Ranimustine (INN, marketed under the tradename Cymerin; also known as MCNU) is a nitrosourea alkylating agent approved in Japan for the treatment of chronic myelogenous leukemia¹ and polycythemia vera.²

It has never been filed for FDA evaluation in the United States, where it is not marketed.

Synthesis

Ranimustine is made by reacting the primary amine of a pyranose sugar (2) with o-nitrophenyl N-(2-chloroethyl)-N-nitrosocarbamate (1) to form the nitrosourea group.³ ⁴
