Mosallanejad, Arash;Lorthioir, Olivier research published 《 Application of Tsunoda reagent to the convenient synthesis of drug-like pyrazoles》, the research content is summarized as follows. The versatility of the under-utilized (cyanomethylene)tributylphosphorane (CMBP, Tsunoda reagent) was demonstrated on two occasions in a drug discovery context. Firstly, the high reactivity of the phosphorane allowed the alkylation of a weakly acidic pyrazole when standard Mitsunobu conditions were unsuccessful. Secondly, the clean reaction profile generally obtained using CMBP allowed the direct use of the crude mixture in a subsequent Suzuki cross coupling. This reagent was utilized when isolation of the Mitsunobu reaction product (e.g. containing a boronate) was not desirable.

Here, we report the discovery of a new class of NPBWR1 antagonists identified from a fragment-based screen. Compound 1 (cAMP IC50 = 250μM; LE = 0.29) emerged as an initial hit. Further optimization of 1 by SAR-by-catalog and chem. modification produced 21a (cAMP IC50 = 30 nM; LE = 0.39) with a 6700-fold increase in potency from fragment 1. Somewhat surprisingly, Schild anal. of compound 21a suggested that in vitro inhibition of NPW-mediated effects on upon cAMP accumulation were saturable, and that compound 21a dose-dependently increased [125I]-hNPW23 dissociation rate constants from NPBWR1 in kinetic binding studies. Collectively, these data are inconsistent with a classic surmountable, orthosteric mechanism of inhibition. The benzimidazole inhibitors reported herein may therefore represent a mechanistically differentiated class of compounds with which to form a better appreciation of the pharmacol. and physiol. roles of this central neuropeptide system.

Historically, modulation of transforming growth factor β (TGF-β) signaling has been deemed a rational strategy to treat many disorders, though few successful examples have been reported to date. This difficulty could be partially attributed to the challenges of achieving good specificity over many closely related enzymes that are implicated in distinct phenotypes in organ development and in tissue homeostasis. Recently, fresolimumab and disitertide, two peptidic TGF-β blockers, demonstrated significant therapeutic effects toward human skin fibrosis. Therefore, the selective blockage of TGF-β signaling assures a viable treatment option for fibrotic skin disorders such as systemic sclerosis (SSc). In this report, we disclose selective TGF-β type II receptor (TGF-βRII) inhibitors that exhibited high functional selectivity in cell-based assays. The representative compound 29 attenuated collagen type I alpha 1 chain (COL1A1) expression in a mouse fibrosis model, which suggests that selective inhibition of TGF-βRII-dependent signaling could be a new treatment for fibrotic disorders.

Nanojars are a class of supramol. coordination complexes based on pyrazolate, Cu2+, and OH ions that self-assemble around highly hydrophilic anions and serve as efficient anion binding and extraction agents. The synthesis, characterization, and photophys. properties of pyrene-functionalized fluorescent nanojars are presented. Three pyrene derivatives, 4-(pyrene-1-yl)pyrazole (HL1), 4-(5-(pyrene-1-yl)pent-4-yn-1-yl)pyrazole (HL2), and 4-(3-(pyrazol-4-yl)propyl)-1-(pyrene-1-yl)-1,2,3-triazole (HL3), and the corresponding nanojars were synthesized and characterized using NMR spectroscopy and mass spectrometry. Electronic absorption, steady-state, and time-resolved fluorescence measurements were carried out to understand the interaction between the pyrene fluorophore and copper nanojars. Optical absorption measurements showed minor ground state interaction between the fluorophore and nanojars. The fluorescence of pyrene is significantly quenched when attached to nanojars, suggesting strong contribution from the paramagnetic Cu2+ ions. Significant static quenching is observed in the case of L1, when pyrene is directly bound to the nanojar, whereas in the case of L2 and L3, when pyrene is attached to the nanojars using flexible tethers, both static and dynamic quenching are observed

M.;Cano, Celine research published 《 Parallel Optimization of Potency and Pharmacokinetics Leading to the Discovery of a Pyrrole Carboxamide ERK5 Kinase Domain Inhibitor》, the research content is summarized as follows. The nonclassical extracellular signal-related kinase 5 (ERK5) mitogen-activated protein kinase pathway has been implicated in increased cellular proliferation, migration, survival, and angiogenesis; hence, ERK5 inhibition may be an attractive approach for cancer treatment. However, the development of selective ERK5 inhibitors has been challenging. Previously, we described the development of a pyrrole carboxamide high-throughput screening hit into a selective, submicromolar inhibitor of ERK5 kinase activity. Improvement in the ERK5 potency was necessary for the identification of a tool ERK5 inhibitor for target validation studies. Herein, we describe the optimization of this series to identify nanomolar pyrrole carboxamide inhibitors of ERK5 incorporating a basic center, which suffered from poor oral bioavailability. Parallel optimization of potency and in vitro pharmacokinetic parameters led to the identification of a nonbasic pyrazole analog with an optimal balance of ERK5 inhibition and oral exposure.

The successful application of immunotherapy in the treatment of cancer relies on effective engagement of immune cells in the tumor microenvironment. Phosphoinositide 3-kinase γ (PI3Kγ) is highly expressed in tumor-associated macrophages, and its expression levels are associated with tumor immunosuppression and growth. Selective inhibition of PI3Kγ offers a promising strategy in immuno-oncol., which has led to the development of numerous potent PI3Kγ inhibitors with variable selectivity profiles. To facilitate further investigation of the therapeutic potential of PI3Kγ inhibition, we required a potent and PI3Kγ-selective tool compound with sufficient metabolic stability for use in future in vivo studies. Herein, we describe some of our efforts to realize this goal through the systematic study of SARs within a series of 7-azaindole-based PI3Kγ inhibitors. The large volume of data generated from this study helped guide our subsequent lead optimization efforts and will inform further development of PI3Kγ-selective inhibitors for use in immunomodulation.
