Abstract
Transient Receptor Potential (TRP) cation channels participate in several processes of vital importance in cell and organism physiology, and have been demonstrated to participate in the detection of sensory stimuli. The thermo TRPs reviewed: TRPV1 (vanilloid 1), TRPM8 (melastatin 8) and TRPA1 (ankyrin-like 1) are known to integrate different chemical and physical stimuli such as changes in temperature and sensing different irritant or pungent compounds. However, despite the physiological importance of these channels the mechanisms by which they detect incoming stimuli, how the sensing domains are coupled to channel gating and how these processes are connected to specific structural regions in the channel are not fully understood, but valuable information is available. Many sites involved in agonist detection have been characterized and gating models that describe many features of the channels behavior have been put forward. In this review we will survey some of the key findings concerning the structural and molecular mechanisms of TRPV1, TRPA1 and TRPM8 activation.

From Biodiversity to Chemical Diversity: Focus of Flavonoids
Flavonoids are the largest group of polyphenols, plant secondary metabolites arising from the essential aromatic amino acid phenylalanine (or more rarely from tyrosine) via the phenylpropanoid pathway. The flavan nucleus is the basic 15-carbon skeleton of flavonoids (C6-C3-C6), which consists of two phenyl rings (A and B) and a heterocyclic ...read more
