Metabolomics study on the toxicity of Annona squamosa by ultraperformance liquid-chromatography high-definition mass spectrometry coupled with pattern recognition approach and metabolic pathways analysis

Ethnopharmacological relevance Annona squamosa Linn (Annonaceae) is a commonly used and effective traditional Chinese medicine (TCM) especially in the South China. The seeds of Annona squamosa Linn (SAS) have been used as a folk remedy to treat “malignant sores” (cancer) in South of China, but they also have high toxicity on human body. Aim of the study To discover the potential biomarkers in the mice caused by SAS. Materials and methods We made metabonomics studies on the toxicity of SAS by ultraperformance liquid-chromatography high-definition mass spectrometry coupled with pattern recognition approach and metabolic pathways analysis. Results The significant difference in metabolic profiles and changes of metabolite biomarkers between the Control group and SAS group were well observed. 11 positive ions and 9 negative ions (P<0.05) were indicated based on UFLC-QTOF-HDMS. The metabolic pathways of SAS group are discussed according to the identified endogenous metabolites, and eight metabolic pathways are identified using Kyoto Encyclopedia of Genes and Genomes (KEGG). Conclusions The present study demonstrates that metabonomics analysis could greatly facilitate and provide useful information for the further comprehensive understanding of the pharmacological activity and potential toxicity of SAS in the progress of them being designed to a new anti-tumor medicine. One of the oldest and most widely used commercial enzyme inhibitors is aspirin, Quality Control of 1-(4-Methoxyphenyl)-1H-pyrrole-2,5-dione, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 1081-17-0

Nematocidal activity of isoquinoline alkaloids against a species of Diplogastridae

We examined the nematocidal activity of various isoquinoline alkaloids. The method of evaluating nematocidal activity involved the microscopic examination of the state of larvae after the compound was administered to determine the minimum lethal concentration (MLC). In addition, cytotoxic activity (IC50) was examined using HL-60 culture cells. The compound dehydrocorydaline was found to have considerable nematocidal activity and weak cytotoxicity; its cytotoxicity value was equal to that of thiabendazole. We conclude that dehydrocorydaline, with its attractive balance between nematocidal activity and weak cytotoxicity, is the most promising of the tested compounds as a possible remedy for parasitic diseases.

Characterization of aromatase binding agents from the dichloromethane extract of Corydalis yanhusuo using ultrafiltration and liquid chromatography tandem mass spectrometry

Aromatase represents an important target for the treatment of hormone-dependent breast cancer. In the present study, nine alkaloids from the dichloromethane extract of Corydalis yanhusuo were identified by liquid chromatography tandem mass spectrometry (LC-MS/MS) and tested for their aromatase binding activities using an ultrafiltration LC-MS method by investigating the differences of peak areas of compounds before and after incubations with aromatase. It was demonstrated that the quaternary protoberberine alkaloids and the tertiary protoberberine alkaloids exhibited potent aromatase binding activities. The quaternary ammonium group and the methyl group at C-13 position of tertiary protoberberine alkaloids might be necessary for the activity. The findings should provide guidance for the discovery of potential aromatase inhibitors from natural products.

A facile and economical procedure for the synthesis of maleimide derivatives using an acidic ionic liquid as a catalyst

Seven maleimide derivatives were synthesized in good yields and high purity from the corresponding maleamic acids using a Bronsted acidic room temperature ionic liquid (RTIL) as a catalyst. The products were obtained through merely a decanting and removal of the solvent, suggesting that this procedure is superior to the conventional routes, in which the strong organic/inorganic acids were used as the catalysts, as well as a complicated post-processing procedure for the separation and purification of the products was employed.
