Antitumor activity on line 10 hepatoma in strain 2 guinea pigs and pharmaceutical properties of quinonyl-MDP preparations.
The pharmaceutical properties of quinonyl-MDP-66 were discussed with special reference to the stability of oil-in-water emulsion, distribution capacity into regional lymph nodes and tumor regressive activity. The oil-in-water emulsion of quinonyl-MDP-66, which was prepared by treatment of quinonyl-MDP-66 with squalane (25 x) and emulsified with aqueous solution of 5% HCO-60 and 5.6% d-mannitol, was kept in lyophylized state and used after reconstitution by the addition of water before use. The reconstituted suspension of quinonyl-MDP-66 in oil-in-water emulsion was stable for more than 24 hrs. The oil-in-water emulsion of quinonyl-MDP-66 as prepared above was effective for the distribution of quinonyl-MDP-66 into regional lymph node in rats and for the regression of line 10 hepatoma in strain 2 guinea pigs by intralesional injection.
