Hypoxia-activated probe improves photoacoustic imaging and reduces obesity parameters in mice, indicating a new therapeutic strategy.

This research aims to develop a hypoxia-activated probe for targeted imaging and treatment of obesity-related adipose tissue.
Developed a hypoxia-activated phototheranostic probe (CBH-O) utilizing a caged Aza-BODIPY fluorophore.
Administered CBH-O nanoparticles via intraperitoneal injection in obese mice.
Conducted photoacoustic imaging and assessed photothermal conversion efficiency.
Evaluated changes in adipose tissue browning, lipolysis, and inflammation markers.
Reduced body weight by 15.6% and adipose tissue mass by 65%.
Decreased cholesterol levels in serum by 49.1% and triglycerides by 30.3%.
Lowered insulin levels by 75.7% and pro-inflammatory markers (IL-6, MCP-1).
Increased anti-inflammatory marker (IL-10).
