Compound traditional Chinese medicine dermatitis ointment ameliorates inflammatory responses and dysregulation of itch-related molecules in atopic dermatitis was written by Zhang, Rongrong;Zhang, Hongyin;Shao, Shuai;Shen, Yingxin;Xiao, Fengqin;Sun, Jiaming;Piao, Songlan;Zhao, Daqing;Li, Guangzhe;Yan, Mingming. And the article was included in Chinese Medicine (London, United Kingdom) in 2022.Formula: C20H18NO4 This article mentions the following:

Atopic dermatitis (AD) is a chronic inflammatory skin disease accompanied with itchy and scaly rash. Compound traditional Chinese medicine dermatitis ointment (CTCMDO) consists of a mixture of extracts from five plants, which had been used in AD treatment due to good anti-inflammatory and anti-allergic effects. Materials and methods: In this study, high-performance liquid chromatog. (HPLC) and liquid chromatog./mass spectrometer (LC/MS) were performed to analyze the active ingredients of CTCMDO in detail and to establish its HPLC fingerprint. Furthermore, the anti-inflammatory and antipruritic activities of CTCMDO were studied in the treatment of DNCB-induced AD in mice. A total of 44 compounds including phenylpropionic acid compounds, alkaloid compounds, curcumin compounds and lignans were identified via combined HPLC and LC/MS. A fingerprint with 17 common peaks was established. In AD-like mice, DNCB-induced scratching behavior had been suppressed in the treatment of CTCMDO in a dose-dependent manner. Furthermore, the detailed exptl. results indicated that the AD can be effectively improved via inhibiting the production of Th1/2 cytokines in serum, reversing the upregulation of substance P levels of itch-related genes in the skin, and suppressing the phosphorylation of JNK, ERK, and p38 in the skin. This work indicated that CTCMDO can significantly improve AD via attenuating the pathol. alterations of Th1/2 cytokines and itch-related mediators, as well as inhibiting the phosphorylation of mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-κB). In the experiment, the researchers used many compounds, for example, 9,10-Dimethoxy-5,6-dihydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium (cas: 2086-83-1Formula: C20H18NO4).

Although isoquinoline derivatives can be synthesized by several methods, relatively few direct methods deliver the unsubstituted isoquinoline. The discovery of chloroquine, the most well-known drug containing this stent, has helped bring about decades of malaria control and treatment.Formula: C20H18NO4

Rapid identification of absorbed components and metabolites of Gandou decoction in rat plasma and liver by UPLC-Q-TOF-MS^E was written by Xu, Li;Liu, Yi;Wu, Hongfei;Zhou, An. And the article was included in Journal of Chromatography B: Analytical Technologies in the Biomedical and Life Sciences in 2020.Category: isoquinoline This article mentions the following:

Gandou Decoction (GDD), a well-known traditional Chinese medicine prescription, has been widely used for decades in clin. practice to treat Wilson’s disease (WD) in China. However, due to lack of in vivo metabolism research, the absorbed components and metabolites of GDD have not been fully elucidated. In this study, a rapid and high-throughput ultra-performance liquid chromatog. coupled with quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MS^E) was applied to rapidly identify prototypes and metabolites after oral administration of GDD. On this basis, the possible metabolic pathways of the main prototypes were proposed between normal and copper-laden rats. As a result, a total of 89 GDD-related xenobiotics were detected in normal dosed rats, including 83 (36 prototypes and 47 metabolites) in plasma and 52 (21 prototypes and 31 metabolites) in liver; a total of 77 GDD-related xenobiotics were detected in copper-laden dosed rats, including 68 (31 prototypes and 37 metabolites) in plasma and 42 (19 prototypes and 23 metabolites) in liver. Our findings showed that anthraquinones, alkaloids and protostane triterpenoids as well as a few saponins, flavonoids, tannins and curcuminoids were the main absorbed chem. components of GDD in rat plasma; anthraquinones, protostane triterpenoids and curcuminoids were the major components in rat liver. Glucuronidation and sulfation were deduced to be the predominant metabolic pathways of GDD. Methylation, acetylation, reduction, hydroxylation, demethylation and deglycosylation were often occurred in the metabolic process. Furthermore, the holistic metabolic profile of GDD revealed that copper-laden rats and normal rats had certain differences in drug absorption and metabolism This study offered a solid basis for ascertaining bioactive components and action mechanism of GDD. In the experiment, the researchers used many compounds, for example, 9,10-Dimethoxy-5,6-dihydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium sulfate(2:1) (cas: 316-41-6Category: isoquinoline).
