Azalanstat is a synthetic imidazole. It has been shown to inhibit cholesterol synthesis in HepG2 cells, human fibroblasts, hamster hepatocytes and hamster liver, by inhibiting the cytochrome P450 enzyme lanosterol 14 alpha-demethylase. In hamsters it lowered serum cholesterol in a dose-dependent manner. Azalanstat preferentially lowered low density lipoprotein (LDL) cholesterol and apo B relative to high density lipoprotein (HDL) cholesterol and apo A-1. Azalanstat inhibited hepatic microsomal hydroxymethylglutaryl-CoA (HMG-CoA) reductase activity in hamsters in a dose-dependent manner and this was highly correlated with serum cholesterol lowering. In vitro studies with HepG2 cells indicated that this modulation of reductase activity was indirect, occurring at a post-transcriptional step. Azalanstat has been in preclinical phase for the treatment of hyperlipidaemia but this research has been discontinued.
