An antineoplastic agent especially effective against malignant brain tumors. | nimustine |
| semustine | An organochlorine compound that is urea in which the two hydrogens on one of the amino groups are replaced by nitroso and 2-chloroethyl groups and one hydrogen from the other amino group is replaced by a 4-methylcyclohexyl group. | semustine |
