Oh, Soo-Jin published the artcileMONNA, a potent and selective blocker for transmembrane protein with unknown function 16/anoctamin-1, Name: 1,3-Dibromonaphthalene, the publication is Molecular Pharmacology (2013), 84(5), 726-735, database is CAplus and MEDLINE.

Transmembrane protein with unknown function 16/anoctamin-1 (ANO1) is a protein widely expressed in mammalian tissues, and it has the properties of the classic calcium-activated chloride channel (CaCC). This protein has been implicated in numerous major physiol. functions. However, the lack of effective and selective blockers has hindered a detailed study of the physiol. functions of this channel. In this study, we have developed a potent and selective blocker for endogenous ANO1 in Xenopus laevis oocytes (xANO1) using a drug screening method we previously established. We have synthesized a number of anthranilic acid derivatives and have determined the correlation between biol. activity and the nature and position of substituents in these derived compounds A structure-activity relationship revealed novel chem. classes of xANO1 blockers. The derivatives contain a -NO₂ group on position 5 of a naphthyl group-substituted anthranilic acid, and they fully blocked xANO1 chloride currents with an IC₅₀ < 10 μM. The most potent blocker, N-((4-methoxy)-2-naphthyl)-5-nitroanthranilic acid (MONNA), had an IC₅₀ of 0.08 μM for xANO1. Selectivity tests revealed that other chloride channels such as bestrophin-1, chloride channel protein 2, and cystic fibrosis transmembrane conductance regulator were not appreciably blocked by 10∼30 μM MONNA. The potent and selective blockers for ANO1 identified here should permit pharmacol. dissection of ANO1/CaCC function and serve as potential candidates for drug therapy of related diseases such as hypertension, cystic fibrosis, bronchitis, asthma, and hyperalgesia.

He, Yali published the artcilePyrazol-1-yl-propanamides as SARD and Pan-Antagonists for the Treatment of Enzalutamide-Resistant Prostate Cancer, Related Products of bromides-buliding-blocks, the publication is Journal of Medicinal Chemistry (2020), 63(21), 12642-12665, database is CAplus and MEDLINE.

We report herein the design, synthesis, and pharmacol. characterization of a library of novel aryl pyrazol-1-yl-propanamides as selective androgen receptor degraders (SARDs) and pan-antagonists that exert broad-scope AR antagonism. Pharmacol. evaluation demonstrated that introducing a pyrazole moiety as the B-ring structural element in the common A-ring-linkage-B-ring nonsteroidal antiandrogens’ general pharmacophore allowed the development of a new scaffold of small mols. with unique SARD and pan-antagonist activities even compared to our recently published AF-1 binding SARDs such as UT-155 and UT-34. Novel B-ring pyrazoles exhibited potent AR antagonist activities, including promising distribution, metabolism, and pharmacokinetic properties, and broad-spectrum AR antagonist properties, including potent in vivo antitumor activity. I was able to induce an 80% tumor growth inhibition of xenografts derived from the enzalutamide-resistant (Enz-R) VCaP cell line. These results represent an advancement toward the development of novel AR antagonists for the treatment of Enz-R prostate cancer.

Williams, Sierra J. published the artcileOrthogonal bioluminescent probes from disubstituted luciferins, COA of Formula: C10H16Br3N, the publication is Biochemistry (2021), 60(8), 563-572, database is CAplus and MEDLINE.

Bioluminescence imaging with luciferase-luciferin pairs is routinely used to monitor cellular functions. Multiple targets can be visualized in tandem using luciferases that process unique substrates, but only a handful of such orthogonal probes are known. Multiplexed studies require addnl. robust, light-emitting mols. In this work, we report new luciferins for orthogonal imaging that comprise disubstituted cores. These probes were found to be bright emitters with various engineered luciferases. The unique patterns of light output also provided insight into enzyme-substrate interactions necessary for productive emission. Screening studies identified mutant luciferases that could preferentially process the disubstituted analogs, enabling orthogonal imaging with existing bioluminescent reporters. Further mutational analyses revealed the origins of substrate selectivity. Collectively, this work provides insights into luciferase-luciferin features relevant to bioluminescence and expands the number of probes for multicomponent tracking.

Parveen, Shagufta published the artcileSelective synthesis and comparative activity of olefinic isomers of 1,2-benzothiazine-1,1-dioxide carboxylates as aldose reductase inhibitors, Formula: C7H5Br2F, the publication is RSC Advances (2014), 4(40), 21134-21140, database is CAplus.

1,2-Benzothiazine-1,1-dioxides I (R¹ = 2,4,5-F₃, 4-Br-2-F; R² = CH₃) and II were selectively synthesized via the Wittig olefination reaction under various temperature conditions. At 40 °C, esters I with high Z-stereoselectivity (83-87%) were formed, while esters II formed preferentially with moderate to excellent regioselectivity at 100-120 °C (77-96%). The acid isomers I (R² = H) and II (R² = H), formed by acid hydrolysis of the corresponding esters, were found to inhibit aldose reductase in order of activity β,γ-unsaturated > Z-α,β-unsaturated > E-α,β-unsaturated isomers. The β,γ-unsaturated isomer II (R¹ = 4-Br-2F; R² = H) exhibited the most potent inhibition activity, with an IC₅₀ value of 0.057 μM. This was further supported by docking studies.

