Synthesis of transdermal permeation enhancers on basis piperidine carboxylic acids derivatives II
Kořínek, Michal ; Hrabálek, Alexandr (advisor) ; Kuneš, Jiří (referee)
Synthesis of transdermal permeation enhancers on basis of piperidine carboxylic acids derivatives II. Michal Kořínek Supervisor: Doc. PharmDr. Alexandr Hrabálek, CSc. Transdermal permeation enhancers are substances facilitating penetration of drugs through the skin. They temporarily influence stratum corneum, the outermost protective layer of epidermis. Highly effective transkarbam 12 served as a model substance. The aim of my work was to find out the effect of cyclization on its enhancing activity. The following derivatives of piperidine-4-carboxylic acid esters were synthesized: 4-(decyloxycarbonyl)piperidinium bromide 4-(dodecyloxycarbonyl)piperidinium bromide 1-acetylpiperidine-4-carboxylic acid decyl ester 1-acetylpiperidine-4-carboxylic acid dodecyl ester 4-(decyloxycarbonyl)piperidinium 4-(decyloxycarbonyl)piperidine-1-carbamate 4-(dodecyloxycarbonyl)piperidinium 4-(dodecyloxycarbonyl)piperidine-1-carbamate These unknown substances were characterized by spectral methods. The biological activity of the prepared compounds was evaluated in vitro on porcine skin in modified Franz diffusion cell with theophylline as a model permeant. The amount of theophylline was measured by HPLC method with UV detection. The results showed a significant permeation-enhancing activity of both the carbamic acid salts and...

The isolation of oligosacharides from cow' milk and their antiadhesive effects against Neisseria meningitidis
Kořínek, Michal ; Miletín, Miroslav (referee) ; Doležal, Martin (advisor)
Isolation of milk whey oligosaccharides and their anti-adhesion activity against Neisseria meningitidis Neisseria meningitidis is a human specific pathogen causing meningitis and septis. Meningococcal diseases are always very serious and can be fatal few hours after first symptoms are observed. Infants in the age of 6 to 12 months are in the highest risk to obtain meningococcal disease. Human and bovine milk oligosaccharides have been found to have inhibitory activity against several pathogens including Neisseria meningitidis. Anti-adhesive activity of acidic bovine milk whey oligosaccharides against Neisseria meningitidis was investigated in this study. Gel chromatography was used for fractination of the crude oligosaccharides isolated from bovine milk whey. The separated fractions were analyzed as regards acidic and neutral parts by measuring total hexoses and sialic acids content. The inhibitory activity of the specific acidic whey oligosaccharide fractions against the attachment of meningococcal pili was studied by using a solid-phase inhibition assay in vitro. Fractions of acidic whey oligosaccharides were found to inhibit adhesion of Neisseria meningitidis type IV pili proteins to bovine thyroglobulin that was used as a reference glycoprotein. Milk whey acidic oligosaccharides that have anti-adhesive...
