I-6-Methyleneandrost-4-ene-3,17-Dione (1,2-Dihydro Exemestane) (CAS: 19457-55-7) iphakathi / ukungcola kwe-Exemestane (CAS: 107868-30-4).I-Exemestane iyi-steroid aromatase inhibitor engaphenduki.Isakhiwo sayo sifana naleso se-aromatase yemvelo engaphansi, i-androstenedione, futhi isebenza njenge-pseudosubstrate.I-estrogen yabesifazane bePostmenopausal iguqulwa ngokuyinhloko isuka ku-androgen (ekhiqizwe i-adrenal cortex) nge-aromatase esicutshini esizungezile.Lesi sidakamizwa sibophezela ngokungenakubuyiseleka endaweni esebenzayo ku-aromatase ukuze singasebenzi, ngaleyo ndlela ehle ngokuphawulekayo amazinga e-estrogen ekujikelezeni kwegazi kwabesifazane abangemva kokuya esikhathini.Ngokuvimbela i-aromatase ekwehliseni amazinga e-estrogen, ingasetshenziswa ukwelapha umdlavuza webele oncike ku-hormone kwabesifazane abangemva kokuya esikhathini.
