Mevastatin (compactin, ML-236B) is a hypolipidemic agent that belongs to the statins class.
It was isolated from the mold Penicillium citrinum by Akira Endo in the 1970s, and he identified it as a HMG-CoA reductase inhibitor,[1] i.e., a statin. Mevastatin might be considered the first statin drug;[2] clinical trials on mevastatin were performed in the late 1970s in Japan, but it was never marketed.[3] The first statin drug available to the general public was lovastatin.
Mevastatin has since been derivatized to the compound pravastatin, which is a pharmaceutical used the in lowering cholesterol and preventing cardiovascular disease.
In vitro, it has antiproliferative properties.[4]
A British group isolated the same compound from Penicillium brevicompactum, named it compactin, and published their results in 1976.[5] The British group mentions antifungal properties with no mention of HMG-CoA reductase inhibition.
High doses inhibit growth and proliferation of melanoma cells.[6]
Biosynthesis
Biosynthesis of mevastatin is primarily accomplished via a type 1 PKS pathway it proceeds in the PKS pathway as seen in figure 1 until it reaches a hexaketide state where it undergoes a Diels-Alder cyclization. After cyclization it continues via the PKS pathway to a nonaketide after which it is released and undergoes oxidation and dehydration. It is presumed that the oxidations are preformed by a polypeptide that is similar to cytochrome p450 monooxygenase, which is encoded by mlcC within the mevastatin gene. Lastly the biosynthesis is completed by the PKS facilitating the addition of a diketide sidechain and a methylation by SAM.[7] Figure 1 shows mevastatin in its acid form but it can also be in the more commonly seen lactone form. This pathway was first observed in Penicillium cilrinum and was later discovered that another type of fungus, Penicillium brevicompaetum also produced mevastatin via a PKS pathway.
