of thiosemicarbazone analogs based on the benzophenone, thiophene, pyridine, and fluorene molecular frameworks has been prepared by chemical synthesis and evaluated as small-molecule inhibitors of the cysteine proteases cathepsin L and cathepsinB. The two most potent inhibitors of cathepsin L in this series (IC50 <135 nM) are brominated-benzophenone thiosemicarbazone analogs that are further functionalized
