Luteolin, 5,7-dihydroxy-2-(3,4-dihydroxyphenyl)-4H-chromen-4-one, has been proposed and proved to be a novel dopamine transporter (DAT) activator. In order to develop this potential of luteolin, a series of novel luteolin derivatives were designed, synthesized, and evaluated for their DAT agonistic activities, utilizing

C-terminal domain tissue inhibitor of metalloproteinases-3 (TIMP-3) mutations cause the rare hereditary blindness Sorsby's fundus dystrophy (SFD), which involves loss of retinal pigment epithelial (RPE) cells. Since wild-type TIMP-3 causes apoptosis, we investigated whether SFD TIMP-3 might kill RPE and
