In vitro and in vivo anti-inflammatory activities of columbin through the inhibition of cycloxygenase-2 and nitric oxide but not the suppression of NF-κB translocation.
Eur. J. Pharmacol. 678(1-3) , 61-70, (2012) Columbin, a diterpenoid furanolactone, was isolated purely for the first time from the plant species Tinspora bakis. The anti-inflammatory effects of columbin were studied in vitro, in silico and in vivo. The effect of columbin on nitric oxide was examined on... |

A bitter diterpenoid furanolactone columbin from Calumbae Radix inhibits azoxymethane-induced rat colon carcinogenesis.
Cancer Lett. 183(2) , 131-9, (2002) The modifying effect of dietary administration of a diterpenoid furanolactone columbin isolated from the crude drug Calumbae Radix (the root of Jateorhiza columba MIERS, Menispermacea) on azoxymethane (AOM)-induced was investigated in male F344 rats. Animals ... |

Inhibition of Naja nigricolis venom acidic phospholipase A2 catalysed hydrolysis of ghost red blood cells by columbin.
J. Enzyme Inhib. Med. Chem. 17(1) , 55-9, (2002) The inhibitory effects of a naturally occurring diterpenoid furanolactone, columbin, on partially purified acidic phospholipase A2 (PLA2) from Naja nigricolis was investigated. Columbin inhibited the N. nigricolis PLA2 in a dose related pattern with an IC50 v... |

Columbin isolated from calumbae radix affects the sleeping time of anesthetized mice.
Biol. Pharm. Bull. 18(4) , 634-6, (1995) In a screening series of bioactive components in edible and medicinal plants, we found that Calumbae Radix (Colombo root, 1% powdered feed, for 5 d) and its component, columbin (20-40 mg/kg/d, for 5 d, orally), shortened the sleeping time induced by a urethan... |

Columbin inhibits cholesterol uptake in bloodstream forms of Trypanosoma brucei-A possible trypanocidal mechanism.
J. Enzyme Inhib. Med. Chem. 20(4) , 365-8, (2005) The diterpenoid furanolactone (columbin) from Aristolochia albida inhibited growth of culture forms of Trypanosoma brucei. In vitro analysis of the compound at 5-250 microg/ml showed complete lysis of the parasites within 10-20 minutes post incubation. At 50 ... |
