Ganoderic acid K
Ganoderic acid K is a triterpenoid compound. Ganoderic acid K can be isolated from Ganoderma lucidum. Ganoderic acid K inhibits ACE activity with an IC50 of 2.6×10-5 M. Ganoderic acid K exhibits direct, high-affinity binding to recombinant MD2 protein, with a Kd value of 0.47 μM. It potently inhibits LPS-induced release of TNF-α and IL-6. It reduces cerebral infarction volume and ameliorates neurological dysfunction in mice with ischemic stroke in the tMCAO model. Ganoderic acid K can be used in studies related to hypertension and ischemic stroke.

In Vitro
Ganoderic acid K inhibits the activity of purified porcine kidney angiotensin-converting enzyme, with an IC50 value of 2.6×10-5 M[1].
Ganoderic acid K (25 μM; 1 h pretreatment) potently inhibits LPS-induced release of TNF-α and IL-6 in BV-2 mouse microglia, with inhibition rates of over 50% for both cytokines[2].
Ganoderic acid K (0.19-50 μM) exhibits direct, high-affinity binding to recombinant MD2 protein, with a Kd value of 0.47 μM[2].
