Found in most species of the animal kingdom, the endocrine system consists of glands that secrete hormones, and receptors that detect and react to the hormones. In response to environmental stimuli, the endocrine system secretes hormones and uses them as chemical messengers to orchestrate physiological, developmental and reproductive changes that affect the entire body for a long period of time. In order to maintain the proper functioning of the body through its entire life cycle, the endocrine system utilizes a complex feedback mechanism to fine-tune the balance of hormones in the bloodstream. Even a slight disruption to endocrine system’s function can throw off the delicate balance of hormones in the human body and lead to an endocrine disorder, or endocrine disease, such as diabetes, adrenal insufficiency, hyper- or hypothyroidism, and polycystic ovary syndrome (PCOS).

    Sequoyitol 523-92-2 98.0%
    Sequoyitol (5-O-Methyl-myo-inositol) is an orally active hypoglycemic agent and antioxidant. Sequoyitol can be isolated from herbaceous plants. Sequoyitol downregulates the expression of NF-κB and TGF-β1, reduces ROS production and malondialdehyde levels, and enhances total antioxidant capacity. Sequoyitol activates the insulin signaling pathway, including the phosphorylation of IR, IRS1 and Akt. Sequoyitol increases serum insulin levels, inhibits hepatic glucose production, and promotes cellular glucose uptake. Sequoyitol antagonizes TNFα-induced inhibition of the insulin signaling pathway, and decreases blood urea nitrogen and serum creatinine levels. Sequoyitol elicits potential peaks in the chemosensors of adult and larval Atrophaneura alcinous, and acts as an oviposition stimulant for female Atrophaneura alcinous. Sequoyitol can be used in research related to type 2 diabetes, insulin resistance, hyperglycemia, impaired glucose tolerance and diabetic nephropathy.
