Desaspidin
Desaspidin is an oxidative phosphorylation inhibitor and photophosphorylation inhibitor. Desaspidin uncouples mitochondrial oxidative phosphorylation, multiple chloroplast photophosphorylation pathways, and ATP synthesis linked to non-cyclic NADP reduction. Desaspidin can be used for the research of anthelmintic agent.

Biological Activity
Desaspidin (0.5-2.0 μM; 2 min) uncouples photophosphorylation in isolated spinach chloroplasts, with an IC50 of ~0.5 μM for XE accumulation, reducing XE half-life and ATP yield in a concentration-dependent manner[1].
Desaspidin (1.1 μM; 0.25-20 min) inhibits FMN-catalysed photophosphorylation in isolated spinach chloroplasts completely at short illumination times[1].
Desaspidin (0.1-5 μM) uncouples ferredoxin-catalysed cyclic photophosphorylation in isolated spinach chloroplasts with an IC50 of ~0.2 μM[1].
Desaspidin (100 nM-10 μM) acts as a potent, redox-dependent uncoupler of photophosphorylation in swiss chard, spinach, or lettuce chloroplasts[2].
Desaspidin (5 μM) initially uncouples FMN-driven photophosphorylation in swiss chard, spinach, or lettuce chloroplasts, but its inhibitory activity is lost over time due to photodestruction, with resistance reduced at lower chlorophyll concentrations[2].
Desaspidin (0.5 μM; 10 minutes) strongly inhibits both cyclic and noncyclic (reduced dichlorophenol indophenol-to-TPN) photophosphorylation[3].
