OBJECTIVES: This study aimed to evaluate that the polymersomes (Ps-DOX-CA4P) dual-loaded with combretastatin-A4 phosphate (CA4P) and doxorubicin (DOX) overcame drug resistance and sensitized tumour cells to chemotherapeutic drugs. METHODS: Ps-DOX-CA4P were prepared by solvent evaporation method using mPEG-b-PLA as carriers. The potential capability of CA4P to reverse DOX resistance was verified by cytotoxicity test, apoptosis assay and cellular uptake of DOX. The comparison between free drugs and drug-loaded polymersomes was also made on a single-layer cell model and multicellular tumour spheroids to display the superiority of the drug vehicles...

OBJECTIVES: Currently, probiotics are increasingly used as the alternative to antibiotics as well as the preventive measures in humans. In particular, probiotics occupy a key position in the treatment of antibiotics-associated intestinal dysbiosis. A spore-forming microorganism lactobacillus Bacillus coagulans is one of the most promising probiotics. However, some of its pharmacological effects remain poorly understood. This study was aimed at investigation of the effect of B. coagulans (Laktovit Forte) on the intestinal dysbiosis syndrome in mice caused by streptomycin against the background of cyclophosphamide-induced cellular immunodeficiency...

OBJECTIVE: The prime objective of current work was to develop a strategy for preparation of combinational nano-formulation for reversal of drug resistance. METHODS: As a model system, doxorubicin (DOX)-resistant COLO205 cells were developed and validated. From co-treatment studies with DOX, curcumin was selected as it reversed DOX-resistance at lowest concentration. In an attempt to increase its solubility, curcumin was encapsulated into hydroxypropyl-β-cyclodextrin (HP-β-CD)...

REVIEW
Jan Schmidt, Polonca Ferk
OBJECTIVES: Much research has been performed on the field of identifying the roles of adenosine and adenosinergic signalling, but a relatively low number of marketing authorizations have been granted for adenosine receptor (AdR) ligands. In part, this could be related to their safety issues; therefore, our aim was to examine the toxicological and adverse effects data of different compounds acting on adenosinergic signalling, including different AdR ligands and compounds resembling the structure of adenosine...

OBJECTIVES: Glioblastoma (GBM) is highly proliferative, infiltrative, malignant and the most deadly form of brain tumour. The epidermal growth factor receptor (EGFR) is overexpressed, amplified and mutated in GBM and has been shown to play key and important roles in the proliferation, growth and survival of this tumour. The goal of our study was to investigate the antiproliferative, apoptotic and molecular effects of apigenin in GBM. METHODS: Proliferation and viability tests were carried out using the trypan blue exclusion, MTT and lactate dehydrogenase (LDH) assays...

OBJECTIVE: Drug-induced hepatotoxicity is a major cause of concern in patients receiving HIV/TB co-treatment. Lopinavir (LPV), an anti-HIV drug, shows poor plasma exposure due to hepatic first-pass metabolism. In this study, we investigated the effect of hepatotoxicity on pharmacokinetics of free LPV and LPV-loaded solid lipid nanoparticles (LPV SLNs) in male Wistar rats. METHODS: Hepatic impairment model in rats was developed by injecting CCl4 (i.p., 2 ml/kg). Comparative pharmacokinetic (n = 5) and tissue distribution studies (n = 3) were conducted following oral administration (20 mg/kg) of free LPV and LPV SLNs in normal and hepatic impaired rats...

OBJECTIVES: Flavonoids are a class of compounds that having the benzo-γ-pyrone skeleton, which possess anti-inflammatory properties in vitro and in vivo. The aim of this study was to investigate the inhibition of two flavonoids 7-hydroxyflavone (HF) and 7,8-dihydroxyflavone (DHF) on the production of pro-inflammatory mediators in RAW264.7 cells activated by lipopolysaccharides (LPS). METHODS: For this purpose, we selected four pro-inflammatory mediators including nitric oxide (NO), prostaglandin E2 (PGE2 ), tumour necrosis factor-α (TNF-α) and interleukin-6 (IL-6) as markers to evaluate the anti-inflammatory activity of HF and DHF...
