[https://www.uniprot.org/uniprot/TTHY_HUMAN TTHY_HUMAN] Defects in TTR are the cause of amyloidosis transthyretin-related (AMYL-TTR) [MIM:[https://omim.org/entry/105210 105210]. A hereditary generalized amyloidosis due to transthyretin amyloid deposition. Protein fibrils can form in different tissues leading to amyloid polyneuropathies, amyloidotic cardiomyopathy, carpal tunnel syndrome, systemic senile amyloidosis. The disease includes leptomeningeal amyloidosis that is characterized by primary involvement of the central nervous system. Neuropathologic examination shows amyloid in the walls of leptomeningeal vessels, in pia arachnoid, and subpial deposits. Some patients also develop vitreous amyloid deposition that leads to visual impairment (oculoleptomeningeal amyloidosis). Clinical features include seizures, stroke-like episodes, dementia, psychomotor deterioration, variable amyloid deposition in the vitreous humor.<ref>PMID:11243784</ref> <ref>PMID:15735344</ref> <ref>PMID:19167329</ref> <ref>PMID:3818577</ref> <ref>PMID:3022108</ref> <ref>PMID:6651852</ref> <ref>PMID:6583672</ref> <ref>PMID:3135807</ref> <ref>PMID:1517749</ref> <ref>PMID:1932142</ref> <ref>PMID:7923855</ref> <ref>PMID:8382610</ref> <ref>PMID:8428915</ref> <ref>PMID:9733771</ref> <ref>PMID:12403615</ref> <ref>PMID:16185074</ref> <ref>PMID:16627944</ref> <ref>PMID:6487335</ref> <ref>PMID:3722385</ref> <ref>PMID:2891727</ref> <ref>PMID:2161654</ref> <ref>PMID:2363717</ref> <ref>PMID:1656975</ref> <ref>PMID:2046936</ref> <ref>PMID:1570831</ref> <ref>PMID:1734866</ref> <ref>PMID:1520326</ref> <ref>PMID:1520336</ref> <ref>PMID:1544214</ref> <ref>PMID:1351039</ref> <ref>PMID:1301926</ref> <ref>PMID:1362222</ref> <ref>PMID:1436517</ref> <ref>PMID:8352764</ref> <ref>PMID:8038017</ref> <ref>PMID:8257997</ref> <ref>PMID:8095302</ref> <ref>PMID:1997217</ref> <ref>PMID:8019560</ref> <ref>PMID:8081397</ref> <ref>PMID:7914929</ref> <ref>PMID:8133316</ref> <ref>PMID:7910950</ref> <ref>PMID:7655883</ref> <ref>PMID:7850982</ref> <ref>PMID:8579098</ref> <ref>PMID:9066351</ref> <ref>PMID:8990019</ref> <ref>PMID:9605286</ref> <ref>PMID:10036587</ref> <ref>PMID:10627135</ref> <ref>PMID:10694917</ref> <ref>PMID:10211412</ref> <ref>PMID:10439117</ref> <ref>PMID:10611950</ref> <ref>PMID:10071047</ref> <ref>PMID:10436378</ref> <ref>PMID:10842705</ref> <ref>PMID:10842718</ref> <ref>PMID:10882995</ref> <ref>PMID:11445644</ref> <ref>PMID:12557757</ref> <ref>PMID:11866053</ref> <ref>PMID:12050338</ref> <ref>PMID:12771253</ref> <ref>PMID:15214015</ref> <ref>PMID:15478468</ref> <ref>PMID:15217993</ref> <ref>PMID:17453626</ref> <ref>PMID:17577687</ref> <ref>PMID:17503405</ref> <ref>PMID:17635579</ref> Defects in TTR are a cause of hyperthyroxinemia dystransthyretinemic euthyroidal (HTDE) [MIM:[https://omim.org/entry/145680 145680].

Symptoms include burning pain and paresthesias involving the ventral surface of the hand and fingers which may radiate proximally. Impairment of sensation in the distribution of the median nerve and thenar muscle atrophy may occur.

Transthyretin amyloidosis is a fatal disorder caused by transthyretin amyloid aggregation. Stabilizing the native structure of transthyretin is an effective approach to inhibit amyloid aggregation. To develop kinetic stabilizers of transthyretin, it is crucial to explore compounds that selectively bind to transthyretin in plasma. Our recent findings demonstrated that the uricosuric agent benziodarone selectively binds to transthyretin in plasma. Here, we report the development of benziodarone analogues with enhanced potency for selective binding to transthyretin in plasma compared to benziodarone. These analogues featured substituents of chlorine, bromine, iodine, a methyl group, or a trifluoromethyl group, at the 4-position of the benzofuran ring. X-ray crystal structure analysis revealed that CH...O hydrogen bonds and a halogen bond are important for the binding of the compounds to the thyroxine-binding sites. The bioavailability of benziodarone analogues with 4-Br, 4-Cl, or 4-CH(3) was comparable to that of tafamidis, a current therapeutic agent for transthyretin amyloidosis.
