The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 2-Chloronicotinoyl chloride(SMILESS: O=C(Cl)C1=CC=CN=C1Cl,cas:49609-84-9) is researched.HPLC of Formula: 31181-89-2. The article 《Discovery of Novel Pyrimidine-Based Capsid Assembly Modulators as Potent Anti-HBV Agents》 in relation to this compound, is published in Journal of Medicinal Chemistry. Let’s take a look at the latest research on this compound (cas:49609-84-9).
In this study, novel potent pyrimidine derivatives I (R1 = SMe, SO2Me; R2 = [2-(pyridin-3-ylformamido)ethyl]aminyl, 3-Cl-4-FC6H3NH, 4-aminopiperidin-1-yl, etc.; R3 = [4-(morpholin-4-yl)phenyl]aminyl, C6H5NH, 3-Br-4-FC6H3NH, etc.) as core assembly modulators were synthesized and their antiviral effects were evaluated in in vitro and in vivo biol. experiments One of the synthesized derivatives, compound I (R1 = SO2Me; R2 = 4-aminopiperidin-1-yl; R3 = 3-Cl-4-F-C6H3NH) displayed potent inhibitory effects in the in vitro assays (52% inhibition in the protein-based assay at 100 nM and an IC50 value of 181 nM in the serum HBV DNA quantification assay). Moreover, treatment with compound I (R1 = SO2Me; R2 = 4-aminopiperidin-1-yl; R3 = 3-Cl-4-F-C6H3NH) for 5 wk significantly decreased serum levels of HBV DNA levels (3.35 log reduction) in a human liver-chimeric uPA/SCID mouse model, and these effects were significantly increased when I (R1 = SO2Me; R2 = 4-aminopiperidin-1-yl; R3 = 3-Cl-4-F-C6H3NH) was combined with tenofovir, a nucleotide analog inhibitor of reverse transcriptase used for the treatment of HBV infection.
