A nucleic acid inhibitor is a type of antibacterial that acts by inhibiting the production of nucleic acids. There are two major classes: DNA inhibitors and RNA inhibitors. [ 1 ] The antifungal flucytosine acts in a similar manner.
PCR inhibitors are any factor which prevent the amplification of nucleic acids through the polymerase chain reaction (PCR). [1] PCR inhibition is the most common cause of amplification failure when sufficient copies of DNA are present. [2] PCR inhibitors usually affect PCR through interaction with DNA or interference with the DNA polymerase.
Dihydropteroate synthase inhibitors are drugs that inhibit the action of dihydropteroate synthase. They include sulfonamides, dapsone, and para-aminosalicylic acid. [1] Tetrahydrofolate synthesis pathway. In bacteria, antibacterial sulfonamides act as competitive inhibitors of the enzyme dihydropteroate synthase, DHPS.

As a nucleoside inhibitor, the guanosine analog prodrug is used to stop viral RNA synthesis and viral mRNA capping by incorporating into RNA and pairing to uracil or cytosine. Branaplam is currently in phase I/II clinical trial for the treatment of Spinal Muscular Atrophy (SMA). This molecule is from a class of pyridazine small molecules and ...
A locked nucleic acid phosphorothioate antisense molecule, termed SPC2996, has been developed to target the mRNA coding for Bcl-2 oncoprotein, a protein that inhibits apoptosis in chronic lymphocytic leukemia cells (CLL). Phase I and II clinical trials demonstrated a dose dependent reduction in circulating CLL cells in approximately 30% of the ...
It is nonenzymatically cleaved to mercaptopurine, a purine analogue that inhibits DNA synthesis. By preventing the clonal expansion of lymphocytes in the induction phase of the immune response, it affects both cell immunity and humoral immunity .
Competition for the binding sites of enzymes that participate in essential biosynthetic processes and subsequent incorporation of these biomolecules into nucleic acids, inhibits their normal tumor cell function and triggers apoptosis, the cell death process. Because of this mode of action, most antimetabolites have high cell cycle specificity ...
