Leelamine HCl (16496-99-4) is a lysosomotropic, intracellular cholesterol transport inhibitor with potential chemotherapeutic activity. Induces cholesterol accumulation in lysosomal/endosomal cell compartments via inhibition of autophagic flux.1 Induces apoptosis in breast cancer2, melanoma3 and prostate cancer cells4. A selective inducer of cytochrome P450 2B.5 Inhibits pyruvate dehydrogenase kinase (PDK), IC50=9.5 µM.6
