INHIBITORS OF CYSTATHIONINE BETA SYNTHASE TO REDUCE THE NEUROTOXIC OVERPRODUCTION OF ENDOGENOUS HYDROGEN SULFIDE

The invention is directed to inhibitors of cystathionine beta synthase which, among other biochemical effects, allow reduction of the neurotoxic overproduction of endogenous hydrogen sulphide. These compounds and pharmaceutical compositions containing them are useful for the prevention and treatment of cognitive disorders such as cognitive disorders in Down syndrome. The invention also relates to methods for preventing or treating cognitive disorders including cognitive disorders in Down Syndrome.

A new family of bis-DCM based dopants for red OLEDs

We have synthesized a series of novel bis-DCM derivatives as candidate red dopants for use in organic light-emitting devices (OLEDs), by introducing various donor-substituted aryl rings. Compared to DCJTB (621 nm), the novel dopants (637-677 nm) showed more red-shifted emission in 1,2-dichloroethane. Using bis-DCMNEtOBu (7) as a dopant, we fabricated OLEDs with the configuration of ITO/4,4′,4″-tris(3-methylphenylammo)triphenylamine (m-MTDATA) (20 nm)/N,N′-bis(1-naphthyl)-diphenyl-1,1′-biphenyl-4,4′-diamine (NPB) (40 nm)/tris(8-quinolinolato)aluminium (Alq3) : red dopant (35 nm, x wt%)/Alq3 (35 nm) LiF/Al. The device with a doping concentration of 1.25 wt% showed pure red emission at λmax = 654 nm (chromaticity coordinate: x = 0.67, y = 0.33) and a maximum brightness of 2500 cd m-2. The chromaticity coordinates were almost independent of current density. Moreover, highly efficient red emission (x = 0.63, y = 0.36) was obtained in the 0.74 wt% doped device. The maximum external quantum efficiency was 4.46% at 7 V, the current efficiency was 3.43 cd A-1, and the power efficiency was 1.64 Im W-1. The highest brightness of 8300 cd m-2 was obtained at 19.6 V. The Royal Society of Chemistry 2005.
