Somatorelin is 29 amino acid analogue of human growth hormone-releasing hormone used as a diagnostic agent for determining growth hormone deficiency. Growth-hormone-releasing hormone (GHRH, somatoliberin) is the hypothalamic peptide hormone that specifically stimulates synthesis and release of growth hormone (GH, somatotropin) by somatotrope cells of the anterior pituitary gland. The hypothalamic hormone growth hormone (GH)-releasing hormone (GHRH) acts on specific GHRH receptors (GHRH-R) in the anterior pituitary gland to stimulate the synthesis and secretion of GH and to promote somatotrope expansion. Somatorelin is applied to determine the somatotropic function of the anterior pituitary gland in cases of suspected growth hormone deficiency. The test distinguishes between pituitary and hypothalamic disorders but is not suitable as a screening test for growth hormone deficiencies. Somatorelin has been used in trials studying the treatment of Aging, Elderly, Sleep Disorders, Hormone Deficiency, and Mild Cognitive Impairment.

Tetraethylenepentamine (TEPA) is a low-molecular-weight linear polyamine exerting metal-chelating properties. TEPA is widely used in industrial applications. The principal hazards that arise in working with TEPA are those associated with similar organic amines; namely, a corrosive action on skin and eyes. TEPA biological activity was attributed to its effect on cellular Cu levels as (a) treatment with TEPA resulted in reduction of cellular Cu, and (b) excess of Cu reversed TEPA's activity and accelerated differentiation. TEPA was shown to attenuate the differentiation of ex vivo cultured hematopoietic cells resulting in preferential expansion of early progenitors. A phase I/II trial was performed to test the feasibility and safety of transplantation of CD133+ cord blood (CB) hematopoietic progenitors cultured in media containing stem cell factor, FLT-3 ligand, interleukin-6, thrombopoietin and TEPA. Transplanting a population of CD133+ CB cells which were expanded ex vivo for 21 days using SCF, FLT3, IL-6, TPO and the copper chelator TEPA (StemEx) was feasible. The expanded cells were well tolerated, with no infusion-related adverse events observed.

Poliglusam (also commonly known as chitosan) is a linear polysaccharide composed of randomly distributed β-(1→4)-linked D-glucosamine and N-acetyl-D-glucosamine. Commercial Poliglusam is derived from deacetylation of chitin contained in the shells of various sea crustaceans such as shrimps. Chitosan is easily prepared from the second most plentiful natural polymer on earth, so it is no surprise that it is being researched as a key component of so many different biomaterials. Several benefits of Poliglusam, such as biocompatibility, biodegradability, biorenewability, bioadhesivity, and nontoxicity have made them important natural polymers for pharmaceutical and cosmetic industries. Poliglusam and its derivatives are biocompatible in a wide range of applications, from hydrogels promoting angiogenesis to a bread supplement that ameliorates diabetes. Poliglusam is also used within some wound dressings to stop bleeding. In agriculture, chitosan is typically used as a natural seed treatment and plant growth enhancer, and as an ecologically friendly biopesticide substance that boosts the innate ability of plants to defend themselves against fungal infections. As a rich source of dietary fiber, chitosan is used as a food ingredient or additive.
