Effects of plant extracts and derivatives on cardiac K, Nav, and Ca channels: a review.

Natural products (NPs) are endless sources of compounds for fighting against several pathologies. Many dysfunctions, including cardiovascular disorders, such as cardiac arrhythmias have their modes of action regulation of the concentration of electrolytes inside and outside the cell targeting ion channels. Here, we highlight plant extracts and secondary metabolites' effects on the treatment of related cardiac pathologies on hERG, Nav, and Cav of cardiomyocytes.

Potential of several triazene derivatives against DENGUE viruses.

Dengue fever is an infectious disease caused by the dengue virus (DENV), an RNA Flavivirus transmitted by the mosquitoes Aedes aegypti and Aedes albopictus widespread in tropical, subtropical and also temperate regions. Symptoms range from a simple cold to a severe, life-threatening haemorrhagic fever. According to the WHO, it affects around 390 million people per year.

Syntheses and crystal structure of 4-[(pyridin-3-yl)diazen-yl]morpholine and 1-[(pyridin-3-yl)diazen-yl]-1,2,3,4-tetra-hydro-quinoline.

Two new heterocyclic 1,2,3-triazenes were synthesized by diazo-tation of 3-amino-pyridine following respectively by coupling with morpholine or 1,2,3,4-tetra-hydro-quinoline. 4-[(Pyridin-3-yl)diazen-yl]morpholine (), CHNO, has monoclinic 2/ symmetry at 100 K, while 1-[(pyridin-3-yl)diazen-yl]-1,2,3,4-tetra-hydro-quinoline (), CHN, has monoclinic 2/ symmetry at 100 K. These 1,2,3-triazene derivatives were synthesized by the organic medium method by coupling reactions of 3-amino-pyridine with morpholine and 1,2,3,4-tetra-hydro-quinoline, respectively, and characterized by H NMR, C NMR, IR, mass spectrometry, and single-crystal X-ray diffraction.

A Novel HPLC Method for Direct Detection of Nitric Oxide Scavengers from Complex Plant Matrices and Its Application to Leaves.

The present study aimed at developing an original pre-column HPLC assay allowing rapid characterization of nitric oxide (NO) scavengers from complex plant extracts. Sodium nitroprusside (SNP) was employed as a NO donor and spiked with an aqueous extract from leaves prior to HPLC analysis. Relying on the ability of radical scavenging constituents to be oxidized upon reaction with radicals, this assay successfully allowed direct identification of three potential NO scavengers, including verbascoside, isoverbascoside, and luteolin-7--diglucuronide.
