<p>1,3-Dibenzoic acid esters of 17 alpha -ethynyl-7 alpha -methyl-1,3,5(10)-estratriene-1,3,17 beta -triol possess strong estrogenic and ovulation-inhibiting activities. As compared to the corresponding diacetic acid ester, these dibenzoic acid esters remain stable over 2-7 months even in the desired, low dosage at a thermal load of up to 60 DEG C.</p> |
