    • We have now discovered that unexpectedly compounds of the following formulae I or 11 can be used to selectively stimulate the death of mammalian prostate cells, including both epithelial cell and prostate cancer cells, and thus are useful in treating prostate diseases: wherein R and R1 are each independently selected from the group consisting of hydrogen, hydroxy, thio (SH), halogen, substituted and unsubstituted alkyl, substituted and unsubstituted alkenyl, substituted and unsubstituted aryl, and substituted and unsubstituted alkoxy, and salts thereof, wherein the dotted double bond between the ring carbons to which R and R1 are bonded represent an optional ring double bond. Preferred compounds of formula I include those in which at least one of the substituents R and R1 is hydrogen and/or at least one of said substituents is allyl. Specifically preferred compounds include &bgr;-lapachone (i.e., R and R1 both being hydrogen), allyl-&bgr;-lapachone, particularly 3-allyl-&bgr;-lapachone (i.e. R being allyl and R1 being hydrogen) and 3-bromo-&bgr;-lapachone (i.e. R being bromo and R1 being hydrogen).
    • 我们现在已经发现意想不到的是,下列化学式I或11的化合物可用于选择性刺激哺乳动物前列腺细胞,包括上皮细胞和前列腺癌细胞的死亡,因此可用于治疗前列腺疾病:其中R和R1是 各自独立地选自氢,羟基,硫代(SH),卤素,取代和未取代的烷基,取代和未取代的烯基,取代和未取代的芳基,以及取代和未取代的烷氧基及其盐,其中, R和R1键合的环碳代表任选的环双键。 优选的式I化合物包括其中至少一个取代基R和R 1为氢和/或至少一个所述取代基的化合物为烯丙基。 特别优选的化合物包括β-拉帕酮(即,R和R 2都是氢),烯丙基-β-拉帕酮,特别是3-烯丙基-β-拉帕酮(即,R是烯丙基,R 1是氢)和3-溴-β-拉帕酮 (即R为溴,R 1为氢)。
