Abstract:

Chlorophyllin (CHLN), a semisynthetic derivative of chlorophyll with antimutagenic properties, was assayed for its antiviral effect on the replication of poliovirus in cell culture. The drug was tested for the virucide, prophylactic and therapeutic activities on the replication of the poliovirus in HEp-2 cells cultures, at concentrations of 0.5 and 2.5 μg/mL. Virus titration and an indirect immunofluorescence test were used for the evaluation. The CHLN inhibited poliovirus replication in all treatment protocols; however, it was more effective on virucide treatment, with a 95.7% reduction in viral multiplication at concentration of 2.5 μg/mL. CHLN reduced the number of specifically fluorescent infected cells in both virucide and therapeutic treatments, 8h and 10h post-infection, at both concentrations (0.5 and 2.5 μg/ mL). It is suggested that CHLN either has a direct action on the virus particles or acts on the initial stage of the poliovirus replication. A clorofilina (CHLN), derivado sintético da clorofila com atividade antimutagênica, foi analisada quantoa sua atividade antiviral para o poliovírus em culturas de células HEp-2. A droga foi avaliada quanto às atividades virucida, profilática e terapêutica na multiplica o do poliovirus em culturas de células HEp-2, nas concentra es de 0,5 e 2,5 μg/mL. A inibi o do título viral e a rea o de imunofluorescência foram utilizadas para avalia o. A CHLN inibiu a multiplica o do poliovírus nos três protocolos de tratamento, porém foi mais efetiva no tratamento virucida inibindo em 95,7% a multiplica o viral na concentra o de 2,5 μg/mL. A CHLN reduziu o número de células infectadas com fluorescência específica, nos tratamentos virucida, e terapêutico, 8h e 10h pós-infec o, nas duas concentra es (0,5 e 2,5 μg/mL) . Sugere-se que a CHLN tem uma a o direta na partícula viral ou provavelmente age nos estágios iniciais da multiplica o do poliovirus.
