A series of new 4-arylidene curcumin analogues (4-arylidene-1,7-bisarylhepta-1,6-diene-3,5-diones) were synthesized and found to be potent antiproliferative agents against a panel of cancer cell lines at submicromolar to low micromolar concentrations by SRB assay. Their inhibitory abilities against NF-κB was evaluated by High Content Analysis (HCA) based immunofluorescence assay; and the Akt signalling inhibition was determined by fluorescence polarization assay and western blot respectively. The Structure-Activity Relationship was discussed. Our results revealed that 4-arylidene curcumin analogues may work in a multi-targets manner in cancer cell.

This study focuses on the misfolding and aggregation of α-Syn as a central mechanism linking various pathological processes in PD. Maintaining α-Syn proteostasis through suitable inhibitors emerges as an effective approach to prevent PD. A more efficient strategy for PD treatment involves disintegrating neurotoxic oligomers and fibrils into normal functional α-Syn using inhibitors.

Hck, a Src family nonreceptor tyrosine kinase (SFK), has recently been established as an attractive pharmacological target to improve pulmonary function in COVID-19 patients. Hck inhibitors are also well known for their regulatory role in various malignancies and autoimmune diseases. Curcumin has been previously identified as an excellent DYRK-2 inhibitor, but curcumin's fate is tainted by its instability in the cellular environment.

The proteasomal 19S regulatory particle (RP) associated deubiquitinases (DUBs) have attracted much attention owing to their potential as a therapeutic target for cancer therapy. Identification of new entities against 19S RP associated DUBs and illustration of the underlying mechanisms is crucial for discovery of novel proteasome blockers. In this study, a series of 4-arylidene curcumin analogues were identified as potent proteasome inhibitor by preferentially blocking deubiquitinase function of proteasomal 19S RP with moderate 20S CP inhibition.

Curcumin (diferuloylmethane) is a polyphenol natural product of the plant Curcuma longa, and has a diversity of antitumor activities. However, the clinical application of curcumin remains limited due to its poor pharmacokinetic characteristics. It is therefore critical to develop structural analogues of curcumin with increasing anticancer activity.

Synthesis of random copolyester bearing 4-arylidene curcumin M 1 in the polymer backbone was prepared by solution polycondensation method. The influence of copolyester bearing 4-arylidene curcumin M 1 unit on the properties of copolyester such as inherent viscosity, solubility, and thermal stability was investigated and studied in detail. The inherent viscosity and polydispersity index of the copolyester were found to be 0.
