clohexyl)-3-(p-tolyl)urea) are competitive inhibitors of ERAP1 aminopeptidase activity. Compound 3 (4-methoxy-3-(N-(2-(piperidin-1-yl)-5-(trifluoromethyl)phenyl)sulfamoyl)benzoic acid) allosterically activates ERAP1's hydrolysis of fluorogenic and chromogenic amino acid substrates but competitively inhibits its activity toward a nonamer peptide representative of physiological substrates.

the Janssen Jumpstarter library against the asexual stages of the P. falciparum parasite. Here we describe the structure activity relationship of the identified class and the optimisation of asexual stage activity while maintaining selectivity against the human HepG2 cell line. The most potent analogues from this study were shown to exhibit equipotent activityagainst P. falciparum multidrug resistant
A new series of selectively dichlorinated and dibrominated five- to eight-membered-ring [1,2-a]-fused benzimidazoles and [1,4]oxazino[4,3-a]benzimidazoles are synthesized in mostly high yields of >80% using the reaction of hydrogen peroxide and hydrohalic acid with commercially available o-cyclic amine substituted anilines. Domestic bleach with HCl can also be used for a one-pot ring closure and chlorination

The present invention provides: (1) antiviral agents that act by reducing or inhibiting the activity of SR proteins, more specifically, (i) antiviral agents that act by enhancing dephosphorylation of SR proteins, and (ii) antiviral agents that act by inhibiting proteins that phosphorylate SR proteins; (2) antiviral agents that act by inhibiting the expression of SR proteins, and (3) antiviral agents that act by activating proteins that antagonize SR proteins. The present invention also provides compounds that inhibit SRPKs, which phosphorylate SR proteins. Such compounds inhibit the activity of SR proteins and have antiviral activities. Various new viruses including SARS have emerged, and thus the present invention provides long-lasting broad-spectrum antiviral agents applicable to new viruses.
