For example, curcumin and 4-hydroxyderricin contain an acyclic α,β-unsaturated ketone that alkylates cysteines. Other antitumor or anti-inflammatory herbal compounds such as Withaferin A or zerumbone contain cyclic α,β-unsaturated ketones and react with nucleophilic residues of proteins. These observations contributed to a paradigm shift in drug design and development in the last two decades: various drugs with covalent warhead have been developed and approved. Despite the apparent importance and success of covalent warheads in current drug design and developments, the applied warheads display a rather limited structural variance and complexity which automatically limits the attainable chemical space. Furthermore, to minimize possible side-reactions during the synthesis of drugs, the applied warheads are added appendages in the late-stage of the synthetic route, thus a warhead scaffold that can be synthetically easily varied using orthogonal chemistry and used as a tunable covalent warhead is still missing. Such a structurally more complex scaffold would be much more like the warheads of the natural products and is expected to be more selective in targeting nucleophiles found on the proteins. Moreover, owing to a larger contact surface, it might be more suitable for targeting shallow protein surfaces involved in protein-protein interactions.}, year = {2024}, orcid-numbers = {Varga, Szilárd/0000-0001-9611-5168} } @{MTMT:34773104, title = {VISIBLE LIGHT SENSITIVE PHOTOREMOVABLE PROTECTING GROUPS, PREPARATION PROCESS THEREOF, PHOTOACTIVATABLE CONJUGATES COMPRISING THEM AND USES THEREOF}, url = {https://m2.mtmt.hu/api/publication/34773104}, author = {Bojtár, Márton Gáspár and EGYED, ALEXANDRA and NÉMETH, KRISZTINA and Kele, Péter}, unique-id = {34773104}, year = {2024}, orcid-numbers = {Bojtár, Márton Gáspár/0000-0001-8459-4659} } @article{MTMT:34684024, title = {Bioorthogonal Reactions in Bioimaging}, url = {https://m2.mtmt.hu/api/publication/34684024}, author = {Kozma, Eszter and Kele, Péter}, doi = {10.1007/s41061-024-00452-1}, journal-iso = {TOP CURR CHEM (2016-)}, journal = {TOPICS IN CURRENT CHEMISTRY}, volume = {382}, unique-id = {34684024}, issn = {2365-0869}, abstract = {Visualization of biomolecules in their native environment or imaging-aided understanding of more complex biomolecular processes are one of the focus areas of chemical biology research, which requires selective, often site-specific labeling of targets. This challenging task is effectively addressed by bioorthogonal chemistry tools in combination with advanced synthetic biology methods. Today, the smart combination of the elements of the bioorthogonal toolbox allows selective installation of multiple markers to selected targets, enabling multicolor or multimodal imaging of biomolecules. Furthermore, recent developments in bioorthogonally applicable probe design that meet the growing demands of superresolution microscopy enable more complex questions to be addressed. These novel, advanced probes enable highly sensitive, low-background, single- or multiphoton imaging of biological species and events in live organisms at resolutions comparable to the size of the biomolecule of interest. Herein, the latest developments in bioorthogonal fluorescent probe design and labeling schemes will be discussed in the context of in cellulo/in vivo (multicolor and/or superresolved) imaging schemes.
