Abstract
The effects of double combinations of enterovirus (EV) replication inhibitors against Coxsackieviruses B1 (neurotropic Connecticut-5 strain) and B3 (cardiotropic Woodruff and neurotropic Nancy strains) were tested in cell culture experiments. Compounds with different mechanisms of action were studied: pleconaril, guanidine.HCl, MDL-860 and oxoglaucine. A three-dimensional method was applied for determining the character of the combined effect. The study determined several synergistic double combinations: guanidine.HCL + pleconaril or MDL-860 against Coxsackievirus B1; MDL-860 + each of the other EV replication inhibitors and guanidine.HCl + pleconaril against the cardiotropic Woodruff strain of Coxsackievirus B3; MDL-860 + oxoglaucine against the neurotropic Nancy strain of Coxsackievirus B3. No increased cytotoxicity was manifested in any of the tested double combinations. Keywords: antivirals; combination activity; Coxsackieviruses.
期刊介绍：
Acta virologica is an international journal of predominantly molecular and cellular virology. Acta virologica aims to publish papers reporting original results of fundamental and applied research mainly on human, animal and plant viruses at cellular and molecular level. As a matter of tradition, also rickettsiae are included. Areas of interest are virus structure and morphology, molecular biology of virus-cell interactions, molecular genetics of viruses, pathogenesis of viral diseases, viral immunology, vaccines, antiviral drugs and viral diagnostics.
