(-)-Isocorypalmine是一种从 Corydalis yanhusuo W. T. Wang（延胡索）块茎中提取的天然生物碱。它是多巴胺受体（D1 激动剂和 D2 拮抗剂）的配体，显示出抗真菌活性，并在治疗可卡因成瘾的研究中具有潜在价值。重组 CYP719A21 对其的底物特异性高 (Km=4.63 μM)。

(±)-Stylopine是一种从延胡索块茎中分离和提纯的天然生物碱化合物，具有抗炎和抗寄生虫活性。

Corydaline是从延胡索中提取的异喹啉生物碱，是一种 AChE 抑制剂（IC50 = 226 μM）和 μ 阿片受体激动剂（Ki = 1.23 μM），具有抗过敏、抗血管生成和胃动力增强作用，用于神经疾病和病毒感染研究。

Scoulerine是一种抗有丝分裂化合物，也抑制BACE1，能阻止细胞周期并诱导癌细胞凋亡。

Dehydrocorydaline (13-Methylpalmatine)是一种生物碱，能调节Bax和Bcl-2蛋白的表达，激活caspase-7和caspase-8，并使PARP失活。它能增强p38 MAPK的活性，具有抗炎和抗癌活性，表现出强效的抗疟疾作用（IC50 = 38 nM），且在使用疟原虫3D7菌株时细胞存活率超过90%，表明其细胞毒性较低。

Acetylcorynoline是一种从延胡索（Corydalis ambigua）块茎中分离和纯化的天然产物，具有抗真菌和抗炎活性。

13-Methylberberine chloride是黄连素的类似物，具有抗脂肪和抗肿瘤活性。其能够增加 IL-12 的产生，并在 LPS 激活的巨噬细胞中转录后抑制 iNOS 的表达，适用于肿瘤免疫及代谢紊乱相关研究。

Tetrahydropalmatine inhibits the LPSinduced production of COX-2 protein and mRNA in a dose-dependent manner.

Dihydroberberine是从 Corydalis decumbens（垂花忍冬）块茎中提取的天然产物，具有抗肿瘤活性。Dihydroberberine 可以改善高脂饮食小鼠的体内疗效，抵消脂肪堆积、组织甘油三酯积累和胰岛素抵抗，因此是潜在的 2 型糖尿病治疗药物。

Corypalmine, a natural product isolated and purified from the bulbs of Corydalis yanhusuo, inhibits prolyl oligopeptidase with IC50 of 128.0±10.5 uM, and shows inhibition activity against spore germination of some fungi.

(-)-Corydalmine exhibits antibacterial activities against staphylococcus aureus and methicillin-resistant S.

Corydine is found in tubers of corydalis tuberosa DC. with antimicrobial and antineoplastic activities. It can act as an adrenolytic and weak cholinergic agent.

Epiberberine chloride, a natural alkaloid, is a BACE1 inhibitor, which also exhibits inhibition activity on CYP2D6 and aldose reductase, alpha-adrenoceptors, acetylcholinesterase (AChE), butyrylcholinesterase, and b-site amyloid precursor protein cleaving enzyme 1.

Canadine, a natural product isolated and purified from the bulbs of Corydalis yanhusuo, has antioxidant activity with low-toxic effect.
