Deltafluorine
Deltafluorine is a phosphodiesterase delta (PDEδ) inhibitor with an IC50 of 27 nM, a KD of 148 nM. Deltafluorine covalently modifies the specific glutamate residue p.E88 in the ligand binding site of PDEδ, interfering with its chaperone function. Deltafluorine inhibits signaling through the MAPK and Akt-mTOR pathway, reduces ERK1/2 expression. Deltafluorine reduces tumor volume in an autochthonous mouse model of Kras-driven lung adenocarcinoma. Deltafluorine can be used for the research of lung adenocarcinoma.
