Amplifier-mediated activation of cell-penetrating peptides with steroids: multifunctional anion transporters for fluorogenic cholesterol sensing in eggs and blood

Autor: Sara Marie Butterfield, Stefan Matile, Tomohiro Miyatake

Publikováno v: Angewandte Chemie: International Edition, Vol. 48, No 2 (2009) pp. 325-328

Off-the-shelf, prêt-à-porter multianalyte sensing systems are based on the ability of cell-penetrating peptides (CPPs; see picture, blue) to mediate the export of hydrophilic anions (yellowgreen) from lipid bilayer vesicles (gray). Covalent capture

Chimia, Vol. 62, No 4 (2008) pp. 215-216

Recent experimental evidence confirms synthetic pores as operational multicomponent sensors in complex matrices. This work in practice is summarized, with emphasis on topics of current concern which exemplify the use of enzymes as signal generators i

Fluorometric detection of inositol phosphates and the activity of their enzymes with synthetic pores: discrimination of IP7 and IP6 and phytate sensing in complex matrices

Autor: Sara Marie Butterfield, Duy-Hien Tran, Glenn D. Prestwich, Stefan Matile, Honglu Zhang

Publikováno v: Journal of the American Chemical Society, Vol. 130, No 11 (2008) pp. 3270-3271

We report the fluorometric and noninvasive detection of inositol phosphates, which act as privileged blockers of synthetic pores. Phytate (IP6) and IP7 recognition in the pore occurs substoichiometrically in the low nanomolar range, with more than 2

The objective with synthetic multifunctional nanoarchitecture is to create large suprastructures with interesting functions. For this purpose, lipid bilayer membranes or conducting surfaces have been used as platforms and rigid-rod molecules as shape

Colorful methods to detect ion channels and pores: intravesicular chromogenic probes that respond to pH, pM and covalent capture

Autor: Sara Marie Butterfield, Stefan Matile, Andreas Hennig

Publikováno v: Organic & Biomolecular Chemistry. 7:1784

The activity of synthetic pores, ion channels, transporters and carriers is usually determined with fluorescent probes in vesicles or by conductance measurements in planar lipid bilayers. Elaborating on more colorful alternatives, we here introduce 5
