Liensinine Diperchlorate is an isoquinoline alkaloid extracted from the embryonic seeds of the sacred lotus. It inhibits late autophagy by blocking autophagosome-lysosome fusion and exhibits biological activities such as anti-arrhythmic, anti-hypertensive, anti-pulmonary fibrosis, and vascular smooth muscle relaxation.

Liensinine is the active constituent of plumula nelambinis with anti-hypertension.

Astragalin (Kaempferol 3-O-glucoside) is a biologically active natural flavonoid. It has a variety of pharmacological properties, including antioxidant, anti-inflammatory, anti-cancer, neuroprotective, and cardioprotective properties.

2-Hydroxy-1-Methoxyaporphine can inhibit CYP2D6 activity, it also increase the glucose consumption significantly as rosiglitazone.

N-Methylcoclaurine shows binding affinities for the ĸ opioid receptor with the equilibrium dissociation constant (Ki) value of 0.9 ± 0.1 uM. N-methylcoclaurine also shows promising butyrylcholinesterase inhibition activities, with the IC50 value of 1

N-Methylnuciferine is an alkaloid derived from Lotus Plumule that ameliorates lipopolysaccharide-induced depressive-like behavior.

1. Liensinine, a kind of isoquinoline alkaloid, can antagonize the ventricular arrhythmias.

O-Nornuciferine reveals distinct in vitro hERG blockages measured in HEK293 cells with the IC50 value of 2.89 uM.

Lotusine is a pure alkaloid extracted from the Nelumbo nucifera Gaertn. It shows effects on the action potentials in the myocardium and slow inward current in cardiac Purkinje fibers.

Roemerine ((-)-Roemerine) is a porphyrin alkaloid from Senegalese lychee with antifungal and anticancer activity that prevents berberine efflux through inhibition of Bmr. Roemerine increases cell membrane permeability in a concentration-dependent manner and has been used in studies of fungal infections and prostate cancer.

1. Neferine ((-)-Neferine) has anti-tumor activities , Metabolic activation mediated by CYP3A4 and GSH depletion enhanced Neferine-induced cytotoxicity. 2. Neferine can be helpful to increase the efficacy of DOX and to achieve anticancer synergism by curbing the toxicity. 3. Neferine inhibited high glucose-induced endothelial apoptosis via blocking ROS/Akt/NF-κB pathway, which provides the evidence for using Neferine to treat diabetic vasculopathy. 4. Neferine induced apoptosis in a dose-dependent manner with the hypergeneration of reactive oxygen species, activation of MAPKs, lipid peroxidation, depletion of cellular antioxidant pool, loss of mitochondrial membrane potential, and intracellular calcium accumulation.

N-norarmepavine shows significant cytotoxic activities against HL-60 carcinoma cell line with inhibitory ratios of 51.43% at concentration of 1 x 10(-5) M. Norarmepavine shows inhibition against Trypanosoma cruzi. D-(+)- N-norarmepavine exhibits significa

1. Isoliensinine (Isoliensinin), a natural phenolic bisbenzyltetrahydroisoquinoline alkaloid, has received considerable attention for its potential biological effects such as antioxidant and anti-HIV activities. 2. Isoliensinine possesses an anti-proliferative effect, which is related to the decrease of the overexpression of growth factors PDGF-beta, bFGF, proto-oncogene c-fos, c-myc and hsp7.

Nuciferine ((-)-Nuciferine) is an alkaloid found within the plants Nymphaea caerulea and Nelumbo nucifera. It has a profile of action associated with dopamine receptor blockade.

Lirinidine is an alkaloid isolated from L. tulipifera leaves with antioxidant and anticancer properties. It exhibits moderate iron-reducing capacity and small free radical scavenging capacity in vitro and can be used in cosmetic research.

Dehydronuciferine is isolated from the leaves of Nelumbo nucifera Gaertn. Dehydronuciferine shows inhibitory of acetylcholinesterase with the IC50 of 25 ug/mL.
