Disclosed herein are derivatives of tetracaine that, among other things, block cyclic nucleotide gated (CNG) channels and are useful in the treatment of diseases characterized by overactive CNG channels such as retinal degeneration diseases.

tetracaine derivatives with substituents on the aromatic ring was prepared and evaluated for block of retinal rod cyclic nucleotide-gated (CNG) channels. Aromatic substitutions had little effect starting with the basic tetracaine scaffold, but electron-withdrawing substituents significantly improved the blocking potency of an octyl-tail derivative of tetracaine. In particular, halogen substitutions at either
