Probing 2H-Indazoles as Templates for SGK1, Tie2, and SRC Kinase Inhibitors

The broader and systematic application of a novel scaffold is often hampered by the unavailability of a short and reliable synthetic access. We investigated a new strategy for the design and synthesis of an array of N2-substituted aza-2H-indazole derivatives as potential kinase inhibitors. Guided by a rational ligand alignment approach to qualify the so-far underrepresented aza-2H-indazole scaffold, indazoles were connected at the N2 position with a phenyl spacer and an arylsulfonamide or amide linkage. Initial profiling against a panel of 30 kinases confirmed the in silico predicted selectivity bias. A synthesized focused library of 52 different aza-2H-indazole derivatives showed good initial selective inhibition against SGK1, Tie2, and SRC kinases, with the best representatives having IC50 values in the range of 500 nm. In a comparative computational study, these data were analyzed and rationalized in light of docking studies.

Selective cleavage of the N-propargyl group from sulfonamides and amides under ruthenium catalysis

The selective cleavage of the N-propargyl group from sulfonamides and amides under ruthenium catalysis is described. The reaction tolerates a broad range of functional groups, and the desired products were obtained in 10–95% yield.

BRD4-KINASE INHIBITORS AS CANCER THERAPEUTICS

METHODS OF INHIBITING BACTERIAL VIRULENCE AND COMPOUNDS RELATING THERETO

The present invention relates to compounds and methods for the treatment of bacterial infections. Because their mechanism of action does not involve killing of bacteria or inhibiting their growth, the potential for these compounds to induce drug resistance in bacteria is minimized. Through inhibiting bacterial virulence, the present invention provides a novel means of treating bacterial infections.

Potent Pan-Raf and Receptor Tyrosine Kinase Inhibitors Based on a Cyclopropyl Formamide Fragment Overcome Resistance

While selective BRafV600E inhibitors have been proven effective clinically, acquired resistance rapidly develops through reactivation of the mitogen-activated protein kinase (MAPK) pathway. Simultaneous targeting of multiple nodes in the pathway offers the prospect of enhanced efficacy as well as reduced potential for acquired resistance. Replacement pyridine group of Y-1 by a cyclopropyl formamide group afforded I-01 as a novel multitargeted kinase inhibitor template. I-01 displayed enzyme potency against Pan-Raf and receptor tyrosine kinases (RTKs). Based on the binding mode of I-01, analogues I-02-I-18 were designed and synthesized. The most promising compound I-16 potently inhibits all subtypes of Rafs with IC50 values of 3.49 (BRafV600E), 8.86 (ARaf), 5.78 (BRafWT), and 1.65 nM (CRaf), respectively. I-16 not only exhibit comparable antiproliferative activities with positive control compounds against HepG2, SW579, MV4-11, and COLO205 cell lines, but also suppress the proliferation of melanoma SK-MEL-2 harboring overexpressed BRafWT with IC50 values of 0.93 μM. The Western blot results for the ERK inhibition in human melanoma SK-MEL-2 cell lines show that I-16 inhibits the proliferation of SK-MEL-2 cell lines without paradoxical activation of ERK, which support the hypothesis that the inhibition of Pan-Raf and RTKs might be a tractable strategy to overcome the resistance of melanoma induced by the therapy with the current selective BRafV600E inhibitors.

Solvent hydrogen bonding and structural effects on nucleophilic aromatic substitution reactions. Part-2: Reaction of benzenesulphonyl chloride with anilines in propan-2-ol/2-methylpropan-2-ol mixtures

Substitution reactions of fourteen para- and meta-substituted anilines with benzenesulphonyl chloride in different mole fractions of propan-2-ol in 2-methylpropan-2-ol have been investigated conductometrically. The second order rate constants correlates satisfactorily with pKa values of the anilines and also with the Hammett's substituent constant. The para-substituted anilines shows a satisfactory correlation with Charton's LDR equation. The results of these correlations indicate the formation of an electron deficient transition state. The rate data correlate satisfactorily with macroscopic solvent parameters such as relative permittivity, εr and polarity, ETN. Multiple correlation analysis of the rate data via Kamlet-Taft's solvatochromic parameters reveals that the solvent dipolarityfpolarizability plays a dominant role in governing the reactivity.

Solvent hydrogen bonding and structural effects on nucleophilic substitution reactions: Part 3. Reaction of benzenesulfonyl chloride with anilines in benzene/ propan-2-ol mixtures

Substitution reactions of 13 para- and meta-substituted anilines with benzene-sulfonyl chloride in varying mole fractions of benzene in propan-2-ol have been investigated conductometrically, The second-order rate constants correlate well with pKa values of anilines and with the Hammett's equation. The negative Hammett reaction constant indicates the formation of an electron-deficient transition state. The rate data correlate satisfactorily with macroscopic solvent parameters such as relative permittivity, εr, and polarity, ETN. Correlation of rate data with Kamlet-Taft solvatochromic parameters (α, β, π*) suggests that both the specific and nonspecific solute-solvent interactions influence the reactivity.
