What is the mechanism of action of PAS?

We provide evidences that PAS is incorporated into the folate pathway by dihydropteroate synthase (DHPS) and dihydrofolate synthase (DHFS) to generate a hydroxyl dihydrofolate antimetabolite, which in turn inhibits DHFR enzymatic activity.

What are 5 aminosalicylic acid products?

There are several mesalamine-based oral 5-ASA agents including, Asacol® HD, Pentasa®, Lialda™, Apriso®, Delzicol™. These agents all use the same mesalamine, but differ in terms of the medication coating. Mesalamine must be coated or placed in special capsules to ensure drug delivery to the intestine or colon.

What is the antitubercular activity of aminosalicylic acid?

Aminosalicylic Acid is an analog of para-aminobenzoic acid ( PABA) with antitubercular activity. Aminosalicylic acid exerts its bacteriostatic activity against Mycobacterium tuberculosis by competing with PABA for enzymes involved in folate synthesis, thereby suppressing growth and reproduction of M. tuberculosis, eventually leading to cell death.
