PROTAC-O4I2

SKU: orb1983144

Description

PROTAC-O4I2 is a heterobifunctional degrader that targets the splicing factor SF3B1, inducing its degradation with an IC50 of 0.244 µM in K562 cells and triggering apoptosis. This molecule serves as a valuable chemical probe for studying RNA splicing mechanisms and cancer cell survival in leukemia research models.

Bioactivity

• In Vivo:
  Flies were fed on a round filter paper loaded with PROTAC-O4I2 (10 μM) in a 5% sucrose solution, maintained at 18℃, and flipped into a freshly prepared vial every 2 days. PROTAC-O4I2 significantly improves Drosophila survival in a Drosophila intestinal tumor model by interfering with tumor maintenance and proliferation.

• In Vitro:
  PROTAC-O4I2 introduces thalidomide into the ubiquitin E3 ligase cereblon (CRBN), thereby selectively degrading SF3B1 and inhibiting tumor growth in cells. PROTAC-O4I2 degrades and inhibits SF3B1 in K562 cells. PROTAC-O4I2 has anti-proliferative effects on SF3B1 WT, SF3B1 OE, and SF3B1 K700E cells with IC50 of 228, 63, and 90 nM, respectively. PROTAC-O4I2 induces FLAG-SF3B1 degradation in a concentration-dependent manner, with a half-maximal inhibitory concentration (IC50) value of 0.244 μM in K562 cells.
