A series of NSD2-PWWP1 inhibitors I (R = 4-cyanophenyl, 4-cyanonaphthalen-1-yl, 8-cyanoquinolin-5-yl, etc.; R1 = H, OMe, F, Cl, CF3; R2 = H, Me, OMe; R3 = aminomethyl, CHO, 4-aminopiperidin-1-yl, etc.), and further structure-based optimization resulted in a potent inhibitor compound I (R = 4-cyanonaphthalen-1-yl; R1 = R2 = Me; R3 = 4-aminopiperidin-1-yl) (II), that has high selectivity toward the NSD2-PWWP1 domain were reported. The detailed biol. evaluation revealed that compound II can bind to NSD2-PWWP1 and then affect the expression of genes regulated by NSD2. The current discovery will provide a useful chem. probe to the future research in understanding the specific regulation mode of NSD2 by PWWP1 recognition and pave the way to develop potential drugs targeting NSD2 protein.

Perez, Lark J.; Ng, Wai-Leung; Marano, Paul; Brook, Karolina; Bassler, Bonnie L.; Semmelhack, Martin F. published the artcile< Role of the CAI-1 Fatty Acid Tail in the Vibrio cholerae Quorum Sensing Response>, Application of C5H10O3, the main research area is Vibrio quorum sensing CAI1 fatty acid tail preparation antibacterial.

Quorum sensing is a mechanism of chem. communication among bacteria that enables collective behaviors. In V. cholerae, the etiol. agent of the disease cholera, quorum sensing controls group behaviors including virulence factor production and biofilm formation. The major V. cholerae quorum-sensing system consists of the extracellular signal mol. called CAI-1 and its cognate membrane bound receptor called CqsS. Here, the ligand binding activity of CqsS is probed with structural analogs of the natural signal. Enabled by the discovery of a structurally simplified analog of CAI-1, a focused library was prepared and analyzed. The mols. were designed to probe the effects of conformational and structural changes along the length of the fatty acid tail of CAI-1. The results, combined with pharmacophore modeling, suggest a mol. basis for signal mol. recognition and receptor fidelity with respect to the fatty acid tail portion of CAI-1. These efforts provide novel probes to enhance discovery of anti-virulence agents for the treatment of V. cholerae.

Huang, Ruili; Southall, Noel; Cho, Ming-Hsuang; Xia, Menghang; Inglese, James; Austin, Christopher P. published the artcile< Characterization of Diversity in Toxicity Mechanism Using in Vitro Cytotoxicity Assays in Quantitative High Throughput Screening>, Category: esters-buliding-blocks, the main research area is compound toxicity mechanism screening caspase apoptosis viability cluster analysis.

Assessing the potential health risks of environmental chem. compounds is an expensive undertaking that has motivated the development of new alternatives to traditional in vivo toxicol. testing. One approach is to stage the evaluation, beginning with less expensive and higher throughput in vitro testing before progressing to more definitive trials. In vitro testing can be used to generate a hypothesis about a compound’s mechanism of action, which can then be used to design an appropriate in vivo experiment Here we begin to address the question of how to design such a battery of in vitro cell-based assays by combining data from two different types of assays, cell viability and caspase activation, with the aim of elucidating the mechanism of action. Because caspase activation is a transient event during apoptosis, it is not possible to design a single end-point assay protocol that would identify all instances of compound-induced caspase activation. Nevertheless, useful information about compound mechanism of action can be obtained from these assays in combination with cell viability data. Unsupervised clustering in combination with Dunn’s cluster validity index is a robust method for identifying mechanisms of action without requiring any a priori knowledge about mechanisms of toxicity. The performance of this clustering method is evaluated by comparing the clustering results against literature annotations of compound mechanisms.

Holm Hansen, Rikke; Højsgaard Chow, Helene; Christensen, Jeppe Romme; Sellebjerg, Finn; von Essen, Marina Rode published the artcile< Dimethyl fumarate therapy reduces memory T cells and the CNS migration potential in patients with multiple sclerosis.>, Reference of 112-63-0, the main research area is .

BACKGROUND: Dimethyl fumarate (DMF) is a disease-modifying therapy for patients with relapsing-remitting multiple sclerosis (RRMS). T cells are major contributors to the pathogenesis of RRMS, where they regulate the pathogenic immune response and participate in CNS lesion development. OBJECTIVES: In this study we evaluate the therapeutic effects of DMF on T cell subpopulations, their CNS migration potential and effector functions. METHODS: Blood and CSF from untreated and DMF-treated patients with RRMS and healthy donors were analyzed by flow cytometry. RESULTS: DMF reduced the prevalence of circulating proinflammatory CD4+ and CD8+ memory T cells, whereas regulatory T cells were unaffected. Furthermore, DMF reduced the frequency of CD4+ T cells expressing CNS-homing markers. In coherence, we found a reduced recruitment of CD4+ but not CD8+ T cells to CSF. We also found that monomethyl fumarate dampened T cell proliferation and reduced the frequency of TNF-α, IL-17 and IFN-γ producing T cells. CONCLUSION: DMF influences the balance between proinflammatory and regulatory T cells, presumably favoring a less proinflammatory environment. DMF also reduces the CNS migratory potential of CD4+ T cells whereas CD8+ T cells are less affected. Altogether, our study suggests an anti-inflammatory effect of DMF mainly on the CD4+ T cell compartment.

Wang, Xuewen; Cai, Changqing; Liang, Qichang; Xia, Meng; Lai, Lihua; Wu, Xia; Jiang, Xiaoyun; Cheng, Hao; Song, Yinjing; Zhou, Qiang published the artcile< Integrated transcriptomics and metabolomics analyses of stress-induced murine hair follicle growth inhibition>, Application of C19H34O2, the main research area is hair follicle growth inhibition psychol stress transcriptome metabolome; chronic restraint stress; hair growth inhibition; hexokinase-1; metabolomics; transcriptomics.

Psychol. stress plays an important role in hair loss, but the underlying mechanisms are not well-understood, and the effective therapies available to regrow hair are rare. In this study, we established a chronic restraint stress (CRS)-induced hair growth inhibition mouse model and performed a comprehensive anal. of metabolomics and transcriptomics. Metabolomics data anal. showed that the primary and secondary metabolic pathways, such as carbohydrate metabolism, amino acid metabolism, and lipid metabolism were significantly altered in skin tissue of CRS group. Transcriptomics anal. also showed significant changes of genes expression profiles involved in regulation of metabolic processes including arachidonic acid metabolism, glutathione metabolism, glycolysis gluconeogenesis, nicotinate and nicotinamide metabolism, purine metabolism, retinol metabolism and cholesterol metabolism Furthermore, RNA-Seq analyses also found that numerous genes associated with metabolism were significantly changed, such as Hk-1, in CRS-induced hair growth inhibition. Overall, our study supplied new insights into the hair growth inhibition induced by CRS from the perspective of integrated metabolomics and transcriptomics analyses.
