title: Inhibition of vaccinia virus replication in RK-13 cells by N,N'-bis(methylisatin-beta-thiosemicarbazone)-2-methylpiperazine.
abstract: N,N'-bis(methylisatin-beta-thiosemicarbazone)-2-methylpiperazine in a 100 mumol/l concentration inhibited the reproduction of vaccinia virus in RK-13 cells by about 90%. This compound (bis-IBTMP) had no influence on virus adsorption and on early stages of virus multiplication, but affected virus reproduction from 12 to 24 hr post-infection (p.i.). The incorporation of 3H-thymidine into infected cells increased during first 10 hr p.i., decreasing gradually afterwards. In the infected cells treated with bis-IBTMP the same tendency was observed up to 10 hr p.i., but later on the incorporation level remained unchanged. The uptake of 14C-amino acids in the presence of bis-IBTMP was reduced both in vaccinia virus-infected and non-infected RK-13 cells.
