Carcinine (: Carcinine (.beta.-alanyl-histamine): rapid synthesis, blood pressure effects upon vertebrates. Arnould, J. M.; Frentz, R. (Lab. Biol. Anim. II, Univ. Nancy I, Nancy, Fr.). Arch. Int. Physiol. Biochim., 85(2), 339-50 (French) 1977. CODEN: AIPBAY. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacodynamics) Carcinine [56897-53-1] was synthesized by direct condensation of t-butoxycarbonyl .beta.-alanine [3303-84-2] with histamine [51-45-6]. Carcinine (3-4 mg/kg) had a vasodepressive action on rabbits but had little effect on heart rate or respiration rate in the rat. To obtain the same effects as histamine [51-45-6], 1000-fold higher concn. of carcinine was necessary.

Journal of Structural Chemistry (Translation of Zhurnal Strukturnoi Khimii), 44(5), 790-795 (English) 2003 Kluwer Academic/Consultants Bureau. CODEN: JSTCAM. ISSN: 0022-4766. DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) Section cross-reference(s): 22 A terminally blocked tripeptide Boc-b-Ala-Aib-b-Ala-OMe (1) (Aib = aminoisobutyric acid) with non-coded amino acids forms a novel type of hairpin structure contg. a g-turn instead of a conventional b-turn in the central loop region in soln. This new type structural motif was characterized by NMR and restraint mol. dynamics simulation study. In the solid state peptide 1 adopts an extended backbone conformation and self-assembles to form supramol. b-sheet.Except for chemicals metioned above, 380375-78-0 and 3303-84-2 are also used. .
