The invention provides carbazole compounds, and prodrugs therefor, comprising a heterogroup coupled to an aryl group, wherein the heterogroup is selected from the group consisting of SO2, S=O, C=O, NH, and PO3. The aryl group may be substituted with one or more substituents selected from the group consisting of OH, NH2, NR1R2, NHR1, OCH3, OCHR1R2, OCH2R1, OCR1R2R3, C=O, or S=O, wherein R1, R2, and R3 are alkyl groups, optionally wherein the heterogroup coupled to the aryl group is a dansyl group, and optionally wherein the heterogroup coupled to the aryl group is a fluorescent group.
The compounds are useful for the treatment of cancers, especially those with decreased Ras-association domain family 1A (RASSF1A) expression, including prostate cancer. The compounds may reduce DNA methyltransferase activity and/or increase RASSF1A expression.
Retention of the compound in a cell is diagnostic for decreased RASSF1A expression, and hence potentially for a cancer cell.
本发明提供了咔唑化合物及其原药,其包含与芳基偶联的杂基,其中杂基选自由SO2、S=O、C=O、NH和PO3组成的组。芳基可被一个或多个取代基取代,这些取代基选自由 OH、NH2、NR1R2、NHR1、OCH3、OCHR1R2、OCH2R1、OCR1R2R3、C=O 或 S=O 组成的组,其中 R1、R2 和 R3 为烷基,偶联至芳基的杂基可选为丹酰基,偶联至芳基的杂基可选为荧光基。
这些化合物可用于治疗癌症,尤其是 Ras-association domain family 1A (RASSF1A) 表达降低的癌症,包括前列腺癌。化合物可降低 DNA 甲基转移酶活性和/或增加 RASSF1A 的表达。
化合物在细胞中的滞留可诊断出 RASSF1A 表达的降低,从而可能诊断出癌细胞。
