专利号:WO-2024002966-A1 优先权日:2022-06-29 标题 :Hydrophilic phenalenones and their use in antimicrobial photodynamic therapy 发明人:COEFFARD VINCENT; DE BONFILS PAUL; NUN PIERRICK; ZITOUNI BÉCHIR; SOL VINCENT; VERNISSE CHARLOTTE; OUK TAN-SOTHEA; GUNTHER GERMAN 权利人:CENTRE NAT RECH SCIENT; UNIV NANTES; UNIV OF CHILE; UNIV LIMOGES 摘要:The present invention belongs to the field of antimicrobial compositions and antimicrobial photodynamic therapy, and more specifically to hydrophilic phenalenones and their use in said field. It relates more specifically to new yellow-fluorescent phenalenone photosensitizers for applications in antimicrobial photodynamic therapy (aPDT). The present invention relates to new hydrophilic phenalenones compounds and their use as a medicine, in antimicrobial photodynamic therapy, and more specifically in the treatment of various diseases, such as acne vulgaris, periodontis infections, rosacea, ptyriasis versicolor, molluscum contagiosum, genital herpes, tinea pedis, endodontics infections, viral keratitis, COVID-19 or influenza. The invention also relates to the method of synthesis of new hydrophilic phenalenone compounds according to the invention.
专利号:US-10138510-B2 优先权日:2008-05-16 标题 :Dual labeling methods for measuring cellular proliferation 发明人:CLARKE SCOTT; BRADFORD JOLENE 权利人:LIFE TECHNOLOGIES CORP 摘要:The present invention provides a method for measuring cellular nascent nucleic acid synthesis by dual pulse labeling of nucleic acid. The first pulse labeling of nucleic acid with a nucleoside analog allows establishment of a baseline nucleic acid synthesis rate. Pulse labeling of the nucleic acid with a second nucleoside analog then allows measurement of any changes to nucleic acid synthesis. The nucleic acid synthesis can be measured as cell proliferation, DNA, or gene expression, RNA. This method does not require a potentially artifact-inducing intermediary wash step between pulse labels. Additionally, this method may be used to screen compounds for their affect on cellular proliferation by treating cells or an organism with the test compound simultaneous to or before treatment with a competitive nucleoside analog.

专利号:US-9341631-B2 优先权日:2007-06-05 标题 :Long wavelength fluorogenic intracellular ion indicators that are well retained in the cytosol 发明人:GEE KYLE; MARTIN VLADIMIR 权利人:GEE KYLE; MARTIN VLADIMIR; LIFE TECHNOLOGIES CORP 摘要:Cell permeable metal ion indicator compounds and methods of their use and synthesis are described. The compound comprises a metal chelating moiety (M c ), a reporter molecule and two or more lipophilic groups (G L ) covalently bonded through a linker to the reporter molecule, wherein the lipophilic groups, when present in a live cell, are cleaved resulting in two or more negatively charged groups. An exemplary compound for use as a cell permeable metal ion indicator is represented by the structure:
