Description

Loganin, a major iridoid glycoside obtained from Corni fructus, has been shown to have anti-inflammatory and anti-shock effects. Loganin exhibits an anti-inflammatory effect in cases of AP and its pulmonary complications through inhibition of NF-κB activation.


Loganin is an iridoid monoterpenoid with formula C17H26O10 that is isolated from several plant species and exhibits neuroprotective and anti-inflammatory properties. It has a role as a plant metabolite, a neuroprotective agent, an EC 3.4.23.46 (memapsin 2) inhibitor, an EC 3.2.1.20 (alpha-glucosidase) inhibitor, an anti-inflammatory agent and an EC 3.1.1.7 (acetylcholinesterase) inhibitor. It is a cyclopentapyran, a beta-D-glucoside, an enoate ester, a monosaccharide derivative, an iridoid monoterpenoid, a methyl ester and a secondary alcohol.

(-)-Loganin Use and Manufacturing

Methods of Manufacturing

468 mg of compound 1 and 10 mL of CH3OH, were added to 20 mL of a CH2N2/Et2O solutiongiving a yellow cloudy mixture, and the mixture was left at room temperature for 20 minuntil slow complete decolouration. The reaction mixture was bubbled with CO2 for 10 minuntil complete removal of excess diazomethane . The crude product was purified by columnchromatography on silica gel (BuOHsat) to give 428 mg of an amorphous brown powder(87.9percent yield). 1H NMR- 13C NMR and ESI-MS data and spectra are shown in S1, S2 and S3.

Uses

An iridoid glycoside that exhibits protective effects against hepatic injury and other diabetic complications associated with abnormal metabolic states and inflammation caused by oxidative stress and advanced glycation endproduct formation. A potential an
