Efficient syntheses of folate conjugates of tubulysins and their hydrazides 1a-d are described. These water soluble folate receptor (FR) targeted conjugates are derivatives of folic acid and the potent cytotoxic agents: tubulysin A, B, or their respective hydrazides, connected in regioselective manner via a hydrophilic peptide spacer and a reducible disulfide linker.