Berton, Mateo published the artcileOn-demand synthesis of organozinc halides under continuous flow conditions, Application of Ethylbromofluoroacetate, the publication is Nature Protocols (2018), 13(1), 324-334, database is CAplus and MEDLINE.

Organozinc reagents are versatile building blocks for introducing C(sp₂)-C(sp₃) and C(sp₃)-C(sp₃) bonds into organic structures. However, despite their ample synthetic versatility and broad functional group tolerance, the use of organozinc reagents in the laboratory is limited because of their instability, exothermicity and water sensitivity, as well as their labor-intensive preparation Herein, we describe an on-demand synthesis of these useful reagents under continuous flow conditions, overcoming these primary limitations and supporting widespread adoption of these reagents in synthetic organic chem. To exemplify this procedure, a solution of Et zincbromoacetate is prepared by flowing Et bromoacetate through a column containing metallic zinc. The temperature of the column is controlled by a heating jacket and a thermocouple in close contact with it. Advice on how to perform the procedure using alternative equipment is also given to allow a wider access to the methodol. Here we describe the preparation of 50 mL of solution, which takes 1 h 40 min, although up to 250-300 mL can be prepared with the same column setup at a rate of 30 mL per h. The procedure provides the reagent as a clean solution with reproducible concentration Organozinc solutions generated in flow can be coupled to a second flow reactor to perform a Reformatsky reaction or can be collected over a flask containing the required reagents for a batch Negishi reaction.

Gao, Yong-Chao published the artcileSulfite-Promoted C-H Fluoroalkyl Sulfuration of Imidazoheterocycles with Bromofluoroacetate and Elemental Sulfur, SDS of cas: 401-55-8, the publication is Synthesis (2020), 52(17), 2541-2550, database is CAplus.

A transition-metal-free sulfite-promoted three-component C-H sulfuration between imidazoheterocycles, elemental sulfur and bromofluoroacetate was developed. Sulfites, including Na₂S₂O₄, NaHSO₃ and Na₂S₂O₃, were able to promote the formation of two C-S bonds in one step using elemental sulfur as a green sulfurating agent, allowing the rapid introduction of the synthetically useful S-fluoroacetate group into imidazoheterocycles. These new imidazoheterocycle derivatives bearing an S-fluoroacetate group can be easily modified to produce pharmaceutically attractive compounds

Gong, Jun published the artcileCircularly polarized luminescent 4,4′-bicarbazole scaffold for facile construction of chiroptical probes, Safety of 1-Bromooctane, the publication is Dyes and Pigments (2022), 109969, database is CAplus.

Small mols. with circularly polarized luminescence (CPL) are especially valuable in solution-based applications, like chiroptical probes for effective sensing. Such application was not well explored due in part to hard introduction of appropriate triggerable fluorophores. An easily post-modifiable CPL-active scaffold (4) is reported, and a feasible strategy to construct chiroptical probes for sensing hypochlorous acid is further proposed. Helically chiral 4 with a 4,4′-bicarbazole scaffold exhibits a large Stokes shift ≤142 nm and g_lum value of 0.9 × 10^-3. Through facile construction of phenothiazine moiety on 4, red-emitting compound 5 was obtained in high yield (85.3%), showing distinct optical and chiroptical responses towards hypochlorous acid with good liner relations and CPL sign blue-shifting of 120 nm in vitro. The probe is also applied to detect endogenous hypochlorous acid in living macrophages and can serve as a CPL sensor. Taking 5 as an application example, the authors envision that CPL-enabling scaffold 4 could find broad use in the design of more chiroptical probes.

Percec, Virgil published the artcileSelf-organization of rectangular bipyramidal helical columns by supramolecular orientational memory epitaxially nucleated from a Frank-Kasper σ phase, Recommanded Product: 1-Bromododecane, the publication is Giant (2022), 100084, database is CAplus.

Programming living and soft complex matter via primary structure and self-organization represents the key methodol. employed to design functions in biol. and synthetic nanoscience. Memory effects have been used to create com. technologies including liquid crystal displays and biomedical applications based on shape memory polymers. Supramol. orientational memory (SOM), induced by an epitaxial nucleation mediated by the close contact spheres of cubic phases, emerged as a pathway to engineer complex nanoscale soft matter of helical columnar hexagonal arrays. SOM preserves the crystallog. directions of close contact supramol. spheres from the 3D phase upon cooling to the columnar hexagonal periodic array. Despite the diversity of 3D periodic and quasiperiodic nanoarrays of supramol. dendrimers, including Frank-Kasper and quasicrystal, all examples of SOM to date were mediated by Im3m (body-centered cubic, BCC) and Pm3n (Frank-Kasper A15) cubic phases. Expanding the scope of SOM to non-cubic arrays is expected to generate addnl. morphologies that were not yet available by any other methods. Here we demonstrate the SOM of a dendronized triphenylene that self-organizes into helical columnar hexagonal and tetragonal P4₂/mnm (Frank-Kasper σ) phases. Structural anal. of oriented fibers by X-ray diffraction reveals that helical columnar hexagonal domains self-organize an unusual rectangular bipyramidal morphol. upon cooling from the σ phase. The discovery of SOM in a non-cubic Frank-Kasper phase indicates that this methodol. may be expanded to other periodic and quasiperiodic nanoarrays organized from self-assembling dendrimers and, most probably, to other soft and living complex matter.
