First Diphosphinoamine Ligand Bearing a Polymerizable Side Chain: Complexation with Copper(I)
A diphosphinoamine ligand with a polymerizable side chain, (PPh2)2N CH2 C6H4 CH1⁄4CH2 (vbzpnp or 1), was synthesized. The ligand could be polymerized by anionic polymerization with n-butyllithium as the initiator. Polyvbzpnp was soluble in tetrahydrofuran and chloroform but was insoluble in methanol and was characterized with NMR, IR, and gel permeation chromatography. The numberaverage and wei...
متن کاملSide-chain flexibility in proteins upon ligand binding.
Ligand binding may involve a wide range of structural changes in the receptor protein, from hinge movement of entire domains to small side-chain rearrangements in the binding pocket residues. The analysis of side chain flexibility gives insights valuable to improve docking algorithms and can provide an index of amino-acid side-chain flexibility potentially useful in molecular biology and protei...
متن کاملSynthesis and Solution Complexation Studies of a new Schiff base Ligand
A new Schiff base ligand, 2,2'-{pyridine-2,6-diylbis[nitrilo(E)methylylidene]}bis(4 bromophenol),has been synthesized by reaction of the 2,6-diamino pyridine with 5-bromo salicylaldehyde at ethanolunder refluxing. The structure of the synthesized compound resulted from the IR, 1HNMR, MS andUV spectroscopy and elemental analysis data. Formation Constant (kf) value of it’s complexes withCu2+, Ni2...
متن کاملSide-chain rotamer changes upon ligand binding: common, crucial, correlate with entropy and rearrange hydrogen bonding
MOTIVATION Protein movements form a continuum from large domain rearrangements (including folding and restructuring) to side-chain rotamer changes and small rearrangements. Understanding side-chain flexibility upon binding is important to understand molecular recognition events and predict ligand binding. METHODS In the present work, we developed a well-curated non-redundant dataset of 188 pr...
متن کاملCoordinating a Seller-Buyer Supply Chain with a Proper Allocation of Chain’s Surplus Profit Using a General Side-Payment Contract
In this paper, seller-buyer supply chain coordination with general side-payment contracts is introduced to gain the maximum possible chain profit. In our model, the logistics costs for both buyer and seller are considered and the final demand is also supposed to be a decreasing function of the retail price. Since parties aim to maximize their individual profits, the contractual parameters are s...
