I-6-Methyleneandrost-4-ene-3,17-Dione (1,2-Dihydro Exemestane) (i-CAS: 19457-55-7) yindawo ephakathi / engcolileyo ye-Exemestane (CAS: 107868-30-4).I-Exemestane yi-steroid aromatase inhibitor engenakuguqulwa.Ubume bayo bufana ne-aromatase yendalo ye-substrate, i-androstenedione, kwaye isebenza njenge-pseudosubstrate.I-estrogen yabasetyhini bePostmenopausal iguqulwa ikakhulu kwi-androgen (eveliswa yi-adrenal cortex) nge-aromatase kwiithishu ezingqongileyo.Eli chiza libophelela ngokungenakujikwa kunye nendawo esebenzayo kwi-aromatase ukuze lingasebenzi, ngoko ke asezantsi kakhulu amanqanaba e-estrogen kumjikelezo wegazi wabasetyhini abasemva kokuya exesheni.Ngokunqanda i-aromatase ukuthoba amanqanaba e-estrogen, ingasetyenziselwa ukunyanga umhlaza webele oxhomekeke kwihomoni kubasetyhini be-postmenopausal.
