The synthesis and characterization of some novel Pyrimidine derivatives have been presented. Acylation of resorcinol followed by nuclear prenylation with isoprene gives Chroman. Chroman on treatment with p-substituted benzaldehydes affords substituted chalcones. Pyrimidines have been prepared from chalcones by condensing with Guanidine hydrochloride in alkali medium. The structure of Pyrimidine...

Three different prenyltransferases attach isoprenyl anchors to C-terminal motifs in substrate proteins. These lipid anchors serve for membrane attachment or protein-protein interactions in many pathways. Although well-tolerated selective prenyltransferase inhibitors are clinically available, their mode of action remains unclear since the known substrate sets of the various prenyltransferases ar...

Statins are cholesterol-lowering drugs that inhibit 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase, the rate-limiting enzyme in the synthesis of cholesterol via the mevalonate pathway. This pathway also produces coenzyme Q (a component of the respiratory chain), dolichols (important for protein glycosylation), and isoprenoids (lipid moieties responsible for the membrane association of smal...
