Synthesis and biological evaluation of rhodanine derivatives as PRL-3 inhibitors
摘要:
A series of rhodanine derivatives was synthesized and evaluated for their ability to inhibit PRL-3. Benzylidene rhodanine derivative showed good biological activity, while compound 5e was the most active in this series exhibiting IC50 value of 0.9 mu M in vitro and showed a reduced invasion in cell-based assay.

In an effort to generate novel translation initiation inhibitors for cancer therapy, a series of 2'-benzyloxy-5'-substituted-5-benzylidene-thiazolidine-2,4-thione and dione derivatives was synthesized and evaluated for activity in translation initiation specific assays. Several candidates of the 5-benzylidene-thiazolidine-2,4-diones (3c, 3d, and 3f) and -thiones (2b, 2e, and 2j), inhibit cell growth with low muM GI(50) mediated by inhibition of translation initiation, which involves partial depletion of intracellular Ca2+ stores and strong phosphorylation of eIF2alpha.
