  Thyroid hormone analogs. Synthesis of 3'-substituted 3,5-diiodo-L-thyronines and quantitative structure-activity studies of in vitro and in vivo thyromimetic activities in rat liver and heart

  摘要：

  Twenty-nine novel 3'-substituted derivatives of the thyroid hormone 3,3',5-triiodo-L-thyronine (T3) have been synthesized by using established methods and by a new route involving manipulation of a 3'-formyl intermediate. In vitro hormone receptor binding (to intact nuclei) and in vivo thyromimetic activity (induction of mitochondrial 3-phosphoglycerate oxidoreductase, GPDH) were measured in rat liver and heart for these new analogues and for the 18 previously reported 3'-substituted 3,5-diiodo-L-thyronines. Analysis of the binding data using theoretical conformational and quantitative structure-affinity methods implies that the 3'-substituent recognition site on the thyroid hormone receptor is hydrophobic and limited in depth to the length of the natural iodo substituent, but has sufficient width to accommodate a phenyl or cyclohexyl group. Receptor binding is reduced by approximately 10-fold in 3'-acyl derivatives which form strong intramolecular acceptor hydrogen bonds with the adjacent 4'-hydroxyl. The compounds studied showed no differences in their relative affinities for heart and liver nuclei, suggesting that receptors in these tissues are similar. However, the relationships between thyromimetic activity (induction of GPDH) and nuclear binding showed some tissue differences. A high correlation between activity and binding is observed for full agonists in the heart, but an equally significant correlation for the liver data is only seen when 3'-substituent bulk (molar refractivity) is included in the analysis. These results suggest the possibility that differential tissue penetration or access to receptors may occur in vivo.

  3'-arylmethyl T3 analogues show that electronegative groups at the para position increase both receptor binding and selectivity in vivo. However, increasing 3'-arylmethyl hydrophobicity increases receptor binding but reduces selectivity. Substitution at ortho and meta positions reduces both binding and selectivity. Replacement of the 3,5-iodo groups by halogen or methyl maintains selectivity, with 3

  3′-Heteroarylmethyl analogues (1)–(8) of the natural thyroid hormone 3,3′,5-tri-iodo-L-thyronine (T3) were synthesized as potential selective (cardiac-sparing) thyromimetics. The diphenyl ether moiety was constructed by condensation of 3-substituted 4-methoxyphenols with a 3,5-dinitro-L-tyrosine derivative. Synthesis of the key phenols (28)–(32) required the in situ preparation, at low temperatures
