The invention provides a method of treating tumors by adminstering to a human or animal patient an effective amount of a molecule of 2 to 4 amino acids or equivalent subunits in length, which incorporates a bulky and lipophilic group comprising at least 13 non-hydrogen atoms and containing no more than 2 polar functional groups, in which the bulky and lipophilic group incorporates one or more closed rings of 5 or more non-hydrogen atoms, and in which the molecule further has at least two more cationic than anionic moieties.
这项发明提供了一种治疗肿瘤的方法,通过向人类或动物患者施用含有2至4个
氨基酸或等效亚单位的分子的有效量,该分子包含至少13个非氢原子的庞大和亲脂基团,并且不含有超过2个极性功能团,在这种庞大和亲脂基团中包含了一个或多个由5个或更多个非氢原子组成的闭环,并且该分子还具有至少两个阳离子基团多于阴离子基团。
