Design, synthesis and structure–activity relationship of indolylindazoles as potent and selective covalent inhibitors of interleukin-2 inducible T-cell kinase (ITK)

Interleukin-2 inducible T-cell kinase (ITK), a member of the Tec family of tyrosine kinases, plays an important role in T cell signaling downstream of the T-cell receptor (TCR). Herein we report the discovery of a series of indolylindazole based covalent ITK inhibitors with nanomolar inhibitory potency against ITK, good kinase selectivity and potent inhibition of the phosphorylation of PLCγ1 and ERK1/2 in living cells. A computational study provided insight into the interactions between inhibitors and Phe437 at the ATP binding pocket of ITK, suggesting that both edge-to-face π-π interaction and the dihedral torsion angle contribute to inhibitors’ potency. Compounds 43 and 55 stood out as selective covalent inhibitors with potent cellular activity, which could be used as chemical tools for further study of ITK functions.

Suzuki-type cross-coupling reaction of unprotected 3-iodoindazoles with pinacol vinyl boronate: An expeditive C-3 vinylation of indazoles under microwave irradiation

Herein we report an expeditive C-3 vinylation of unprotected 3-iodoindazoles under microwave irradiation. Ten C-5 substituted 3-vinylindazole derivatives, nine of them novel, were synthesized through this method, which proceeds in moderate to excellent yields starting from C-5 substituted 3-iodoindazole derivatives. In all cases, the C-3 vinylated derivative was the only isolated product. This methodology allows access to 3-vinylated indazoles selectively and directly without the need of N-protection. 3-Vinylindazoles could be interesting synthetic intermediates allowing access to biologically active molecules.

ML212: A small-molecule probe for investigating fluconazole resistance mechanisms in Candida albicans

The National Institutes of Health Molecular Libraries and Probe Production Centers Network (NIH-MLPCN) screened >300,000 compounds to evaluate their ability to restore fluconazole susceptibility in resistant Candida albicans isolates. Additional counter screens were incorporated to remove substances inherently toxic to either mammalian or fungal cells. A substituted indazole possessing the desired bioactivity profile was selected for further development, and initial investigation of structure-activity relationships led to the discovery of ML212.

Optimisation of ITK inhibitors through successive iterative design cycles

Based on a hit cluster of compounds inhibiting interleukin-2 inducible T-cell kinase (ITK) in the submicromolar range a series of ITK inhibitor libraries were synthesized. Through iterative design cycles including kinase crystal structure information, indolylindazole libraries were identified which showed low nanomolar activity in enzymatic and cellular assays. The potential of these novel lead series was confirmed through in vivo tests in an anti-CD3-IL2 mouse model. The intravenous administration of highly potent ITK inhibitor 11o resulted in dose-dependent, efficient suppression of IL-2.

Rapid preparation of triazolyl substituted NH-heterocyclic kinase inhibitors via one-pot Sonogashira coupling-TMS-deprotection-CuAAC sequence

The one-pot, three-component Sonogashira coupling-TMS-deprotection-CuAAC ("click") sequence is the key reaction for the rapid synthesis of triazolyl substituted N-Boc protected NH-heterocycles, such as indole, indazole, 4-, 5-, 6-, and 7-azaindoles, 4,7-diazaindole, 7-deazapurines, pyrrole, pyrazole, and imidazole. Subsequently, the protective group was readily removed to give the corresponding triazolyl derivatives of these tremendously important NH-heterocycles. All compounds have been tested in a broad panel of kinase assays. Several compounds, 8f, 8h, 8k, and 8l, have been shown to inhibit the kinase PDK1, a target with high oncology relevance, and thus they are promising lead structures for the development of more active derivatives. The X-ray structure analysis of compound 8f in complex with PDK1 has revealed the detailed binding mode of the molecule in the kinase. The Royal Society of Chemistry 2011.
