摘要:
Prostaglandins of the formula ##SPC1##Wherein R.sub.1 is HOCH.sub.2, --COOH, a salt thereof or an ester thereof; R.sub.2 is OH; and R.sub.3 is H or R.sub.2 and R.sub.3 collectively are = O. A is --CH.sub. 2 --CH.sub.2 -- or --(trans)--CH=CH--, B is --CH.sub. 2 CH.sub.2 --or --(cis)--CH=CH-- and R.sub.4 --O--O--R.sub.5 is a ketal group, are superior in physiological activity to the corresponding 15-.alpha.-hydroxy-prostaglandins.
