mRNA Inhibitor

Trecovirsen (GEM91) is an antiviral agent targeting HIV gag mRNA, which hybridizes with complementary HIV gag mRNA at the initiation site. Trecovirsen induces a reversible, dose-dependent prolongation of activated partial thromboplastin time via its polyanionic property. Trecovirsen is applicable to research related to HIV infection.

KKL-55 is a broad-spectrum antibacterial agent that inhibits the trans-translation pathway and the ClpXP protease. KKL-55 suppresses trans-translation of non-stop mRNA, interferes with the binding of EF-Tu to tmRNA, and inhibits the proteolysis of substrates by ClpXP. KKL-55 blocks spore germination of Bacillus anthracis and protects macrophages from damage induced by anthrax toxin. By virtue of its inhibitory effect on ClpXP, KKL-55 synergistically enhances the antibacterial activity of antibiotics against drug-resistant Staphylococcus aureus. KKL-55 can be used in studies related to bacterial infections.

AN11736 is a CPSF3 inhibitor. AN11736 exerts a potent anti-trypsin effect by specifically inhibiting the activity of the trypanosome CPSF3 endonuclease, disrupting the mRNA maturation process. AN11736 exhibits IC₅₀s against T. congolense and T. vivax of 0.14 and 1.3 nM, respectively. AN11736 exhibits strong anti-trypsin activity in mouse and cattle models.
