Shuttle Pharmaceuticals Holdings, Inc, a Maryland-based developer of new drugs for cancer treatment, was awarded US Patent No.: 11,034,667 B2 for "Selective Histone Deacetylase Inhibitors for the treatment of Human Disease."

These non-cytotoxic, highly selective inhibitors target the histone deacetylase 6 (HDAC6) enzyme to stimulate the immune system for applications in the treatment of cancers, neurological diseases and immunological disorders.

Lead inventor Scott Grindrod, PhD describes histone deacetylase (HDAC) inhibitors as "a novel class of drugs that target enzymes involved in the regulation of critical cellular functions that can inhibit cancer growth and activate cellular immunity. These are key target functions to improve cancer treatment.

HDAC6 regulates the innate immune system and will be tested to activate an anti-cancer immune response to increase the effectiveness of chemotherapy and radiation therapy. The molecules in this patent enhance Shuttle Pharma's platform technology of selective inhibitor discovery for cancer treatment."
