Consisting of three parts: targeting ligand, cleavable linker and payload, small molecule drug conjugates (SMDCs) are a promising class of targeted drugs. Giving the advantages of smaller size, better permeability, simpler preparation process and non-immunogenicity, SMDCs might be a promising alternative to antibody drug conjugates (ADCs).

小分子药物偶联物：靶向抗癌药物开发的机遇

小分子药物偶联物（SMDC）由靶向配体、可裂解连接体和有效负载三部分组成，是一类有前途的靶向药物。SMDC 具有尺寸更小、渗透性更好、制备过程更简单和非免疫原性等优点，可能成为抗体药物偶联物 (ADC) 的有前途的替代品。
