Abstract: Lovastatin, the first statin drug approved by the FDA in 1987, is a potent drug used in the treatment of cardiovascular disease by reducing the levels of low-density lipoproteins (LDL), the so-called bad cholesterol. It also plays an important role in the treatment of Alzheimerand#8223;s disease, cancer and renal diseases. The study of biochemical pathways in A. terreus will provide knowledge on byproduct reduction and redirecting the flux flow through improved lovastatin production. Aspergillus terreus ATCC 20542 is widely used in industry for the production of lovastatin, but the whole genome sequence is not fully analyzed. So the computational analysis of pathways and interaction networks was done for A. terreus strain NIH2624 whose whole genome sequence is publicly available. The clues obtained from the sequence analysis of strain NIH2624 can be utilized to increase the yield of lovastatin. The protein interaction network analysis was done to determine the interacting partners of lovastatin biosynthetic cluster proteins and validation. The validation of the clues obtained from the above analysis was confirmed in the wet laboratory, and the results obtained were in accordance with the computational result. Sodium pyruvate, used as an inhibitor of isocitrate lyase increased the production of lovastatin from 0.95and#956;g/ml to 9.68and#956;g/ml. Calcium chloride, an inhibitor of 6-methyl salicylic acid synthase (precursor of patulin) increased the production of lovastatin from 0.95and#956;g/ml to 5.8and#956;g/ml. Sodium oxalate, an inhibitor of lactate dehydrogenase reduced the production of lovastatin from 0.95and#956;g/ml to 0.67and#956;g/ml. newline newline newline
