For effective delivery of triptolide (TPL) to NSCLC by pulmonary administration, a dual ligand (anti-carbonic anhydrase IX (anti-CA IX) antibody and CPP33) modified triptolide-loaded liposomes (dl-TPL-lip) was designed, synthesized, and characterized by Lin et al. [37] in 2018. The gene discussed is CA9; the disease is non-small cell lung carcinoma.
