The invention relates to compounds of formula (I) and related aspects.

##STR00001##

An organic light emitting element produced by using a light emitting composition that contains both a first compound having a PBHT value more than 0.730 and a second compound having ES1 lower than that of the first compound and AEsT less than 0.20 eV is excellent in durability. ES1 is the lowest excited singlet energy level, AEsT is the difference between the lowest excited singlet energy level and the lowest excited triplet energy level.

The present disclosure relates to compounds, pharmaceutical compositions comprising such compounds, and use of such compounds in methods of treatment or in medicaments for treatment of inflammatory diseases and certain neurological disorders that are related to inflammatory signaling processes, including but not limited to misfolded proteins.

The present invention provides compounds of formula (I):

##STR00001##

which are useful in the control of endoparasites, for example heartworms, in warm-blooded animals.
