The deposition of aggregates of human islet amyloid polypeptide (hIAPP) has been correlated with the death of β-cells in type II diabetes mellitus. The actual molecular mechanism of cell death remains largely unknown; however, it has been postulated that the process of aggregation from monomeric hIAPP is closely involved. A possible cause of cellular toxicity may be through the disruption of structural integrity of the cell membrane by IAPP. Herein, a water-soluble curcumin derivative, CurDAc, is used to investigate the mitigation of hIAPP aggregation in the absence and presence of lipid membrane.

A series of new 3-(glycinamido)-benzofuran-2-carboxamide and 3-(b-alanamido)-benzo furan-2-carboxamide derivatives (5a-o) were synthesized for the purpose of developing the new bioactive chemical entities and evaluated for their in vitro antimicrobial, anti-inflammatory and DPPH radical scavenging activities. The synthesized compounds were characterized by NMR, IR, Mass and X-ray crystallographic techniques. ª 2015 Production and hosting by Elsevier B.V. on behalf of King Saud University.

The new chemical entity, water‐soluble pyrazole curcumin derivative (PyCurOAc) was designed, synthesized and characterized for the purpose of inhibition of AGE formation. The compound showed an excellent in vitro AGEs inhibition activity than curcumin itself as well as the standard. Further, the AGE inhibition activity was substantiated in vivo using C.elegans as an animal model. The mechanistic investigation for the inhibition of AGEs with PyCurOAc was studied with glod‐4 expressions in C.elegans and glucose trapping method. This study suggests that the synthesized compound could be used to treat the formation of AGEs in hyperglycemic nematodes and higher animals.
