Oral and i.m. administration of berberine sulfate decreased serum cholesterol levels and increased duration of pentobarbitone sleeping time in rats. Male rats were divided into 2 groups of 15 each and average initial weight, serum cholesterol level, and pentobarbitone sleeping time (pentobarbitone Na, 40 mg/kg i.p.) were recorded. The initial average serum cholesterol level was 56 mg % and pentobarbitone sleeping time was 90 min. After 3 weeks of daily administration of berberine, the serum cholesterol levels were lowered by 35% and 25% and the pentobarbitone sleeping time was prolonged by 41% and 35% in the 20 mg/kg oral and 2 mg/kg i.m. groups, resp.

Objectives: To analyze the therapeutic effect of fasudil hydrochloride on serum high-mobility group B1 (HMGBl), soluble CD40L (sCD40L) and monocyte chemotactic factor 1 (MCP1) of aged patients with cerebral infarction. Methods: 146 Patients were divided into control group (conventional treatment) and observation group (fasudil hydrochloride combined with conventional treatment), each n = 73. The expression of serum HMGBl, sCD40L and MCP1 was detected by ELISA. Results: The total efficiency of both groups was statistically different (P < 0.05).

The mechanistic pathway involved in-situ formation of aryl radical anion intermediate and progressed via a single electron transfer (SET) mechanism. The wide substrate scope, high functional group forbearance, control/competition experiments, gram-scale synthesis and kinetic studies signified the prominence and useful nature of the protocol along with the steadiness of the novel organocatalyst.

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

Berberine treats atherosclerosis via a vitamin-like effect down-regulating Choline-TMA-TMAO production pathway in gut microbiota was written by Ma, Shu-Rong;Tong, Qian;Lin, Yuan;Pan, Li-Bin;Fu, Jie;Peng, Ran;Zhang, Xian-Feng;Zhao, Zhen-Xiong;Li, Yang;Yu, Jin-Bo;Cong, Lin;Han, Pei;Zhang, Zheng-Wei;Yu, Hang;Wang, Yan;Jiang, Jian-Dong. And the article was included in Signal Transduction and Targeted Therapy in 2022.Application In Synthesis of 9,10-Dimethoxy-5,6-dihydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium This article mentions the following:

Trimethylamine-N-oxide (TMAO) derived from the gut microbiota is an atherogenic metabolite. This study investigates whether or not berberine (BBR) could reduce TMAO production in the gut microbiota and treat atherosclerosis. Effects of BBR on TMAO production in the gut microbiota, as well as on plaque development in atherosclerosis were investigated in the culture of animal intestinal bacterial, HFD-fed animals and atherosclerotic patients, resp. We found that oral BBR in animals lowers TMAO biosynthesis in intestine through interacting with the enzyme/co-enzyme of choline-trimethylamine lyase (CutC) and flavin-containing monooxygenase (FMO) in the gut microbiota. This action was performed by BBR’s metabolite dihydroberberine (a reductive BBR by nitroreductase in the gut microbiota), via a vitamin-like effect down-regulating Choline-TMA-TMAO production pathway. Oral BBR decreased TMAO production in animal intestine, lowered blood TMAO and interrupted plaque formation in blood vessels in the HFD-fed hamsters. Moreover, 21 patients with atherosclerosis exhibited the average decrease of plaque score by 3.2% after oral BBR (0.5 g, bid) for 4 mo (*P < 0.05, n = 21); whereas the plaque score in patients treated with rosuvastatin plus aspirin, or clopidogrel sulfate or ticagrelor (4 mo, n = 12) increased by 1.9%. TMA and TMAO in patients decreased by 38 and 29% in faeces (*P < 0.05; *P < 0.05), and 37 and 35% in plasma (***P < 0.001; *P < 0.05), after 4 mo on BBR. BBR might treat atherosclerotic plaque at least partially through decreasing TMAO in a mode of action similar to that of vitamins.
