Resistance of human prostate carcinoma cells to a new antitumor compound capridine beta is associated with changed drug metabolism combined with both inherent and drug-induced overexpression of ABC transporters
PublicationW pracy charakteryzujemy mechanizm oporności na nową pochodną 1-nitroakrydyny, związku capridine beta (C-1748) o wysokiej aktywności przeciwnowotworowej, znajdującego się w badaniach klinicznych. Nasze dane wskazują, że oporność na ten związek jest wynikiem zmienionego metabolizmu inaktywującego C-1748 oraz wzrostem ekspresji pompy błonowej ABCG2 a także innych białek transportowych typu ABC.

Degradation of cefadroxil drug by newly designed solar light responsive alcoholic template-based lanthanum ferrite nanoparticles
PublicationIn this work, lanthanum ferrite nanoparticles were synthesized via a simple co-precipitation method. Two different templates, namely sorbitol and mannitol, were used in this synthesis to tune the optical, structural, morphological, and photocatalytic properties of lanthanum ferrite. The synthesized lanthanum ferrite-sorbitol (LFOCo-So) and lanthanum ferrite-mannitol (LFOCo-Mo) were investigated through Ultraviolet–Visible (UV–Vis),...

Technology of an adhesive silicone film as drug carrier in transdermal therapy I. Analytical methods used for characterization and design of the universal elastomer layers
PublicationSilicone polymers possess unique properties, which make them suitable for many different applications, for example in the pharmaceutical and medical industry. To create an adhesive silicone film, the appropriate silicone components have to be chosen first. From these components two layers were made: an adhesive elastomer applied on the skin, and a non-adhesive elastomer on the other side of the film. The aim of this study was...

Interactions of dissolved dsDNA with intercalating drug by anodic voltammetry and spectroscopy. Influence of pH
PublicationOddziaływanie związku przeciwnowotworowego C-1305 z DNA było badane przy pomocy impulsowej voltametrii różnicowej oraz spektroskopii UV/Vis. Triazoloakrydon C-1305 oddziałuje z DNA na dwóch drogach: przez interkalacje pomiedzy pary zasad oraz przez wiązanie sie w małym rowku helisy. W fizjologicznym pH (7,4) stałe wiązania wynoszą: K1=3,36E+5 i K2=0,18E+5 [1/M] a wielkość miejsca wiązania: n1=2,5 i n2=4,0, odpowiednio dla pierwszego...

Molecular mechanism of the enzymatic oxidation investigated for imidazoacridinone antitumor drug C-1311.
PublicationPraca miala na celu określenie molekularnego mechanizmu enzymatycznej utleniającej aktywacji wymienionego związku przeciwnowotworowego w takim układzie modelowym, w którym wcześniej wykazano jego kowalencyjne wiązanie się do DNA. Badania struktur chemicznych produktów enzymatycznej aktywacji wykazały, że dwa z nich powstają w wyniku dealkilacji łańcucha bocznego cząsteczki, natomiast dwa inne w wyniku aktywacji pierścienia imidazoakrydonu....

Regenerative Drug Discovery Using Ear Pinna Punch Wound Model in Mice
PublicationThe ear pinna is a complex tissue consisting of the dermis, cartilage, muscles, vessels, and nerves. Ear pinna healing is a model of regeneration in mammals. In some mammals, including rabbits, punch wounds in the ear pinna close spontaneously; in common-use laboratory mice, they remain for life. Agents inducing ear pinna healing are potential regenerative drugs. We tested the effects of selected bioactive agents on 2 mm ear pinna...

Controlled Random Search Applied to Parameters Estimation of the Longitudinal Solutes Transport Model for Rivers
PublicationNumerical computations are presented for the longitudinal transport of passive, conservative solutes in an actual river with the inclusion of geometrical complexities of river channels. A special emphasis is put on the method of the identification of model parameters which is based on a specially designed optimisation procedure using random control search algorithm. Two different situations are considered namely a linear version...

Establishing Relationships between Parameters of the controlled Compaction Soil by Using Various In-Situ Tests
PublicationThe aim of research was evaluating reliable correlations between chosen soil parameters describing state of surface layers of soil. The paper presents site comparative tests based on the light falling weight deflectometer (LFWD), the static plate load tester (VSS), the dynamic probing light tester (DPL) and the bearing ratio tester (CBR in-situ) with relationships between soil state parameters. All featured in-situ...

Influence of controlled crystallization and SrF2 content on the structure and properties of Eu3+ doped phosphate glasses
PublicationNew phosphate glasses and glass-ceramics P2O5–Bi2O3–K2O–Nb2O5-SrF2 doped with Eu were synthesized and studied in this work. The influence of the SrF2 content (0–15 mol%) and the parameters of the heat treatment on their structural and optical properties were investigated. For the above purpose, the structural characterization by FTIR spectroscopy and XRD measurements was carried out, which showed a significant effect of SrF2 on...

Intercalation complex of imidazoacridinone C-1311, a potential anticancer drug, with DNA helix d(CGATCG)2: stereostructural studies by 2D NMR spectroscopy.
PublicationImidazoacridinone C-1311 (Symadex®) is a powerful antitumor agent, which successfully made its way through the Phase I clinical trials and has been recommended for Phase II few a years ago. It has been shown experimentally that during the initial stage of its action C-1311 forms a relatively stable intercalation complex with DNA, yet it has shown no base-sequence specificity while binding to DNA. In this paper, the d(CGATCG)2:C-1311...

A Method for the Evaluation of Urban Freight Transport Models as a Tool for Improving the Delivery of Sustainable Urban Transport Policy
PublicationThe article presents a method which helps local authorities to evaluate urban freight transport models. Given the complex requirements for input data and the inability to supply them for most cities, a proper quantitative evaluation of model functionality may be quite difficult for local authorities. Freight transport models designed to support sustainable urban freight transport objectives are a particular example. To overcome...

Homoisocitrate dehydrogenase from Candida albicans: properties, inhibition, and targeting by an antifungal pro-drug
PublicationThe LYS12 gene from Candida albicans, coding for homoisocitrate dehydrogenase was cloned and expressed as a His-tagged protein in Escherichia coli. The purified gene product catalyzes the Mg2+- and K+-dependent oxidative decarboxylation of homoisocitrate to alpha-ketoadipate. The recombinant enzyme demonstrates strict specificity for homoisocitrate. SDS-PAGE of CaHIcDH revealed its molecular mass of 42.6±1 kDa, while in size-exclusion...
