SIAIS178

SKU: orb1708526

Description

SIAIS178 is a potent and selective PROTAC molecule that targets BCR-ABL for degradation via recruitment of the VHL E3 ligase, with an IC50 of 24 nM. It demonstrates robust anti-proliferative activity in leukemia cell cultures and has been shown to induce regression in K562 xenograft tumor models in vivo.

Bioactivity

• Target IC50:
  VHL:24 nM|BCR-ABL:24 nM
• In Vivo:
  Methods: SIAIS178 (5, 15, and 45 mg/kg) was used to treat K562-Luc NOD/SCID mice and investigate its effect on tumor progression in vivo. Results: SIAIS178 attenuated tumor progression in a dose-dependent manner as determined by serial volume measurements.
• In Vitro:
  Methods: K562 cells were treated with SIAIS178 (1, 3, 10, 30, 100 nM, 16 hours) and BCR-ABL protein expression was detected by Western blot. Results: SIAIS178 significantly reduced BCR-ABL protein levels in a concentration-dependent manner.
