Potent and selective biphenyl azole inhibitors of adipocyte fatty acid binding protein (aFABP).

Herein we report the first disclosure of biphenyl azoles that are nanomolar binders of adipocyte fatty acid binding protein (aFABP or aP2) with up to thousand-fold selectivity against muscle fatty acid binding protein and epidermal fatty acid binding protein. In addition a new radio-ligand to determine binding against the three fatty acid binding proteins was also synthesized.

Structure of the complex of trypsin with a highly potent synthetic inhibitor at 0.97 A resolution.

The structure of the complex formed between bovine beta-trypsin and the highly potent synthetic inhibitor 2-{3'-[5'-methoxy-2'-(N-p-diaminomethylphenyl)amido]-1'-pyrido}-5-(N-2''-t-butylethanol)amidobenzoic acid (C(28)H(32)N(5)O(6)) has been determined at 0.97 A resolution. X-ray intensity data were collected to 0.
