文献和实验Proteasome Inhibitors in Cancer Therapy
bortezomib (VELCADE�, formerly known as PS-341), has recently been approved in the United States for treatment of patients with multiple myeloma who have received at least two prior therapies, and have demonstrated disease progression on their last therapy
Small-Molecule Inhibitors of Proteasome Activity
The fast-track approval of a proteasome inhibitor, PS-341, to treat multiple myeloma spurred a wave of interest in both the proteasome itself and small-molecule compounds blocking its activities. Besides being candidates for drugs
IkB-a突变体阻断NF-kB活化:优点,靶点明确;缺点,抑制效率不如RNAi 4、抑制剂(PDTC、SN50等):优点,应用方法简单;缺点,特异性不强,且作用靶点各异(见下面键接),还可能存在细胞特异性。在此需要指出的是,一些传统药物如糖皮质激素、水杨酸类、砷剂和全反式维甲酸等以及姜黄素、大豆异黄酮等天然化合物经证实也是NF-kB抑制剂;蛋白酶抑制剂PSI、PS-341等可阻止IkB-a磷酸化等,从而也可实现抑制NF-kB活化。 各抑制剂的机制可参见下帖: http
