Synthetic Route of C5H5FN2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-Amino-2-fluoropyridine, is researched, Molecular C5H5FN2, CAS is 1827-27-6, about Soluble-type small-molecule CD4 mimics as HIV entry inhibitors.

Several small mol. CD4 mimics have been reported previously as HIV-1 entry inhibitors, which block the interaction between the Phe43 cavity of HIV-1 gp120 and the host CD4. Known CD4 mimics such as NBD-556 possess significant anti-HIV activity but are less soluble in water, perhaps due to their hydrophobic aromatic ring-containing structures. Compounds with a pyridinyl group in place of the Ph group in these mols. have been designed and synthesized in an attempt to increase the hydrophilicity. Some of these new CD4 mimics, containing a tetramethylpiperidine ring show significantly higher water solubility than NBD-556 and have high anti-HIV activity and synergistic anti-HIV activity with a neutralizing antibody. The CD4 mimic that has a cyclohexylpiperidine ring and a 6-fluoropyridin-3-yl ring has high anti-HIV activity and no significant cytotoxicity. The present results will be useful in the future design and development of novel soluble-type mol. CD4 mimics.
