Cationic tensides are a widespread group of surface active agents. These compounds have lots of applications in various branches of industry and research. Quaternary isoquinolinium salts differing in alkyl chain length are members of a cationic surfactant group with quaternary nitrogen in its structure. The members of this group can be used as micellar catalysts or disinfectants. Decontamination (chemical warfare agents) or disinfection (bacteria or fungi) for very similar compounds was described several times. In this work, the preparation of isoquinoline-derived cationic surfactants differing in the length of the side alkylating chain from C8 to C20 is described. An HPLC method used for distinction of all prepared long-chain isoquinolinium analogues has been successfully developed.
Quaternary quinolinium salts differing in alkyl chain length are members of a widespread group of cationic surfactants. These compounds have numerous applications in various branches of industry and research. In this work, the preparation of quinoline-derived cationic surface active agents differing in the length of the side alkyl chains (from C₈ to C₂₀) is described. An HPLC method was successfully developed for distinction of all members of the series of prepared long-chain quinolinium derivatives. In conclusion, some possibilities of intended tests or usage have been summarized. In vitro testing using a microdilution broth method showed good activity of a substance with a C12 chain length against Gram-positive cocci and Candida species.

The paper is a presentation of the current state of development for the Atlas of Physiology and Pathophysiology (Atlas). Our main aim is to provide a novel interactive multimedia application that can be used for biomedical education where (a) simulations are combined with tutorials and (b) the presentation layer is simplified while the underlying complexity of the model is retained. The development of the Atlas required the cooperation of many professionals including teachers, system analysts, artists, and programmers. During the design of the Atlas, tools were developed that allow for component-based creation of simulation models, creation of interactive multimedia and their final coordination into a compact unit based on the given design. The Atlas is a freely available online application, which can help to explain the function of individual physiological systems and the causes and symptoms of their disorders.

An high-performance liquid chromatography (HPLC) method for identification of quaternary and non-quaternary compounds (parent compounds, intermediates, by-products, and products) within the synthesis of the acetylcholinesterase reactivator HI-6, the most promising antidote of nerve agent poisonings, is described. This HPLC method could be of high interest as a quick purity control for those who are interested in development of new acetylcholinesterase reactivators as well as for those who are interested in the synthesis of HI-6 in laboratory or in large-scale production. An HPLC method for quaternary compounds without using common ion-pairing reagents was developed, too.

Quaternary pyridinium salts with chains ranging from C8 to C20 belong in the large group of cationic surfactants. In this paper, the preparation of such cationic surface active agents based on the pyridinium moiety and differing in the length of the N-alkyl chain is described. Additionally, HPLC technique was established to distinguish each prepared pyridinium analogue. This study represents universal method for preparation and identification of quaternary pyridinium detergents.
