RESUMO
Novel heterocyclic thyromimetics are presented carrying carboxy-substituted benzofurans or sulfur containing heterocycles, as replacements for the amino acid side chain of T3. Potent agonists were identified in both series. SAR trends are examined and found to be mostly consistent with previously published thyromimetics. The lack of isoform selectivity demonstrated with isoform-selective transient THR transfection assays has been confirmed by corresponding in vivo studies.

Novel heterocycle-fused thyromimetics are presented carrying indoles or indazoles instead of the phenolic group in T3. Potent agonists were identified in both series. SAR trends are examined and found to be mostly consistent with previously published thyromimetics. Moderate THRbeta selectivity (approx. 10-fold) was observed in the indole series using isoform-selective transient THR transfection assays.
