Magnesium isoglycyrrhizinate (MgIG), which has been widely employed to treat
chronic hepatitis, is synthesized from 18-? glycyrrhizic acid, a main component
of traditional Chinese medicine Glycyrrhiza uralensis Fisch. Although the
protective effects of MgIG on methotrexate (MTX)-induced liver toxicity have been
well-documented, the underlying mechanism remains elusive. MTX was initially used
to treat pediatric acute leukemia, and has been widely applied to psoriasis
therapy. However, its clinical applications are limited due to hepatotoxicity and
intestinal toxicity. Herein, prophylactic administration of MgIG (9 and 18
mg/kg/day) significantly reduced the levels of aspartate aminotransferase and
alanine aminotransferase in the serum of rats receiving intravenous injection of
MTX (20 mg/kg body weight). MgIG also attenuated MTX-induced hepatic fibrosis.
Moreover, it better protected against MTX-induced hepatocyte apoptosis and
decreased the serum level of malondialdehyde than reduced glutathione (80
mg/kg/day) did. Interestingly, MTX-induced cyclooxygenase-2 (COX-2) expression,
intestinal permeability and inflammation were attenuated after MgIG
administration. In addition, MgIG (9 and 18 mg/kg) reduced MTX-induced
colocalization of zonula occludens-1 (ZO-1) and connexin 43 (Cx43) in intestinal
villi. In conclusion, MgIG exerted beneficial effects on MTX-induced
hepatotoxicity and intestinal damage, as a potentially eligible drug for
alleviating the hepatic and intestinal side effects of MTX during chemotherapy.
