WebMechanism of action: Sulfonamides structurally resemble p-aminobenzoic acid (PABA), a precursor in bacterial DHF synthesis. As false substrates, sulfonamides competitively inhibit utilization of PABA, and hence DHF synthesis. Because most bacteria cannot take up exogenous folate, they are depleted of DHF. Trimethoprim: WebThe sulfamethoxazole component inhibits the formation of dihydrofolic acid from para-aminobenzoic (PABA), whereas trimethoprim inhibits dihydrofolate reductase. Both drugs block folic acid synthesis, preventing bacterial cell synthesis of essential nucleic acids. Doxycycline Mechanism of Action
