Synthases/Synthetases

Synthase and synthetase inhibitors block enzymes that build nucleotides, cell wall polymers and lipids. Thymidylate synthase supplies thymidine nucleotides for DNA replication and is a classic target of antifolate compounds. Raltitrexed was reported in 1991 as a quinazoline antifolate inhibitor of this enzyme, and Nolatrexed Dihydrochloride is a further example. Caspofungin, micafungin and anidulafungin are echinocandins that inhibit fungal 1,3-β-D-glucan synthase. In Candida albicans, a glucan synthase subunit gene was identified in 1997 as the essential target of these inhibitors. Other compounds act on lipid synthesis, such as the squalene synthase inhibitor YM-53601. Triacsin C inhibits long-chain acyl-coenzyme A (acyl-CoA) synthetases, which activate fatty acids for further metabolism.
