INFOGEST inter-laboratory recommendations for assaying gastric and pancreatic lipases activities prior to in vitro digestion studies
PublikacjaIn vitro digestion studies often use animal digestive enzyme extracts as substitutes of human gastric and pancreatic secretions. Pancreatin from porcine origin is thus commonly used to provide relevant pancreatic enzymes such as proteases, amylase and lipase. Rabbit gastric extracts (RGE) have been recently introduced to provide gastric lipase in addition to pepsin. Before preparing simulated gastric and pancreatic extracts with...

In vitro biodegradation of bacterial nanocellulose under conditions simulating human plasma in the presence of selected pathogenic microorganisms
PublikacjaThe Biodegradability of bacterial nanocellulose (BNC) was assessed based on a change in its properties under conditions simulating human plasma in the presence or absence of the pathogens Staphylococcus aureus, Candida albicans and Aspergillus fumigatus. It was shown that the dry mass of BNC did not change during 6 months of incubation, except for samples stored in the presence of moulds, where the dry mass reduced by 40 %. The...

The influence of different expression of CYP3A4 izoenzymes on metabolic pathway derivatives in human hepatoma cells
PublikacjaCelem przeprowadzonych badań było określenie różnic w metabolizmie pochodnych C-857 i C-1748 w komórkach ludzkiego nowotworu wątroby HepG2 oraz określenie wpływu na ich biotransformację w podwyższonej ekspresji izoenzymu CYP3A4 w tejże linii. Uzyskane wyniki wskazały, że związek C-857, jak również C-1748 metabolizuje w komórkach HepG2 oraz Hep3A4 do wielu reaktywnych, niestabilnych metabolitów. Różnice w biotransformacji były bardzo...

Electrochemical and in silico approaches for liver metabolic oxidation of antitumor-active triazoloacridinone C -1305
Publikacja5-Dimethylaminopropylamino-8-hydroxytriazoloacridinone (C-1305) is a promising antitumor compound developed in our laboratory. A better understanding of its metabolic transformations is still needed to explain the multidirectional mechanism of pharmacological action of triazoloacridinone derivatives at all. Thus, the aim of the current work was to predict oxidative pathways of C-1305 that would reflect its phase I metabolism. The...
