Interestingly, although both 7h and SN38 exhibited similar inhibitory effects on Top1 activity, only 7h, and not SN38, could inhibit DDX5. These findings not only pave the way for deeper mechanistic explorations of FL118 and its derivatives in cancer research but also position the identified compound 7h as a promising candidate for further development.
Given that SN38 is the active metabolite of irinotecan, FL118 reduces cell viability and RAD51 in SN38-resistant LOVO cells. Our findings provide effective insights into the antitumor activity of FL118 and its potential as a therapeutic agent for overcoming irinotecan resistance in CRC.
Furthermore, FL118 potently induced apoptosis not only in Ba/F3 cells expressing BCR-ABL, but also in those expressing the BCR-ABL T315I mutant, which is resistant to BCR-ABL inhibitors. Collectively, these results revealed that DDX5 is a critical therapeutic target in CML and that FL118 is an effective candidate compound for the treatment of BCR-ABL inhibitor-resistant CML.
