Zinc finger proteins, such as Zfp943, rely on the presence of zinc ions for their structural and functional integrity. The class of compounds that may indirectly inhibit Zfp943 does so primarily by chelating zinc ions or interfering with DNA binding and transcription factor activities. 1,10-phenanthroline and TPEN are examples of chelators that bind zinc, which could lead to the destabilization of zinc finger domains. Similarly, clioquinol and pyrithione zinc have affinities for metal ions and can disrupt the normal activity of metal-dependent enzymes and proteins. Disulfiram and PDTC are additional chelators that, beyond their primary uses, have the capacity to sequester zinc and thus may alter the function of zinc-dependent proteins.

Furthermore, compounds like dithizone and mithramycin A are known to interact with DNA in a manner that can obstruct the binding of transcription factors, which may include zinc finger proteins. Thioflavin T, while typically associated with staining amyloid structures, can also bind to nucleic acids and potentially disrupt protein-DNA interactions. 2-Mercaptopyridine N-oxide and phenylarsine oxide are chelators that may affect the activity of proteins dependent on metal ions such as zinc. Lastly, triptolide, though not a chelator, is a compound that affects numerous cellular signaling pathways, including those involving transcription factors, thus could influence the activity of a broad range of proteins including zinc finger proteins like Zfp943.
