great influence on hormonal activity and esterase hydrolysis. Formateesters at 7alpha and 15alpha were good estrogens, but lengthening the chain to acetate dramatically decreased hormonal activity. However, the 7alpha-formate esters were not enzymatically hydrolyzed. At 11beta, the acetate (methyl ester) was an effective estrogen, but increasing the chain length to propionate dramatically reduced hormonal
