prevention of HCV entry and infection in cell culture was also PDE5 list reported in ex vivo studies (Hossan et al. 2018). In addition, the plant is also reported for any potent anti-HIV compound and in Ranikhet illness virus (Pandey et al. 2005). In an in silico study, the compound boeravisterol found in B. diffusa was evaluated against Mpro and was discovered to possess therapeutic properties against COVID-19 (Rutwick Surya and Praveen 2021). Additional, no acute and sub-acute toxicity was reported from B. diffusa root extract at the dose of 200 mg/kg in Wistar rats (Karwasra et al. 2016).Production of white blood cells and weight of the lymphoid organs were also enhanced inside the groups that received 10 mg/kg nanocurcumin (Afolayan et al. 2018). Curcumin has been reported effective against a lot of enveloped viruses, which includes respiratory viruses like influenza A and respiratory syncytial virus (Praditya et al. 2019). Curcumin might interfere the entry of form A influenza virus by its interaction using the receptor binding region or interfering with viral haemagglutination protein (Ou et al. 2013). The monoacetylcurcumin, a structural analogue of curcumin on Akt phosphorylation, is needed for propagation of influenza A virus (Richart et al. 2018). An in vitro study of curcumin reported capability to inhibit gene κ Opioid Receptor/KOR Synonyms replication of hepatitis B virus (HBV) by inhibiting cccDNA-bound histone acetylation, and it has the potential to be developed as a cccDNAtargeting antiviral agent for hepatitis B (Wei et al. 2017). Furthermore, a study reported that curcumin inhibits 3CL protease activity in SARS-CoV, an critical composition for viral replication (Wen et al. 2007). Taking leads from earlier research, a recent docking study on SARS-CoV-2 reports the possible of curcumin in inhibiting SARS-CoV-2 into lung cells by disrupting the interaction of S protein and ACE2 (Rajagopal et al. 2020; Pandey et al. 2020). This shows the prospective of curcumin within the disruption of SARS-CoV-2 virus entry and replication which can be also related together with the activation of the nuclear aspect erythroid 2 elated factor two (NRF2) pathway (Thimmulappa et al. 2021). C. longa and its phytoconstituents are discovered to be protected in different clinical research (T nesen et al. 2002; Maheshwari et al. 2006; Aggarwal et al. 2016; Thimmulappa et al. 2021).Embelia ribes Burm. (Vidang)E. ribes is often a frequently made use of anthelmintic conventional remedy (Bhandari et al. 2002). It’s reported to possess antimicrobial, antidiabetic, antioxidant, anti-inflammatory, analgesic, contraceptive and antipsychotic activity as well as made use of in acute respiratory distress syndrome (Bhandari et al. 2002; Harish et al. 2012; Shirole et al. 2015; Durg et al. 2017). Embelin, the significant phytoconstituent of E. ribes, was examined in an in silico molecular docking study. The study showed that the binding web page for embelin is situated inside the RBD of viral haemagglutinin which could be utilized for the improvement of a plant-based anti-influenza agent (Bachmetov et al. 2012). A further important polyphenol present inside the plant is quercetin. It really is reported for diverse antiviral activities against influenza virus (H1N1) and HCV. Quercetin inhibits the HCV NS3 protease and reduces viral production by inhibiting both NS3 and heat shock proteins which are crucial for HCV replication (Bachmetov et al. 2012). Quercetin is reported for viral step inhibition of internal ribosome entry web site translation, NS5A protein levels, HCV replication, HCV production and putative vira
