Sažetak

There are a number of compounds that can modify the activity of ATP-binding cassette (ABC) and solute carrier (SLC) transporters in the blood-brain barrier (BBB). The aim of this study was to investigate the effect of natural and synthetic substances on the expression level of genes encoding transporters present in the BBB (mdr1a, mdr1b, mrp1, mrp2, oatp1a4, oatp1a5 and oatp1c1). Our results showed that verapamil caused the greatest reduction in the mRNA level while other synthetic (piracetam, phenobarbital) and natural (codeine, cyclosporine A, quercetin) substances showed a selective inhibitory effect. Moreover, extract from roots of Panax ginseng C. A. Meyer exhibited a decrease of transcription against selected transporters whereas extract from Ginkgo biloba L. leaves resulted in an increase of the expression level of tested genes except for mrp2. Extract from aerial parts of Hypericum perforatum L. was the only one to cause an increased mRNA level for mdr1 and oatp1c1. These findings suggest that herbs can play an important role in overcoming the BBB and multidrug resistance against pharmacotherapy of brain cancer and mental disorders, based on the activity of selected drug-metabolizing enzymes and transporters located in the BBB.
