Influenza is a common respiratory infectious disease. In China, Lianhua Qingwen capsule (LHQWC), a drug with significant clinical efficacy and few side effects, is commonly used to treat influenza. However, the composition of LHQWC is complicated, and currently used quality control methods cannot ensure its consistency. In this study, combined with its clinical efficacy, the targets of LHQWC were screened using network pharmacology. Then, anti-inflammation quality markers of LHQWC were screened and judged by combined chemical with biological evaluation. Cyclooxygenase-2 (COX-2) was identified as one of the main targets of the anti-inflammatory activity of LHQWC. The rate of inhibition of COX-2 by different batches of LHQWC was determined. Furthermore, seven components of LHQWC were identified. The potential quality markers were screened by spectral-effect relationship. As a result, chlorogenic acid, isochlorogenic acid B, and isochlorogenic acid C were identified and confirmed as anti-inflammatory quality markers of LHQWC. We hope that these findings provide a scientific basis for the accurate quality control of LHQWC and serve as a reference for the quality control of other drugs.

The author would like to study the effects of ethanol Graptophyllum pictum (L.) Griff extract (EGPE) as anti-inflammation on wistar with experimental hemorrhoids. RCT post-test only design were done on 28 wistar, that were allocated into four groups. The 2nd , 3rd and 4th group were induced with 6% croton oil into anus for three days, the 1st group was not induced. On the 4th day, 1st and 2nd group were given physiologic saline, 3rd and 4th group was given EGPE 100 mg and 300 mg/ kg bw respectively. At the 9th day, before termination, blood was aspirated from retro-ocular region for examination of serum IL-6, COX-2 and TNF-alpha using ELISA method, and SGOT, SGPT, urea and creatinine level. Anus was removed and prepared for microscopic examination to count the leucocyte under 400 HPF. Induction of 6% croton oil was significantly increased TNF-alpha, IL-6, COX-2 and leucocyte count. Treatment with EGPE dose 100 mg and 300 mg/ kg bw significantly reduce TNF-alpha, IL-6, COX-2 and leucocyte count, dose 100 mg was even better than 300 mg except for leucocyte count. SGOT, SGPT, blood urea and creatinine were not significantly different among groups. In conclusion, the EGPE 100 mg and 300 mg have anti-inflammatory effects in hemorrhoids wistar, which can suppress IL-6, COX-2, TNF-alpha, and total leucocytes. The EGPE dose 100 mg is better than dose 300 mg. EGPE save for kidney and liver.

Aim: As part of ongoing studies in developing new anti-inflammatory agents, 2-thioxo-1,2,3,4-tetrahydropyrimidine derivative 1 was synthesized by direct Biginelli condensation and used for the synthesis of novel series of  pyrimidin-2-thione derivatives  (2a-d to 7a-b). Materials and Methods: All compounds were examined for their anti-inflammatory activity using the carrageenan-induced rat paw edema assay in comparison to ibuprofen, as a reference drug. Molecular docking studies were carried out using SYBLYL-X v.2.1 software. Study Design: A series of pyrimidine derivatives were synthesized by a simple and available method leads to a molecule of promising anti-inflammatory activity, the docking studies show good agreement with anti-inflammatory results. Future researches are recommended to assure the importance of these new derivatives for various applications. Place and Duration of Study: Pharmaceutical Organic Chemistry Department and Pharmacology and Toxicology Department, Faculty of Pharmacy, Helwan University, Cairo, Egypt, between February 2018 and March 2019. Results: Compounds showed 61 to 86% anti-inflammatory activity where-as ibuprofen showed 69% activity. Compounds 2a, 2b, 2c, 2d, 3a, 3b, 3c, 3d, 7a, 7b induced strong anti-inflammatory activity, comparable with that of ibuprofen, they showed significantly difference at 4h post-carrageenan. Compound 3c (86%) showed the best result of edema inhibition in rats. Moreover, compounds 1, 2c and 3c were subjected to in vitro enzyme assay investigations against COX-1 and COX-2. All tested compounds showed higher potency towards COX-2 over COX-1. Compound 3c realized higher potency towards COX-2 (IC50= 0.046 μM) than compounds 1(IC50= 0.21 μM) and 2c (IC50=0.11 μM) as well as ibuprofen (IC50= 43.628 μM). Structure-activity relationship (SAR) has been discussed. Conclusion: A series of pyrimidine derivatives were synthesized by a simple and available method gave a molecule of promising anti-inflammatory activity, the docking studies showed good agreement with anti-inflammatory results.

Synthesis And Biological Evaluation

Abstract Three series of 2-(4-methylsulfonylphenyl) indole derivatives have been designed and synthesized. The synthesized compounds were evaluated for their antimicrobial, COX inhibitory and anti-inflammatory activities. Compound 7g was identified to be the most potent antibacterial candidate against strains of MRSA , E. coli, K. pneumoniae, P. aeruginosa, and A. baumannii , respectively with safe therapeutic dose. Compounds 7a-k, 8a-c and 9a-c showed good anti-inflammatory activity with high selectivity toward COX-2 in comparison with reference drugs indomethacin and celecoxib. Compounds 9a-c were found to release moderate amounts of NO to decrease the side effects associated with selective COX-2 inhibitors. A molecular modeling study for compounds 7b, 7h, and 7i into COX-2 active site correlated with results of in vitro COX-2 inhibition assays.

Objective: The inflammation and oxidative stress were related together in the generation of reactive oxygen species, which is responsible for the enhancement of inflammation associated with various chronic diseases. Methods: The aim of this study is to synthezise and characterizes the flavones (2-phenyl-1-benzopyran-4-one) derivatives and analyzed by their docking hypothetical data as an effective anti-inflammatory mediator against cyclooxygenase-2 (COX-2) enzyme. Further, the evaluation of various in vitro antioxidant and anti-inflammatory studies was carried out. Results: The 10 compounds were synthesized and characterized by ultraviolet, infrared, nuclear magnetic resonance, and mass spectroscopic techniques. The docking data results of these 10 flavones derivatives against COX-2 enzymes (Protein Data Bank ID: 3LN1) showed the binding energy ranging between −5.53 kcal/mol and −7.02 kcal/mol when compared with that of the standard diclofenac (−6.34 kcal/mol). The in vitro studies suggest that the lipophilic character of the side chain donor, along with the hydroxyl substituted flavones found to have significant half maximal inhibitory concentration values. Conclusion: Based on these in silico and in vitro evaluation results, these synthesized compounds could act as a promising inhibitor to target the COX- 2 enzyme. Hence, those compounds were effective in the management of chronic diseases by exhibits free radical scavenging and anti-inflammatory property.
