-
Paragraph 0143; 0167-0171, (2019/05/10)
The present invention provides: a novel pyrrolo-lactone compound, which can be used as an improved pain therapeutic agent containing various substituents by using glucose and ribose as reducing sugars and conducting a reaction with various kinds of natural and unnatural amino acids; and novel pyrrolo compounds produced during a process of manufacturing the same. The novel pyrrolo-lactone and pyrrole compounds are substances which can be used as improved pain therapeutic agent by having increased restoration ability of glutathione in living cells against reactive oxygen species.COPYRIGHT KIPO 2019
Histidine–dialkoxyanthracene dyad for selective and sensitive detection of mercury ions
Patil, Sachin,Belhajjame, Widad,Moosa, Basem,Khashab, Niveen M.
, p. 345 - 350 (2017/12/26)
Histidine-dialkoxyanthracene (HDA) was synthesised as a turn off type fluorescent sensor for fast and sensitive detection of mercury ions (Hg2+) in aqueous media. The two histidine moieties act as ‘claws’ to selectively complex Hg2+. The binding ratio of HDA to Hg2+ was 1:1 (metal-to-ligand ratio). The association constant for Hg2+ towards the receptor HDA obtained from Benesi–Hildebrand plot was found to be 3.22?×?104?M?1 with detection limit as low as 4.7?nM (0.94?μg/L).
Exciton-Coupled Circular Dichroism Characterization of Monotopically Binding Guests in Host?Guest Complexes with a Bis(zinc porphyrin) Tweezer
Olsson, Sandra,Sch?fer, Clara,Blom, Magnus,Gogoll, Adolf
, p. 1169 - 1178 (2019/01/04)
A stiff-stilbene-linked bisporphyrin tweezer with inherent helicity was used for exciton-coupled circular dichroism (ECCD) characterization of a series of monotopically binding amine guest molecules. CD signals were observed for a variety of monoamines at relatively low tweezer/amine (host/guest) ratios between 1 : 10 to 1 : 70. For the amines producing the most intense CD signals, a binding stoichiometry of 1 : 2 was found. A likely explanation is the presence of guest-guest interactions in the complexes. This is supported by the correlation observed between CD signal intensity and magnitude of possible noncovalent binding between the guests, which can be divided into three groups showing no, moderate and strong response, respectively. Further support for this rationalization comes from molecular modelling.

Furthermore, processes for their preparation and their use are disclosed.
Structure-stability correlations for imine formation in aqueous solution
Godoy-Alcantar,Yatsimirsky, Anatoly K.,Lehn
, p. 979 - 985 (2007/10/03)
Imine formation between 25 aldehydes and 13 amines in aqueous solution in the pH range 7-11 was studied by 1H NMR spectroscopy. A three-parameter linear equation correlating logarithms of imine formation constants with pKa and HOMO energies of amines and LUMO energies of aldehydes is proposed. In view of the widespread occurrence of imine-forming processes in both chemistry and biology, the data presented are of significance for physical organic chemistry and of particular interest for dynamic combinatorial chemistry.
