Abstract

métodos para produzir o conjugado de maitansinóide-agente de ligação celular. a presente invenção refere-se a novos maitansinóides contendo dissulfeto que carregam uma substituição de mono ou dialquila no átomo de (alfa)-carbono que transporta o átomo de enxofre. também são apresentados métodos para a a síntese destes novos maitansinóides e métodos para a ligação destes novos maitansinóides aos agentes de ligação celular. os conjugados de maitansinóide-agente de ligação celular são úteis como agentes terapêuticos, que são liberados especificamente nas células alvos e são citotóxicos. estes conjugados apresentam eficácia terapêutica vastamente melhorada em modelos de tumor animal, comparados com os agentes anteriormente descritos.
