Fragment based search for small molecule inhibitors of HIV-1 Tat-TAR
摘要:
Basic molecular building blocks such as benzene rings, amidines, guanidines, and amino groups have been combined in a systematic way to generate ligand candidates for HIV-1 TAR RNA. Ranking of the resulting compounds was achieved in a fluorimetric Tat-TAR competition assay. Although simple molecules such as phenylguanidine are inactive, few iteration steps led to a set of ligands with IC50 values ranging from 40 to 150 mu M. 1,7-Diaminoisoquinoline 17 and 2,4,6-triaminoquinazoline 22 have been further characterized by NMR titrations with TAR RNA. Compound 22 is bound to TAR at two high affinity sites and shows slow exchange between the free ligand and the RNA complex. These results encourage investigations of dimeric ligands built from two copies of compound 22 or related heterocycles. (C) 2014 Elsevier Ltd. All rights reserved.

Methods for identifying selective RNA-binding small molecules by NMR screening. The method provides a screening cascade to identify molecules that bind to an RNA structure, such as HIV TAR. Compounds that bind to structured RNAs and that are useful to disrupt the formation of RNA-protein complexes, such as P-TEFb-Tat-TAR complex.
