Property- and Structure-Guided Discovery of a Tetrahydroindazole Series of Interleukin-2 Inducible T-Cell Kinase Inhibitors
摘要:
Interleukin-2 inducible T-cell kinase (ITK), a member of the Tec family of tyrosine kinases, plays a major role in T-cell signaling downstream of the T-cell receptor (TCR), and considerable efforts have been directed toward discovery of ITK-selective inhibitors as potential treatments of inflammatory disorders such as asthma. Using a previously disclosed indazole series of inhibitors as a starting point, and using X-ray crystallography and solubility forecast index (SFI) as guides, we evolved a series of tetrahydroindazole inhibitors with improved potency, selectivity, and pharmaceutical properties. Highlights include identification of a selectivity pocket above the ligand plane, and identification of appropriate lipophilic substituents to occupy this space. This effort culminated in identification of a potent and selective ITK inhibitor (GNE-9822) with good ADME properties in preclinical species.

Recent studies revealed that norcarane (bicyclo[4.1.0]heptane) is oxidized to 2-norcarene (bicyclo[4.1.0]-hept-2-ene) and 3-norcarene (bicyclo[4.1.0]hept-3-ene) by iron-containing enzymes and that secondary oxidation products from the norcarenes complicate mechanistic probe studies employing norcarane as the substrate (Newcomb, M.; Chandrasena, R.

Diazomethane ring expansion of tricyclo[4.1.0.01,3]heptan-4-one provides a convenient route to three carbon-bridged spiropentanes. The relative rates of reaction and the migratory preferences of cyclopropyl vs methylene were examined for several cyclopropyl alkyl ketones, and were correlated with the results of HF/6-31G∗ MO calculations.

Three structurally analogous radical clock substrates with a 100-fold span in their rearrangement rates are hydroxylated by the diiron oxygenase AlkB to afford similar amounts of rearranged and unrearranged products. Such a result is predicted by a mechanistic scheme by which radical rebound competes with cage escape of the geminate substrate radical. The results show that radical clocks can measure both the radical life-time and the kinetics of cage escape.
