Metal-dependent protein phosphatases (PPMs) have essential roles in a variety of cellular processes, including inflammation, proliferation, differentiation, and stress responses, which are intensively investigated in cancer and metabolic diseases. Targeting PPMs to modulate host immunity in response to pathogens is an ambitious proposition. The feasibility of such a strategy is unproven because development of inhibitors against PPMs is challenging and suffers from poor selectivity. Combining a biomimetic modularization strategy with function-oriented synthesis, we design, synthesize and screen more than 500 pseudo-natural products, resulting in the discovery of a potent, selective, and non-cytotoxic small mol. inhibitor for PPM1A, SMIP-30. Inhibition of PPM1A with SMIP-30 or its genetic ablation (ΔPPM1A) activated autophagy through a mechanism dependent on phosphorylation of p62-SQSTM1, which restricted the intracellular survival of Mycobacterium tuberculosis in macrophages and in the lungs of infected mice. SMIP-30 provides proof of concept that PPMs are druggable and promising targets for the development of host-directed therapies against tuberculosis.

The colorimetric sensing label is a simple, cost-effective, and user-friendly tool for monitoring ammonia vapor (NH3) concentrations in food packaging. Numerous natural dyes present excellent NH3-sensitivity, but their low solubility in water limits their food-related applications. Herein, a special cellulose-based ink system with an EtOH/water mixture as solvent was proposed to improve the dispersion of non-aqueous dyes (curcumin and its analogs (indexed as Bur and Bur-BF2)). Subsequently, three sensing labels containing different dyes were prepared by simple screen-printing after optimizing the inks′ rheol. properties. Benefiting from the different intramol. charge-transfer (ICT) behaviors of dyes, each sensing label exhibited various characteristics in terms of the optical property, NH3-sensitivity, and fluorescent color-changing routes upon exposure to 0-50 ppm NH3. Importantly, all sensing labels showed excellent stability in environments with various relative humidity and temperature Therefore, three sensing labels were used to construct a multicolor fluorescent sensor array, which aimed to visually monitor the freshness of shrimp for consumers.

A series of novel ASK1 inhibitors, e.g., I and II with 1H-indazole scaffold were designed, synthesized and evaluated for their ASK1 kinase activity and AP1-HEK293 cell inhibitory effect. Systematic structure-activity relationship (SAR) efforts led to the discovery of promising compound II, which showed excellent in vitro ASK1 kinase activity and potent inhibitory effects on ASK1 in AP1-HEK293 cells. In a tumor necrosis factor-α (TNF-α)-induced HT-29 intestinal epithelial cell model, compound II exhibited a significantly protective effect on cell viability comparable to that of GS-4997; moreover, compound II exhibited no obvious cytotoxicity against HT-29 cells at concentrations up to 25μM. Mechanistic research demonstrated that compound II suppressed phosphorylation in the ASK1-p38/JNK signaling pathway in HT-29 cells and regulated the expression levels of apoptosis-related proteins. Altogether, these results showed that compound II may serve as a potential candidate compound for the treatment of inflammatory bowel disease (IBD).

The effect of Epichloe endophyte on phyllosphere microbes and leaf metabolites in Achnatherum inebrians was written by Liu, Bowen;Ju, Yawen;Xia, Chao;Zhong, Rui;Christensen, Michael J.;Zhang, Xingxu;Nan, Zhibiao. And the article was included in iScience in 2022.Synthetic Route of C19H16O4 The following contents are mentioned in the article:

Upon exposure to the prevailing environment, leaves become increasingly colonized by fungi and bacteria located on the surface (epiphytic) or within (endophytic) the leaves. Many cool season grasses, including Achnatherum inebrians, host a seed-borne, intercellular, mutualistic Epichloe fungal endophyte, the growth of which is synchronized with the host grass. A study utilizing illumina sequencing was used to examine the epiphytic and endophytic microbial communities in Epichloe endophyte-infected and endophyte-free A. inebrians plants growing under hot dry field conditions. The presence of Epichloe endophyte increased the Shannon and decreased Simpson diversity of bacterial and fungal communities. Sphingomonas and Hymenobacter bacteria and Filobasidium and Mycosphaerella fungi were growing largely epiphytically, whereas Methylobacterium, Escherichia-Shigella, and the fungus Blumeria were mostly found within leaves with the location of colonization influenced by the Epichloe endophyte. In addition, leaf metabolites in Epichloe-infected and Epichloe-free leaves were examined using LC/MS. Epichloe was significantly correlated with 132 metabolites.

Structure-Reactivity Relationships on Substrates and Inhibitors of the Lysine Deacylase Sirtuin 2 from Schistosoma mansoni (SmSirt2) was written by Monaldi, Daria;Rotili, Dante;Lancelot, Julien;Marek, Martin;Woessner, Nathalie;Lucidi, Alessia;Tomaselli, Daniela;Ramos-Morales, Elizabeth;Romier, Christophe;Pierce, Raymond J.;Mai, Antonello;Jung, Manfred. And the article was included in Journal of Medicinal Chemistry in 2019.Computed Properties of C13H12O2 The following contents are mentioned in the article:

The only drug currently available for treatment of the neglected disease Schistosomiasis is Praziquantel, and the possible emergence of resistance makes research on novel therapeutic agents necessary and urgent. To this end, the targeting of Schistosoma mansoni epigenetic enzymes, which regulate the parasitic life cycle, emerged as a promising approach. Due to the strong effects of human sirtuin inhibitors on parasite survival and reproduction, Schistosoma sirtuins were postulated as potential therapeutic targets. In vitro testing of synthetic substrates of S. mansoni sirtuin 2 (SmSirt2) and kinetic experiments on a myristoylated peptide demonstrated lysine long-chain deacylation as an intrinsic SmSirt2 activity in addition to its known deacetylase activity for the first time. Focused in vitro screening of the GSK Kinetobox library and structure-activity relationships of identified hits led to the first SmSirt2 inhibitors with activity in the low micromolar range. Several SmSirt2 inhibitors showed potency against both larval schistosomes (viability) and adult worms (pairing, egg laying) in culture without general toxicity to human cancer cells.

Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Computed Properties of C13H12O2

Effects of storage temperature on bisdemethoxycurcumin formation in fresh-cut yam (Dioscorea opposita) was written by Guo, Shuang;Ma, Yue;Wang, Yubin;Zhao, Wenting;Zheng, Yanyan;Wang, Pan;Wang, Dan;Zhao, Xiaoyan. And the article was included in Journal of Food Composition and Analysis in 2021.Recommanded Product: 33171-05-0 The following contents are mentioned in the article:

This study investigated the formation of bisdemethoxycurcumin in fresh-cut yam. The effects of storage temperature on the metabolites, expressions of critical genes, and activities of enzymes involved in the bisdemethoxycurcumin pathway in fresh-cut yam were studied by HPLC, qRT-PCR and com. kits. Storage at 25°C increased the contents of bisdemethoxycurcumin and its main intermediates compared to 4°C. It also greatly improved the activities of key enzymes in the phenylpropanoid pathway, including phenylalanine ammonia lyase (PAL), cinnamic acid-4-hydroxylase (C4H), and 4-coumarate-CoA ligase (4CL), and enhanced the gene expressions of PAL, C4H, 4CL, hydroxycinnamoyltransferase, and O-methyltransferase. These changes decreased the content of phenylalanine and increased the contents of p-coumaric acid, cinnamic acid, p-coumaroyl-CoA, and feruloyl-CoA. Importantly, storage at 25°C enhanced the expression of curcumin synthase, whereas it had no effect on diketide-CoA synthase, curcumin synthase 1, curcumin synthase 2, and curcumin synthase 3, in agreement with the observed increase in bisdemethoxycurcumin content in fresh-cut yam compared to 4°C.

Light scattering and NMR studies of Triton X-100 micelles in the presence of short chain alcohols and ethoxylates was written by Dharaiya, Nilesh;Bahadur, Prashant;Singh, Kulbir;Marangoni, D. Gerrard;Bahadur, Pratap.

Micellar characteristics of nonionic surfactant p-tert-octyl-phenoxy polyethylene (9.5) ether (Triton X-100) in aqueous media containing short-chain alcs. and their ethoxylates C_nE_m (n = 2, 4, 6 and m = 0, 1, 2) were examined by dynamic light scattering (DLS) and NMR (NMR). The micelle size increased with the addition of C₆E_m and decreased when C₂E_m alcs. were added to Triton X-100 solution; the increase and decrease in the micellar size in the presence of varying amounts of C₄E_m alcs. depends on the number of polar ethoxylate groups. The results are supported by viscosity and cloud point data and explained on the basis of solvophobic interaction. The interaction and location of additives in micelles is examined by ¹H and NOESY NMR. The studies indicate that C₂E_m mols. mostly remain in bulk water; C₆E_m mols. get solubilized toward the core of the aggregates, while C₄E_m mols. are localized in the shell region of micelle according to their octanol/water partition coefficient values.

A supramolecular complex of hydrazide-pillar[5]arene and bisdemethoxycurcumin with potential anti-cancer activity was written by Guo, Fang;Xia, Tao;Xiao, Ping;Wang, Qingyue;Deng, Zhitong;Zhang, Wang;Diao, Guowang. And the article was included in Bioorganic Chemistry in 2021.Formula: C19H16O4 The following contents are mentioned in the article:

Pillar[5]arene complexes of the naturally occurring compound bisdemethoxycurcumin (BDMC) were acquired for improving the water solubility and stability of BDMC. As a family member of curcuminoid compounds, BDMC has many interesting therapeutic properties. However, its low aqueous solubility and stability resulted in poor availability and restricted the clin. efficacy. Pillar[5]arenes with hydrophilic ends and a hydrophobic cavity could include with BDMC based on size matching. The synthesized hydrazide-pillar[5]arene (HP5A) and BDMC had a strong host-guest interaction with a 1:1 binding stoichiometry. Furthermore, the HP5A ⊃ BDMC complex could self-assemble into well-defined fibers in water/ethanol solution This supramol. complex worked well in vitro for inhibiting the proliferation of hepatoma carcinoma cells HepG2. Remarkably, this method of complexation with pillar[5]arenes visibly reduced the undesirable side effects on normal cells without weakening the anti-cancer activity of the drugs. We expected that the obtained host-guest complex and fibrous assembly would provide a promising platform for delivering drugs with low water solubility This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Formula: C19H16O4).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

And the article was included in Fluid Phase Equilibria in 2003.Name: 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

Isothermal vapor-liquid equilibrium (VLE) phase compositions were measured for four binary systems of carbon dioxide with diethylene glycol di-Et ether, diethylene glycol Bu ether, diethylene glycol hexyl ether, and diethylene glycol di-Bu ether at temperatures from 333.15 to 413.15 K and pressures up to 20 MPa. The saturated vapor composition of the ethers follows the order of diethylene glycol di-Et ether > diethylene glycol Bu ether>diethylene glycol di-Bu ether > diethylene glycol hexyl ether, while the solubility of carbon dioxide in the liquid obeys the sequence of diethylene glycol di-Et ether ≈ diethylene glycol di-Bu ether > diethylene glycol hexyl ether ≈ diethylene glycol Bu ether. Henry’s constants were calculated by fitting the Krichevsky-Ilinskaya (KI) equation to the isothermal equilibrium data. The constants increase with increasing temperature for each binary system.
