Abstract
For the first time, a liposomal form of a new original drug based on the Siberian musk deer preputial gland extract was obtained and characterized. An effective and scalable method of high-pressure homogenization was used for preparative extraction of liposomes from musk extracts. For the obtained liposomal product, such indicators as the quality of size distribution, homogeneity and the degree of inclusion of biologically active components were characterized using the methods of dynamic light scattering, transmission microscopy, preparative and analytical chromatography and chromatography-mass spectrometry. A homogeneous dispersion of musk liposomes with a uniform size distribution was obtained, with the maximum distribution values being achieved at 50 and 240 nm. The ζ-potential of the obtained nanoparticles of –35...–47 mV confirmed a high physicochemical stability of the developed liposomal dispersion. According to the gel filtration chromatography and mass spectrometry results, the degree of inclusion of the target musk extract components in the liposomes was 55–75% in terms of steroid and total protein values. The obtained quality indicators indicate that the developed liposomal composition of musk deer extracts can be used as a high-effective natural adaptogen.

ФГБУН «Научный центр биомедицинских технологий Федерального медико-биологического агентства России» 143442, Российская Федерация, Московская обл., Красногорский р-н, п. Для препаративного выделения липосом мускуса кабарги использован эффективный и масштабируемый метод гомогенизации при высоком давлении. Получены гомогенные дисперсии липосом мускуса кабарги с равномерным распределением по размерам — с максимумами распределения при 50 и 240 нм.
