Peptide agonists of the glucagon-like peptide-1 receptor (GLP-1R) have revolutionized diabetes therapy, but their use has been limited because they require injection. Herein, we describe the discovery of the orally bioavailable, small-mol., GLP-1R agonist PF-06882961 (danuglipron). A sensitized high-throughput screen was used to identify 5-fluoropyrimidine-based GLP-1R agonists that were optimized to promote endogenous GLP-1R signaling with nanomolar potency. Incorporation of a carboxylic acid moiety provided considerable GLP-1R potency gains with improved off-target pharmacol. and reduced metabolic clearance, ultimately resulting in the identification of danuglipron. Danuglipron increased insulin levels in primates but not rodents, which was explained by receptor mutagenesis studies and a cryogenic electron microscope structure that revealed a binding pocket requiring a primate-specific tryptophan 33 residue. Oral administration of danuglipron to healthy humans produced dose-proportional increases in systemic exposure (NCT03309241). This opens an opportunity for oral small-mol. therapies that target the well-validated GLP-1R for metabolic health.

C.;Willis, Anne E. research published 《 The pathogenesis of mesothelioma is driven by a dysregulated translatome》, the research content is summarized as follows. Malignant mesothelioma (MpM) is an aggressive, invariably fatal tumor that is causally linked with asbestos exposure. The disease primarily results from loss of tumor suppressor gene function and there are no druggable driver oncogenes associated with MpM. To identify opportunities for management of this disease we have carried out polysome profiling to define the MpM translatome. We show that in MpM there is a selective increase in the translation of mRNAs encoding proteins required for ribosome assembly and mitochondrial biogenesis. This in an enhanced rate of mRNA translation, abnormal mitochondrial morphol. and oxygen consumption, and a reprogramming of metabolic outputs. These alterations delimit the cellular capacity for protein biosynthesis, accelerate growth and drive disease progression. Importantly, we show that inhibition of mRNA translation, particularly through combined pharmacol. targeting of mTORC1 and 2, reverses these changes and inhibits malignant cell growth in vitro and in ex-vivo tumor tissue from patients with end-stage disease. Critically, we show that these pharmacol. interventions prolong survival in animal models of asbestos-induced mesothelioma, providing the basis for a targeted, viable therapeutic option for patients with this incurable disease.

The transcriptional repressor B-cell lymphoma 6 (BCL6) is frequently misregulated in diffuse large B-cell lymphoma (DLBCL) and has emerged as an attractive drug target for the treatments of lymphoma. In this article, a series of N-phenyl-4-pyrimidinamine derivatives were designed and synthesized as potent BCL6 inhibitors by optimizing hit compound N⁴-(3-chloro-4-methoxyphenyl)-N²-isobutyl-5-fluoro-2,4-pyrimidinediamine on the basis of the structure-activity relationship. Among them, compound I displayed the most potent activities, which significantly blocked the interaction of BCL6 with its corepressors, reactivated BCL6 target genes in a dose-dependent manner, and had better effects compared with the two pos. controls. Further studies indicated that a low dose of I could effectively inhibit germinal center formation. More importantly, I not only showed potent inhibition of DLBCL cell proliferation in vitro but also strongly suppressed the growth of DLBCL in vivo.

Han, Zhengyu;Liu, Gang;Wang, Rui;Dong, Xiu-Qin;Zhang, Xumu research published 《 Highly efficient Ir-catalyzed asymmetric hydrogenation of benzoxazinones and derivatives with a Bronsted acid cocatalyst》, the research content is summarized as follows. The Ir-catalyzed highly efficient asym. hydrogenation of benzoxazinones I (R = H, 7-CH₃, 6-Cl, etc.; R¹ = H, 4-OCH₃, 4-F, etc.) and derivatives II (R² = H, CH₃; R³ = C₆H₅, C₂H₅; n = 0, 1) was successfully developed with N-methylated ZhaoPhos as the ligand, which may display a new activation mode with a single anion-binding interaction among the substrate, cocatalyst Bronsted acid and ligand. This synthetic approach afforded a series of chiral dihydrobenzoxazinones III and derivatives IV with excellent results (>99% conversion, 88-96% yields, 91->99% ee, up to 40 500 TON). A key to success is the utilization of a strong Bronsted acid as the cocatalyst, such as hydrochloric acid, to form a possible single anion-binding interaction with the substrate and catalyst, which greatly contributed to the improvement of reactivity and enantioselectivity. Importantly, a creative and efficient synthetic route was developed to construct the important intermediate for the potential IgE/IgG receptor modulator through our catalytic methodol. system.

The BTK and JAK3 receptor tyrosine kinases are two validated and therapeutically amenable targets in the treatment of B-cell lymphomas. Here the authors report the identification of several classes of pyrimidine derivatives as potent BTK and JAK3 dual inhibitors. Among these mols., approx. two thirds displayed strong inhibitory capacity at less than 10 nM concentration, and four compounds could significantly inhibit the phosphorylation of BTK and JAK3 enzymes at concentrations lower than 1 nM. Addnl., these pyrimidine derivatives also exhibited enhanced activity to block the proliferation of B-cell lymphoma cells compared with the representative BTK inhibitor ibrutinib. In particular, two structure-specific compounds I and II displayed stronger activity than reference agents in cell-based evaluation, with IC₅₀ values lower than 10 μM. Further biol. studies, including flow cytometric anal., and a xenograft model for in vivo evaluation, also indicated their efficacy and low toxicity in the treatment of B-cell lymphoma. These findings provide a new insight for the development of novel anti-B-cell lymphoma drugs with multitarget actions.

Renal biopsy is currently the gold standard for diagnosing active renal vasculitis. In this pilot study, metabolomics anal. was used to investigate the differences in metabolic profiles between paired patients′ serum and urine samples collected during both the active and the remission phase of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV). Ten patients with AAV renal disease were included. Mean age was 61 years, with 6 patients each being male and Caucasian. Mean Birmingham Vasculitis Activity Score (BVAS) and mean glomerular filtration rate (GFR) were 17 and 28, resp. We found that while the citric acid cycle intermediates citrate, iso-citrate and oxaloacetate had lower intensities in the active phase samples as compared to the remission phase samples. The intensities of other metabolites of carbohydrate metabolism, amino acid metabolism, and nucleotide synthesis were significantly higher in the active phase samples, indicating the upregulation of these pathways for the production of energy and other biomols. such as proteins and nucleic acids during the active phase of AAV. This pilot study suggests that serum and urinary metabolomic profiling may be useful to monitor disease activity in renal AAV.

This material had been characterized by different techniques showing the presence of small and uniform Pd nanoparticles in about 2 nm size. Measuring contact angle confirmed important role of starch on increasing hydrophilic nature of the catalyst. Using 0.05 mol% of this catalyst aryl iodides or bromides reacted with boronic acids at room temperature in aqueous media and the corresponding products were obtained in very good to excellent yields. Hot filtration and PVPy poisoning tests confirmed the heterogeneous nature of the catalyst. E-factor of the catalyst was found in acceptable range and close to green chem. standards This catalyst was magnetically recovered and recycled for 10 consecutive times with small decrease in activity. Also, the robustness of this catalytic system was demonstrated by the characterization of the reused catalyst.
