About: Abstract We describe here the design, synthesis and biological evaluation of a series of molecules toward the development of novel peptidomimetic inhibitors of SARS-CoV 3CLpro. A docking study involving binding between the initial lead compound 1 and the SARS-CoV 3CLpro motivated the replacement of a thiazole with a benzothiazole unit as a warhead moiety at the P1′ site. This modification led to the identification of more potent derivatives, including 2i, 2k, 2m, 2o, and 2p, with IC50 or K i values in the submicromolar to nanomolar range. In particular, compounds 2i and 2p exhibited the most potent inhibitory activities, with K i values of 4.1 and 3.1nM, respectively. The peptidomimetic compounds identified through this process are attractive leads for the development of potential therapeutic agents against SARS. The structural requirements of the peptidomimetics with potent inhibitory activities against SARS-CoV 3CLpro may be summarized as follows: (i) the presence of a benzothiazole warhead at the S1′-position; (ii) hydrogen bonding capabilities at the cyclic lactam of the S1-site; (iii) appropriate stereochemistry and hydrophobic moiety size at the S2-site and (iv) a unique folding conformation assumed by the phenoxyacetyl moiety at the S4-site.   Goto Sponge  NotDistinct  Permalink
