The Evaluation of DHPMs as Biotoxic Agents on Pathogen Bacterial Membranes 

Gawdzik, Barbara; Kowalczyk, Paweł; Koszelewski, Dominik; Brodzka, Anna; Masternak, Joanna; Kramkowski, Karol; Wypych, Aleksandra; Ostaszewski, Ryszard (MDPI, 2022)
Herein, we present biological studies on 3,4-dihydropyrimidin-2(1H)-ones (DHPMs) obtained via Biginelli reaction catalyzed by NH4Cl under solvent-free conditions. Until now, DHPMs have not been tested for biological activity ...

Promiscuous Lipase-Catalyzed Markovnikov Addition of H-Phosphites to Vinyl Esters for the Synthesis of Cytotoxic α-Acyloxy Phosphonate Derivatives 

Kowalczyk, Paweł; Koszelewski, Dominik; Gawdzik, Barbara; Samsonowicz-Górski, Jan; Kramkowski, Karol; Wypych, Aleksandra; Lizut, Rafał; Ostaszewski, Ryszard (MDPI, 2022-03-07)
An enzymatic route for phosphorous-carbon- bond formation is developed by discovering new promiscuous activity of lipase. This biocatalytic transformation of phosphorous-carbon- bond addition leads to biologically and ...

The Synthesis and Evaluation of Diethyl Benzylphosphonates as Potential Antimicrobial Agents 

Brodzka, Anna; Kowalczyk, Paweł; Trzepizur, Damian; Koszelewski, Dominik; Kramkowski, Karol; Szymczak, Mateusz; Wypych, Aleksandra; Lizut, Rafał; Ostaszewski, Ryszard (MDPI, 2022)
The impact of substituent at phenyl ring of diethyl benzylphosphonate derivatives on cytotoxic activity was studied. The organophosphonates were obtained based on developed palladium-catalyzed α, β-homodiarylation of vinyl ...
