Extensive research in the last decade has defined that most chronic diseases display dysregulation of multiple cell signaling pathways that have been linked to inflammation. Neuroinflammation is reaction of living nervous tissue to injury. It may be initiated in response to neurological disease. Including infection, traumatic brain injury, toxic metabolites and autoimmunity. The natural compoun...

Photo-labile molecules have been widely used not only in organic synthesis but also in biological study. The chemistry of the typical photo-labile organic molecules, including their structure, mechanism underlying their photo-lability and strategies to integrate them with biomolecules, is reviewed to illustrate the structural basis for photo-activable caged compounds. Biological applications of...

The paper is an attempt to reveal a relation between the structure and biological activity. Topological properties of molecular electrostatic potentials were investigated. These properties are represented by tree graphs. Based on known experimental data concerning biological activity of a series of various compounds, a relation between the biological activity and the characteristics of the tree...
