Bioactivity | Trimethoprim is a bacteriostatic antibiotic and an orally active dihydrofolate reductase inhibitor. Trimethoprim is active against a wide range of Gram-positive and Gram-negative aerobic bacteria. Trimethoprim has the potential for the research of urinary tract infections, Shigellosis and Pneumocystis pneumonia. Trimethoprim can inhibit infection of Influenza A virus in chick embryo when combinated with zinc[1][2][3][4]. | ||||||||||||
Invitro | Trimethoprim interrupts folate metabolism by inhibition of the activity of dihydrofolase reductase (DHFR), which reduces dihydrofolate to tetrahydrofolate (THF)[1].Trimethoprim (3 μg/mL; 1 h) induces protein aggregation and main heat shock proteins (Hsps) in E. coli cells, which indicates that Trimethoprim sulfate presence leads to protein misfolding[1].Trimethoprim (1.5-3 μg/mL; 1 h) causes induction of DnaK, DnaJ, GroEL, ClpB, and IbpA/B Hsps in E. coli cells exposed to folate and heat stress[1]. | ||||||||||||
