Antiviral and Photochemical Properties of Polyaromatic Iodinated Hemicyanines

Maxim S. Krasilnikov, V. Ya. Denisov, Stepan P. Chumakov, Yaroslav D. Orekhov et autres

ABSTRACT A series of hemicyanine derivatives was synthesized via condensation of 1,2,3,3‐tetramethyl‐3H‐indolium and its 5‐iodo and 4,6‐diiodo derivatives with polyaromatic aldehydes. Their spectral properties, singlet oxygen photogeneration, and inhibitory activity against vesicular stomatitis virus (VSV) were investigated. The aim of this study …

Structure and quenching of a bundle-shaped phycobilisome

Anna D. Burtseva, Yury B. Slonimskiy, Timur N. Baymukhametov, Maria A. Sinetova et autres

Cyanobacteria use soluble antenna megacomplexes, phycobilisomes (PBSs), to maximize light-harvesting efficiency and small photoswitchable orange carotenoid proteins (OCPs) to down-regulate PBSs in high light. Among known PBS morphologies, the one from the basal cyanobacterial genus Gloeobacter still lacks detailed structural characterization. Here, …

Enabling Fluorescence Lifetime Imaging Multiplexing Using UnaG through Its Modification with Canonical and Noncanonical Amino Acids

Valentina V. Terekhova, Daria V. Bodunova, Egor S. Gorokhov, Georgy V. Tsoraev et autres

Fluorogen-activating proteins are powerful molecular tools for microscopy, including functional imaging. These proteins serve as an alternative to GFP-like proteins, as they do not require oxygen for chromophore maturation. However, the restricted selectivity of proteins to chromophores, combined with the limited number …

Donor‐Acceptor (Perylenethienyl)Ethylenes as Singlet Oxygen‐Photogenerating Viral Inhibitors**

Roman V. Mazur, Stepan Petrovich Chumakov, V. Ya. Denisov, Yan I. Nikolaenko et autres

The development of broad-spectrum antiviral drugs effective against a wide range of viruses is of significant practical importance. Derivatives of perylene, a pentacyclic aromatic hydrocarbon, demonstrate pronounced antiviral activity. These compounds act primarily as membrane-active singlet oxygen photogenerators, disrupting virions and inhibiting …

Membrane-Active Singlet Oxygen Photogenerators as a Paradigm for Broad-Spectrum Antivirals: The Case of Halogenated (BOron)-DIPYrromethenes

Xenia A. Maryewski, Maxim S. Krasilnikov, Petra Straková, Jiří Holoubek et autres

Enveloped viruses, such as flaviviruses and coronaviruses, are pathogens of significant medical concern that cause severe infections in humans. Some photosensitizers are known to possess virucidal activity against enveloped viruses, targeting their lipid bilayer. Here we report a series of halogenated difluoroboron-dipyrromethene …

Indocarbocyanine–Indodicarbocyanine (sCy3–sCy5) Absorptive Interactions in Conjugates and DNA Duplexes

Evgeny L. Gulyak, Vladimir A. Brylev, Mikhail Y. Zhitlov, O. A. Komarova et autres

Sulfonated indocyanines 3 and 5 (sCy3, sCy5) are widely used to label biomolecules. Their high molar absorption coefficients and lack of spectral overlap with biopolymers make them ideal as linker components for rapid assessment of bioconjugate stoichiometry. We recently found that the …
