A dual Bcl-X_L / Bcl-2 inhibitor was discovered from DNA-encoded libraries using a two steps process. In the first step, DNA was used to pair PNA-encoded fragments exploring > 250 000 combinations. In the second step, a focused library combining the selected fragments with linkers of different lengths and geometries led to the identification of tight binding adducts that were further investigated for their selective target engagement in pull-down assays, for their affinity by SPR, and their selectivity in a cytotoxicity assay. The best compound showed comparable cellular activity to venetoclax, the first-in-class therapeutic targeting Bcl-2.

Cundy, Nicholas J.;Hare, Roseanna K.;Tang, Tina;Leach, Andrew G.;Jowitt, Thomas A.;Qureshi, Omar;Gordon, John;Barnes, Nicholas M.;Brady, Catherine A.;Raven, Emma L.;Grainger, Richard S.;Butterworth, Sam research published 《 Design, synthesis and evaluation of tryptophan analogues as tool compounds to study IDO1 activity》, the research content is summarized as follows. The metabolism of L-tryptophan to N-formyl-L-kynurenine by indoleamine-2,3-dioxygenase 1 (IDO1) is thought to play a critical role in tumor-mediated immune suppression. While there has been significant progress in elucidating the overall enzymic mechanism of IDO1 and related enzymes, key aspects of the catalytic cycle remain poorly understood. Here we report the design, synthesis and biol. evaluation of a series of tryptophan analogs which have the potential to intercept putative intermediates in the metabolism of 1 by IDO1. Functionally-relevant binding to IDO1 was demonstrated through enzymic inhibition, however no IDO1-mediated metabolism of these compounds was observed Subsequent T_m-shift anal. shows the most active compound, 17, exhibits a distinct profile from known competitive IDO1 inhibitors, with docking studies supporting the hypothesis that 17 may bind at the recently-discovered S_i site. These findings provide a start-point for development of further mechanistic probes and more potent tryptophan-based IDO1 inhibitors.

Ciska, Ewa;Honke, Joanna;Drabinska, Natalia research published 《 Changes in glucosinolates and their breakdown products during the fermentation of cabbage and prolonged storage of sauerkraut: Focus on sauerkraut juice》, the research content is summarized as follows. Sauerkraut juice has not gained much scientific attention to date. Therefore, this study aimed to track changes in glucosinolates (GLS) during fermentation of white cabbage and the formation of corresponding breakdown products in sauerkraut and sauerkraut juice sep. and to evaluate their stability during prolonged storage of the final products. The results obtained indicate that both sauerkraut and sauerkraut juice are a good source of bioactive compounds: ascorbigen and isothiocyanates. The stability of individual compounds during storage varied, and the absolute content of phytochems. depended on the content of native GLS in the raw material and its bacterial composition The dominant compound was ascorbigen, stable in acidic pH in both sauerkraut and sauerkraut juice, even after prolonged storage. Sauerkraut juice was also found as a rich source of bioactive isothiocyanates. One 250 mL glass of sauerkraut juice (after two weeks) can deliver approx. 75μmol of bioactive ascorbien and isothiocyanates, hence it can be considered as functional food, delivering beneficial health effects.

Cho, Hye Jin;Kim, Kyung-su;Kim, Hyunwoo;Kim, Taewoo;Malyutin, Andrey G.;Rees, Douglas C.;Yoo, Byung-Kuk;Song, Changsik research published 《 Microcrystal Electron Diffraction Elucidates Water-Specific Polymorphism-Induced Emission Enhancement of Bis-arylacylhydrazone》, the research content is summarized as follows. Aggregation-induced emission (AIE) phenomena have gained intense interest over the last decades because of its importance in solid-state emission. However, the elucidation of a working mechanism is difficult owing to the limited characterization methods on solid-state mols., further complicated if dynamic structural changes occur. Here, a series of bis-arylacylhydrazones (BAHs) were synthesized, for which their AIE properties are only turned on by the reversible adsorption of water mols. We used microcrystal electron diffraction (MicroED) to determine the mol. structures of two BAHs directly from bulk powders (without attempting to grow crystals) prepared in the absence or presence of water adsorption. This study reveals the unambiguous characterization of the dependence of crystal packing on the specific cocrystn. with hydrates. The structural anal. demonstrates that water mols. form strong hydrogen bonds with three neighboring BAH-1, resulting in the almost complete planarization and restriction of the intramol. rotation of the mol. MicroED plays an important role in providing a decisive clue for the reversible polymorphism changes induced by the adsorption of water mols., regulating emissive properties.

Fatty acid amide hydrolase (FAAH) exerts its main function in the catabolism of the endogenous chem. messenger anandamide (AEA), thus modulating the endocannabinoid (eCB) pathway. Inhibition of FAAH may serve as an effective strategy to relieve anxiety and possibly other central nervous system (CNS)-related disorders. Positron emission tomog. (PET) would facilitate us to better understand the relationship between FAAH in certain disease conditions, and accelerate clin. translation of FAAH inhibitors by providing in vivo quant. information. So far, most PET tracers show irreversible binding patterns with FAAH, which would result in complicated quant. processes. Herein, we have identified a new FAAH inhibitor (1-((1-methyl-1H-indol-2-yl)methyl)piperidin-4-yl)(oxazol-2-yl)methanone (8) which inhibits the hydrolysis of AEA in the brain with high potency (IC₅₀ value 11 nM at a substrate concentration of 0.5μM), and without showing time-dependency. The PET tracer [¹¹C]8 (also called [¹¹C]FAAH-1906) was successfully radiolabeled with [¹¹C]MeI in 17 ± 6% decay-corrected radiochem. yield (n = 7) with >74.0 GBq/μmol (2 Ci/μmol) molar activity and >99% radiochem. purity. Ex vivo biodistribution and blocking studies of [¹¹C]8 in normal mice were also conducted, indicating good brain penetration, high brain target selectivity, and modest to excellent target selectivity in peripheral tissues. Thus, [¹¹C]8 is a potentially useful PET ligand with enzyme inhibitory and target binding properties consistent with a reversible mode of action.

This protocol was advantageous as it does not require prior preparation of arylidenemalononitrile or arylidene-1H-indene-1,3(2H)-dione substrates, due to the independent participation of the base in the two reactions. This mild, operationally multicomponent process could be employed for the transformation of a wide variety of com. available aldehydes into the corresponding indeno[1,2-b]oxepines I [R = H, 4-CNC₆H₄, 2-OMeC₆H₄, etc.; R¹ = Me, Et] or cyclopropyl acrylate core II in moderate to excellent yields under mild conditions.
