1. Dehydrocorydaline (13-Methylpalmatine) exerts anti-metastatic potential via suppression of MMPs and Bcl-2 signaling in NSC-LC cells. 2. Dehydrocorydaline stimulates p38 MAPK activation, which can enhance heterodimerization of MyoD and E proteins, thus resulting in MyoD activation and myoblast differentiation. 3. Dehydrocorydaline shows antiplatelet effects, it inhibits thrombin-induced platelet aggregation in a low dose ( IC50= 34.914 ug/mL). 4. Dehydrocorydaline has anti-inflammatory and antinociceptive effects. 5. Dehydrocorydaline inhibits MCF-7 cell proliferation by inducing apoptosis mediated by regulating Bax/Bcl-2, activating caspases as well as cleaving PARP.

L-(R,S)-Tetrahydropalmatine (Rotundine) is extracted from Corydalis yanhusuo W. T. Wang.

Tetrahydropalmatine (DL-Tetrahydropalmatine) is an active component isolated from corydalis, suppressing amygdaloid release of dopamine to inhibit an epileptic attack in rats.

N(delta)-acetylornithine is a non-protein amino acid and a defence-related plant metabolite, primarily found in Arabidopsis. The inclusion of N(delta)-acetylornithine in feed can reduce the reproduction of Myzus persicae and exhibits certain toxic properties.

Pseudocoptisine acetate is a quaternary alkaloid isolated from the tubers of Corydalis turtschaninovii,with anti-inflammatory properties.

(Rac)-11-Epicorynoline is a natural alkaloid widely used in biochemical experiments and drug synthesis research.

2,3-Dihydroxybutanoic acid is an anticancer agent extracted from the leaves of Corydalis plants. It exhibits anticancer activity both in vivo and in vitro and has a lethal effect on Ehrlich ascites tumor cells.

Bicuculline is an alkaloid extracted from Corydalis decumbens, acting as a competitive antagonist of the neurotransmitter GABAA receptor (IC50 = 2 μM). Bicuculline also blocks Ca2+-activated potassium (SK) channels and inhibits slow afterhyperpolarization (slow AHP). Bicuculline has anticonvulsant effects and is commonly used to establish mouse seizure models.

Tetrahydroberberine (Canadine) is an isoquinoline alkaloid isolated from corydalis tuber, has a micromolar affinity for dopamine D(2) receptors.

Tetrahydropalmatine hydrochloride (Gindarine hydrochloride) is an isoquinoline alkaloid found in several different plant species, mainly in the Corydalis genus (Yan Hu Suo). It is a potent muscle relaxant.

1. Dehydrocorydaline(DHC) not only inhibits antibody-mediated allergic reactions but also influences cell-mediated allergic reactions, and the inhibitory effect of Corydalis Tuber on allergic reactions may be partially attributed to DHC. 2. Dehydrocorydal

Corydine is an alkaloid discovered in Croton echinocarpus. It can inhibit reverse transcriptase (RT) activity (IC50 = 356.8 μg/mL) and has HIV inhibitory activity.

Mesocorydaline, (-)- is an alkaloid isolated from many species of Corydalis.

Allocryptopine (Thalictrimine) induces muscle contraction and relaxation in urinary bladder and ileum, respectively.

1. Tetrahydrocoptisine (STYLOPINE) has effective effects in suppressing inflammation. 2. Tetrahydrocoptisine possesses a protective effect on LPS-induced ALI through inhibiting of NF-κB signaling pathways, which may involve the inhibition of pulmonary inflammatory process. 3. Tetrahydrocoptisine has gastroprotective activity, is attributed to reducing NO production and adjusting the pro-inflammatory cytokine, inhibited neutrophil accumulation and NF-κB expression. 4. Tetrahydrocoptisine is an active anti-inflammatory constituent by inhibition of TNF-α, IL-6 and NO production possibly via down-regulation of NF-κB activation, phospho-ERK1/2 and phospho-p38MAPK signal pathways.

Glaucine has antitussive, antioxidative potential and antiviral activities, it may be an anti-arthritic agent, it can enhance LPS and zymosan-induced IL-10 production. Glaucine can inhibit the migration and invasion of human breast cancer cells by MMP-9 i

1. Acetylcorynoline (O-Acetylcorynoline) has antifungal,anti-inflammatory activity. 2. Acetylcorynoline may be one of the potent immunosuppressive agents through the blockage of dendritic cells maturation and function. 3. Acetylcorynoline is potential as a possible antiparkinsonian drug. (1) Significantly decreases dopaminergic neuron degeneration induced by 6-hydroxydopamine in BZ555 strain; (2) Prevents α-synuclein aggregation; (3) Restores food-sensing behavior, and dopamine levels; (4) Prolongs life-span in 6-hydroxydopamine-treated N2 strain. 4. Acetylcorynoline may exert its effects by decreasing egl-1 expression to suppress apoptosis pathways and by increasing rpn5 expression to enhance the activity of proteasomes.

1. Corydaline (Corydalin), an isoquinoline alkaloid, is one of the major active constituents in a new prokinetic botanical agent. 2. Corydaline promotes gastric emptying and small intestinal transit and facilitates gastric accommodation. 3. Corydaline exhibits the anti-acetylcholinesterase, antiallergic, and antinociceptive activities. 4. Corydaline has potent inhibition of CYP2C19 and CYP2C9.

1. Epiberberine may be caused drug interactions based on CYP2D6 enzyme. 2. Epiberberine has anti-adipogenic effect is mediated by downregulation of the Raf/MEK1/ERK1/2 and AMPKα/Akt pathways during 3T3-L1 adipocyte differentiation. 3. Epiberberine, as the brightest FSA emitter among the alkaloids, can also serve as an efficient conformation probe for HTG DNA and discriminate the DNA G-quadruplex from the RNA counterpart.
