Published: March 2004

The synthesis and structure-activity relationships of N-phenyl-N'-[3-(4-phenylnaphthylidinoyl)]urea derivatives 3 as a novel structural class of potent ACAT inhibitors is described. A 3-methoxy group substituted on the naphthylidinone 4-phenyl ring, together with a 1-N-(n)butyl substitution, SM-32504 (3m), gave a potent ACAT inhibitor, in vitro, respectively. The most potent compound, SM-32504 (3m), decreased the serum cholesterol level significantly in a high fat and high cholesterol-fed mouse model.

Chemoprevention is one of the accessible strategies for preventing, delaying or reversing cancer processing utilizing chemical intervention of carcinogenesis. NAD(P)H quinone oxidoreductase 1 (NQO1) is a xenobiotic metabolizing cytosolic enzyme/protein with important functional properties towards oxidation stress, supporting its ability in detoxification/chemoprotective role. A set of 3,5-diylidene-4-piperidones (as curcumin mimics) bearing alkyl sulfonyl group were synthesized with potential NQO1 induction properties.

The modification of proteins and other biomolecules with the small protein ubiquitin has enthralled scientists from many disciplines for decades, creating a broad research field. Ubiquitin research is particularly rich in molecular and mechanistic understanding due to a plethora of (poly)ubiquitin structures alone and in complex with ubiquitin machineries. Furthermore, due to its favorable properties, ubiquitin serves as a model system for many biophysical and computational techniques.

Histone deacetylase 6 (HDAC6) is a promising target for treating neurodegenerative disorders, several cancer types and viral infections. Unique among HDACs, the HDAC6 isoform possesses a zinc finger ubiquitin-binding domain (UBD) crucial for managing misfolded protein aggregates and facilitating viral infection. HDAC6 binds aggregated polyubiquitinated proteins through its UBD, mediating their transport to the aggresome and subsequent removal via autophagy.

Dysregulation of choline phospholipid metabolism and overexpression of phosphatidylcholine-specific phospholipase C (PC-PLC) is implicated in various cancers. Current known enzyme inhibitors include compounds based on a 2-morpholino-5--benzylamino benzoic acid, or hydroxamic acid, scaffold. In this work, 81 compounds were made by modifying this core structure to explore the pharmacophore.

Alzheimer's disease is a neurodegenerative chronic disease with a severe social and economic impact in the societies, which still lacks an efficient therapy. Several pathophysiological events (β-amyloid [Aβ] deposits, τ-protein aggregation, loss of cholinergic activity, and oxidative stress) occurs in the progression of the disease. Therefore, the search for efficient multi-targeted agents for the treatment of Alzheimer's disease becomes indispensable.
