Nawrot, Daria Elżbieta ; Doležal, Martin (advisor) ; Musílek, Kamil (referee) ; Musiol, Robert (referee)
Univerzita Karlova, Farmaceutická fakulta v Hradci Králové Katedra Katedra farmaceutické chemie a farmaceutické analýzy Kandidát: Daria Nawrot Školitel: Prof. PharmDr. Martin Doležal, Ph.D. Název disertační práce: Studium derivátů pyridinu jako potenciálních antimykobakteriálních léčiv. Mimo období kdy tvořil COVID-19 největší hrozbu pro účinnost zdravotnických systémů na celosvětovém měřítku, zůstává tuberkuloza nejdůležitější příčinou úmrtí na infekční chorobu. Tato skutečnost, spolu se stoupající antibakteriální rezistencí, tvoří zásadní výzvu pro výzkum nových léčiv. Teoretická část tohoto komentáře krátce zvýrazňuje problematiku tuberkulozy a konkrétněji antimikrobiální rezistence. V experimentální části je vedena diskuze o návrhu, syntéze a biologickém hodnocení nových sloučenin zkoumaných během doktorského studia. Navržené sloučeniny byly připraveny a testovány na in vitro aktivitu proti vybraným mykobakteriálním kmenům (M. Avium, M. aurum, M. kansasii, M. smegmatis spolu s kmeny hlavního zájmu - Mtb H37Ra a H37Rv), osmi fungálním kmenům (Candida albicans, Candida krusei, Candida parapsilosis, Candida tropicalis, Aspergillus fumigatus, Aspergillus flavus, Absidia corymbifera, a Trichophyton interdigitale) a osmi bakteriálním kmenům (Staphylococcus aureus, Escherichia coli, Pseudomonas...
Synthesis of purine derivatives with potential antimycobacterial activity
Finger, Vladimír ; Roh, Jaroslav (advisor) ; Doležal, Martin (referee) ; Brulíková, Lucie (referee)
Charles University, Faculty of Pharmacy in Hradec Králové Department of Organic and Bioorganic Chemistry Doctoral Degree Program Bioorganic Chemistry Candidate: Ing. Vladimír Finger Supervisor: Assoc. Prof. PharmDr. Jaroslav Roh, Ph.D. Title of Doctoral Thesis: Synthesis of purine derivatives with potential antimycobacterial activity The theoretical part of this dissertation briefly summarizes basic data on tuberculosis (TB), an infectious disease caused by Mycobacterium tuberculosis (Mtb.). The epidemiological data published in the annual report of the World Health Organization (WHO) and the structure of drugs used in current TB therapy are presented. The theoretical section also gives a brief overview of the treatment of TB and mentions four compounds that are currently in phase II clinical trials. The mechanism of action of these compounds is inhibition of the enzyme decaprenylphosphoryl-β-D-ribose-2'-epimerase, specifically the DprE1 subunit. This enzyme plays an important role in the synthesis of mycobacterial call wall. The next part of the dissertation summarizes the results of research on potential purine and pyrrolo[3,2- d]pyrimidine antituberculosis agents derived from purine-6-one 10. Compound 10 was identified as derivative with moderate anti-TB activity (MIC99(Mtb) = 4 μM) in a high-...

Doležal, Martin ; Kraut, Jan (referee) ; Šulák, Pavel (advisor)
This thesis deals with the design and static assessment of a concrete part of a sewage treatment plant. Specifically, the calculation and assessment of the base plate, external walls, internal walls and ceiling slabs, elaboration of shape and reinforcement drawings of selected structural element. The concrete part of the Sewage disposal plant is all below ground level. Static system and the calculation of internal forces was carried out in Scia Engineer 2011 - student version.
Commented translation of a text on science and technology
Doležal, Martin ; Smutný, Milan (referee) ; Krhutová, Milena (advisor)
Tato bakalářská práce se zabývá používáním technického jazyka v češtině i angličtině, v čem si jsou tyto jazyky podobné a v čem se naopak liší. Pro studování jazyků v elektrotechnice byl vybrán technicky zaměřený text k přeložení a poté byl přeložen do angličtiny. Po překladu byla provedena analýza jazyka, které se zaměřovala jak na lingvistické, tak extralingvistické vlastnosti, které jsou často specifické pro odborné texty. Tyto vlastnosti pokrývají širokou škálu lingvistických oborů, jako jsou například lexikologie, morfologie, stylistika, syntax, ale i extralingvistické záležitosti, jako třeba pragmatika. Analýza originálního a přeloženého textu odhalila spoustu rozdílů, jak malých, tak i velkých, které jsou výsledkem pokusu o přenos informace v jazyce, který je poměrně rozdílný oproti originálnímu jazyku.

Study of alkali metals ions diffusion in hardened cement
Doležal, Martin ; Janča, Martin (referee) ; Šoukal, František (advisor)
This master thesis is aim to study alkali diffusion (sodium, potassium) in hardened cement paste body. It´s deal with impact of various sorroudings (hydroxide, nitrate and carbonate) in various concentrations and temperature effect. This work is also deal with changes in cement paste and medium. Teoretic part is talking about cement production and cement chemistry, alkali-silica reaction, plasticizer, diffusion an cement testing metods. This work is aimed to white (Aalborg CEM I 52,5 R – SR 5) and road (Mokrá CEM I 42,5 R – sc) cement. Experimental part describes constitution of tested cement pastes, conservation of them and sampling. Diffusion is study by ICP-AES which affected the loss of alkali from the solution and SEM which affected alkali migration (diffusion) in cement paste. In several cases, the formation of a saturated alkali edge was observed, followed by steady diffusion. In the case of potassium there was very slow diffusion through the body mass. The influence of medium and temperature was evaluated as the most significant. The effect of medium concentration wasn´t significant. Also changes in the porosity on the body were observed. The diffusion itself was affected by secondary products gorwing on the surface of body and in the medium. The work deals with them in the last part.
