Short synthesis of the common trisaccharide core of kankanose and kankanoside isolated from Cistanche tubulosa
A short synthetic approach was developed for the synthesis of a common trisaccharide core found in kankanose, kankanoside F, H1, H2, and I isolated from the medicinally active plant Cistanche tubulosa. All glycosylations were carried out under nonmetallic reaction conditions. Yields were very good in all intermediate steps.
متن کاملIntravenous administration of ghrelin stimulates growth hormone secretion in vagotomized patients as well as normal subjects.
OBJECTIVE Ghrelin is a potent peptide stimulating GH secretion. Besides its direct action on the pituitary, ghrelin has been reported to stimulate GH release via the vagal afferent nerve in rats. To examine the involvement of vagal nerve in ghrelin-induced GH secretion in humans, GH responses to ghrelin were compared between vagotomized patients with gastrectomy and normal subjects. METHODS G...
متن کاملEffectiveness of the combinational treatment of Laminaria japonica and Cistanche tubulosa extracts in hair growth
Since scalp hair loss has increased recently even in young people, seriously affecting individual's quality of life, the hair growth-stimulating effects of Laminaria japonica extract (LJE) and Cistanche tubulosa extract (CTE) were investigated. After confirming anagen phase of follicles under shaving, male C57BL/6 mice were dermally applied with 3% Minoxidil or orally administered with the comb...
متن کاملActivation of growth hormone releasing hormone (GHRH) receptor stimulates cardiac reverse remodeling after myocardial infarction (MI).
Both cardiac myocytes and cardiac stem cells (CSCs) express the receptor of growth hormone releasing hormone (GHRH), activation of which improves injury responses after myocardial infarction (MI). Here we show that a GHRH-agonist (GHRH-A; JI-38) reverses ventricular remodeling and enhances functional recovery in the setting of chronic MI. This response is mediated entirely by activation of GHRH...
متن کاملGhrelin induces growth hormone (GH) secretion via nitric oxide (NO)/cGMP signaling.
Ghrelin, a recently discovered 28-aa peptide, stimulates GH release through a mechanism involving PLC- and cAMP-related signaling pathways. Recently, nitric oxide (NO) and its mediator, cGMP, have been shown to be required for the response of somatotropes to various regulators (GHRH, somatostatin, leptin). Here, we explore the possible role of the NO synthase (NOS)/NO/guanylate cyclase (GC)/cGM...
