[Antiviral activity of 2,3-secotriterpenic hydrazones of lupane and 19beta,28-epoxy-18alpha-oleanane type].

Novel hydrazones of lupane and 19beta,28-epoxy-18alpha-oleanane type have been synthesized via interaction of 2,3-secotriterpenic aldehydonitriles with substituted hydrazines. As a result of investigation of 2,3-secotriterpenic hydrazones antiviral activity to the strain "Indiana" of vesicular stomatitis virus on two models of mammal's line cell infection, acetylhydrazone 1-cyano-2,3-seco-19beta,28-epoxy-18alpha-olean-3-al has been found to have a high prophylactic activity 0.00016 microg/ml to vesicular stomatitis virus and to inhibit a virus reproduction in primarily infected cells in 0.21 microg/ml concentration.
