Development of Benziodarone Analogues with Enhanced Potency for Selective Binding to Transthyretin in Human Plasma. J Med Chem 2024; 67:6987-7005. [PMID: 38670538 PMCID: PMC11089511 DOI: 10.1021/acs.jmedchem.3c02286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 03/31/2024] [Accepted: 04/01/2024] [Indexed: 04/28/2024]
Abstract
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-CH3 was comparable to that of tafamidis, a current therapeutic agent for transthyretin amyloidosis.

Abstract
Transthyretin amyloid cardiomyopathy and Transthyretin amyloid peripheral neuropathy are progressive disease conditions caused by Transthyretin amyloidosis (ATTR) fibril infiltration in the tissue. Transthyretin (TTR) protein misfolding and amyloid fibril deposits are pathological biomarkers of ATTR-related disorders. There are various treatment strategies targeting different stages in pathophysiology. One such strategy is TTR tetramer stabilization. Recently, a new TTR tetramer stabilizer, tafamidis, has been introduced that reduces the protein misfolding and amyloidosis and, consequently, disease progression in ATTR cardiomyopathy and peripheral neuropathy. This review will provide a comprehensive overview of the literature on tafamidis discovery, development, synthetic methods, pharmacokinetics, analytical methods and clinical trials. Overall, 7 synthetic methods, 5 analytical methods and 23 clinical trials have been summarized from the literature.

Abstract
Present study describes a high-performance liquid chromatography method for the determination of the potent kinetic stabilizer-Tafamidis in human plasma. It was approved for medical use in European Union in 2011. Ultra violet (UV) detection mode and isocratic elution of the mobile phase were set and made the analytical procedure fast and widely applicable. Chromatographic determination was performed on a Purospher® RP-18 column. The mobile phase consisted of 0.1% trifluoroacetic acid in water and acetonitrile in the ratio 42:58 v/v and the flow rate was 1.0 ml/min. All analyses were carried at a room temperature and the detector was set at 280 nm. Calibration curve over a range of 1.00-10.00 μM was constructed for the purposes of linearity method validation. The specificity and effectiveness of the developed method made it suitable for observation of patients' plasma Tafamidis concentration with time and drug therapy monitoring.

Abstract
Transthyretin (TTR) transports the retinol-binding protein-vitamin A complex and is a minor transporter of thyroxine in blood. Its tetrameric structure undergoes rate-limiting dissociation and monomer misfolding, enabling TTR to aggregate or to become amyloidogenic. Mutations in the TTR gene generally destabilize the tetramer and/or accelerate tetramer dissociation, promoting amyloidogenesis. TTR-related amyloidoses are rare, fatal, protein-misfolding disorders, characterized by formation of soluble aggregates of variable structure and tissue deposition of amyloid. The TTR amyloidoses present with a spectrum of manifestations, encompassing progressive neuropathy and/or cardiomyopathy. Until recently, the only accepted treatment to halt progression of hereditary TTR amyloidosis was liver transplantation, which replaces the hepatic source of mutant TTR with the less amyloidogenic wild-type TTR. Tafamidis meglumine is a rationally designed, non-NSAID benzoxazole derivative that binds with high affinity and selectivity to TTR and kinetically stabilizes the tetramer, slowing monomer formation, misfolding, and amyloidogenesis. Tafamidis is the first pharmacotherapy approved to slow the progression of peripheral neurologic impairment in TTR familial amyloid polyneuropathy. Here we describe the mechanism of action of tafamidis and review the clinical data, demonstrating that tafamidis treatment slows neurologic deterioration and preserves nutritional status, as well as quality of life in patients with early-stage Val30Met amyloidosis.
