Publication number: 20120226048Abstract: The present invention relates to a paramagnetic polynuclear metal complex having enhanced self-relaxation rate and thermodynamic stability, and more particularly, to a synthetic method of a novel DTPA-bis-amide-histidine ligand and DTPA-bis-amide-aspartic acid ligand, a novel gadolinium complex ([Gd(L)H2O]) using the ligand, and a paramagnetic polynuclear metal complex using the gadolinium complex. The paramagnetic polynuclear metal complex is able to fix three or more metals (one gadolinium and two metal ions), thereby providing more excellent self-relaxation rate than the commercially available contrast agents. Thus, it can be widely applied to an MRI contrast agent because of meeting the high self-relaxation rate required as a contrast agent of magnetic resonance imaging (MRI).Type: ApplicationFiled: November 11, 2009Publication date: September 6, 2012Applicant: Kyungpook National University Industry-Academic Cooperation FoundationInventors: Tae Jeong Kim, Yong Min Chang, Hee Kyung Kim

Publication number: 20110312895Abstract: The invention relates to compounds having either agonist or antagonist activities for the neurotrophins NGF and BDNF and represented by monomeric or dimeric substituted dipeptides that are analogs of the exposed portions of loop 1 or loop 4 regions of these neurotrophins near or at a beta-turn of the respective loop. N-acylated substituents of these dipeptides are biostereoisomers of the amino acid residues preceding these dipeptide sequences in the neurotrophin primary structure. The dimeric structure is produced advantageously by using hexamethylenediamine to which dipeptides are attached via their carboxyl groups. The claimed compounds displayed neuroprotective and differentiation-inducing activities in cellular models and enhanced the amount of phosphorylated tyrosine kinase A and the heat shock proteins Hsp32 and Hsp70 in the concentration range of 10?9 to 10?5 M.Type: ApplicationFiled: February 15, 2010Publication date: December 22, 2011Inventors: Sergey Borisovich Seredenin, Tatyana Alexandrovna Gudasheva
