LCZ696(Sacubitril + Valsartan)
Kufotokozera
LCZ696 (Sacubitril/Valsartan), yopangidwa ndi Valsartan (an ARB) ndi Sacubitril (AHU377) mu 1: 1 molar ratio, ndi kalasi yoyamba, pakamwa bioavailable, ndi awiri-acting angiotensin receptor-neprilysin (ARN) inhibitor kwa hypertension. ndi kulephera kwa mtima [1] [2] [3]. LCZ696 imathandizira matenda a shuga a cardiomyopathy poletsa kutupa, kupsinjika kwa okosijeni ndi apoptosis.
Mbiri
LCZ696 ndi yoyamba mu kalasi ya ARNi (angiotensin receptor neprilysin inhibitor) yomwe imakhala ndi anionic moieties ya AR valsartan ndi neprilysin inhibitor prodrug AHU377 (1: 1 chiŵerengero) cha kulephera kwa mtima ndi matenda oopsa.
Ma angiotensin receptors ndi G-protein-coupled receptors. Amayimira pakati pamtima ndi zotsatira zina za angiotensin II yomwe ndi bioactive peptide ya renin-angiotensin system. Neprilysin ndi endopeptidase yopanda ndale yomwe imawononga ma peptides amkati a vasoactive monga natriuretic peptides. Kuletsa kwa neprilysin kumawonjezera kuchuluka kwa ma peptides a natriuretic omwe adathandizira kuteteza mtima, mitsempha ndi aimpso. [1]
Mu makoswe a Sprague-Dawley, kuwongolera pakamwa kwa LCZ696 kunapangitsa kuti pakhale kukwera kodalira kwa mlingo wa immunoreactivity wa peptide ya atrial natriuretic chifukwa cha kuletsa kwa neprilysin. Mu makoswe amtundu wapawiri wa transgenic, LCZ696 idayambitsa kudalira kwa mlingo komanso kuchepa kwapang'onopang'ono kwapakati. Ophunzira athanzi, kafukufuku wopangidwa mwachisawawa, wakhungu kawiri, woyendetsedwa ndi placebo adatsimikizira kuti LCZ696 idapereka inhibition ya neprilysin nthawi yomweyo ndi blockade ya AT1 receptor. LCZ696 inali yotetezeka komanso yololera bwino mwa anthu. [2] [3]
