Antibody-Drug Conjugates (ADCs): the Magic Bullets for Treatment
In recent years, Antibody-Drug Conjugates (ADCs) may serve as a novel therapeutic modality for many cancer patients. Indeed, three key elements define an ADC: the antibody directed against a specific tumor antigen, the cytotoxin/payload and the cleavable/uncleavable linker connecting the payload to the antibody [1]. Specific target recognition and effective toxin make ADCs veritable "magic bullet". These 'magic bullets' deliver treatment that is both highly targeted and highly potent, seeking out and attacking cancerous cells throughout the body, while avoiding harm to healthy cells. Reasonable selection of targets, antibody, linker, payload, and their rational combinations are crucial for an effective treatment. Among these elements, target selection, linker selection and evaluating preclinical /clinical efficacy are considered critical factors for ADCs development. >>> Download the ebook: Key point of ADCs design
