Synthesis of transdermal permeation enhancers on basis of piperidine carboxylic acids derivatives I
Fratričová, Veronika ; Hrabálek, Alexandr (advisor) ; Vávrová, Kateřina (referee)
4 SYNTHESIS OF TRANSDERMAL PERMEATION ACCELERANTS ON THE BASIS OF PIPERIDIN-3-KARBOXYLIC ACID Veronika Fratričová Supervisor: Doc. PharmDr. Alexandr Hrabálek, Csc. Transdermal permation enhancers are chemical compounds which facilitate the drug delivery through the skin. They influence the stratum corneum, as the outer layer of the epidermis. Basic requirements for the enhancer are safety, drug compatibility, biodegradability, and that they must be non-toxic and non-irritating. The model structure was effective trancarbame 12, according to which have been synthetized its cyclic analogues: Hydrobromide of piperidine-3-carboxylic acid decylester Hydrobromide of piperidine-3-carboxylic acid dodecylester N-acetylderivative of piperidine-3-carboxylic acid decylester N-acetylderivative of piperidine-3-carboxylic acid dodecylester 3-(decyloxycarbonyl)piperidinium-3-(decyloxycarbonyl)piperidine-1-carbamate 3-(dodecylexycarbonyl)piperidinium-3-(dodecyloxycarbonyl)piperidine-1-carbamate Those compounds have been characterized by common spectral methods. The transdermal permation activity has been consequently evaluated on the porcine skin in the Franz cells, using theophylline as the model penetrating drug. The activity has been evaluated using the HPLC method and determined by the Microsoft Excel. The results...

Šanderová, Martina ; Dittrich, Milan (advisor) ; Šklubalová, Zdeňka (referee)
Viscosity and surface activity of the solutions of polyester carriers Student: Martina Šanderová Tutor: Assoc. Prof. Dr. Milan Dittrich, PhD. Department of Pharmaceutical Technology, Faculty of Pharmacy in Hradec Kralove, Charles University in Prague, Czech Republic This dissertation targets the viscosity research and the surface activity research of the solutions of polyester pharmaceutical carriers. In the theoretic part of this work we generaly disserted upon the viscosity, upon the surface and the intersurface tension, upon the biodegradable polymers and polyesters of aliphatic hydroxyacids. In the experimental part of this persuit we disserted on measurement and on evaluation of kinematic viscosity and the intersurface tension of different concentrated solutions of linear copolymers of the glycolic acid and D,L-lactic acid or of branched terpolymers of the glycolic acid and D,L-lactic acid. The forked adduckts were mannitol and three pentaerytritols with multiply units of quantity. Chloroform was used as solvent. For measurement of the intersurface tension was used the measuring method with using the platinum plate in accordance with Wilhelm. The results will may be used at the formulation optimalization of biodegradable preparations of the monolithic or particulate type.

The aim of this thesis is to introduce the elements and tools of public diplomacy of Spain in the Czech Republic. For this purpose, the text represents actors, which are involved in building the reputation of Spain, and government concept Marca Espana, which substantially affects a strategy presentation abroad. The thesis will focus attention not only on specific projects that Spain presents, but also monitors the use of new technologies when communicating with the Czech public. The compiled topic is founded on the study of scientific literature dealing with public diplomacy, and the subsequent application of a particular case. This thesis also examines how cooperation works between the various governmental departments in Madrid and among actors in the Czech Republic. Based on this analysis, the author concludes that the Spanish public diplomacy activities in the Czech Republic primarily have a cultural character and are presented through new media, which proves that the Spanish agenda is able to adapt flexibly to new trends in diplomacy. The main contribution of this thesis is a comprehensive presentation of all the actors of the Spanish public diplomacy and its activities, that are still deficient in wider attention in the Czech Republic.
