Synthesis and evaluation of haloperidol ester prodrugs metabolically activated by human carboxylesterase
Two types of haloperidol prodrugs in which a chemical modification was carried out on the hydroxyl group or carbonyl group were synthesized, and their metabolic activation abilities were evaluated in a human liver microsome (HLM) solution, a human small i
Synthesis and binding profile of haloperidol-based bivalent ligands targeting dopamine D2-like receptors
Homodimers of dopamine D2-like receptors are suggested to be of particular importance in the pathophysiology of schizophrenia and, thus, serve as promising targets for the discovery of atypical antipsychotics. This study describes the development of a series of novel bivalent molecules with a pharmacophore derived from the dopamine receptor antagonist haloperidol. These dimers were investigated in comparison to their monomeric analogues for their D2long, D2short, D3, and D4 receptor binding and the ability to bridge two neighboring receptor protomers. Radioligand binding studies provided diagnostic insights when Hill slopes close to two for the bivalent ligand 13 incorporating 22 spacer atoms and a comparative analysis with monovalent control ligands indicated a bivalent binding mode with a simultaneous occupancy of two neighboring binding sites.

PROTEASE-BINDING COMPOUNDS AND METHODS OF USE
Non-peptide, protease-binding compounds are described as useful in the detection, labelling, and inhibition of retroviral proteases. Aryl piperidinyl derivatives and other compounds related in structure have been found to be HIV-1 and HIV-2 protease-binding compounds.
