Background:

COG 133 TFA is a fragment of Apolipoprotein E (APOE) peptide. COG 133 TFA competes with the ApoE holoprotein for binding the LDL receptor, with potent anti-inflammatory and neuroprotective effects. COG 133 TFA is also a nAChR antagonist with an IC50 of 445 nM[1][2].

COG 133 (1 mg/kg; intratracheal administration; every other day; for 4 weeks) treatment impairs the resolution of pulmonary fibrosis in mice[3].
