1951 – Mexican chemist Luis E. Miramontes conducts the very last step of the first synthesis of norethisterone, the progestin that would later be used in one of the first three oral contraceptives.
Norethisterone (NET), also known as norethindrone, is a medication that is used in combination with estrogen or alone in hormonal contraceptives, hormone replacement therapy, and in the treatment of gynecological disorders. It is a synthetic progestogen (or a progestin) of the 19-nortestosterone group and has similar effects to those of natural progesterone, including suppression of gonadotropins, ovulation inhibition, and endometrial transformation. In addition to its progestogenic activity, NET also has weak androgenic and estrogenic effects at high dosages. In addition to NET itself, several prodrugs of NET, such as norethisterone acetate (NETA), norethisterone enanthate (NETE), and others, have been marketed and have similar effects and uses.
