Pharmacological evaluation of Continentalic acid for antidiabetic potential

Biomed Pharmacother 2021 Jun;138:111411.PMID:33711550DOI:10.1016/j.biopha.2021.111411.

Background: Diabetes is a complex endocrine and metabolic disorder. Continentalic acid is a natural drug product found in roots of Aralia continentalis (family Araliaceae), which used in traditional medicine for treatment of rheumatic arthritis, lumbag, lameness, inflammation, gastritis, nephritis and diabetes mellitus. Purpose: This study is aim to investigate the Continentalic acid anti-diabetic potential. Methods: In-silico, in-vitro, in-vivo and molecular techniques were used to investigate various effects of Continentalic acid by Auto Doc Vina, α-amylase and α-glucosidase inhibitory assay and alloxan-induced diabetes rats model. Results: In-silico results revealed that Continentalic acid exhibits binding energy values of - 5 to - 9.3Kcal/mol against selected targets. In-vitro assay showed that Continentalic acid caused α-amylase and α-glucosidase enzymes inhibition. In-vivo finding exhibits that Continentalic acid (50 mg/kg) decreased blood glucose level, body weight, oral glucose tolerance overload, glycosylated hemoglobin, triglycerides, total cholesterol, low density lipoprotein, aspartate transaminase, aspartate aminotransferase, alkaline phosphate, total bilirubin and increased high density lipoprotein (P < 0.05, P < 0.01, P < 0.001 vs. diabetic control group). In animals pancreas and liver tissues, Continentalic acid enhanced glutathione-s-transferase, reduced glutathione, catalase and decreased lipid hydroperoxide level, improved cellular architecture in histopathological examination and decrease expression of inflammatory markers: cyclooxygenase 2, tumor necrosis factor alpha, phosphorylated-nuclear factor kappa B, prostaglandins E2, interleukin-18 and increased heme oxygenase-1, as evidenced in immunohistochemistry and enzyme-linked immunosorbent assay molecular investigations. Conclusions: This study shows that Continentalic acid exhibited binding affinities against the different targets and anti-diabetic action, mediated possibly through α-amylase and α-glucosidase inhibition, anti-hyperlipidemic, hepatoprotection, antioxidant and anti-inflammatory pathways.

Anticancer Activity of Continentalic acid in B-Cell Lymphoma

Molecules 2021 Nov 12;26(22):6845.PMID:34833935DOI:10.3390/molecules26226845.

Aralia continentalis has been used in Korea as a folk remedy for arthralgia, rheumatism, and inflammation. However, its anti-lymphoma effect remains uncharacterized. Here, we demonstrate that A. continentalis extract and its three diterpenes efficiently kill B-lymphoma cells. Our in vitro and in vivo results suggest that the cytotoxic activities of Continentalic acid, a major diterpene from A. continentalis extract, are specific towards cancer cells while leaving normal murine cells and tissues unharmed. Mechanistically, Continentalic acid represses the expression of pro-survival Bcl-2 family members, such as Mcl-1 and Bcl-xL. It dissociates the mitochondrial membrane potential, leading to the stimulation of effector caspase 3/7 activities and, ultimately, cell death. Intriguingly, this agent therapeutically synergizes with roflumilast, a pan-PDE4 inhibitor that has been successfully repurposed for the treatment of aggressive B-cell malignancies in recent clinical tests. Our findings unveiled that A. continentalis extract and three of the plant's diterpenes exhibit anti-cancer activities. We also demonstrate the synergistic inhibitory effect of Continentalic acid on the survival of B-lymphoma cells when combined with roflumilast. Taken in conjunction, Continentalic acid may hold significant potential for the treatment of B-cell lymphoma.

Continentalic acid Rather Than Kaurenoic Acid Is Responsible for the Anti-Arthritic Activity of Manchurian Spikenard In Vitro and In Vivo

Int J Mol Sci 2019 Nov 4;20(21):5488.PMID:31690022DOI:10.3390/ijms20215488.

