Trimethoprim is a synthetic antimicrobial compound that serves as an antimetabolite within the same folic acid synthesis pathway as sulfonamides. However, trimethoprim is a structural analogue of dihydrofolic acid and inhibits a later step in the metabolic pathway (Figure \(\PageIndex{4}\)).:_Microbiology_(OpenStax)/ Patrick: An Introduction to Drug Synthesis.

Erythromycin A is a potent antibiotic long-recognized as a therapeutic option for bacterial infections. The soil-dwelling bacterium Saccharopolyspora erythraea natively produces erythromycin A from a 55 kb gene cluster composed of three large polyketide synthase genes (each ∼10 kb) and 17 additional genes responsible for deoxysugar biosynthesis, macrolide tailoring, and :// Erythromycin A was isolated in from Saccharopolyspora erythraea.

3 The structure was elucidated by classical methods 4 and confirmed by X-ray crystallography. 5 Other members of the family occur as biosynthetic intermediates and so will be presented in that context later. Erythromycin A is an important antibiotic widely used in clinical medicine against infections caused by Gram-positive Pateamine A is a naturally occurring metabolite extracted from the marine sponge Mycale hentscheli.
