PB2-IN-2

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 .

Carboxymethyl-β-cyclodextrin sodium salt is a negatively charged β-cyclodextrin derivative, as well as a metal ion chelator and solubilizing reagent. Carboxymethyl-β-cyclodextrin sodium salt forms stable aqueous complexes with Ba ²⁺, Ca ²⁺, Cd ²⁺, Ni ²⁺, Pb ²⁺, Sr ²⁺, and Zn ²⁺ ions. Carboxymethyl-β-cyclodextrin sodium salt derived hydrogel carriers support oral insulin delivery via paracellular permeation across Caco-2 monolayers and produce sustained hypoglycemic effects in diabetic mice. Carboxymethyl-β-cyclodextrin sodium salt can be conjugated onto folate-modified BSA nanoparticles to boost folate receptor-mediated endocytosis, elevate intracellular anticancer drug uptake and trigger cell apoptosis. Carboxymethyl-β-cyclodextrin sodium salt can be utilized for chiral separation in capillary electrophoresis, development of nanoscale drug carriers and nucleic acid transfection research .

HAA-09 is an orally active and potent anti-influenza agent, targeting the influenza PB2_cap binding domain. HAA-09 displays potent anti-influenza A virus activity, with an EC₅₀ of 0.03 μM. HAA-09 shows polymerase inhibition, with an IC₅₀ of 0.06±0.004 μM. HAA-09 blocks virus replication without causing obvious cytotoxicity .
