PB2-IN-2 is an orally active PB2 inhibitor with RNA-dependent RNA Polymerase (RNP) IC50 = 0.2 nM, LRA (Ligand Receptor Assay) EC50 = 0.8 nM, Cytopathic Effect (CPE) EC50 = 0.1 nM. PB2-IN-2 exhibits broad-spectrum, nanomolar antiviral potency against a panel of influenza A strains (including H1N1pdm09, Lyon/1337/2007/H1N1, Tex12-Like/H3N2, PR/8/34/H1N1, WSN/1933/H1N1, rPR8(H1N1)/H7N9 with EC50 = 1.5, 3.6, 3.7, 13.8, 2.9 and 9.8 nM and all the CC50 values > 2 μM. PB2-IN-2 possesses an excellent pharmacokinetic profile and metabolic stability. PB2-IN-2 can be used for anti-influenza research.

PB2-IN-2 is an orally active PB2 inhibitor with RNA-dependent RNA Polymerase (RNP) IC50 = 0.2 nM, LRA (Ligand Receptor Assay) EC50 = 0.8 nM, Cytopathic Effect (CPE) EC50 = 0.1 nM. PB2-IN-2 exhibits broad-spectrum, nanomolar antiviral potency against a panel of influenza A strains (including H1N1pdm09, Lyon/1337/2007/H1N1, Tex12-Like/H3N2, PR/8/34/H1N1, WSN/1933/H1N1, rPR8(H1N1)/H7N9 with EC50 = 1.5, 3.6, 3.7, 13.8, 2.9 and 9.8 nM and all the CC50 values > 2 μM. PB2-IN-2 possesses an excellent pharmacokinetic profile and metabolic stability. PB2-IN-2 can be used for anti-influenza research[1].

In Vitro

PB2-IN-2 (compound 3) exhibits low lipophilicity (LogD 1.27)[1].
PB2-IN-2 has superior inhibitory activity against a range of wild-type and laboratory-adapted influenza A viruses (including H1N1pdm09, Lyon/1337/2007/H1N1, Tex12-Like/H3N2, PR/8/34/H1N1, WSN/1933/H1N1, rPR8(H1N1)/H7N9 with EC50= 1.5, 3.6, 3.7, 13.8, 2.9 and 9.8 nM and all the IC50 values > 2 μM) and good safety margin in A549 lung cells[1].

In Vivo

PB2-IN-2 (compound 3) demonstrates a high unbound plasma fraction in mouse (1.2%)[1].
PB2-IN-2 (0.05-1 mg/kg, p.o., twice daily for 5 days) has low efficacious dose, shallow efficacy cliff and wide therapeutic window in the mouse influenza A virus infection model[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
