Objective: Enteroendocrine cells (EECs) survey the gut luminal environment and coordinate hormonal, immune and neuronal responses to it. They exhibit well-characterised physiological roles ranging from the control of local gut function to whole body metabolism, but little is known regarding the regulatory networks controlling their differentiation, especially in the human gut. The small molecule isoxazole-9 (ISX-9) has been shown to stimulate neuronal and pancreatic beta-cell differentiation, both closely related to EEC differentiation. Our aim was to use ISX-9 as a tool to explore EEC differentiation. Methods: We investigated the effects of ISX-9 on EEC differentiation in mouse and human intestinal organoids, using real-time quantitative polymerase chain reaction (RT-qPCR), fluorescent-activated cell sorting, immunostaining and single-cell RNA sequencing. Results: ISX-9 increased the number of neurogenin3-RFP (Ngn3)-positive endocrine progenitor cells and upregulated NeuroD1 and Pax4, transcription factors that play roles in mouse EEC specification. Single-cell analysis showed induction of Pax4 expression in a developmentally late Ngn3+ population of cells and potentiation of genes associated with progenitors biased toward serotonin-producing enterochromaffin (EC) cells. Further, we observed enrichment of organoids with functional EC cells that was partly dependent on stimulation of calcium signalling in a population of cells residing outside the crypt base. Inducible Pax4 overexpression, in ileal organoids, uncovered its importance as a component of early human endocrine specification and highlighted the potential existence of two major endocrine lineages, the early appearing enterochromaffin lineage and the later developing peptidergic lineage which contains classical gut hormone cell types. Conclusion: Our data provide proof-of-concept for the controlled manipulation of specific endocrine lineages with small molecules, whilst also shedding new light on human EEC differentiation and its similarity to the mouse. Given their diverse roles, understanding endocrine lineage plasticity and its control could have multiple therapeutic implications.

A new series of 4-((4,4-dimethyl-2,6-dioxocyclohexylidene)methylamino)-N-(substituted)benzenesulfonamide 3?17, monosubstituted 2-((4-((4-aminophenyl)sulfonyl)phenyl)amino)methylene 18, and its disubstituted derivative 19 were synthesized from the starting material 2-((dimethylamino)methylene)-5,5-dimethylcyclohexane-1,3-dione 2. The crystal structures of compounds 2, 7 and 13 were reported by us through X-ray crystallography. All the prepared compounds were evaluated for their antibacterial activity against Gram-positive bacteria (Staphylococcus aureus, Bacillus subtilis, Clostridium sporogenes), Gram-negative bacteria (Pseudomonas aeruginosa, Escherichia coli), and antifungal activity against Aspergillus fumigatus, Penicillium chrysogenum, Fusarium oxysporum, Candida albicans. The synthesized compounds displayed interesting antimicrobial activity. Compounds 4 and 12 were the most potent in this study and displayed higher activity compared to the reference drugs, with MIC value of 3.9?31.3 mug/mL against a panel of Gram-positive, Gram-negative bacteria and fungi. Molecular modeling was performed inside the active site of dihydropteroate synthase. The synthesized compounds showed similar orientation and binding interactions to that of the co-crystallized ligand inside the binding pocket.

Gold-catalyzed bicyclic annulations of 4-methoxy-1,2-dienyl-5-ynes with isoxazoles afford indolizine derivatives with a structural rearrangement. The mechanism of these new annulations does not involve alpha-imino gold carbenes generated from gold pi-alkyne intermediates. We postulate alkyne attack on gold pi-allenes, yielding vinyl gold carbenes. These newly generated carbenes react with isoxazole derivatives to yield Z-3-imino-2-en-1-als, further enabling sequential cyclizations to deliver indolizine derivatives in two distinct classes.

Research on GABA receptors has a long history in Australia dating from 1958 with David Curtis and his colleagues in Canberra. This review traces many of the advances made in Australia guided by highly cited publications and some obscure ones. It covers the discovery of key chemicals with which to investigate GABA receptor function including bicuculline, muscimol, phaclofen, THIP and (+)-CAMP. Also described are findings relevant to the involvement of mutant GABA receptors in inherited epilepsy. The modulation of GABA receptors by a bewildering range of chemicals, especially by flavonoids and terpenoids, is discussed.

62348-13-4, Name is Isoxazole-5-carbonyl chloride, belongs to isoxazole compound, is a common compound. Safety of Isoxazole-5-carbonyl chlorideIn an article, once mentioned the new application about 62348-13-4.

The study described here concerns the synthesis of a series of thirty new symmetrically substituted imidothiocarbamate and imidoselenocarbamate derivatives and their evaluation for antitumoral activity in vitro against a panel of five human tumor cell lines: breast adenocarcinoma (MCF-7), colon carcinoma (HT-29), lymphocytic leukemia (K-562), hepatocarcinoma (Hep-G2), prostate cancer (PC-3) and one non-malignant mammary gland-derived cell line (MCF-10A). The GI50 values for eighteen of the compounds were below 10 muM in at least one cell line. Two cancer cells (MCF-7 and HT-29) proved to be the most sensitive to five compounds (1b, 2b, 3b, 4b and 5b), with growth inhibition in the nanomolar range, and compounds 1b, 3b, 7b, 8b and 9b gave values of less than 1 muM. In addition, all of the aforementioned compounds exhibited lower GI50 values than some of the standard chemotherapeutic drugs used as references. The results also reveal that the nature of the aliphatic chain (methyl is better than benzyl) at the selenium position and the nature of the heteroatom (Se better than S) have a marked influence on the antiproliferative activity of the compounds. These findings reinforce our earlier hypothesis concerning the determinant role of the selenomethyl group as a scaffold for the biological activity of this type of compound. Considering both the cytotoxic parameters and the selectivity index (which was compared in MCF-7 and MCF-10A cells), compounds 2b and 8b (with a selenomethyl moiety) displayed the best profiles, with GI50 values ranging from 0.34 nM to 6.07 muM in the five cell lines tested. Therefore, compounds 2b and 8b were evaluated by flow cytometric analysis for their effects on cell cycle distribution and apoptosis in MCF-7 cells. 2b was the most active, with an apoptogenic effect similar to camptothecin, which was used as a positive control. Both of them provoked cell cycle arrest leading to the accumulation of cells in either G2/M and S phase. These two compounds can therefore be considered as the most promising candidates for the development of novel generations of antitumor agents.

Several pyridine derivatives containing a biologically active benzenesulfonamide moiety (3-17) were synthesized from the strategic starting material 2-acetylpyridine (1). The structures of the newly synthesized compounds were elucidated on the basis of elemental analysis, IR,1H-NMR13C-NMR and mass spectral data. All the prepared compounds were evaluated for their in vitro anticancer activity against breast cancer cell lines (MCF-7). Most of the synthesized compounds showed good to moderate activity, especially compounds 11, 8, 13, 6, 14, 15 and 9 with IC50 values (23.9, 25.1, 26.6, 28.1, 29.9, 30.4 and 31.4 muM, respectively) which exhibited higher activity than the reference drug doxorubicin with IC50 value (47.9 muM) as positive control. Compounds 10 and 7 are nearly as active as doxorubicin as positive control, while compounds 5, 12, 17, 3 and 4 showed moderate activity. Compounds 18 and 19 exhibited no activity.
