pramlintide (acetate hydrate)

Pramlintide is a non-amyloidogenic analog of the antidiabetic peptide hormone amylin that contains proline residues substituted at positions 25, 28, and 29. It stimulates cAMP production in HEK293 cells expressing human amylin receptor 1a (AMY1a), AMY2a, and AMY3a (EC50s = 0.35, 22.9, and 0.89 nM, respectively). Pramlintide inhibits human islet amyloid polypeptide fibrilization in a concentration-dependent manner. In vivo, pramlintide (200 pg/kg) reduces brain levels of amyloid-β (1-40) and increases spontaneous alternation in the Y-maze in the Tg2576 transgenic mouse model of Alzheimer's disease.

Pramlintide acetate, a polypeptide analogue of human amylin, functions as an antidiabetic agent and exhibits antineoplastic activity in colorectal cancer.

Ceftaroline fosamil hydrate acetate is a powerful cephalosporin antibiotic that exhibits broad-spectrum efficacy against both Gram-positive pathogens, such as methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Streptococcus pneumoniae, and common Gram-negative bacteria. It possesses anti-infective properties suitable for studying complicated skin and skin structure infections (cSSSIs) and community-acquired bacterial pneumonia (CABP) [1] [2] [3].

Nafarelin is a gonadotropin-releasing hormone agonist (GnRH agonist) which acts as an analog of GnRH. Nafarelin increases the release of FSH and LH by the anterior pituitary, which in turn leads to an increase of estrogen/progesterone. When administered, Nafarelin has the purpose of causing increase estrogen that will negatively feed back upon hypothalamus to decrease GnRH ( negative feedback loop ) Through negative feedback, Nafarelin causes a decrease in pituitary secretion of gonadotropins luteinizing hormone (LH) and follicle stimulating hormone (FSH). Nafarelin may be used in the treatment of estrogen-dependent conditions (such as endometriosis or uterine fibroids), to treat central precocious puberty, and to control ovarian stimulation in IVF. It is normally delivered via a nasal spray. Nafarelin acetate is marketed by Searle (now part of Pfizer) under the brand name Synarel.
