Abstract:

Numerous numbers of biologically active agents have been identified for their diverse therapeutic functions. Detailed investigations of phytochemicals for antiviral activities have assumed greater importance in the last few decades. A wide variety of active phytochemicals, including the flavonoids, terpenoids, organosulfur compounds, limonoids, lignans, sulphides, polyphenolics, coumarins, saponins, chlorophyllins, furyl compounds, alkaloids, polyines, thiophenes, proteins and peptides have been found to have therapeutic applications against different genetically and functionally diverse viruses. The antiviral mechanism of these agents may be explained on basis of their antioxidant activities, scavenging capacities, inhibiting DNA, RNA synthesis, inhibition of the viral entry, or inhibiting the viral reproduction etc. Large number candidate substances such as phytochemicals and their synthetic derivatives have been identified by a combination of in vitro and in vivo studies in different biological assays. In this article we have made attempts to extensively review and provide comprehensive description of different phyto-antiviral agents. We have examined the recent developments in the field of plant derived antiviral agents. The major advances in the field of viral interactions in various biological assays have been summarized. In addition sources of origin, major viral studies mechanistic action and phase trials of various phytoantiviral agents have been included in the review.
