Liu, Jiwen; Fu, Zice; Wang, Yingcai; Schmitt, Mike; Huang, Alan; Marshall, Derek; Tonn, George; Seitz, Lisa; Sullivan, Tim; Lucy Tang, H.; Collins, Tassie; Medina, Julio published the artcile< Discovery and optimization of CRTH2 and DP dual antagonists>, Name: 3-Chloro-4-methylbenzene-1-sulfonyl chloride, the main research area is phenylacetic acid derivative preparation prostanoid CRTH2 DP dual antagonist.

A series of phenylacetic acid derivatives was discovered as CRTH2 antagonists. Modification of the series led to compounds that are also antagonists of DP. Since activation of CRTH2 and DP are believed to play key roles in mediating responses of asthma and other immune diseases, this series was optimized to increase the dual antagonistic activities and improve pharmacokinetic properties. These efforts led to selection of AMG 009 as a clin. candidate.

Chang, Chia-Lin; Wu, Chin-Sheng; Wang, Sen-Wen; Wang, Jih-Pyang published the artcile< Synthesis and biological activity of 5-(2'-alkoxycarbonyl substituted phenoxy)furan-2-carboxylic acid derivatives>, SDS of cas: 22717-55-1, the main research area is alkoxycarbonylphenoxyfurancarboxylic acid derivative synthesis biol activity antiallergic antiinflammatory.

A series of 5-(2′-alkoxycarbonyl substituted phenoxy)furan-2-carboxylic acid derivatives were prepared by a facile synthetic route: reaction of Et 5-nitro-2-furoate with the corresponding salicylates. None of the compounds inhibited PMA-induced neutrophil superoxide formation. On the contrary, some carboxylates significantly inhibited fMLP-induced neutrophil degranulation with much greater activity than the pos. control, TFP. One compound also inhibited superoxide formation. Furthermore, another compound strongly inhibited β-glucuronidase and histamine release from mast cells. In particular, this compound was shown to be a novel lead compound with excellent anti-allergic and anti-inflammatory activities. The other compound was shown to be a novel lead compound with excellent anti-inflammatory activity.

The 1-benzyl-3,5-bis((E)-3-bromobenzylidene)piperidin-4-one displayed dual p300/EZH2 inhibition joined to cancer-selective cell death in a panel of tumor cells and in in-vivo xenograft models, a series of bis((E)-2-bromobenzylidene) cyclic compounds I (X = CH2) and I (X is NR, where R = H, Me, Bn, etc.) were prepared to test in biochem. (p300, PCAF, SIRT1/2, EZH2, and CARM1) and cellular (NB4, U937, MCF-7, SH-SY5Y) assays. The majority of I exhibited potent dual p300 and CARM1 inhibition, sometimes reaching the submicromolar level, and induction of apoptosis mainly in the tested leukemia cell lines. The most effective compounds in both enzyme and cellular assays carried a 4-piperidone moiety and a Me, benzyl, or acyl substituent at N1 position I [X is NR, where R = H, Me, Bn, 2-oxo-2-phenylethyl, 2-oxo-3-phenylpropyl, 2-oxo-4-phenylbutyl]. Elongation of the benzyl portion to I [X is NR, where R = 2-phenylethyl, 3-phenylpropyl] decreased the potency of compounds at both the enzymic and cellular levels, but the activity was promptly restored by introduction of a ketone group into the phenylalkyl substituent I [X is NR, where R = 2-oxo-2-phenylethyl, 3-oxo-3-phenylpropyl, 4-oxo-4-phenylbutyl]. Western blot analyses performed in NB4 and MCF-7 cells on selected compounds confirmed their inhibition of p300 and CARM1 through decrease of the levels of acetyl-H3 and acetyl-H4, marks for p300 inhibition, and of H3R17me2, mark for CARM1 inhibition.

Jiang, Yansong; Lu, Zijing; Wang, Pengcheng; Xu, Jianing; Wang, Li; Fan, Yong published the artcile< Immobilized dyes within anionic indium coordination polymer for photocatalytic 1O2 generation>, Product Details of Cl3H8InO4, the main research area is immobilized dye anionic indium coordination polymer photocatalytic singlet oxygen.

