isoquinoline alkaloid

1. Chelidonine (Stylophorin) isolated from Chelidonium majus efficiently induced apoptosis in HeLa cells through possible alteration of p38-p53 and AKT PI3 kinase signalling pathways. 2. Chelidonine is a promising model compound for overcoming MDR and for enhancing cytotoxicity of chemotherapeutics, especially against leukaemia cells, its efficacy needs to be confirmed in animal models. 3. Chelidonine may be a potential therapeutic agent against metastasis of invasive human cancer cells, exhibits antimigratory and antiinvasive effects in MDA-MB-231 cells, by suppressing COL-induced integrin signaling, through inhibiting the formation of the IPP complex and subsequent downregulation of IPP downstream signaling molecules, such as Akt and ERK1 2.

Palmatine chloride an isoquinoline alkaloid, is an important medicinal herbal extract with diverse pharmacological and biological properties.

Jatrorrhizine (neprotin) is a protoberberine alkaloid isolated from Enantia chlorantha (Annonaceae) and other species. It was found to have antimicrobial and antifungal activity. It binds and noncompetitively inhibits monoamine oxidase (IC50 4 micromolar for MAO-A and 62 for MAO-B).

Dactyllactone A, an isoquinoline alkaloid isolated from Dactylicapnos scandens, exhibits anti-inflammatory activity. It inhibits the expression of IL-1β and PGE2.

1. Norisoboldine ((+)-Laurelliptine) might be a potential therapeutic agent for rheumatoid arthritis, and it functions through protecting joint destruction as well as regulating the abnormal immune responses. 2. Norisoboldine inhibits the macrophage activation and the resultant production of pro-inflammatory cytokines via down-regulating the activation of MAPKs signaling pathways rather than NF-κB.

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.
