Customer Review

Based on 1 Customer Validation

3-Methylthiophene-2-carboxylic acid (compound 3) is a potent Pseudomonas quinolone signal system protein E (PqsE) inhibitor with a Kd of 19.6 µM and an IC50 of 40 µM. 3-Methylthiophene-2-carboxylic acid binds to the active center of PqsE and shows inhibition of the thioesterase activity. Methylthiophene-2-carboxylic acid can permeate into P. aeruginosa and affect 2,4-dihydroxyquinoline (DHQ) levels to a similar extent as deletion of the PqsE gene. 3-Methylthiophene-2-carboxylic acid can be used for cystic fibrosis research.
