Crustecdysone (20-Hydroxyecdysone) is a naturally occurring ecdysteroid hormone isolated from Cyanotis arachnoides C.B.Clarke which controls the ecdysis (moulting) and metamorphosis of arthropods, it inhibits caspase activity and induces autophagy via the 20E nuclear receptor complex, EcR-USP.Crustecdysone exhibits regulatory or protective roles in the cardiovascular system.

The complex process of wound healing is a major problem associated with diabetes, venous or arterial disease, old age and infection. A wide range of pharmacological effects including anabolic, anti-diabetic and hepato-protective activities have been attributed to Ecdysterone. In earlier studies, Ecdysterone has been shown to modulate eNOS and iNOS expression in diabetic animals and activate osteogenic differentiation through the Extracellular-signal-Regulated Kinase (ERK) pathway in periodontal ligament stem cells. However, in the wound healing process, Ecdysterone has only been shown to enhance granulation tissue formation in rabbits. There have been no studies to date, which elucidate the molecular mechanism underlying the complex cellular process involved in wound healing. The present study, demonstrates a novel interaction between the phytosteroid Ecdysterone and Nitric Oxide Synthase (NOS), in an Epidermal Growth Factor Receptor (EGFR)-dependent manner, thereby promoting cell proliferation, cell spreading and cell migration. These observations were further supported by the 4-amino-5-methylamino- 2′ ,7′ -difluorofluorescein diacetate (DAF FM) fluorescence assay which indicated that Ecdysterone activates NOS resulting in increased Nitric Oxide (NO) production. Additionally, studies with inhibitors of both the EGFR and ERK, demonstrated that Ecdysterone activates NOS through modulation of EGFR and ERK. These results clearly demonstrate, for the first time, that Ecdysterone enhances Nitric Oxide production and modulates complex cellular processes by activating ERK1/2 through the EGF pathway.

The polyhydroxylated phytosteroid ecdysterone is present in various plants (e.g. spinach). It is widely marketed as the active component of dietary supplements, due to its reported health and performance promoting effects. For evaluation of its actual bioavailability, a fast and sensitive method was developed, optimized and validated for human serum. Instrumental analysis was performed utilizing liquid chromatography-tandem mass spectrometry with positive electrospray ionization and acquisition in multiple reaction mode. Solid phase extraction and dilute-and-inject (following protein precipitation) were tested to isolate ecdysterone from human serum. Both methods were compared in the light of the preset analytical target profile. The limit of detection (LOD) and quantitation (LOQ) for ecdysterone in human serum after SPE extraction corresponded to 0.06 ng/mL and 0.14 ng/mL, respectively, meeting the requested sensitivity of the method. The assay was linear over the range of 0.10 ng/mL to 20.83 ng/mL. As expected, the sensitivity of the SPE method was better than that of the dilute-and-inject procedure, which did not allow for quantitation of all post administration serum samples. Accuracy (relative error; %) and precision (coefficient of variation; %), were both within acceptance criteria (<15%). The developed method was successfully applied to a ten week intervention study conducted in young men performing regular resistance training. Different doses of supplements containing ecdysterone from spinach extract have been administered during the study and the quantitation of ecdysterone in serum samples has been successfully conducted. Ecdysterone could be quantified in all post-administration samples using solid phase extraction (SPE) for sample pretreatment.

Development of oral mucositis represents a rate-limiting factor in radiation therapy for the treatment of head and neck, as well as other cancers. In this work, we investigated the treatment effect of ecdysterone (a steroid derived from the dry root of Achyranthes bidentate) on radiation-induced oral mucositis, and examined possible underlying mechanisms. Male Sprague-Dawley rats were exposed to 20 Gy X-ray irradiation (single dose, cranial localization) to induce oral mucositis. Possible therapeutic effects of ecdysterone on radiation-induced oral mucositis were investigated by monitoring weights, direct observations, visual scoring method and evaluation of hematoxylin and eosin staining. Assessments of leukocyte common antigen and proliferating cell nuclear antigen staining were also performed in the damaged areas of tongues harvested after irradiation, and changes in signaling pathways were investigated using Western blotting. The development and progression of radiation-induced oral mucositis in this model was similar to that observed in clinic patients. Ecdysterone effectively improved radiation-induced oral mucositis as assessed by direct observation and histopathology, and also increased proliferation of matrix cells, since the Ras-Raf-ERK signal pathway was found to be activated by its use. It was concluded that orally administered ecdysterone accelerated the healing process in a rat model of radiation-induced oral mucositis by upregulating the Ras-Raf-ERK signal pathway.
