体外研究(In Vitro)

KB-0742 (6 hours; 0.1-10 μM; 22Rv1 cells) treatment significant reduction of downstream phosphorylation of RNA Pol II at Ser2 and Ser7, and diminished phosphorylation at Ser5. Global androgen receptor (AR)-FL and AR-V protein levels are significantly reduced starting at 6 h treatment time, which is accompanied by the reduction of phospho-AR levels (Ser81).
KB-0742 (48-72 hours) treatment shows cytostatic effects in prostate cancer and leukemia cell lines. KB-0742 shows antiproliferative activity with GR50s of 0.183 μM and 0.288 μM for 22Rv1 cells and MV-4-11 AML cells, respectively.
In 22Rv1 cells, KB-0742 rapidly downregulates nascent transcription, preferentially depleting short half-life transcripts and AR-driven oncogenic programs. has not independently confirmed the accuracy of these methods. The

体内研究(In Vivo)

KB-0742 (3-30 mg/kg; p.o.; daily; over 21 days) is well tolerated even at high dose, while significantly reducing tumor burden in 22Rv1 human prostate cancer cell line-derived xenograft (CDX) models. has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model:
