luminescent cyclometalated platinum(II) complexes functionalized with various substituted styryl groups on the cyclometallating ligand [Pt(C/N-ppy-4-styryl-R)(O/O-(O)CCR'CHCR'C(O))] (ppy-4-styryl-R = E-4(4-(R)styryl-2-phenylpyridine) (3, R' = Me (acac); 4, R' = (t)Bu (dpm); R = H, OMe, NEt2, NO2) have been prepared. All complexes undergo an E-Z photoisomerization process in CH2Cl2 solution under sunlight, as

This manuscript reports the synthesis and photophysical investigation of a series of IrIII complexes Ir(C∧N)2(O∧O) which are functionalized in the para position of the pyridine ring by styryl groups substituted with electron-donor and -acceptor end groups. The saturated derivative Ir(C∧N-ppy-4-CH2CH2C6H4OMe)2(O∧O-acac) (4a-H2) was formed from [Ir(C∧N-ppy-4-CH=CHC6H4OMe)2]2(μ-Cl)2 (3a) at 140 °C, whereas

studies showed that Comp-43 reduces mHTT levels by targeting GPR52 and promotes survival of mouse primary striatal neurons. Moreover, in vivo study showed that Comp-43 not only reduces mHTT levels but also rescues HD-related phenotypes in HdhQ140 mice. Taken together, our study confirms that inhibition of GPR52 is a promising strategy for HD therapy, and the GPR52antagonist Comp-43 might serve as a lead
