Myrophine

Myrophine (Myristylbenzylmorphine) is an opiate analogue that is a derivative of morphine.

Myrophine is substituted with a 3-benzyl group and a 6-myristyl chain. It is metabolised to form benzylmorphine and then further to morphine, and so is a long-acting prodrug for morphine, but with a slow onset of effects. It is a Schedule I drug in the USA and is controlled under international drug conventions.
