Research paper thumbnail of Intracellular flow cytometric lipid analysis – a multiparametric system to assess distinct lipid classes in live cells

Current methods for analysing lipid components of cells are technically challenging and destructive. Here, we report a facile, inexpensive method to identify lipid content – intracellular flow cytometric lipid analysis (IFCLA). Distinct lipid classes can be distinguished by Nile Blue fluorescence, Nile Red fluorescence or violet autofluorescence. Nile Blue is fluorescent in the presence of unsaturated fatty acids with a carbon chain length greater than 16. Cis-configured fatty acids induce greater Nile Blue fluorescence than their trans-configured counterparts. In contrast, Nile Red exhibits greatest fluorescence in the presence of cholesterol, cholesteryl esters, some triglycerides and phospholipids. Multiparametric spanning-tree progression analysis for density-normalized events (SPADE) analysis of hepatic cellular lipid distribution, including vitamin A autofluorescence, is presented. This flow cytometric syst...

Research paper thumbnail of Expanding the breadth of 4-amino-1,8-naphthalimide photophysical properties through substitution of the naphthalimide core

At the centre of this technology lies the fluorescent reporter molecule, and it is therefore crucial to provide a breadth of fluorophores with varying photophysical and biological behaviour. 4-Amino-1,8-naphthalimides are commonly employed in fluorescent sensors, but the narrow range of structural derivatives limits versatility of application. Here we report the synthesis and investigation of a set of twelve 4-amino-1,8-naphthalimides bearing an additional substituent on the aromatic core. Photophysical characterisation and Time-Dependent Density Functional Theory studies provided insights into the structure-photophysical property relationships of these derivatives, which show an expanded range of emission wavelengths and other photophysical properties. These compounds could all be visualised within cells by confocal microscopy, showing cyto...

Research paper thumbnail of Selective Solvent Extraction of Silver(I) by Tris-Pyridyl Tripodal Ligands and X-Ray Structure of a Silver(I) Coordination Polymer Incorporating One Such Ligand

Competitive seven-metal extraction studies (H2O/CHCl3) incorporating equal concentrations of cobalt(ii), nickel(ii), copper(ii), zinc(ii), silver(i), cadmium(ii), and lead(ii) in the aqueous phase and L1 or L2 in the organic phase showed selective extraction of silver(i) in each case. A parallel solvent extraction experiment involving a related tripodal tris-pyridyl ligand (L3) based on a 1,3,5-substituted aryl ring scaffold and incorporating thioether sulfurs in each tripod arm also showed extraction selectivity for silver(i); extraction efficiencies towards this metal ion fall in the order L3 > L1 > L2. Physical data are in accord with L1 forming a capsule-like complex of type [Ag3L12]3+ in which silver ions link pairs of pyridyl groups from different ligands. In contrast, L2 yields a complex of type [Ag2L2(NO...

We then determined the MICs and minimum fungicidal concentrations (MFCs) of four of the most active compounds (compounds 1, 4, 5, and 8) against 80 Candida and 20 cryptococcal isolates, in comparison with the MICs of amphotericin B, fluconazole, itraconazole, voriconazole, posaconazole, and caspofungin, using Clinical Laboratory and Standards Institutes broth microdulition M27-A3 (yeasts) or M38-A2 (filamentous fungi) susceptibility protocols. The compounds were more potent against Candida and Cryptococcus spp. (MIC range, 0.74 to 27.9 μg/ml) than molds (0.74 to 59.7 μg/ml). MICs against Exophiala were 0.37 to 5.9 μg/ml and as low as 1.48 μg/ml for Scedosporium but ≥25 μg/ml for zygomycetes, Aspergillus , and Fusarium spp. Compounds 1, 4, 5, and 8 exhibited good fungicidal activity against Candida and Cryptococcus , except for Candida parapsilosis (MICs ...

Geometric mean MICs of TRB, BTF, ITC, MI, PYR, and AM were 0.039, 0.059, 1.718, 0.671, 6.006, and 4.771 μg/ml, respectively. MI was more active than ITC ( P < 0.001).

The interaction with the Ag ions-which, for example, can be complexed by two phenyl groups in a sandwich-type manner (see drawing on the right)-provides positively charged assemblies in a nondestructive way.
