Adenocarpus cincinnatus (Ball) Maire

Methyl rosmarinate is an orally active hydroxycinnamic acid. Methyl rosmarinate exhibits an IC₅₀ of 24.70 μM and a K_i of 15.29 μM against PTP1B, an IC₅₀ of 41.46 μg/mL against BChE, a K_i of 0.61 mM against mushroom tyrosinase, and an IC₅₀ of 2.50 μM against SARS-CoV-2 3CLpro. Methyl rosmarinate downregulates the phosphorylation levels of ERK, JNK, p38, Smad2 and Smad3. Methyl rosmarinate activates erythrocyte BPGM and promotes the production of 2,3-BPG. Methyl rosmarinate induces apoptosis of fibroblasts. Methyl rosmarinate prolongs the survival time of hypoxic mice. Methyl rosmarinate improves insulin sensitivity. Methyl rosmarinate binds to SARS-CoV-2 3CLpro and inhibits viral replication. Methyl rosmarinate induces glioblastoma cell death. Methyl rosmarinate activates the TGR5/AMPK axis and reduces the levels of ROS and MDA. Methyl rosmarinate shows inhibitory activity against MMP-1. Methyl rosmarinate can be used in research related to pulmonary fibrosis, hypoxia-induced injury, type 2 diabetes, Alzheimer's disease, hyperpigmentation disorders, COVID-19, glioblastoma and myocardial ischemia-reperfusion injury.

Enmein is isolated from I. serra with immunosuppressive effect.

Serrin A is an immunosuppressive ent-kaurene diterpenoid. Serrin A can be isolated from the aerial parts of Isodon serra.

Anisocoumarin H is a coumarin that exhibits antifungal activity. Anisocoumarin H shows the activities against Microsporum gypseum, Trichophyton rubrum and Trichophyton mentagrophytes with MICs of 62.5 µg/mL.

Rabdoserrin A is a diterpenoid. Rabdoserrin A has antifungal activity.

Carpalasionin is a natural product derived from Rabdosia serra. Rabdosia serra is an important component of Chinese herbal teas, traditionally used to research hepatitis, jaundice, cholecystitis and colitis.

Lasiodonin is a diterpenoids compound isolated from Isodon lasiocarpus.

Methyl rosmarinate is a noncompetitive tyrosinase inhibitor which is isolated from Rabdosia serra, with an IC50 of 0.28 mM for mushroom tyrosinase, and also inhibits a-glucosidase.
