Abstract
Structure-activity relationships study was performed for a few series of cyclooxygenase-2 (COX-2) inhibitors by using the Electronic-Topological Method combined with Neural Networks (ETM-NN). Specific molecular fragments were found for active compounds (activity features) from both series by the ETM application. After this, a system of prognosis was developed as the result of training Kohonens selforganizing maps (SOM) by the fragments. From the detailed analysis of all compounds under study, requirements necessary for a compound to be COX-2 inhibitor were formulated. The analysis showed that any requirements violation for a molecule resulted in a considerable decrease or even complete loss of its activity. The found activity features identified correctly different marketed drugs and new compounds that had passed pre-clinical and clinical trials; this fact confirms the workability of the system developed for the COX-2 inhibitory activity prediction.

Bioprospecting of Natural Products as Sources of New Multitarget Therapies
According to the Convention on Biological Diversity, bioprospecting is the exploration of biodiversity and indigenous knowledge to develop commercially valuable products for pharmaceutical and other applications. Bioprospecting involves searching for useful organic compounds in plants, fungi, marine organisms, and microorganisms. Natural products traditionally constituted the primary source of more than ...read more
Drugs and mitochondria
Mitochondria play a central role in the life and death of cells. They are not merely the center for energy metabolism but are also the headquarters for different catabolic and anabolic processes, calcium fluxes, and various signaling pathways. Mitochondria maintain homeostasis in the cell by interacting with reactive oxygen-nitrogen species ...read more
Mitochondria as a Therapeutic Target in Metabolic Disorders
Mitochondria are the primary site of adenosine triphosphate (ATP) production in mammalian cells. Moreover, these organelles are an important source of reactive oxygen and nitrogen species in virtually any nucleated cell type. The modulation of a myriad of cellular signaling pathways depends on the mitochondrial physiology. Mitochondrial dysfunction is observed ...read more
