DM1 can also be linked via a more complicated structure – 4-(3-mercapto-2,5-dioxo-1-pyrrolidinylmethyl)-cylohexanecarboxylic acid or SMCC –, in which case the International Nonproprietary Name of the conjugate formed contains the word emtansine. The abbreviation comes from the chemical designation "succinimidyl-"trans"-4-(maleimidylmethyl) cyclohexane-1-carboxylate" which is used in the primary literature as well as by the World Health Organization (WHO) despite the fact that the linker contains only one imide group according to the WHO.
