title: Conjugation of triaziquinone to immunoglobulin G by a thiolation procedure catalyzed by 2-pyridinealdoxime methiodide.
abstract: Thiolation of immunoglobulin G (IgG) with DL-N-acetylhomocysteinethiolactone, catalyzed by 2-pyridinealdoxime methiodide, incorporated new sulfur groups into IgG. Triaziquinone was subsequently conjugated to the sulfur groups. Triaziquinone-IgG complex retained the alkylating activity of the drug and the immunological activity of the antibody. The conjugation procedure was inhibited by the thiol-blocking agent methyl methanethiolsulfonate.
