Cytochrome p450 comprises a superfamily of heme-thiolate proteins named for the spectral absorbance peak of their carbon-monoxide-bound species at 450 nm. Having been found in every class of organism, including Archaea, the p450 superfamily is believed to have originated from an ancestral gene that existed over 3 billion years ago. Repeated gene duplications have subsequently given rise to one of the largest of multigene families. These enzymes are notable both for the diversity of reactions that they catalyze and the range of chemically dissimilar substrates upon which they act. Cytochrome p450s support the oxidative, peroxidative and reductive metabolism of such endogenous and xenobiotic substrates as environmental pollutants, agrochemicals, plant allelochemicals, steroids, prostaglandins and fatty acids. In humans, Cytochrome p450s are best known for their central role in phase I drug metabolism where they are of critical importance to two of the most significant problems in clinical pharmacology: drug interactions and interindividual variability in drug metabolism.

    SKF 104976
    		Inhibitor
    SKF 104976 is a 3,2-carboxylic acid derivative with potent 14-alpha-demethylase (14 alpha DM) inhibitory activity. SKF 104976 inhibited 14 alpha DM activity by 50% at 2 nM in Hep G2 cell extracts. SKF 104976 inhibited the incorporation of [14C]acetate into cholesterol in intact cells at similar concentrations, accompanied by accumulation of lanosterol, and resulted in a 40-70% decrease in 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) activity. SKF 104976 did not affect the uptake and degradation of low-density lipoprotein in Hep G2 cells, indicating that HMGR and low-density lipoprotein receptor activities are not coordinately regulated under these conditions. The inhibitory effect of SKF 104976 on HMGR activity remained unchanged even when the flux of carbon units in the sterol synthesis pathway was reduced by 80%. SKF 104976 did not inhibit HMGR activity under conditions where sterol synthesis was almost completely blocked by lovastatin.