The aim of this study was to identify the active compound responsible for the pharmacological activities of Manchurian spikenard (Aralia continentalis Kitag.). Interleukin (IL)-1β-stimulated human chondrocytes and monoiodoacetate (MIA)-induced osteoarthritic rats were treated with the 50% ethanolic extract of spikenard or its major components, such as Continentalic acid (ent-pimara-8(14),15-diene-19-oic acid) and kaurenoic acid (ent-kaura-16-en-19-oic acid). The spikenard extract significantly inhibited IL-1β-stimulated production of IL-6, IL-8, metalloproteinase (MMP)-1, MMP-13, cyclooxygenase (COX)-2, inducible nitric oxide synthase (iNOS) and prostaglandin(PG)E2 in a dose-dependent manner but not MMP-3 production. The extract also inhibited the IL-1β-induced translocation of NF-κB/p65 into the nucleus and dose-dependent phosphorylation levels of extracellular signal-regulated kinase (ERK), Jun amino-terminal kinase (JNK) and p38 mitogen-activated protein (MAP) kinase. Continentalic acid exhibited significant anti-arthritic activity corresponding exactly to that of the extract containing an equivalent amount of Continentalic acid. On the other hand, kaurenoic acid exhibited a compatible activity at about a 10-times higher molar concentration than that of Continentalic acid. In vitro anti-arthritic activities of the spikenard extract and Continentalic acid were also confirmed in MIA-induced osteoarthritic rats. The 50% ethanolic extract of Manchurian spikenard exhibited promising anti-arthritic activities in the in vitro and in vivo osteoarthritis models, and Continentalic acid, not kaurenoic acid, was most probably responsible for those activities.

Continentalic acid from Aralia continentalis shows activity against methicillin-resistant Staphylococcus aureus

Phytother Res 2006 Jun;20(6):511-4.PMID:16619343DOI:10.1002/ptr.1894.

In a continuing search for compounds with antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA), a chloroform extract of roots of Aralia continentalis was found to contain Continentalic acid (CA, C(20)H(30)O(2)), a diterpenic acid. This compound exhibited potent activity against standard methicillin-susceptible Staphylococcus aureus (MSSA) as well as clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA). It was determined that Continentalic acid had minimum inhibitory concentrations (MICs) of approximately 8-16 microg/mL against S. aureus, including the MSSA and MRSA standard strains. Therefore, the results obtained in this study suggest that Continentalic acid might have potential as an adjunct in the treatment of antibiotic-resistant bacteria.

Continentalic acid exhibited nephroprotective activity against the LPS and E. coli-induced kidney injury through inhibition of the oxidative stress and inflammation

Int Immunopharmacol 2020 Mar;80:106209.PMID:32004924DOI:10.1016/j.intimp.2020.106209.

The present study investigated the effect of the Continentalic acid (CNT) isolated from the Aralia Continentalis against the LPS and E. coli-induced nephrotoxicity. The LPS and E. coli administration markedly altered the behavioral parameters including spontaneous pain, tail suspension and survival rate. However, the treatment with CNT dose dependently improved the behavioral parameters. The CNT treatment significantly improved the renal functions test (RFTs) and hematological parameters following LPS and E. coli-induced kidney injury. Furthermore, the LPS and E. coli administration markedly compromised the anti-oxidant enzymes and enhanced the oxidative stress markers. However, the CNT treatment markedly enhanced the anti-oxidants enzymes such as GSH, GST, Catalase and SOD, while attenuated the oxidative stress markers such as MDA and POD. The MPO enzyme is widely used marker for the neutrophilic infiltration, the LPS and E. coli administration markedly increased the MPO activity. However, the CNT treatment markedly attenuated the MPO activity in both LPS and E. coli-induced kidney injury. Furthermore, the CNT treatment markedly attenuated the NO production compared to the LPS and E. coli-induced kidney injury group. Additionally, the CNT treatment improved the histological parameters markedly (H and E, PAS and Masson's trichome staining) and protect the kidney from the inflammatory insult of the LPS and E. coli evidently. The comet assay revealed marked DNA damage, however, the CNT treatment markedly prevented the LPS and E. coli-induced kidney damage. The CNT treatment markedly enhanced the expression of Nrf2, while attenuated the iNOS expression in both models of kidney injury.
