Corydalmine (L-Corydalmine) inhibits spore germination of some plant pathogenic as well as saprophytic fungi[1]. Corydalmine acts as an oral analgesic agent, exhibiting potent analgesic activity[2]. Corydalmine alleviates Vincristine-induced neuropathic pain in mice by inhibiting an NF-κB-dependent CXCL1/CXCR2 signaling pathway[3].
Corydalmine (L-Corydalmine) is a potent analgesic agent, in cynomolgus monkey, beagle dog, rat and mouse liver microsomes[2].

Levo - Corydalmine attenuates microglia activation and neuropathic pain by suppressing ASK1-p38 MAPK/NF-κB signaling pathways in rat spinal cord
Reg Anesth Pain Med 2020 Mar;45(3):219-229.PMID:31898581DOI:10.1136/rapm-2019-100875.
Background and objectives: Neuropathic pain is partially refractory to currently available treatments. Although some studies have reported that apoptosis signal-regulating kinase 1 (ASK1) may inhibit chronic pain, the mechanisms underlying this process have not been fully elucidated. Methods: Chronic constriction injury (CCI) of the rat sciatic nerve was used to establish a neuropathic pain model. Nociception was assessed using von Frey hair and Hargreaves' methods. Western blot and immunofluorescence were used to detect the cell signaling pathway. BV2 cell line was cultured for in vitro evaluation. Results: Our results indicated that spinal ASK1 was co-expressed with the microglia marker ionized calcium binding adaptor 1. Additionally, intrathecal administration of ASK1 inhibitor suppressed the activation of spinal microglia and attenuated CCI-induced neuropathic pain. The ASK1 inhibitor also decreased the levels of phosphorylated ASK1 (p-ASK1), p65, p38 mitogen-activated protein kinase (MAPK) and tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) messenger RNA in lipopolysaccharide-stimulated BV2 microglia cells. Intragastric administration of levo-corydalmine (l-CDL) significantly attenuated CCI-induced neuropathic pain and inhibited the expression of p-ASK1 in the spinal cord. l-CDL conspicuously suppressed the activation of spinal microglia in vitro and in vivo. Translocation of nuclearfactor-kappa B (NF-κB) and upregulation of p-p65, TNF-α, IL-1β were inhibited by l-CDL. Further, the analgesic effects of l-CDL were associated with reduced levels of phosphorylated protein kinase C (PKC γ), c-JunNH2-terminal kinase, and extracellular signal-regulated kinase. Conclusions: This study showed that the expression of ASK1 in spinal microglia and ASK1 inhibitor suppressed microglia activation via suppression of p38 MAPK/NF-κB, which ultimately attenuated CCI-induced neuropathic pain. l-CDL also inhibited the ASK1-P38 MAPK/NF-κB axis to attenuate CCI-induced neuropathic pain.
A new tetrahydroprotoberberine N-oxide alkaloid and anti-platelet aggregation constituents of Corydalis tashiroi
Planta Med 2001 Jul;67(5):423-7.PMID:11488455DOI:10.1055/s-2001-15820.
A new tetrahydroprotoberberine N-oxide alkaloid, (-)-cis-isocorypalmine N-oxide (1), together with two known compounds, 6-methoxydihydrosanguinarine (2) and norjuziphine (3), were isolated in continuing studies of the entire Formosan Corydalis tashiroi plant. The structures of these three compounds were determined through spectral analyses. In addition, compounds 1, 2, 3 and the seven alkaloids previously reported: (-)-cis-corydalmine N-oxide, (-)-trans-corydalmine N-oxide, (-)-trans-isocorypalmine N-oxide, scoulerine, protopine, oxysanguinarine and Corydalmine, were found to possess antiplatelet aggregation activity.
A new antibacterial denitroaristolochic acid from the tubers of Stephania succifera
J Asian Nat Prod Res 2013;15(3):315-8.PMID:23418880DOI:10.1080/10286020.2012.762641.
