Azalanstat
Based on 1 Customer Validation
Azalanstat (RS-21607) is an orally active lanosterol 14α-demethylase inhibitor. Azalanstat exerts a cholesterol-lowering effect by inhibiting cholesterol synthesis and regulating HMG-CoA Reductase (HMGCR), and shows an additive effect when used in combination with Cholestyramine (HY-104081). Azalanstat is used in the study of hypercholesterolemia.

Description
In Vitro
Azalanstat (0.01-100 μM; 20 h) exerts a biphasic regulatory effect on HMG-CoA reductase activity in HepG2 cells: it inhibits approximately 40% of the enzyme activity at concentrations of 0.01-1 μM, and stimulates enzyme activity up to 600% at concentrations of 30-100 μM[1].
Azalanstat (0.1-5 μM; 18 h) increases HMG-CoA reductase mRNA levels by 300% at 0.1 μM and by 100% at 5 μM in HepG2 cells, and elevates LDL receptor mRNA levels by 70% at both 0.1 μM and 5 μM, suggesting post-transcriptional regulation of HMG-CoA reductase activity[1].
Azalanstat (0.1-10 μM; 24 h pre-incubation, 3 h LDL uptake) increases specific 125I-LDL uptake by approximately 25% in HepG2 cells[1].

Cell Line:human fibroblasts, HepG2 cells, hamster hepatocytes
-
Concentration:0.1, 1.0, 10, 100, 1000, 10000 nM
-
Incubation Time:1 hr pre-incubation, 2 hr pulse
-
Result:Inhibited cholesterol synthesis in human fibroblasts (IC50 = 0.2 nM), HepG2 cells (IC50 = 6.5 nM), and hamster hepatocytes (IC50 = 10 nM) by blocking lanosterol 14α-demethylase.
In Vivo
Azalanstat (50 mg/kg; oral; once daily; for 28 days) reduces plasma cholesterol by 37% in hamsters fed a high-fat/high-cholesterol diet, and its effect is transiently maintained after drug withdrawal[1].
Azalanstat (50 mg/kg; oral; once daily; for 14 consecutive days) inhibits cholesterol synthesis in hamster tissues by up to 98%. It exhibits no selectivity in tissue distribution and also elevates methyl sterol levels, particularly dihydrolanosterol levels in the liver[1].
Azalanstat (25-100 mg/kg; oral; daily; 14 days) inhibits hepatic microsomal HMG-CoA reductase activity in a dose-dependent manner in hamsters, with an ED50 of 31 mg/kg, and this activity is highly correlated with serum cholesterol reduction[1].
Azalanstat (50-75 mg/kg; oral; daily; for 1-2 weeks) increases hepatic cholesterol 7α-hydroxylase activity in hamsters by 1.5- to 5-fold, and this effect emerges after 1-2 weeks of oral administration at a dose of 50-75 mg/kg[1].
Azalanstat (30 mg/kg; p.o.; once daily; for 7 consecutive days) reduces serum cholesterol in hamsters by 44% and inhibits hepatic HMG-CoA reductase activity; its cholesterol-lowering effect exerts a synergistic effect with Cholestyramine (HY-104081), and it also attenuates Cholestyramine-induced activation of HMG-CoA reductase[1].
Azalanstat (50 mg/kg; oral; daily; 7-10 days) reduces liver-specific LDL binding capacity and LDL receptor protein expression levels in hamsters, while lowering serum cholesterol by up to 53%[1].
