New ansamitocin derivatives bearing a linking group are disclosed. Also disclosed are methods for the synthesis of these new ansamitocin derivatives and methods for their linkage to cell-binding agents. The ansamitocin derivative-cell-binding agent conjugates are useful as therapeutic agents, which are delivered specifically to target cells and are cytotoxic. These conjugates display vastly improved therapeutic efficacy in animal tumor models compared to the previously described agents.

The invention provides compositions and methods for the treatment or prevention of pain. The invention provides constructs whereby hydrolysis of the construct by a specified gastrointestinal enzyme directly, or indirectly, releases an opioid when taken orally as prescribed. The gastrointestinal enzyme mediated release of opioid from constructs of the invention is designed to be attenuated in vivo via a saturation or inhibition mechanism when overdoses are ingested. The invention further provides constructs that are highly resistant to oral overdose, chemical tampering, and abuse via non-oral routes of administration.
