Effect of betulinic acid and its ionic derivatives on MuLV replication. (A) 43D cells were treated with 30 μM of the compounds for 48 hrs, and Gag proteins in cells and media were detected by western blots using the rabbit serum for anti-p30CA. (B) The intensity of Gag signals detected by western blots was quantified by immunodensitometry and the viral release efficiency was calculated. The figure shows the relative virus release efficiency (% Gag release) with standard deviation.
