    1,9-Dimethylmethylene blue

    		Fluorescent Dye VSV Infection
    1,9-Dimethylmethylene blue is a photosensitizer, virus inactivator and hemoglobin oxidant derived from methylene blue. When activated, 1,9-Dimethylmethylene blue generates reactive oxygen species including singlet oxygen, and acts as a metachromatic dye. When activated in monomeric or dimeric form, 1,9-Dimethylmethylene blue induces photoinactivation of R17 phage and vesicular stomatitis virus and oxidizes hemoglobin via non-singlet oxygen reactive oxygen species or singlet oxygen-mediated pathways, respectively. The monomeric form, with higher nucleic acid affinity, achieves virus inactivation under specific conditions without forming methemoglobin. 1,9-Dimethylmethylene blue binds to substances such as glycosaminoglycans to produce color changes. Although it is susceptible to interference from non-glycosaminoglycan components in urine, it is still applicable to spectrophotometric analysis for glycosaminoglycan quantification. With these unique photochemical and binding properties, 1,9-Dimethylmethylene blue is widely used in studies of viral infections and related biochemical analyses .

    TLD-1433

    		Reactive Oxygen Species (ROS) Influenza Virus SARS-CoV HSV Infection
    TLD-1433 is the fourth-generation ruthenium (II) based photodynamic compound (PDC). TLD-1433 is activated by green light (525 ± 25 nm) and efficiently generates ROS to achieve pathogen inactivation. After photoinactivation, TLD-1433 significantly induces lipid peroxidation of the cell membrane, which can directly damage the integrity of the viral envelope. TLD-1433 has ID50 for enveloped viruses (such as H1N1 influenza virus, coronavirus OC43, HSV-1, Zika virus) is as low as nanomolar level; for non-enveloped viruses (such as adenovirus Ad5, mammalian rotavirus MRV), a concentration of micro-molar level is required for inactivation. TLD-1433 has antigen retention property and can be used for the preparation of inactivated vaccines .
