[{"from": "human", "value": "Could you give me a brief overview of this molecule? [C][C][=Branch1][C][=O][O].[C][=C][C][=Branch1][Branch2][=C][C][=C][Ring1][=Branch1][C][N][S][=Branch1][C][=O][=Branch1][C][=O][N]"}, {"from": "gpt", "value": "The molecule is the acetate salt form of mafenide, a synthetic sulfonamide analog of para-aminobenzoic acid (PABA) with topical anti-infective activity. Mafenide acetate competes with PABA for the bacterial enzyme dihydropteroate synthase, thereby preventing the incorporation of PABA into dihydrofolic acid, thereby interferes with normal folic acid metabolism. As a result, de novo synthesis of pyrimidines, which requires folate metabolites, is impeded and subsequently DNA synthesis is affected. Mafenide acetate is bacteriostatic against many gram-negative and gram-positive organisms, including Pseudomonas aeruginosa and certain strains of anaerobes."}]
