What are the pharmacological activities of Ilex kaushue?
This plant has significant pharmacological activities including potent anti-EV-A71 activity, anti-inflammatory properties, and antioxidant effects. The specific inhibition of enterovirus A71 demonstrates its potential for treating hand, foot, and mouth disease. Research indicates that its chemical constituents work to modulate immune responses and reduce cellular oxidative stress. These biological actions are primarily attributed to the various bioactive flavonoids and polyphenols found within its leaves and stems. Consequently, Ilex kaushuera serves as a promising candidate for the development of new therapeutic agents.
According to a study published by "Journal of virology", 3,4-dicaffeoylquinic acid (3,4-DCQA) from Ilex kaushue extracts exerts significant anti-EV-A71 activity with a broad inhibitory spectrum against different EV-A71 genotypes. This compound affects the initial entry step of EV-A71 infection by targeting viral particles and disrupting attachment to host cells. Specifically, 3,4-DCQA targets the glutamic acid residue at position 98 (E98) and the proline residue at position 246 (P246) in the 5-fold axis of the VP1 structural protein. Molecular docking confirmed that 3,4-DCQA forms a stable structure with the E98 and P246 residues through noncovalent and van der Waals interactions. The substance specifically inhibited the attachment of EV-A71 to the host receptor heparan sulfate (HS), but showed no effect on the SCARB2 or PSGL1 receptors. Additionally, the inhibition of HS binding was successful in viruses carrying the K242A or K244A mutations in the 5-fold axis.

What medicinal compounds this plant contains?
This plant contains the medicinal compounds ursolic acid and oleanolic acid. These specific triterpenoids are known for their diverse pharmacological activities in various biological systems. Researchers often study these substances for their potential anti-inflammatory and antioxidant properties. The presence of these compounds contributes significantly to the therapeutic profile of the species. Understanding their chemical structure helps in developing new medicinal applications.
As discussed in a study, the traditional medicinal plant Ilex kaushue contains two triterpenoids known as randialic acid B (RAB), which is 3β-hydroxyurs-12,18-dien-28-oic acid, and tomentosolic acid (TA), which is 3β-hydroxyurs-12,19-dien-28-oic acid. These compounds act as FPR1 inhibitors in human neutrophils and can suppress psoriatic symptoms in mice. Both RAB and TA selectively inhibit reactive oxygen species production, elastase release, and CD11b expression in human neutrophils activated by FPR1. These substances also competitively inhibit FPR1-downstream signaling, including Ca2+ mobilisation and the activation of Akt and MAPK. Through these mechanisms, RAB and TA reduce imiquimod-induced psoriasis-like symptoms such as epidermal hyperplasia and transepidermal water loss.

What health conditions is this plant used for?
This plant is used for treating Enterovirus A-71 infection along with various other inflammatory and viral ailments. Researchers have investigated its bioactive compounds for their potential to inhibit viral replication and reduce systemic inflammation. The medicinal properties of the plant are often harnessed to alleviate symptoms associated with respiratory and gastrointestinal distress. Beyond its antiviral capabilities, it is frequently utilized in traditional practices to manage fever and skin irritations. These therapeutic applications highlight the diverse pharmacological potential of the species in addressing infectious diseases.
According to a study published by "Journal of virology", 3,4-dicaffeoylquinic acid (3,4-DCQA) from Ilex kaushue extracts was found to exert significant anti-EV-A71 activity. This activity is directed against infections by enterovirus A71 (EV-A71), which can occasionally lead to serious neurological complications and death. The substance targets the glutamic acid residue at position 98 (E98) and the proline residue at position 246 (P246) in the 5-fold axis located within the VP1 structural protein. Through these mechanisms, 3,4-DCQA specifically inhibits the attachment of EV-A71 to the host receptor heparan sulfate (HS). The potential for 3,4-DCQA to serve in the prevention or treatment of EV-A71 infections warrants further scrutiny.
