On July 31, 2021, Zhou, Luli; Wang, Dingfa; Zhou, Hanlin published an article.Reference of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide The title of the article was Metabolic profiling of two medicinal Piper species. And the article contained the following:

Piper sarmentosum Roxb. (PS) and Piper cathayanum M. G. Gilbert & N. H. Xia (PC) are both listed as Traditional Chinese Medicine herbs. In this study, ultra-performance liquid chromatog. mass spectrometry (UPLC-MS/MS) was used to analyze secondary metabolites and metabolically profile the leaves, stems and roots in PS and PC. A total of 110 and 92 differential metabolites were shared from various organs of PS and PC, resp. Compared to the stems and roots of PS or PC, alkaloids and phenols in leaves of PS or PC accounted for 70% and 57% of the total alkaloids and phenols, resp. An anal. of enriched metabolic pathways demonstrated that L-tyrosine and 4-hydroxycinnamic acid in PS were directly involved in five and three metabolic pathways, which are related to the biosynthesis of isoquinoline alkaloids and phenol backbones, resp. The L-glutamic acid and oxoglutaric acid in PC were involved in seven and two metabolic pathways, resp. L-glutamic acid synthesizes heme, tropane, piperidine and pyridine alkaloids, and the type II polyketide backbone. Moreover, oxoglutaric acid generated via L-glutamic acid was mainly involved in the citrate cycle and played a fundamental role in determining these important metabolic processes. The experimental process involved the reaction of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide(cas: 456-12-2).Reference of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide

Yan, Ni; Long, Shengxing; Xiong, Kangning; Zhang, Ting published an article in 2022, the title of the article was Antibiotic bioaccumulation in zooplankton from the Yelang Lake Reservoir of Anshun City, Southwest China.Application of 144-80-9 And the article contains the following content:

Antibiotic (蟽sulfonamide, 蟽fluoroquinolone, 蟽tetracycline and 蟽macrolide) contamination in aquatic systems has remained a global concern in recent years. In this study, fourteen antibiotics, sulfadiazine (SDZ), sulphapyridine (SPD), sulfacetamide (SCT), sulfamethoxazole (SMX), sulfamethazine (SMZ), trimethoprim (TMP), ofloxacin (OFX), lomefloxacin (LFX), ciprofloxacin (CFX), norfloxacin (NFX), oxytetracycline (OTC), tetracycline (TC), dehydroerythromycin (ETM-H2O) and roxithromycin (RTM), were analyzed in zooplankton collected from the Yelang Lake Reservoir between May 2016 and Mar. 2017. Our results demonstrated that the antibiotic TC (mean 95.80 ng g-1), OTC (mean 167.0 ng g-1) and RTM (mean 151.80 ng g-1) concentrations were significantly higher in zooplankton than the other antibiotics. TC, OTC and RTM accumulated intensively in zooplankton, and the BAFs of OTC, RTM and TC were significantly higher, with mean BAF values of 78.43, 108.4 and 110.1, resp. Antibiotic concentrations were strongly correlated with zooplankton phytoplankton biomass, OTC, RTM and SMX concentrations in zooplankton were significantly pos. correlated with bacillariophyte biomass, and SDZ and SMZ concentrations in zooplankton were significantly pos. correlated with T. brevifurcatus, T. mongolicus, and D. pulex biomass. SPD with P. tunguidus, C. cornuta, TMP, ETM and OFX with P. tunguidus, C. cornuta, M. leuckarti, C. vicinus vicinus, CFX with D. pulex, LFX with T. brevifurcatus, T. mongolicus, Bosmina longirostris, and D. dubium were significantly pos. correlated. These results show that bioaccumulation or scavenging of antibiotics across trophic levels is a fundamental and complex component of antibiotic cycling in aquatic environments. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Application of 144-80-9

