N-acylpeptides with glucosamine-6-phosphate synthase inhibitors - synthesisand antifungal activity
PublikacjaOpracowano syntezę kilku peptydów (di i tripeptydów) zawierających inhibitory syntazy glukozamino-6-fosforanu oraz przeprowadzono je w N-acylopochodne (acetylowe, heksanoilowe, dekanoilowe) oraz zbadano ich aktywność przeciwgrzybową w stosunku do szczepów Candida albicans z opornością wielolekową. Stwierdzono, że N-acylopeptydy wykazują aktywność przeciwgrzybową oraz określono wartości MIC.

Facilitated diffusion of glucosamine-6-phosphate synthase inhibitors enhances their antifungal activity
PublikacjaKwas N-3(4-metoksyfumaroilo)-L-2,3-diaminopropanowy (FMDP) i 2-amino-2-deo-ksy-D-glucitolo-6-fosforan (ADGP) są silnymi inhibitorami syntazy glukoza-mino-6-fosforanu, istotnego enzymu grzybowego, jednak ich aktywność przeciwgrzybowa jest słaba, ze względu na powolną penetrację tych związków przez błonę cytoplazmatyczną. W tej pracy badaliśmy możliwość poprawy działania przeciwgrzybowego ADGP i FMDP poprzez zwiększenie ich własności...

Targeting Spike‐ACE2 Interface of SARS‐CoV‐2 and its Omicron Variant: A Comparative Screening of Potential Inhibitors for Existing and Anticipating Variants Using Molecular Modelling Approach
PublikacjaThe recent COVID pandemic has shown major impact on public health and economic crisis. Despite the development of many vaccines and drugs against the severe acute respiratory syndrome (SARS) coronavirus 2, the pandemic still persists. The continued spread of the virus is largely driven by the emergence of viral variants such as α, β, γ, delta, epsilon spike, omicron and its subvariants (BA.1,2,3) which can evade the current vaccines...

Chloroacridine derivatives as potential anticancer agents which may act as tricarboxylic acid cycle enzyme inhibitors
PublikacjaThe chloroacridines affect biological forms of melanoma in different ways. Amelanotic (Ab) melanoma (with inhibited melanogenesis and higher malignancy) was particularly sensitive to the action of the chloroacridines. The Ab melanoma cells died through apoptosis and through death without caspase activation. Diminished activity of TAC enzymes was noticed among Ab melanoma cells together with ATP/NAD depletion, especially in the...