A new anionic indium coordination polymer, (Me2NH2)[In(OH-BDC)2]·H2O (1), has been designed and synthesized under solvothermal conditions based on organic ligand 5-hydroxyisophthalic acid. 1 exhibits a 2D layered structure with rhombic windows, which is stacked to form 3D supramol. network by the π-π stacking interactions of Ph rings of ligand in adjacent layers. It not only shows excellent resistance to acid or basic conditions but also has good tolerance to various common solvents. Moreover, due to the neg. charge of the host framework, it shows remarkable selective adsorption for pos. charge dyes such as methylene blue (MB), rhodamine B (RhB) and crystal violet (CV), and the removal rates are higher than 90%. In particular, the adsorption capability of 1 to RhB is higher than most CPs based adsorbents. In addition, MB@1 is a high-efficiency reactive oxygen species (ROS) producer with good photocatalytic activity for the oxidation of 1,5-dihydroxynaphthalene (1,5-DHN) and can be recycled five times without loss of activity. To our knowledge, it is the first time that dye@CP was used for ROS production and photooxidation of 1,5-DHN.

Demine, Stephane; Garcia Ribeiro, Rita; Thevenet, Julien; Marselli, Lorella; Marchetti, Piero; Pattou, Francois; Kerr-Conte, Julie; Devoogdt, Nick; Eizirik, Decio L. published the artcile< A nanobody-based nuclear imaging tracer targeting dipeptidyl peptidase 6 to determine the mass of human beta cell grafts in mice>, Related Products of 128-09-6, the main research area is beta cell DPP6 nanobody nuclear imaging; Human islet imaging; PET; Pancreatic beta cell imaging; Pancreatic beta cells; SPECT; Type 1 diabetes.

Type 1 diabetes is characterised by a progressive decline in beta cell mass. This is also observed following implantation of pancreatic islet allografts, but there is no reliable information regarding the time course of beta cell loss. This is due to the limited availability of non-invasive pancreatic islet imaging techniques. We have previously described that dipeptidyl peptidase 6 (DPP6) is an alpha and beta cell-specific biomarker, and developed a camelid antibody (nanobody ‘4hD29’) against it. We demonstrated the possibility to detect DPP6-expressing cells by single-photon emission computed tomog. (SPECT)/ computed tomog. (CT), but the correlation between the number of cells grafted and the SPECT signal was not assessed. Here, we investigate whether the 4hD29 nanobody allows us to detect different amounts of human pancreatic islets implanted into immune-deficient mice. In addition, we also describe the adaptation of the probe for use with positron emission tomog. (PET). DPP6 expression was assessed in human samples using tissue arrays and immunohistochem. The effect of the 4hD29 nanobody on cell death and glucose-stimulated insulin secretion was measured in EndoC-βH1 cells and in human islets using Hoechst/propidium iodide staining and an anti-insulin ELISA, resp. We performed in vivo SPECT imaging on severe combined immunodeficient (SCID) mice transplanted with different amounts of EndoC-βH1 cells (2 x 106, 5 x 106 and 10 x 106 cells), human islets (1000 and 3000) or pancreatic exocrine tissue using 99mTc-labeled 4hD29 nanobody. This DPP6 nanobody was also conjugated to N-chlorosuccinimide (NCS)-1,4,7-triazacyclononane-1,4,7-triacetic acid (NOTA), radiolabeled with either 67Ga (SPECT) or 68Ga (PET) and used in a proof-of-principle experiment to detect DPP6-expressing cells (Kelly neuroblastoma) grafted in SCID mice. The DPP6 protein is mainly expressed in pancreatic islets. Importantly, the anti-DPP6 nanobody 4hD29 allows non-invasive detection of high amounts of EndoC-βH1 cells or human islets grafted in immunodeficient mice. This suggests that the probe must be further improved to detect lower numbers of islet cells. The 4hD29 nanobody neither affected beta cell viability nor altered insulin secretion in EndoC-βH1 cells and human islets. The conversion of 4hD29 nanobody into a PET probe was successful and did not alter its specificity. These findings suggest that the anti-DPP6 4hD29 nanobody may become a useful tool for the quantification of human islet grafts in mice and, pending future development, islet mass in individuals with diabetes.
