Losartan Carboxaldehyde Chemische Eigenschaften,Einsatz,Produktion Methoden

Beschreibung
Losartan carboxaldehyde is an intermediate aldehyde metabolite of the angiotensin II type 1 receptor antagonist, losartan . It does not block angiotensin receptors, but instead inhibits endothelial cyclooxygenase (COX)-2 expression, thereby exerting anti-inflammatory actions. At 1 μM in vitro, losartan carboxaldehyde has also been shown to block the upregulation of intercellular adhesion molecule (ICAM)-1 mRNA and COX-dependent generation of thromboxane A₂ and prostaglandin F_2α . Losartan carboxaldehyde can also act as a partial agonist (EC₅₀ = 17.1 μM) of the insulin-sensitizing peroxisome proliferator-activated receptor γ in vitro.

in vitro
losartan is an intermediate aldehyde metabolite of losartan, the angiotensin ii type 1 receptor antagonist. losartan could not block angiotensin receptors, but inhibit the expression of endothelial cyclooxygenase (cox)-2, therefore exerting anti-inflammatory actions. moreover, losartan at 1 μm was able to block the upregulation of icam-1 mrna and cox-dependent generation of thromboxane a2 and prostaglandin f2α [1].
in vivo
in animal stufdy, losartan was infused for 10 days to rats on a normal sodium intake (nna) and rats on a high sodium intake (hna) to suppress endogenous ang ii. although basal plasma renin activity was markedly suppressed in hna rats compared with nna rats, control arterial pressure was not different between nna and hna rats. losartan could decrease arterial pressure from control levels in nna rats on the first day of infusion but had no effect on arterial pressure in hna rats. in addition, by day 10 of losartan infusion, arterial pressure had decreased further from control levels in nna rats but remained unchanged compared with control in hna rats [2].
