title: [Mode of action at the cellular level of new thiopyrimidines with antimitotic properties].
abstract: New thiopyrimidine derivatives have been synthesized. Among them, several inhibit the multiplication of Chick embryo cells cultivated in vitro: they provoke strong nucleolar alterations, prevent the cells from entering into mitosis and can give rise to cell polyploidisation as to DNA.
