PRODUCT INTRODUCTION
description
(-)-demecolcine is a secondary amino compound that is (S)-colchicine in which the N-acetyl group is replaced by an N-methyl group. Isolable from the autumn crocus, Colchicum autumnale, it is less toxic than colchicine and is used as an antineoplastic. It has a role as an antineoplastic agent and a microtubule-destabilising agent. It is an alkaloid and a secondary amino compound.
