Also known as 1-(2-Chloroethyl)-3-(4-methylcyclohexyl)-1-nitrosourea, 1-(2-Chloroethyl)-1-([(4-methylcyclohexyl)amino]carbonyl)-2-oxohydrazine, N-(2-Chloroethyl)-N'-(4-methylcyclohexyl)-N-nitrosourea, Methyl-CCNU

Semustine (1-(2-chloroethyl)-3-(trans-4-methylcyclohexyl)-1-nitrosourea, MeCCNU) is an alkylating nitrosourea compound used in chemotherapy treatment of various types of tumours. Due to its lipophilic property, semustine can cross the blood-brain barrier for the chemotherapy of brain tumours, where it interferes with DNA replication in the rapidly-dividing tumour cells. Semustine, just as lomustine, is administered orally. Evidence has been found that treatment with semustine can cause acute leukaemia as a delayed effect in very rare cases.

Semustine (1-(2-chloroethyl)-3-(trans-4-methylcyclohexyl)-1-nitrosourea, MeCCNU) is an alkylating nitrosourea compound used in chemotherapy treatment of various types of tumours. Due to its lipophilic property, semustine can cross the blood-brain barrier for the chemotherapy of brain tumours, where it interferes with DNA replication in the rapidly-dividing tumour cells. Semustine, just as lomustine, is administered orally. Evidence has been found that treatment with semustine can cause acute leukaemia as a delayed effect in very rare cases.

== Structure and reactivity == Semustine (Me-CCNU) is an organochlorine compound that is urea in which the two hydrogens on one of the amino groups are replaced by nitroso and 2-chloroetyl groups and one hydrogen from the other amino group is replaced by a 4-methylcyclohexcyl group. Semustine is also known as a 4-methyl derivative of lomustine.
