Here we show that one of these new compounds, N-[1-(4-methoxybenzenesulfonyl)-2,3-dihydro-1H-indol-7-yl]-isonicotinamide (J30), is potently effective against various resistant and nonresistant cancer cell lines despite the status of multidrug resistance, multidrug-resistance associated protein, or other resistance factors in vitro. J30 inhibits assembly of purified tubulin by strongly binding to the colchicine-binding site. Western blot and immunofluorescence experiments demonstrate that J30 depolymerizes microtubules in the KB cell line, resulting in an accumulation of G2/M phase cells. Further studies indicate that J30 causes cell cycle arrest, as assessed by flow analyses and the appearance of MPM-2 (a specific mitotic marker), and is associated with up-regulation of cyclin B1, phosphorylation of Cdc25C, and dephosphorylation of Cdc2. J30 also causes Bcl-2 phosphorylation, cytochrome c translocation, and activation of the caspase-9 and caspase-3 cascades. These findings suggest that the J30-mediated apoptotic signaling pathway depends on caspases and mitochondria. Finally, we show that oral administration of J30 significantly inhibits tumor growth in NOD/scid mice bearing human oral, gastric, and drug-resistant xenografts. Together, our results suggest that J30 has potential as a chemotherapeutic agent for treatment of various malignancies. ------>tmu_sno=None ------>sno=22303 ------>authors2=Chang JY ------>authors3=Hsieh HP ------>authors4= ------>authors5= ------>authors6= ------>authors6_c= ------>authors=Liou JP ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c= ------>publish_area=0 ------>updateTitle=A novel oral indoline-sulfonamide agent, N-[1-(4-methoxybenzenesulfonyl)-2,3-dihydro-1H-indol-7-yl]-isonicotinamide (J30), exhibits potent activity against human cancer cells in vitro and in vivo through the disruption of microtubule. ------>language=1 ------>check_flag=None ------>submit_date=None ------>country=???? ------>no= ------>patent_SDate=2006-08-31 00:00:00 ------>update_bywho=None ------>publish_year=2009 ------>submit_flag=None ------>publish_month=1 |
