What secondary metabolites that are found in plants has the capacity to inhibit rabies?5 answersGallotannin, a secondary metabolite found in plants like Rhus chinensis and Paeonia suffruticosa, has demonstrated potent antiviral effects against rabies virus. Additionally, phytochemicals such as (+)-catechin from Salix subserrata and kaempferol from onion, as well as compounds like gingerol from Ginger, rosmarinic acid from Selfheal, Rosemary, and Oregano, and gallotannin from Aleppo oak and Chinese nutgall, have shown potential as inhibitors against rabies. Furthermore, Justicia schimperiana, Ricinus communis, and Croton macrostachyus have been identified to contain alkaloids, flavonoids, phenols, steroids, tannins, and terpenoids with antirabies activity. These secondary metabolites present in various plants hold promise for the development of novel antirabies compounds.
What are the specific plant compounds that exhibit antiviral properties against human viruses?5 answersPlant compounds with antiviral properties against human viruses include abietanes like ferruginol analogues, flavonoids, lignans, terpenoids, coumarins, saponins, and alkaloids. Additionally, extracts from plants like Stenocline ericoides and Stenocline inuloides have shown antiviral effects against dengue and Zika viruses. Essential oils from Acacia nilotica bark and fruits contain compounds like caryophyllene oxide, spathulenol, and trans-caryophyllene, which exhibit antiviral activity against HAV, HSV1, and HSV2. Furthermore, extracts from Hedyotis diffusa and Artemisia capillaris have demonstrated inhibitory activity against DENV, ZIKV, and JEV, with potential for clinical applications. These diverse plant compounds showcase promising antiviral properties against a range of human viruses.
Is zanthoxylum bungeanum have antiviral effect?5 answersZanthoxylum bungeanum, commonly known as Sichuan pepper, exhibits various bioactive properties. Research indicates that Z. bungeanum seed proteins contain antioxidant peptides with potential health benefits. Additionally, Z. bungeanum extract has been found to possess antibacterial activity, making it a promising candidate for food biological extracts. Moreover, Z. bungeanum leaf extracts, particularly from Zanthoxylum piperitum, demonstrate broad-spectrum antiviral activity against picornaviruses, including human rhinoviruses and enteroviruses, suggesting its potential as an antiviral agent. Therefore, Zanthoxylum bungeanum shows promise in combating viral infections, highlighting its potential antiviral effects.
Which plants have anti-fungal properties?5 answersPlants with anti-fungal properties include Rhinacanthus nasutus, Andrographis paniculata, Psidium guajava, tansy, yarrow, garlic, horseradish, nettle, Hibiscus Sabdariffa L., Syzygium aromaticum L., and Achillea millefolium L.. These plants have been found to contain bioactive compounds such as antifungal proteins or peptides (AFPs), essential oils, flavonoid derivatives, and organic acids that exhibit strong antimicrobial properties. The antifungal activities of these plants have been tested against various fungi including Candida albicans, Cryptococcus neoformans, Aspergillus fumigatus, and Talaromyces marneffei, and have shown promising results. The essential oils from Thymus vulgaris, Chamaemelum nobile, Ziziphora clinopodioides, Zingiber officinale, and Cuminum cyminum have also demonstrated strong antifungal properties against Aspergillus and Penicillium species. These plants and their bioactive compounds have the potential to be used as therapeutic agents and natural alternatives for controlling fungal infections in both humans and plants.
What plants have antiviral activity against HHV-1?5 answersExtract of Ginkgo biloba (EGb) has shown antiviral activity against HHV-1.
Are there any plant-based treatments that can help to prevent or treat SARS-CoV-2?5 answersPlant-based treatments have shown potential in preventing and treating SARS-CoV-2. Several plant extracts, such as Larrea divaricataCav, have demonstrated anti-inflammatory, immunomodulatory, antimicrobial, and antioxidant activities, making them good candidates for studying the prevention and treatment of SARS-CoV-2. Additionally, plant-derived natural products (PDNPs) like rutin, EGCG, hesperidin, and rosmarinic acid have been found to inhibit the spike glycoproteins of SARS-CoV-2 variants, making them effective against different strains of the virus. Anthraquinones (AQs), found in plants, fungi, and lichens, have also shown anti-viral activity against SARS-CoV-2 enzymes and can block the binding of the virus to host cells. Furthermore, extracts from medicinal plants like Andrographis paniculata, Artemisia annua, and Curcuma longa have been found to impede the adsorption of SARS-CoV-2 to host cells and prevent virus multiplication, while also exerting an immunomodulatory effect. Natural extracts have historically shown effective results against the coronavirus family, including SARS-CoV-1, and continue to be studied for their potential in treating SARS-CoV-2.
