Abstract:
Combined photochemical arylation, "nuisance effect" (SN Ar) reaction sequences have been employed in the design of small arrays for immediate deployment in medium-throughput X-ray protein-ligand structure determination. Reactions were deliberately allowed to run "out of control" in terms of selectivity; for example the ortho-arylation of 2-phenylpyridine gave five products resulting from mono- and bisarylations combined with SN Ar processes. As a result, a number of crystallographic hits against NUDT7, a key peroxisomal CoA ester hydrolase, have been identified.

Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...
