Title: John Frederick Hennam: Innovator in Cancer Therapy
Introduction
John Frederick Hennam, based in Macclesfield, GB, is a notable inventor whose work has significantly contributed to the advancement of cancer treatments. With a focus on innovative chemical compounds, Hennam has obtained two patents, demonstrating his commitment to scientific research and development in the field of oncology.
Latest Patents
Hennam's latest patents involve the development of Antibody Directed Enzyme Prodrug Therapy (ADEPT) systems that leverage mutated carboxypeptidase B (CPB) enzymes for cancer treatment. These innovative enzyme conjugates are designed to be substantially non-immunogenic in humans. They include a targeting moiety, such as an antibody, which binds with tumor-associated antigens, linking it to a mutated CPB enzyme. This enzyme has the capability to convert a prodrug into an antineoplastic drug, with the critical benefit that the prodrug remains largely inactive in humans without the mutated enzyme's action. A preferred variant of the enzyme is the human pancreatic CPB, characterized by a Lys or Arg residue at position 253. The specifications also disclose suitable mustard prodrugs for this therapy, marking an important step forward in targeted cancer treatment.
