A successful synthesis of O-sulfated syndecan-1-like (Q23-E120) glyco-polypeptide was accomplished. The synthesis features the integration of an O-sulfated carbohydrate-bearing glycopeptide cassette with efficient protein ligation strategies, overcoming the acid lability of carbohydrate sulfates as a major hurdle in solid-phase peptide synthesis. Crucial to the synthesis is the microwave-assisted Ag(I) ligation, which afforded the ligation product in improved overall yield. This O-sulfated syndecan-1 (Q23-E120) is the longest O-sulfated glyco-polypeptide prepared to date.

Structure and spectral properties of dinuclear zinc complex containing semicarbazonate ligands

The dinuclear Zn2+ complex [Zn(HSSC)OAc]2·2DMF (H2SSC = salicylaldehyde semicarbazone; HOAc = acetic acid; DMF = N,N-dimethylfomamide) was prepared and structurally characterized by single crystal X-ray. The basic structural unit of the complex is a dinuclear complex [Zn(HSSC)OAc]2 in which the semicarbazone ligand adopts the phenol-imine form. The deprotonated phenol group forms a one-atom bridge between the two zinc centers, and both of the zinc centers are five-coordinated. The local coordination environment of Zn2+ can be approximately considered as square pyramidal. UV spectral studies show that the H 2SSC provides strong binding of Zn2+ in a 1:1 ratio in solution. The conditional binding constant of the complex is lg KZn-L = 12.89 ± 0.76 in 0.05 M Tris-HCl buffer at pH 7.4. The H2SSC exhibits an enhanced fluorescence effect by the addition of Zn2+, and affords an excellent selectivity for Zn2+ under physiological conditions.

Manganese(ii) complex of an oxygen-nitrogen donor Schiff base ligand showing efficient catechol oxidase activity: Synthesis, spectroscopic and kinetic study

, p. 3748 - 3754 (2020/03/17)
Tridentate O,N,O-donor Schiff base ligand (E)-1-(2-hydroxybenzylidene)semicarbazide (H2L1) and its Mn(ii) complex have been synthesized. Both the ligand and the complex have been characterized by analytical and spectroscopic techniques. X-ray crystal structure determination of the Mn(ii) complex shows that the Mn(ii) atom is in a distorted octahedral environment and there are two crystallographically different manganese atoms in the unit cell. The Mn(ii) complex shows very high catalytic activity for catechol oxidation (kcat = 3.10 × 106 h-1, kcat/KM = 3.25 × 108 h-1 M-1), which is the highest catalytic efficiency for catechol oxidation by a manganese complex reported in the literature. The probable mechanism of the catalytic reaction is explored using ESI-MS and EPR spectroscopy.
