  - MOLECULES - Year 2015

  A series of novel N-acyl-4-chloro-5-methyl-2-(R1-methylthio)benzenesulfonamides 18–47 have been synthesized by the reaction of N-[4-chloro-5-methyl-2-(R1-methylthio) benzenesulfonyl]cyanamide potassium salts with appropriate carboxylic acids. Some of them showed anticancer activity toward the human cancer cell lines MCF-7, HCT-116 and HeLa, with the growth percentages (GPs) in the range from 7% to 46%. Quantitative structure-activity relationship...

  - INORGANICA CHIMICA ACTA - Year 2019

  Benzene, toluene, ethylbenzene, and xylenes (BTEX), a class of volatile organic compounds, are harmful pollutants but also very important precursors in organic industrial chemistry. Among different approaches used for the BTEX treatment, the adsorption technology has been recognized as an efficient approach because it allows to recover and reuse both adsorbent and adsorbate. However, the selective adsorption of the components is...

  - Oncotarget - Year 2017

  nthrapyridazones, imino analogues of anthraquinone, constitute a family of compounds with remarkable anti-cancer activity. To date, over 20 derivatives were studied, of which most displayed nanomolar cytotoxicity towards broad spectrum of cancer cells, including breast, prostate and leukemic ones. BS-154, the most potent derivative, had IC50 values close to 1 nM, however, it was toxic in animal studies. Here, we characterize another...

  - Russian Journal of Physical Chemistry B - Year 2017

  Changes in the mobility of water protons in the chemically modified starches (CMS)–water system are studied by differential scanning calorimetry and NMR relaxation. The amounts of unfrozen water at negative temperatures and additional (after gelation) unfrozen for CMS are lower than those for native starch. The proton spin–spin relaxation time T2 for CMS samples, conventionally attributed to the water fraction in starch granules,...

• Multi-state multi-reference Møller-Plesset second-order perturbation theory for molecular calculations

  Publication

  • J. Franz

  - INTERNATIONAL JOURNAL OF QUANTUM CHEMISTRY - Year 2006

  This work presents multi‐state multi‐reference Møller–Plesset second‐order perturbation theory as a variant of multi‐reference perturbation theory to treat electron correlation in molecules. An effective Hamiltonian is constructed from the first‐order wave operator to treat several strongly interacting electronic states simultaneously. The wave operator is obtained by solving the generalized Bloch equation within the first‐order...

  Chiralny planarnie diantranilid został rozdzielony na enancjomery przy użyciu chlorku (-)-(1S,4R)-kamfanoilu. Konfigurację absolutną (S)-enancjomeru ustalono na podstawie analizy rentgenograficznej monokryształu jego N,N'-dikamfoilopochodnej. Natomiast rozdział ditiodiantranilidu na enancjomery przeprowadzono poprzez tworzenie związków inkluzyjnych z (R,R)-1,2-diaminocykloheksanem. Otrzymanemu w ten sposób enancjomerowi przypisano...

  Stwierdzono, że molekularna organizacja monowarstw na granicy powietrze-woda, otrzymanych z amfifilowego azofanu z nierozgałęzionym podstawnikiem n-dodecylowym różni się od tej uzyskanej dla analogu z objętościowym podstawnikiem ''tert''-oktylowym pod względem powierzchni zajmowanej przez cząsteczkę. Kompleksowanie jonów sodu z subfazy wodnej, jak wywnioskowano z pomiaru potencjału powierzchniowego, jest ułatwione w przypadku azofanu...

  - SCIENCE OF THE TOTAL ENVIRONMENT - Year 2024

  Substances that can absorb sunlight and harmful UV radiation such as organic UV filters are widely used in cosmetics and other personal care products. Since humans use a wide variety of chemicals for multiple purposes it is common for UV filters to co-occur with other substances either in human originating specimens or in the environment. There is increasing interest in understanding such co-occurrence in form of potential synergy, antagonist,...

• Selected symmetrically substituted carbazoles: Investigation of anticancer activity and mechanisms of action at the cellular and molecular levels

  Publication

  • M. Olszewski

  - Year 2024

  DNA topoisomerases play a critical role as essential enzymes in controlling alterations in the topology of DNA. They achieve this by orchestrating the coordinated process of breaking and rejoining DNA strands, which is crucial for maintaining the proper structure of DNA during regular cellular development. The search for and development of new potential anticancer drugs is a challenging yet immensely important area of research...

  Candida sp. have been responsible for an increasing number of infections, especially in patients with immunodeficiency. Species specific differentiation of the Candida sp. is difficult in routine diagnosis. This identification can have a highly significant association in therapy and prophylaxis. This work has shown a new application of terminal restriction fragment length polymorphism (t-RFLP) method in molecular identification...
