Non-fused Phospholes as Fluorescent Probes for Imaging of Lipid Droplets in Living Cells
Molecular tools for fluorescent imaging of specific compartments in cells are essential for understanding the function and activity of cells. Here, we report the synthesis of a series of pyridyl- and thienyl-substituted phospholes and the evaluation of these dyes for fluorescent imaging of cells. The thienyl-substituted phospholes proved to be successful for staining of cultured normal and mali...
متن کاملCarbaborane-based alkynylphosphanes and phospholes.
The reaction of 1,2-bis(N,N-dimethylaminochloro-phosphanyl)-1,2-dicarba-closo-dodecaborane(12) and lithiated phenylacetylene gives a five-membered dihydrophosphole derivative with an exocyclic phosphanyl group. This unexpected reaction opens new possibilities for the synthesis of carbaborane-containing phosphorus heterocycles. P,P'-alkynylated 1,2-bis(phosphanyl)-1,2-dicarba-closo-dodecaborane(...
متن کاملPhosphorus Centers of Different Hybridization in Phosphaalkene-Substituted Phospholes
Phosphole-substituted phosphaalkenes (PPAs) of the general formula Mes*P=C(CH(3))-(C(4)H(2)P(Ph))-R 5 a-c (Mes*=2,4,6-tBu(3)Ph; R=2-pyridyl (a), 2-thienyl (b), phenyl (c)) have been prepared from octa-1,7-diyne-substituted phosphaalkenes by utilizing the Fagan-Nugent route. The presence of two differently hybridized phosphorus centers (σ(2) ,λ(3) and σ(3) ,λ(3)) in 5 offers the possibility to s...
متن کاملESI MS/MS Study of Calix4arene Derivatives and their Metal Complexes
The peptidocalixarenes 1–3 bearing tryptophan, phenylglycine and leucil units at the lower rim and their complexes with alkali-metal (Li, Na, K, Rb, Cs) and selected lanthanide cations (La, Ce, Eu, Yb) were analyzed by ESI MS. The influences of the solvent (acetonitrile, methanol, addition of formic acid or sodium acetate) and the calixarene:cation molar ratio on signal intensities were investi...
متن کاملFloating Point Fused Add-Subtract and Fused Dot-Product Units
A single precision floating-point fused add-subtract unit and fused dot-product unit is presented that performs simultaneous floating-point add and multiplication operations. It takes to perform a major part of single addition, subtraction and dot-product using parallel implementation. This unit uses the IEEE-754 single-precision format and supports all rounding modes. The fused add-subtract un...
