Even though acylhydrazones are important structural motifs in medicinal chemistry, their further progression in development may be hampered by major instability and toxicity issues under physiological conditions. It is therefore of paramount importance to identify stable replacements for acylhydrazone linkers. Here, we present the first report on the design and synthesis of stable bioisosteres of acylhydrazone-based inhibitors of the aspartic protease endothiapepsin as a follow-up to a DCC study. The most successful bioisostere is equipotent, bears an amide linker and we confirmed its binding mode by X-ray crystallography. Having some validated bioisosteres of acylhydrazones readily available might accelerate hit-to-lead optimization for future acylhydrazone-based DCC projects.
