Figure 9. Influence of PEG-Peptide Size on Scavenger Receptor Inhibition.
The percent of 125I-PEG-peptide recovered from the liver at a biodistribution time of 5 min following i.v. administration of triplicate mice under dose escalation of 1–80 nmol is illustrated. The IC50 values of 20–30 μM were derived from fitting the results with R2 =0.58 and 0.6 for panels A and D. A value of p < 0.05 was determined for PEG-peptides 35 and 38 when comparing 1 and 80 nmol dose.
