Opis:
Flavonoids and their conjugates are the most important group of natural chemical compounds in drug discovery and development. The search for pharmacological activity and new mechanisms of activity of these chemical compounds, which may inhibit mediators of inflammation and influence the structure and function of endothelial cells, can be an interesting pharmacological strategy for the prevention and adjunctive treatments of hypertension, especially induced by pregnancy. Because cardiovascular diseases have multifactorial pathogenesis these natural chemical compounds with wide spectrum of biological activities are the most interesting source of new drugs. Extracts from one of the most popular plant used in Traditional Chinese Medicine, Scutellaria baicalensis Georgi could be a very interesting source of flavonoids because of its exact content in quercetin, apigenin, chrysin and scutellarin as well as in baicalin. These flavonoids exert vasoprotective properties and many activities such as: anti-oxidative via several pathways, anti-inflammatory, anti-ischaemic, cardioprotective and anti-hypertensive. However, there is lack of summaries of results of studies in context of potential and future application of flavonoids with determined composition and activity. Our review aims to provide a literature survey of in vitro, in vivo and ex vivo pharmacological studies of selected flavonoids (apigenin, chrysin and scutellarin, baicalin) in various models of hypertension carried out in 2008–2018.

Opis:
Introduction: Blood brain barrier and multidrug resistance phenomenon are subjects of many investigations. Mainly, because of their functions in protecting the central nervous system (CNS) by blocking the delivery of toxic substances to the brain. This special function has some disadvantages, like drug delivery to the brain in neurodegenerative diseases. Objective: The aim of this study was to examine how natural and synthetic substances affect the expression levels of genes (Mdr1a, Mdr1b, Mrp1, Mrp2, Oatp1a4, Oatp1a5 and Oatp1c1) that encode transporters in the blood-brain barrier. Methods: cDNA was synthesized from total RNA isolated from rat hippocampus. The expression level of genes was determined using real-time PCR (RT-PCR) method. Results: Our findings showed that verapamil, as a synthetic substance, caused the greatest reduction of mRNA level of genes studied. The standardized extract of Curcuma longa reduced the expression level for Mrp1 and Mrp2, whereas the increase of mRNA level was observed for Mdr1b, Oatp1a5 and Oatp1c1. Conclusions: These results suggests that herbal extracts may play an important role in overcoming the blood brain barrier during pharmacotherapy
