    • Docking studies were carried out employing the Schrödinger suite of programs. The X-ray crystal structure 1EZF was used as a glide receptor grid after protein preparation. The water forming a bridge to ASN 215 was included into the receptor grid. Ligands were optimized before docking via the ligprep routine. Docking was carried out in SP and XP mode with similar results. Figures were prepared with PyMol.;

    • The geometry of the isoxazole 1 was reasoned from the subsequent synthesis steps providing the 4,1-benzoxazepine scaffold. The regioisomeric 3-(dimethoxymethyl)-4-isopropyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl) -1,2-oxazole will not yield such a cyclization pruduct.

Subsequently, 100 μl solution was extracted with 200 μl chloroform, 200 μl methanol and 60 μl 5 N sodium hydroxide and adjusted to 2 mM squalene. An aliquot of the organic phase was mixed with scintillation fluid and measured for β-emission.
