  Synthesis and structural characterization of gallium and indium complexes obtained from redistribution reactions of mixed chalcogen-imidodiphosphinate ligands

  摘要：

  The ionic complex [Ga{N(SP'Pr-2)(SeP'Pr-2)-S, Se}(2)](+)[GaCl4](-) (5) was prepared by a ligand redistribution process from the monochelate Cl2Ga{N(SP'Pr-2)(SeP'Pr-2)-S,Se}] (3) complex in benzene. A similar phenomenon was observed for the heavier indium homologues, where the neutral complexes [ClIn{N(SP'Pr-2)(SeP'Pr-2)-S, Se}(2)] (7) and [ClIn{N(OP'Pr-2)(SP'Pr-2)-O, S}(2)] (8) were isolated along with InCl3 as the main reaction by-product. Complexes 5, 7 and 8 were characterized by single-crystal X-ray structural analysis. (c) 2005 Elsevier B.V. All rights reserved.

  Reaction of (Pr2PCl)-Pr-i with (Me3Si)(2)NH gives (Pr2PNHPPr2)-Pr-i-P-i (not isolated) which was oxidised with sulfur/selenium/oxygen to give (Pr2P)-Pr-i(E)NHP(E')Pr-i(2) (E, E'=Se; E=Se, E'=S; E=S, E'=O; E,E'=O). These neutral LH molecules readily undergo deprotonation/complexation to form simple ML, species and demonstrative examples with Zn, Cd, Pd, Pt are reported. The X-ray structure of two examples of (Pr2P)-Pr-i(E)NHP(E')Pr-i(2) (E, E' = Se, E,EI = O) are reported. The molecules pack into infinite chains via H...E Hydrogen bonds. The X-ray structures of three typical metal complexes which illustrate tetrahedral (Cd[((Pr2PSe)-Pr-i)(2)](2)) and square planar (Pt[N((Pr2PSe)-Pr-i)(2)](2)) coordination at the metal centre as well as the ability of the ME2P2N ring to adopt the pseudo-chair conformation (Pt[(Pr2P)-Pr-i(Se)NHP(S)Pr-i(2)](2)) are also reported.

  Postprandial hyperglycemia has orchestrated untimely death among diabetic patients over the decades and regulation of α-amylase activity is now becoming a promising management option for type 2 diabetes. The present study investigated the binding interactions of three structurally diverse dichalcogenoimidodiphosphinate ligands with α-amylase to ascertain the affinity of the ligands for α-amylase using spectroscopic and molecular docking methods. The ligands were characterized using ¹H and ³¹P NMR spectroscopy and CHN analysis. Diselenoimidodiphosphinate ligand (DY300), dithioimidodiphosphinate ligand (DY301), and thioselenoimidodiphosphinate ligand (DY302) quenched the intrinsic fluorescence intensity of α-amylase via a static quenching mechanism with bimolecular quenching constant (Kq) values in the order of x10¹¹ M^-1s^-1, indicating formation of enzyme-ligand complexes. A binding stoichiometry of n≈1 was observed for α-amylase, with high binding constants (Ka). α-Amylase inhibition was as follow: Acarbose > DY301>DY300>DY302. Values of thermodynamic parameters obtained at temperatures investigated (298, 304 and 310 K) revealed spontaneous complex formation (ΔG<0) between the ligands and α-amylase; the main driving forces were hydrophobic interactions (with DY300, DY301, except DY302). UV-visible spectroscopy and Förster resonance energy transfer (FRET) affirmed change in enzyme conformation and binding occurrence. Molecular docking revealed ligands interaction with α-amylase via some key catalytic site amino acid residues (Asp197, Glu233 and Asp300). DY301 perhaps showed highest α-amylase inhibition (IC₅₀, 268.11 ± 0.74 μM) due to its moderately high affinity and composition of two sulphide bonds unlike the others. This study might provide theoretical basis for development of novel α-amylase inhibitors from dichalcogenoimidodiphosphinate ligands for management of postprandial hyperglycemia.
