  • Method of preparing prostaglandin B.sub.1 derivatives
    Patent number: 4245111
    Abstract: An improved method for synthesizing and purifying PGB.sub.x, a mixture of lymers of prostaglandin B.sub.1. PGB.sub.x activity is assayed by measuring the minimum amount of PGB.sub.x required to restore complete phosphorylation ability to isolated rat liver mitochondria, first aged and degraded to the point where they exhibit less than 5% of the phosphorylating ability of normal mitochondria. A higher and more reproducible yield of PGB.sub.x of improved quality have been produced thereby.