A new denitroaristolochic acid, demethylaristofolin C (1), together with six known alkaloids, crebanine N-oxide (2), (-)-sukhodianine-β-N-oxide (3), palmatine (4), Corydalmine (5), dehydrocorydalmine (6), and corynoxidine (7), was isolated from the tubers of Stephania succifera. The structure of demethylaristofolin C was elucidated by spectroscopic techniques (UV, IR, 1D, and 2D NMR) and HR-ESI-MS analyses. These compounds exhibited antibacterial activities against Staphylococcus aureus and methicillin-resistant S. aureus strains in different degrees.
Acetylcholinesterase inhibitors from Stephania venosa tuber
J Pharm Pharmacol 2006 May;58(5):695-700.PMID:16640839DOI:10.1211/jpp.58.5.0015.
Acetylcholinesterase (AChE) inhibitors have lately gained interest as potential drugs in the treatment of Alzheimer's disease. Three AChE inhibitors were isolated from tubers of a Thai medicinal plant, Stephania venosa (Bl) Spreng. They were identified as quaternary protoberberine alkaloids, stepharanine, cyclanoline and N-methyl stepholidine. They expressed inhibitory activity on AChE with IC50 values (concentration that caused 50% inhibition of activity) of 14.10 +/- 0.81, 9.23 +/- 3.47 and 31.30 +/- 3.67 microM, respectively. The AChE inhibitory activity of these compounds was compared with those of the related compounds, palmatine, jatrorrhizine and berberine, as well as tertiary protoberberine alkaloids isolated from the same plant, stepholidine and Corydalmine. The results suggest that the positive charge at the nitrogen of the tetrahydroisoquinoline portion, steric substitution at the nitrogen, planarity of the molecule or substitutions at C-2, -3, -9, and -10 affect the AChE inhibitory activity of protoberberine alkaloids.
Formulation and evaluation of SGLT2 inhibitory effect of a polyherbal mixture inspired from Ayurvedic system of medicine
J Tradit Complement Med 2022 Mar 22;12(5):477-487.PMID:36081821DOI:10.1016/j.jtcme.2022.03.003.
Background and aim: The ingredients viz., Artemisia roxburghiana, Cissampelos pareira, Stephania glabra, Drimia indica, Roylea cinerea, Tinospora sinensis and Curcuma longa of the present formulation are used to treat diabetes in the Indian traditional medical system. Adopting the concept of multiple herbal mixtures for better therapeutic effects from the ancient Ayurvedic text Sarangdhar Samhita, the present study aimed to develop a polyherbal formulation (PHF) of seven herbs and to evaluate its sodium-glucose cotransporter protein-2 (SGLT2) inhibitory effect on type 2 diabetic rats. Experimental procedure: Streptozotocin (STZ) (60 mg/kg) and nicotinamide (NAM) (120 mg/kg) were intraperitoneally administered to induce type 2 diabetes in Wistar rats. The animals were divided into 5 groups viz. normal control, diabetic control, positive control (dapagliflozin at 0.1 mg/kg) and two test groups (PHF at 250 and 500 mg/kg). Various parameters including blood glucose, serum glutamic pyruvic transaminase (SGPT), serum glutamic-oxaloacetic transaminase (SGOT), bilirubin, triglycerides and creatinine were measured. Results and conclusion: The treatment with PHF (250 and 500 mg/kg) showed a significant (p < 0.05) decrease in blood glucose levels by 56.37% and 58.17%, respectively. The levels of SGOT, SGPT and bilirubin were significantly reduced in PHF-fed diabetic rats. Histopathological examination revealed no major changes in the treated groups as compared to the normal control. The molecular docking study showed strong binding of β-sitosterol, insulanoline, warifteine, dehydrocorydalmine, taraxerol acetate, lupeol, Corydalmine and luteolin to SGLT2 protein. The present study concludes that PHF has promising antidiabetic activity via inhibiting SGLT2 protein without showing any adverse effects.
