Potent, selective, orally bioavailable inhibitors of tumor necrosis factor-alpha converting enzyme (TACE): Discovery of indole, benzofuran, imidazopyridine and pyrazolopyridine P1? substituents

Potent and selective inhibitors of tumor necrosis factor-alpha converting enzyme (TACE) were discovered with several new heterocyclic P1? groups in conjunction with cyclic beta-amino hydroxamic acid scaffolds. Among them, the pyrazolopyridine provided the best overall profile when combined with tetrahydropyran beta-amino hydroxamic acid scaffold. Specifically, inhibitor 49 showed IC50 value of 1 nM against porcine TACE and 170 nM in the suppression of LPS-induced TNF-alpha of human whole blood. Compound 49 also displayed excellent selectivity over a wide panel of MMPs as well as excellent oral bioavailability (F% > 90%) in rat n-in-1 PK studies.

Acyl-Directed ortho-Borylation of Anilines and C7 Borylation of Indoles using just BBr3

Indoles are privileged heterocycles found in many biologically active pharmaceuticals and natural products. However, the selective functionalization of the benzenoid moiety in indoles in preference to the more reactive pyrrolic unit is a significant challenge. Herein we report that N-acyl directing groups enable the C7-selective C?H borylation of indoles using just BBr3. This transformation shows some functional-group tolerance and notably proceeds with C6 substituted indoles. The directing group can be readily removed in situ and the products isolated as the pinacol boronate esters. Acyl-directed electrophilic borylation can be extended to carbazoles and anilines with excellent ortho selectivity. 4-amino-indoles are amenable to this process, with acyl group installation and directed electrophilic C?H borylation enabling selective formation of C5-BPin-indoles.

Synthesis of Diketohexenoic Acid Derivatives by Alkenylation of Indoles and Pyrroles with 4-Pyrones

A new synthesis of functionalized (Z)-6-hetaryl-2,4-dioxo-5-hexenoic acids based on acid-catalyzed alkenylation of indoles and pyrroles with derivatives of 5-substituted 4-pyrone-2-carboxylic acid in 37-82% yields has been developed. Coupling between isochelidonic acid and indoles followed by decarboxylation afforded biologically important (E)-6-indolyl-2,4-dioxo-5-hexenoic acids. These ring-opening reactions proceed with high regioselectivity through nucleophilic attack at the C-6 position of the pyrone ring. Reactions of ethyl 6-indolyl-2,4-dioxo-5-hexenoate with nucleophiles are useful for the production of different beta-(indolyl)vinyl-containing azaheterocycles.

Rearrangements of a Water Molecule in Both Directions between Two Hydrogen-Bonding Sites of 5-Hydroxyindole Cation: Experimental Determination of the Energy Threshold for the Rearrangement

Rearrangements of a water molecule in both directions between two hydrogen-bonding (H-bonding) sites of the 5-hydroxyindole (5HI) cation was investigated in the gas phase. IR-dip spectra of jet-cooled 5HI-(H2O)1 revealed that two structural isomers, 5HI(OH)-(H2O)1 and 5HI(NH)-(H2O)1, in which a water molecule is bound to either the OH group or the NH group of 5HI, were formed in the S0 state. The IR photodissociation spectrum of [5HI-(H2O)1]+ generated by two-color resonant two-photon ionization (2C-R2PI) via the S1-S0 origin of 5HI(NH)-(H2O)1 clearly showed that [5HI(OH)-(H2O)1]+ and [5HI(NH)-(H2O)1]+ coexist in the D0 state. The appearance of [5HI(OH)-(H2O)1]+ after R2PI via the S1-S0 origin of 5HI(NH)-(H2O)1 is explained by isomerization of [5HI(NH)-(H2O)1]+ to [5HI(OH)-(H2O)1]+, which corresponds to the rearrangement of the water. In addition, isomerization in the opposite direction was also observed when [5HI-(H2O)1]+ was generated via the S1-S0 origin of 5HI(OH)-(H2O)1. The upper limit of the energy threshold for the rearrangement of the water in [5HI(NH)-(H2O)1]+ was experimentally determined to be 2127 ¡À 30 cm-1 from the adiabatic ionization energy of 5HI(NH)-(H2O)1. Above the energy threshold, the water molecule in [5HI-(H2O)1]+ may fluctuate between the two preferential H-bonding sites of 5HI+.
