Natural products have always been an attractive source in terms of novel anti-metastatic compounds which can hinder MMP expression and activity. Corydalis heterocarpa is a salt marsh plant found in the seashores throughout Korea. Its yellow flowers and spikes have been an ingredient in folk medicine to treat spasm and contractions. The present study assessed the potential of different solvent-based fractions from the crude extract of Corydalis heterocarpa (CHE), a halophyte with reported bioactivities, to suppress the PMA-induced MMP expression in human fibrosarcoma HT-1080 cells. The solvent fractions which were named after the solvent used for fractionation (n-hexane, 85% aqueous (aq.) methanol (MeOH), n-butanol (BuOH), and H2O were shown to inhibit the both elevated mRNA and protein expression levels of MMP-2 and MMP-9 and simultaneously relieved the suppression on the expression of the endogenous MMP inhibitors TIMP-1 and TIMP-2. Results indicated that the CHE fractions might intervene with the PMA-induced activation of the MAPK signaling which is the upstream activator of MMP overexpression. Among tested samples, 85% aq. MeOH and n-hexane fractions of CHE was determined to be the most active and future studies to isolate the bioactive substances responsible for the regulation of the MMP expression are, therefore, urged. In conclusion, C. heterocarpa was shown to be a potential source of anti-metastatic compounds and n-Hexane and MeOH fractions might yield lead molecules to develop novel MMP inhibitors.
