Pseudocoptisine chloride 是从 Corydalis Tuber 中分离出来的，具有抗炎和抗健忘的作用。 Pseudocoptisine chloride 抑制乙酰胆碱酯酶 (AChE) 活性 (IC50 = 12.8 μM)。

Pseudocoptisine chloride is isolated from Corydalis Tuber with anti-inflammatory and anti-amnestic properties. Pseudocoptisine chloride inhibits acetylcholinesterase (AChE) activity (IC50 = 12.8 μM).

In RAW264.7 cells, Pseudocoptisine chloride (0, 60, 90 μM; 1 hour) inhibited LPS-induced NO production in a dose-dependent manner[1]. Pseudocoptisine chloride reduced levels of the pro-inflammatory mediators, such as, iNOS, COX-2, TNF-alpha, and IL-6 through the inhibition of NF-kappaB activation via the suppression of ERK and p38 phosphorylation. Pseudocoptisine chloride (30-90 μM; 1 hour) significantly reduced the LPS-induced TNF-α and IL-6 production and their mRNA expressions[2].

Pseudocoptisine chloride (2.0 mg/kg, p.o.) showed anti-amnesic activities on the learning and memory impairments induced by scopolamine (1.0 mg/kg, i.p.) and significantly reverses cognitive impairments in mice by passive avoidance test[2].
