid alkaloids, elatine (2) and nudicauline (3) are equipotent with, or better than, MLA (1) in binding to brain [125I]-alpha BgTX binding sites, with IC50 values of 6.1, 1.7, and 7.6 nM, respectively. The 2-((S)-methylsuccinimido)benzoyl moiety of these ligands is crucial for high-affinity binding, whereas structural modifications to the norditerpenoid core of the ligand can be tolerated without loss of activity or selectivity. In addition to MLA (1), elatine (2), and nudicauline (3), we have examined lycoctonine (4), inuline (6), lappaconitine (7), N-desacetyllappaconitine (8), Delsoline (10), delcorine (11), deltaline (12), condelphine (13), and karacoline (14).
CONCLUSIONS:
This study therefore extends the range of norditerpenoids, other than MLA, which can be used to probe this important class of nAChR. All 12 alkaloids were assessed for activity at [3H]nicotine binding sites which are considered to represent alpha 4 beta 2 nAChR. Furthermore, the 1H and 13C NMR spectroscopic data of MLA and elatine have been critically compared.
