Neuromedin U (NMU) is a neuropeptide first demonstrated to drive smooth muscle contraction.1Translated as a 174 amino acid propeptide, NMU is cleaved to different lengths in different animals. It has diverse receptor-mediated rolesin vivo, as it regulates feeding, vasoconstriction, nociception, and bone remodeling and contributes to obesity, cancer and septic shock.2,2NMU-25 is the active form of NMU in humans. It binds with high affinity to receptors on human left ventricle and coronary artery (KDs = 0.26 and 0.11 nM, respectively), eliciting endothelium-independent vasoconstriction.3NMU-25 also suppresses glucose-stimulated insulin secretion in human islets, and this effect is lost in NMU R165W mutants, resulting in early-onset obesity.4 1.Mitchell, J.D., Maguire, J.J., and Davenport, A.P.Emerging pharmacology and physiology of neuromedin U and the structurally related peptide neuromedin SBritish Journal of Pharmacology15887-103(2009) 2.Greenwood, H.C., Bloom, S.R., and Murphy, K.G.Peptides and their potential role in the treatment of diabetes and obesityRev.Diabet.Stud.8(3)355-368(2011) 3.Mitchell, J.D., Maguire, J.J., Kuc, R.E., et al.Expression and vasoconstrictor function of anorexigenic peptides neuromedin U-25 and S in the human cardiovascular systemCardiovascular Research81353-361(2009) 4.Alfa, R.W., Park, S., Skelly, K.R., et al.Suppression of insulin production and secretion by a decretin hormoneCell Metabolism21(2)323-333(2015)

Jacaric acid is a conjugated polyunsaturated fatty acid first isolated from seeds of Jacaranda plants. Structurally, it is an 18-carbon ω-6 triene isomer of γ-linolenic acid . Jacaric acid induces cell cycle arrest and apoptosis in a variety of cancer cell lines (GI50 = 1-5 μM). It increases the production of reactive oxygen species, and cytotoxicity is abolished by the antioxidant α-tocopherol, suggesting that apoptosis results from oxidative stress. Jacaric acid is metabolized in vivo to conjugated linoleic acid , which is also cytotoxic to cancer cells. Jacaric acid inhibits cyclooxygenase-1 in vitro (Ki = 1.7 μM) and, with long term feeding, decreases stearoyl-CoA desaturase expression and activity in mice.

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are newly identified endogenous lipids regulated by fasting and high-fat feeding and associated with insulin sensitivity. Structurally, these esters are comprised of a C-16 or C-18 fatty acid (e.g., palmitoleic, palmitic, oleic, or stearic acid) linked to either a C-16 or C-18 hydroxy substituent. 12-PAHSA is a FAHFA in which palmitic acid is esterified at the 12th carbon of hydroxy stearic acid. Among the FAHFA family members, PAHSAs are the most abundant in the adipose tissue of glucose tolerant AG4OX mice, which overexpress the Glut4 glucose transporter specifically in adipose tissue. 12-PAHSA is present at 2- to 3-fold higher levels in adipose tissue of AG4OX mice compared to wild type mice. Levels of 12-PAHSA are also higher in fasted wild-type mice compared to fed mice and are reduced upon high-fat diet-induced obesity in insulin-resistant mice.

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are newly identified endogenous lipids regulated by fasting and high-fat feeding and associated with insulin sensitivity. Structurally, these esters are comprised of a C-16 or C-18 fatty acid (e.g., palmitoleic, palmitic, oleic, or stearic acid) linked to a hydroxylated C-16 or C-18 lipid. 9-PAHSA is a FAHFA in which palmitic acid is esterified to 9-hydroxy stearic acid. PAHSAs are the most abundant forms of FAHFA in serum as well as white and brown adipose tissues of glucose tolerant AG4OX mice, which overexpress Glut4 specifically in adipose tissue. 9-PAHSA is the predominant isomer of PAHSA in wild type and AG4OX mice. It is found in humans and is reduced in the serum and adipose tissues of insulin-resistant humans. 9-PAHSA improves glucose tolerance, stimulates insulin secretion, and has anti-inflammatory effects in mice.

Galanin is a neuropeptide with diverse biological activities. [1][2][3][4][5] It binds to rat galanin (GAL) receptor subtypes GAL1-3 (IC50s = 0.339, 1.35, and 3.31 nM, respectively) and human GAL1-3 (IC50s = 0.288, 1.62, and 12.3 nM, respectively). [1] Galanin binds to and inhibits contraction of guinea pig gastric smooth muscle cells induced by carbachol . [2] In vivo, Galanin (6 nmol, i.c.v.) increases feeding behavior in rats and increases latency to hindpaw withdrawal in response to heat and mechanical stimulation in a rat model of carrageenin-induced inflammation when administered at a dose of 2 nmol injected into the nucleus accumbens.[3][4] Galanin (5 μg, i.c.v.) also inhibits acetylcholine release induced by scopolamine in the ventral hippocampus of freely moving rats.
