Steroidal estrogens

Isolation and detection of steroids from human urine by molecularly imprinted solid-phase extraction and liquid chromatography

“…Androstenedione is converted by enzyme aromatase to 17␤-estradiol, estrone immediately or through testosterone or progesterone. In humans are produced naturally in both sexes, but woman have much higher concentration [1][2][3].…”

Unexpected discovery of estrone in the rotational spectrum of estradiol: a systematic investigation of a CP-FTMW spectrum

“…''Estrogen'' is a collective denomination for the natural hormones estrone, estradiol, and estriol. 1 They exist in males and females and are involved in both female and male reproduction, as well as the neuroendocrine, vascular, skeletal, and immune systems. Therefore, they are also implicated in different diseases and conditions such as infertility, obesity, osteoporosis, endometriosis, and a variety of cancers.…”

Total synthesis of steroids and heterosteroids from BISTRO

“…Among the various known analogues of steroids, heterosteroids have received much attention in view of their different and interesting biological activities demonstrated [72][73][74][75][76][77][78][79][80][81][82][83]. The replacement of one or more carbon atoms of a steroid molecule by a heteroatom affects chemical properties of the steroid and often results in useful alterations to its biological activity.…”
