Novel Uses of small molecules, particularly, 6-methylsulfinylhexyl isothiocyanate and 6-methylsulfonylhexyl isothiocyanate, are disclosed herein. The two isothiocyanates are useful as lead compounds for manufacturing a medicament or a pharmaceutical composition for treating cancer, particularly drug-resistant cancer, in a patient.在此揭示某些小分子的新穎用途,特別是6-甲基亞磺醯己基異硫氰酸酯及6-甲基磺醯己基異硫氰酸酯化合物的新穎用途。這些異硫氰酸酯類化合物是潛在可用來製造能治療癌症,特別是具有抗藥性之癌症的醫藥品或藥學組合物的先導化合物。
