Synthesis and evaluation of 1,2-trans alkyl galactofuranoside mimetics as mycobacteriostatic agents

The simple octyl β-d-galactofuranoside was previously described as a good bacteriostatic agent against Mycobacterium smegmatis, a non-pathogenic model of M. tuberculosis. In order to decipher its mechanism of action, STD NMR on whole M. smegmatis cells wa

Lithium selective ionophores based on pendant arm substituted crown ethers

Ligands have been synthesised which offer good selectivity for lithium ions over sodium based on substituted 14-crown-4 derivatives which bear diamide groups on the ethylene chain or, less effectively, on the central carbon of the propylene chain.The behaviour of potentiometric membrane electrodes based on these ionophores is compared.

Synthesis of Functionalised 12-,13- and 14-Membered Crown Ethers Bearing Exocyclic Polymerisable Groups and the Binding Properties and Conductivities of their Lithium Doped Polymers

The synthesis of a series of , and -membered crown ethers bearing an exocyclic polymerisable methacrylate is reported.The spacing group between the ring and the methacrylate is either a simple alkyl chain, or 6, or an oxydiethylene chain.The relative binding ability of the "mono and di-substituted" macrocyclic rings towards Li+ is compared by 13C NMR analysis.Radical polymerisation gives the amorphous polymers in which the glass transition temperature is primarily controlled by the nature of the spacer group.In the lithium doped polymers, for a given glass transition temperature, Tg, the -ring materials show enhanced ionic conductivities over the -ring analogues which may be related to the lower rate of lithium exchange (in the former series) or to an enhanced tendency of the -ring systems to form 2:1 complexes with more effective counterion separation.

NITROGEN-CONTAINING TRIPODAL PHOSPHINE LIGANDS

Two tripodal phosphine ligands, 2,2-bis(diphenylphosphinomethyl)-1-(diethylamino)propane (P2N) and 2,2-bis(diethylaminomethyl)-1-diphenylphosphinopropane (PN2) were synthesized.Palladium(II) and Platinum(II) complexes with these ligands were obtained from the reaction of PdCl2(CH3CN)2 and K2PtCl4, respectively.Complex (P2N)PtCl2 crystallizes in space group Pca21 with a = 21.983(5), b = 11.419(1), c = 14.179(3) Angstroem, and the structure was refined to R = 0.039 by using 2826 reflections. Key words: Tripodal ligands; phosphines; nitrogen donors; hybrid donors; complexes.

Molecular Desidn of Crown Ethers. 4. Syntheses and Selective Cation Binding of 16-Crown-5 and 19-Crown-6 Lariats

A number of new lariat 16-crown-5 and 19-crown-6 ethers posesing a variety of single or double side arm(s) were synthesized, and their cation-binding abilities were evaluated by solvent extraction technique.In general, the extractabilities of the 16-crown-5 lariats for most mono- and divalent cations increased gradually with extending oxyethylene side arm.However, sodium and silver ions, which are best size fitted to the crown cavity, showed peac extractability/selectivity at a specific length of the donating side arm.The complexation stoichiometry is 1 : 1 forall cations employed as confirmed by measurement of the extraction equilibrium constants for the single-armed 16-crown-5 (3p).The tetrasubstituted pivot carbon is shown to be a reguirement for lariat 16-crown-5 to effect extra side-arm ligation, although the second side arm of lariat ether 3e seems ineffective in extractability enhancement with reference to the single-armed analogue 3p.By contrast, the corresponding 19-crown-5 lariat with potential donor side arms at an appropiate position did not show any enhancement in extractability for most cations, which may be attributed to its flexible framework.

Neutral Ligands with Surfactant-Type Structure - Synthesis, Complexation, and Ion Transfer

New lipophilic neutral ligands which combine crown ether and podand characteristics with structural features of surfactants (cf. formulas 1-12, 16-26) were synthesized.Their complexation behaviour was studied, their solid-to-liquid and liquid-to-liquid phase transfer properties as well as their efficiency in ion transport across a liquid model membrane.Crystalline stoichiometric complexes of the cycles 2a-4a and of 3e with NaSCN, Ba(SCN)2, and BaI2 can be isolated.Among the noncyclic representatives a crystalline complex is obtained only from 11 with BaI2.The ligand 8d behaves in aqueous solution as a typical surfactant showing micelle formation and cloud point.
