Herein, we report a new conjugate BChl–S–S–NI based on the second-generation photosensitizer bacteriochlorin e6 (BChl) and a 4-styrylnaphthalimide fluorophore (NI), which is cleaved into individual functional fragments in the intracellular medium. The chromophores in the conjugate were cross-linked by click chemistry via a bis(azidoethyl)disulfide bridge which is reductively cleaved by the intracellular enzyme glutathione (GSH). A photophysical investigation of the conjugate in solution by using optical spectroscopy revealed that the energy transfer process is realized with high efficiency in the conjugated system, leading to the quenching of the emission of the fluorophore fragment. It was shown that the conjugate is cleaved by GSH in solution, which eliminates the possibility of energy transfer and restores the fluorescence of 4-styrylnaphthalimide. The photoinduced activity of the conjugate and its imaging properties were investigated on the mouse soft tissue sarcoma cell line S37. Phototoxicity studies in vitro show that the BChl–S–S–NI conjugate has insignificant dark cytotoxicity in the concentration range from 15 to 20,000 nM. At the same time, upon photoexcitation, it exhibits high photoinduced activity.
Личностные особенности и качество жизни больных, страдающих псориазом, с различной длительностью заболевания Представлены результаты обследования клинико-психопатологическим, экспериментально-психологическим, статистическим методами 39 больных, страдающих хроническим мультифакторным дерматозом-псориазом. Описаны личностные особенности в динамике заболевания, параметры качества жизни больных. Установлено, что длительность течения псориаза влияет на физическое и психологическое благополучие. Выявленные данные о личности больных позволят комплексно подходить к оценке состояние их здоровья, в случае необходимости выстраивать коррекционные мероприятия. Ключевые слова: психосоматика; псориаз; личность; качество жизни.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
