Chemical conjugates which comprise oligopeptides, having amino acid sequences that are selectively proteolytically cleaved by free prostate specific antigen (PSA) and known cytotoxic agents are disclosed. The conjugates of the invention are characterized by attachment of the cleavable oligopeptide to the oxygen atom at the 4-position on a vinca drug that has be desacetylated. Such conjugates are useful in the treatment of prostatic cancer and benign prostatic hypertrophy (BPH).
