Antioxidant and antimicrobial activity of fermented beverages obtained from fruit pomace
PublicationFruit pomace should not be considered as a waste product but as a by-product as it contains a lot of valuable components such as dietary fiber, bioactive compounds and a source of nutrients. The reasonable way to utilize these by-products, both fresh or dried, could be the fermentation of its extracts, leading to beverages with functional properties. In our research, we checked the possibility of using chokeberry, apple and...

The influence of cultivation conditions on the myrosinase activity and glucosinolate content in white cabbage
PublicationIn the process of biofumigation typically natural compounds present in Brassicaceae family are used to combat pests and protect crops. Glucosinolates, sulfur-containing secondary metabolites found in Brassica plants, are hydrolized by the enzyme myrosinase (β-thioglucosidase, EC 3.2.3.1) with the liberation of degradation products such as isothiocyanates, nitriles, thiocyanates and epithionitriles. Isothiocyanates are the most...

Combretastatin A-4 (CA-4) and its analogues. Synthesis and biological activity
PublicationSpośród wielu związków przeciwnowotworowych otrzymanych w ostatnich dwóch dekadach, na szczególną uwagę zasługują te, które powodują reorganizację mikrotubul. Jedną z takich substancji jest opisana w artykule kombretastatyna A-4 (CA-4), związek który indukuje apoptozęproliferujących komórek śródbłonka naczyń guza nowotworowego. Hamuje on polimeryzację tubuliny, prowadząc do rozpadu mikrotubul. CA-4 wyizolowana została z kory wierzby...

Investigations on the immunosuppressive activity of derivatives of mycophenolic acid in immature dendritic cell
PublicationThe main activity of mycophenolic acid (MPA) and its analogs is the inhibition of proliferation of T cells. Here, we hypothesized that MPA and its conjugates inhibits also the activity of antigen-presenting cells (APC) including dendritic cells (DCs). We tested the effect of novel amino acid derivatives of MPA and conjugates of MPA with acridines/acridones on DCs by flow cytometry, ELISA and MLR assay. Both acridines/acridone derivatives...
