| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

(2E,25E)-11,14,17,33,36,39,42-Hepta-oxa-penta-cyclo-[41.4.0.0.0.0]hepta-tetra-con ta-1(43),2,5(10),6,8,18,20,22,25,27,29,31,44,46-tetra-decaene-4,24-dione.[Pubmed:21754440]
Acta Crystallogr Sect E Struct Rep Online. 2011 May 1;67(Pt 5):o1128-9.
The title compound, C(40)H(40)O(9), is a product of the double crotonic condensation of bis-(2-acetyl-phen-oxy)-3-oxapentane with bis-(2-formyl-phen-oxy)-3,6-dioxaoctane. The title macromolecule includes the 31-crown-7-ether skeletal unit and adopts a saddle-like conformation. The two ethyl-ene fragments have E configurations. The volume of the inter-nal cavity of the macrocycle is approximately 125 A(3). In the crystal, the mol-ecules are arranged at van der Waals distances.
Truncated Orexin Peptides: Structure-Activity Relationship Studies.[Pubmed:24707347]
ACS Med Chem Lett. 2013 Dec 12;4(12):1224-1227.
Orexin receptors are involved in many processes including energy homeostasis, wake/sleep cycle, metabolism and reward. Development of potent and selective ligands is an essential step for defining the mechanism(s) underlying such critical processes. The goal of this study was to further investigate the structure-activity relationships of these peptides and to identify truncated form of the orexin peptides active at OX1. Truncation studies have led to OXA (17-33) as the shortest active peptide known to date with a 23-fold selectivity for OX1 over OX2. Alanine, D-amino acid and proline scans have highlighted the particular importance of Tyr(17), Leu(20), Asn(25) and His(26) for agonist properties of OXA(17-33). The conformation of the C-terminus might also be a defining factor in agonist activity and selectivity of the orexin peptides for the OX1 receptor.
Structure-activity analysis of truncated orexin-A analogues at the orexin-1 receptor.[Pubmed:11266181]
Bioorg Med Chem Lett. 2001 Mar 12;11(5):737-40.
Truncated peptide analogues of orexin-A were prepared and their biological activity assesed at the orexin-1 receptor. Progressive N-terminal deletions identified the minimum C-terminal sequence required for maintaining a significant agonist effect, whilst an alanine scan and other pertinent substitutions identified key side-chain and stereochemical requirements for receptor activation.
