Кафедра "Бiотехнологiя, біофізика та аналiтична хiмiя" була створена у 1998 році на базі кафедри "Аналітична хімія", яка у 1940 році була виділена з кафедри хімії в самостійну кафедру. Ініціатива створення кафедри належить доктору технічних наук, професору Миколі Федосовичу Клещеву.

Кафедра входить до складу Навчально-наукового інституту хімічних технологій та інженерії Національного технічного університету "Харківський політехнічний інститут". Кафедра провадить освітню, методичну та наукову діяльність у галузі знань "Хімічна та біоінженерія". Крім теоретичних основ біотехнології, велику увагу було приділяється контролю якості і сертифікації біотехнологічної продукції.

У складі науково-педагогічного колективу кафедри працюють: 2 доктора наук: 1 – технічних, 1 – фармацевтичних; 8 кандидатів наук: 3 – біологічних, 5 – технічних; 2 співробітника мають звання професора, 6 – доцента.

    The study of the lipid membrane charge effect when creating liposomes with oxaliplatin
    (Національний фармацевтичний університет, 2016) Stadnichenko, O. V.; Krasnopolsky, Yu. M.; Yarnykh, T. G.
    The fight against cancer diseases is one of the most urgent problems of modern pharmacy. One of the basic standards of treatment is surgery in order to remove tumours with chemotherapeutic agents for suppression of disease manifestations. One of the ways for reducing toxicity of cytostatics is their incorporation into liposomes – nanoparticles composed of the lipid bilayer surrounding the internal cavity with the aqueous medium. Oxaliplatin is a platinum-containing chemotherapeutic agent of the 3-rd generation used as monotherapy or in combination with other drugs. When creating liposomal drugs the beginning of the work is associated with the study of the composition of the lipid membrane. The aim of the work is to study the effect of the lipid membrane charge when creating liposomes with oxaliplatin. Four types of differently charged lipid membranes for liposomal oxaliplatin formulation have been tested. Liposomes were formed by the lipid layer method with further high pressure homogenization. As a criterion the encapsulation degree was used. The highest encapsulation degree has been determined in negatively charged liposomes with the lipid membrane modified by dipalmitoyl phosphatidylglycerol (DPPG).

    Experiment planning at the pharmaceutical development of liposomal cytostatics
    (Національний фармацевтичний університет, 2017) Stadnichenko, A. V.; Krasnopolsky, Yu. M.; Yarnykh, T. G.
    At present, there is an increasing interest in developing new ways of drug delivery and targeted therapy, using nanotechnology and nanomaterials. Aim – to study the order of carrying out of pharmaceutical development of liposoms with cytostatics. Propose the scope of the experiment to optimize the planned quality indicators and technological parameters. Materials and methods. Analysis of normative documents, scientific literature and also the results of previous personal experimental studies, which became the basis for determining the methodology for the creation of liposomal drugs based on oxaliplatin and irinotecan. Lipids manufactured by Lipoid, Germany, were used to make liposomes. The lipid film was produced on a Buchi 210 rotary evaporator with a vacuum controller, at a residual pressure of 0.02 atm. For homogenization, a high pressure extrusion method was used, which was carried out on a Microfluidiser M-110P (Microfluidics, USA). Results and discussion. With the development of the pharmaceutical industry, there is a growing interest to the use of nanotechnology and nanomaterials. One of the practical implementation of nanotechnology is liposomes with cytostatics. Concentration of the active substance; pH and salt API; method of loading for API into liposomes; lipid to lipid ratio, lipids concentration; particle size and internal volume; lipid solubility in the step of lipid film preparation; stability testing of of finished products are factors that need to be studied and solved for the successful implementation of the development. Planning an experiment in the pharmaceutical development of liposomal oxaliplatin and liposomal irinotecan are complex studyes with using the principles of Quality by Design (QbD). Conclusions. The requirements of normative documentation for creating liposomal forms of medicinal products are considered. At pharmaceutical development it is necessary to use the complex approach as the majority of the put questions can not be solved separately. An experiment planning system for the pharmaceutical development of liposomal preparations of irinotecan and oxaliplatin is proposed.
