Abstract:
A fungal strain able to naturally accumulate large amounts of monacolin J was improved by N-methyl-N'-nitro-N-nitrosoguanidine mutagenesis and genetic disruption of the lovF gene. Semisynthesis was then used to produce novel statins by attaching different side chains at the C8 hydroxyl residue. In vitro hypocholesterolemic and neuroprotection assays showed that one derivative (NST0037) had a very low 3-hydroxy-3-methylglutaryl CoA reductase IC(50) and high protection rate for oxidative-stress-induced neuron cell death.
