Phenolic compounds have been related to multiple biological activities, and the antiviral effect of these compounds has been demonstrated in several viral models of public health concern. In this review, we show the antiviral role of phenolic compounds against dengue virus (DENV), the most widespread arbovirus globally that, after its re-emergence, has caused multiple epidemic outbreaks, especially in the last two years. Twenty phenolic compounds with anti-DENV activity are discussed, including the multiple mechanisms of action, such as those directed against viral particles or viral proteins, host proteins or pathways related to the productive replication viral cycle and the spread of the infection.

Medicinal plants are insufficiently studied and almost endless. The use of phytomedication enables reduce the impact of xenobiotics on animals organism through the natural origin of active compounds and associated and auxiliary substances smoothing the basic action and prevent the manifestation of side effects. One of such plants the possibility of using in veterinary practice is still insufficiently studied is mock–orange. Considering on the important role of phenolic compounds in the metabolic regulation of plant and diversity of impact of these substances on organism of animals and humans, in leaves of mock–oranges different cultivar was identified the content of phenolic secondary metabolites to identify the prospects for their further using in veterinary medicine. The qualitative reaction with the Wilson reagent, solution of iron (III) chloride and by cyanidin reaction in extracts from mock–orange leaves was established the presence of phenolic compounds. Further phytochemical investigations established that the content of phenols in the investigated extracts is between 33.0 ± 0.48 to 107.1 ± 0.91 mg/g (in Philadelphus L. 'Avalanche'). The content of flavonoids in alcohol extracts from leaves of different species of mock–oranges varies from 5.3 ± 0.41 to 10.6 ± 0.41 mg/g. Greatest quantity of flavonoids at relatively of low content of phenols contained in the preparation from leaves of Philadelphus coronaries 'Nana '(mock–orange dwarf), the use of which, along with Philadelphus L. 'Avalanche' can be perspective in medical and veterinary practice, considering on the high concentration of phenols and flavonoids and coumarins in these mock–oranges breed.

Adverse reactions to food such as allergies and celiac disease are increasingly recognized as a growing public health burden. There is currently no cure for these diseases so that there is an unmet need to evaluate different nutritional approaches aiming at improving the quality of life of affected patients and their families. In this context, healthy promising nature-derived compounds, most of which contained in fruits and vegetables, have been studied as an alternative to attenuate the epidemic. Indeed, phenolic compounds have become an emerging field of interest in nutrition in the last decades. A growing build of research suggests that phenolic compounds inhibit pro-inflammatory transcription factors by interacting with proteins involved in gene expression and cell signaling, leading to protective effects against many inflammation-mediated chronic diseases. However, the use of phenolic compounds as attenuating agents of immune reactions to food has to be aligned to the organoleptic characteristics of food, since many compounds present unpleasant taste properties, namely bitter taste and astringency. In this framework, tasty but healthy phenolic compounds arise as attractive ingredients in the design and formulation of functional foods. This book chapter is focused on revisiting the organoleptic properties of phenolic compounds while evaluating the role of these compounds in health promoting actions, namely the management of immune reactions to food such as Food Allergies and Celiac Disease.
