| abstract |
An Estracyt compound having a carcinostatic bound thereto is obtained by reacting an Estracyt compound with a carcinostatic having one or more radicals selected from among COOH, Cl, NH 2 and OH, either directly or after reaction with an amine to replace one or both Cl groups in the nitrogen mustard portion in the Estracyt compound with a NH 2 group, in the presence or absence of a catalyst. The resulting compound is more effective in cancer control than the Estracyt compound associated substance. |
