Peschke, Bernd; Ankersen, Michael; Hansen, Birgit Sehested; Hansen, Thomas Kruse; Johansen, Nils Langeland; Lau, Jesper; Madsen, Kjeld; Petersen, Hans; Thogersen, Henning; Watson, Brett published the artcile< Synthesis and in vitro characterization of new growth hormone secretagogues derived from ipamorelin with dipeptidomimetic N-terminals>, HPLC of Formula: 149518-50-3, the main research area is ipamorelin N terminal dipeptidomimetic derivative preparation; peptidomimetic derivative N terminal ipamorelin growth hormone secretagogue property; structure effect growth hormone secretagogue property peptidomimetic ipamorelin.

The structural requirements for N-terminal features for the minimal structure of growth hormone secretagogues derived from ipamorelin are investigated. It is found, that incorporation of nonpolar peptidomimetic amino acids at the N-terminal can replace the Aib-His moiety and lead to compounds with high in vitro potency with respect to their growth hormone secretagogue properties. New unnatural amino acids with double bonds, ether-linkages, and 1,3-phenylene-moieties in the backbone proved to be valuable dipeptidomimetics. Using them, growth hormone secretagogues with high potencies were obtained.

Leighty, Matthew W.; Georg, Gunda I. published the artcile< Total Syntheses and Cytotoxicity of (R)- and (S)-Boehmeriasin A>, Related Products of 149518-50-3, the main research area is boehmeriasin A alkaloid enantioselective synthesis anticancer cytotoxicity.

Both enantiomers of boehmeriasin A were synthesized in seven steps each using a chiral pool approach. Key steps in the syntheses were a one-flask, two-step protocol to generate the quinolizine core and a C-H functionalization reaction between tetrahydroquinolizinones and an aryltrifluoroborate. The natural product (R)-boehmeriasin A (I) demonstrated potent cytotoxicity against several cancer cell lines, whereas the unnatural (+)-(S)-isomer was significantly less potent.

Gross, Kathleen M. Bertini; Beak, Peter published the artcile< Complex-Induced Proximity Effects: The Effect of Varying Directing-Group Orientation on Carbamate-Directed Lithiation Reactions>, Recommanded Product: 1-Boc-2-Piperidineacetic acid, the main research area is proximity effect complex induced; carbamate directed lithiation.

A series of selected bicyclic carbamates in which the range of accessible angles and distances between the carbonyl group and the proton removed in an α-lithiation reaction are structurally defined have been investigated. Oxazolidinones I (n = 1, 2; R = i-Pr, t-Bu) undergo stereoselective lithiation-substitution reactions to provide cis-II as the major diastereomers. Two series of competition experiments show that the conformationally restricted carbamates undergo lithiation via complexes more efficiently than Boc amines (e.g., N-Boc-pyrrolidine, N-Boc-piperidine). These results along with semiempirical calculations suggest that a small dihedral angle and a calculated distance of 2.78 Å between the carbamate carbonyl oxygen and the proton to be removed are favorable for a carbamate-directed lithiation. A series of tin-lithium exchange experiments indicate that the configurational stability of a carbamate-stabilized organolithium species may be enhanced by restrictive geometry.
