khoom Introduction
Acitretin API yog dab tsi?
Acitretin API, yog ib qho tshuaj ua los ntawm vitamin A, tseem hu ua all-trans retinoic acid los yog betarretin A. Nws tswj ntau npaum li cas ntawm daim tawv nqaij proliferate thiab sib txawv thaum tseem cuam tshuam li cas lub stratum corneum tsim. Nws txhim kho cov kab mob xws li keratosis, txo pob txuv, thiab tswj cov tawv nqaij pigmentation los ntawm kev txuas mus rau vitamin A acid receptor nyob rau hauv lub nucleus ntawm cov hlwb thiab hloov cov noob transcription thiab protein qhia. Nrog rau qhov hnyav molecular ntawm 326.43 g / mol thiab cov tshuaj formula C21H26O3, nws feem ntau siv cov xim daj los yog crystalline hmoov. Nws muaj tus lej CAS 55079-83-9. Hexane tuaj yeem siv los ua kom ruaj khov, thiab nws cov ntsiab lus melting yog 228 - 230 ° C. LD50 los ntawm kev txhaj tshuaj intraperitoneal yog li ntawm> 4000 mg / kg (1 hnub) txog 700 mg / kg (10 hnub thiab 20 hnub), raws li kev tshawb nrhiav ntawm cov tshuaj lom neeg mob hnyav hauv cov nas. Lub active metabolite ntawm tretinoin yog acitretin, ib tug synthetic qab zib counterpart ntawm vitamin A. Ntxiv nrog rau lwm yam tawv nqaij mob, nws yog siv los kho mob hnyav psoriasis thiab keratosis.
