CAS tus lej 112809-51-5 yog tus lej cim tshwj xeeb uas tau muab los ntawm Chemical Abstracts Service (CAS) rau Letrozole, cov tshuaj siv dav hauv kev kho mob qog noj ntshav ntawm lub mis. CAS tus lej raug lees paub thoob ntiaj teb thiab ua tus qauv txheej txheem ntawm kev txheeb xyuas cov tshuaj lom neeg.
Chemical Abstracts Service, ib feem ntawm American Chemical Society, muab cov lej no rau txhua yam tshuaj uas tau piav qhia hauv cov ntaub ntawv, kom ntseeg tau tias tus cim tshwj xeeb rau txhua yam khoom. Cov txheej txheem no tso cai rau kev txheeb xyuas qhov tseeb thiab kev txheeb xyuas cov tshuaj sib xyaw ua ke, ua kom yooj yim rau kev tshawb fawb, kev tswj hwm kev tswj hwm, thiab kev sib txuas lus thoob plaws ntau yam kev qhuab qhia.
Letrozole, txheeb xyuas los ntawm CAS naj npawb 112809-51-5, yog ib qho aromatase inhibitor siv los kho cov tshuaj estrogen receptor-zoo mob qog noj ntshav mis hauv cov poj niam postmenopausal. Los ntawm kev thaiv cov enzyme aromatase, Letrozole txo cov tshuaj estrogen, uas tuaj yeem ua rau muaj kev loj hlob ntawm qee yam mob qog noj ntshav.
