Letrozole CAS: 112809-51-5 Chaw Tsim Khoom Siv

Letrozole yog ib feem ntawm tiam tshiab ntawm cov tshuaj aromatase inhibitors uas xaiv tau zoo heev thiab yog ib qho tshuaj benzotriazole derivative uas tsim los ntawm tes. Letrozole inhibits aromatase kom txo cov tshuaj estrogen, yog li tiv thaiv estrogen los ntawm kev txhawb nqa kev loj hlob ntawm qog. Nws cov haujlwm hauv vivo muaj zog dua li thawj tiam aromatase inhibitor Amarante 150-250 npaug. Vim nws xaiv tau zoo heev, nws yuav tsis cuam tshuam rau glucocorticoid, mineralocorticoid thiab thyroid ua haujlwm; txawm tias noj ntau npaum li cas los xij, nws yuav tsis muaj kev cuam tshuam rau adrenal corticosteroid secretion, ua rau nws muaj cov txiaj ntsig kho mob siab.

Daim Ntawv Thov thiab Cov Nyhuv

Letrazole tuaj yeem tsim ua ob kauj ruam los ntawm 4-bromomethyl-benzonitrile nrog 1,2,4-triazole thiab yog lub cim thib peb aromatase inhibitor. Nws yog ib qho inhibitor tshwj xeeb ntawm P450arom uas tiv thaiv kev hloov pauv ntawm androstenedione mus rau estrone. Kev txo qis ntawm plasma estrogen yog tam sim ntawd thiab kav ntev. Qhov no ua tiav yam tsis muaj kev txwv ntawm lwm cov tshuaj steroid biosynthesis ua rau nws yog qhov xaiv tshaj plaws aromatase inhibitor sim. Letrazole muaj kev ua haujlwm tiv thaiv qog zoo kawg nkaus, raug zam zoo thiab tsis muaj kev phiv tshuaj lom. Nws muaj zog dua 10,000 npaug ntau dua li aminoglutethimide, hauv vivo, thawj lub aromatase inhibitor uas tau tsim zoo.
