A series of 5-benzylidenerhodanine-3-acetamides bearing morpholino-, 4-arylpiperazinyl-, or 4-benzylpiperidinyl-moieties were synthesized and their inhibitory activities against acetylcholinesterase (AChE) were evaluated. Alteration of amide part and substitution on the benzylidene moiety resulted in change of anti-AChE activity. The most active compound was the 1-benzylpiperidinyl derivative containing 4-(dimethylamino) benzylidene scaffold. Notably, the intermediate compounds, namely 5-arylidene-rhodanine-3-acetic acids (3), showed mild inhibitory activity against 15-lipoxygenase (15-LOX), while the final compound 4 showed no activity against 15-LOX.

A photoelectric conversion device using a semiconductor fine material such as a semiconductor fine particle sensitized with a dye carried thereon, characterized in that the dye is a methine type dye having a specific partial structure, for example, a methine type dye having a specific carboxyl-substituted hetero ring on one side of a methine group and an aromatic residue substituted with a dialkylamino group or an organic metal complex residue on the other side of the methine group, or a methine type dye having a carboxyl-substituted aromatic ring on one side of a methine group and a heteroaromatic ring having a dialkylamino group or an organic metal complex residue on the otherside of the methine group; and a solar cell using the photoelectric conversion element. The photoelectric conversion element exhibits a conversion efficiency comparable or superior to that of a conventionally known photoelectric conversion element sensitized with a methine type dye.
