General description

1,5-Naphthalenedisulfonic acid tetrahydrate reacts with [n-Bu2SnO]n in a 1:1 stoichiometry followed by reaction with 2,2′-bipyridine-N,N′-dioxide (BPDO-I) to yield 1D-coordination polymer, [n-Bu2Sn(BPDO-I)(1,5-C10H6(SO3)2)]n.

Application



  • Assessment of verapamil in a myotonic dystrophy model: Research demonstrated verapamil′s efficacy in mitigating chloride and calcium channel dysfunctions in a myotonic dystrophy mouse model, suggesting its potential in treating related muscular dystrophies (Cisco et al., 2024).


  • Cardiac tissue modeling with verapamil: Verapamil hydrochloride was tested using human-induced pluripotent stem cell-derived cardiac tissues to evaluate drug interactions and cardiac responses, proving essential for advancing cardiac safety pharmacology (Miyagawa et al., 2024).