On August 5, 2022, Li, Qinlan; Guo, Qian; Wang, Shuyi; Wan, Shanhe; Li, Zhonghuang; Zhang, Jiajie; Wu, Xiaoyun published an article.Application of 16230-24-3 The title of the article was Design and synthesis of proteolysis targeting chimeras (PROTACs) as an EGFR degrader based on CO-1686. And the article contained the following:

Epidermal growth factor receptor (EGFR) inhibitors represent the first-line treatment of non-small-cell lung cancer (NSCLC). However, the emergence of acquired drug resistance and side effects largely encumbered their application in clinic. The emerging technol. proteolysis targeting chimera (PROTAC) could be an alternative strategy to overcome these problems. Herein, we reported the discovery of EGFRL858R/T790M degraders based on CO-1686. Promising PROTAC 1q could effectively and selectively inhibit the growth of PC-9 (EGFRDel 19) and H1975 (EGFRL858R/T790M) cells, but not that of A549 (EGFRWT) cells. In addition, 1q could time- and dose-dependently induce degradation of EGFRL858R/T790M in H1975 cells with a DC50 value of 355.9 nM, while did not show obvious effect on the EGFRDel 19 and EGFRWT protein. Preliminary mechanism study demonstrated that the protein degradation was mediated through ubiquitin-proteasome system (UPS). Furthermore, 1q could significantly induce the apoptosis of H1975 cells and arrest the cells in G0/G1 phase. These findings demonstrated that compound 1q could be used as initial lead compound for the development of new EGFRL858R/T790M degraders based therapy. The experimental process involved the reaction of N-(3-Aminophenyl)acrylamide(cas: 16230-24-3).Application of 16230-24-3

Yuan, Ruiying; Dongzhi, Zhuoma; Guo, Wei; Zhen, Pu; Liu, Zhiming; Huang, Shan; Li, Bin; Yu, Jianqing published an article in , the title of the article was Hepatoprotective effect of Sophora moorcroftiana (Benth.) Benth.Ex baker seeds in vivo and in vitro.HPLC of Formula: 456-12-2 And the article contains the following content:

The leguminosae of Sophora moorcroftiana (Benth.) Benth.ex Baker is a drought-resistant endemic Sophora shrub species from the Qinghai-Tibet Plateau, and its seeds have hepatoprotective effects. To study the effect of S. moorcroftiana seeds on liver injury and the mol. mechanism underlying the beneficial effects, liquid chromatog.-mass spectrometry was used to detect the main active components in the ethanol extract of S. moorcroftiana seeds (SM). Male mice were divided into six groups (n = 8): normal control (NC), CCl4, SM (50, 100, 200 mg/kg), and di-Me di-Ph bicarboxylate (150 mg/kg) groups. Mice were treated as indicated (once/day, orally) for 14 days, and CCl4 (2 mL/kg) was administered i.p. The serum and liver of mice were used for biochem. assays. To explore the underlying mechanism, HepG2 cells were treated with SM, stimulated with tert-Bu hydroperoxide (t-BHP, 50 渭M), and analyzed by Western blotting. The major active compounds of SM were alkaloids including 22 compounds Serum alanine transaminase (ALT), aspartate transaminase (AST), and alk. phosphatase (ALP) decreased in the SM (200 mg/kg) group. SM can activate the expression of pregnane X receptor (PXR) and downstream mols. cytochrome P 4503A11 enzyme (CYP3A11), UDP glucuronosyltransferase 1 family polypeptide A 1 (UGT1A1), and inhibit the multidrug resistance protein 2 (MRP2). In addition, SM improved cell viability in t-BHP-induced HepG2 cells (64% to 83%) and decreased the activation of the mitogen-activated protein kinase (MAPK) pathway. The main compounds in SM were alkaloids. SM showed hepatoprotective effects possibly mediated by the suppression of oxidative stress through the MAPK pathway. The experimental process involved the reaction of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide(cas: 456-12-2).HPLC of Formula: 456-12-2
