The proton resonance spectra of tetrahydropyran, at room temperature and -85C where the ring inversion is slow on the NMR timescale, 2-methoxy-, 3-methyl- and several 4-substituted tetrahydropyrans, 2-methyl-1,3-dioxolane and the rigid cyclic ethers 7-oxabicyclo[2.2.1]heptane and 1,8-cineole heve been recorded and completely analysed. These results together with literature data on acyclic and cyclic ethers (1,3- and 1,4-dioxane, dioxolane, 4-oxa-5alpha-androstane etc.) have allowed the determination of the oxygen substituent chemical shifts (SCS) in these systems. This data set consisting of 78 proton chemical shifts in 17 compounds has been used to test the application of a previous theoritical model of proton chemical shifts to these compounds. It is shown that the model gives a very good account of the proton chemical shifts in these systems. The ether oxygen SCS are due to both steric and electrostatic terms, the steric term predominating at short distances (e.g. in the 1,3-diaxial interactions in methoxycyclohexanes). Conformational isomerism in these compounds has also been investigated. Low temperature NMR gave DeltaG (eq-ax) + 1.0 kcal mol-1 for 4 hydroxy-THP. Analysis of the couplings in the CHCH2OH side chain of 2-(hydroxymethyl)-THP has shown that the preferred conformer is gt in both chloroform and acetone solvents.

The intramolecular carbocyclization of difluorinated enol acetals has been achieved for the first time using gold(I) catalysis. Difluorinated enol acetals bearing a pendant alkene group can be cyclized and reduced in one pot to form fluorinated diol motifs. Alternatively, the cyclization of terminal alkynes allows for the synthesis of fluorinated pyran scaffolds. Both cyclization processes can be performed under mild conditions allowing access to complex products rich in functionality. The cyclic systems are synthesized concisely (maximum four steps) from trifluoroethanol, an inexpensive fluorinated feedstock.

Chemical optimization of the 5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (THPP) scaffold was conducted with a focus on cellular potency while maintaining high selectivity against PI3K isoforms. Compound 11f was identified as a potent, highly selective and orally available PI3Kdelta inhibitor. In addition, 11f exhibited efficacy in an in vivo antibody production model. The desirable drug-like properties and in vivo efficacy of 11f suggest its potential as a drug candidate for the treatment of autoimmune diseases and leukocyte malignancies.

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.

Aberrant activation of the MAPK pathway drives cell proliferation in multiple cancers. Inhibitors of BRAF and MEK kinases are approved for the treatment of BRAF mutant melanoma, but resistance frequently emerges, often mediated by increased signaling through ERK1/2. Here, we describe the fragment-based generation of ERK1/2 inhibitors that block catalytic phosphorylation of downstream substrates such as RSK but also modulate phosphorylation of ERK1/2 by MEK without directly inhibiting MEK. X-ray crystallographic and biophysical fragment screening followed by structure-guided optimization and growth from the hinge into a pocket proximal to the C-alpha helix afforded highly potent ERK1/2 inhibitors with excellent kinome selectivity. In BRAF mutant cells, the lead compound suppresses pRSK and pERK levels and inhibits proliferation at low nanomolar concentrations. The lead exhibits tumor regression upon oral dosing in BRAF mutant xenograft models, providing a promising basis for further optimization toward clinical pERK1/2 modulating ERK1/2 inhibitors.
