Selective apoptotic killing of malignant hemopoietic cells by antibody-targeted delivery of an amphipathic peptide (2005)

Marks, A.J., Cooper, M.S., Anderson, R.J., Orchard, K.H., Hale, G., North, J.M., ...

The helical amphipathic peptide D-(KLAKLAK)2 is toxic to eukaryotic cells if internalized by a suitable targeting mechanism. We have targeted this peptide to malignant hemopoietic cells via...

Selective apoptotic killing of malignant hemopoietic cells by antibody-targeted delivery of an amphipathic peptide (2005)

Marks, A.J., Cooper, M.S., Anderson, R.J., Orchard, K.H., Hale, G., North, J.M., ...

The alpha-helical amphipathic peptide D-(KLAKLAK)2 is toxic to eukaryotic cells if internalized by a suitable targeting mechanism. We have targeted this peptide to malignant hemopoietic cells via...

Symmetry of Magnetic Quantum Tunneling in the Single-Molecule Magnet Mn12-Acetate (2004)

Del Barco, E., Kent, A. D., Hill, S., North, J. M., Dalal, N. S., Rumberger, E. M., ...

The symmetry of magnetic quantum tunneling (MQT) in the single molecule magnet Mn12-acetate has been determined by sensitive low-temperature magnetic measurements in the pure quantum tunneling regime...

Geldanamycin and herbimycin A induce apoptotic killing of B chronic lymphocytic leukemia cells and augment the cells' sensitivity to cytotoxic drugs (2004)

Jones, D.T., Addison, E., North, J.M., Lowdell, M.W., Hoffbrand, A.V., Mehta, A.B., ...

We studied the actions of geldanamycin (GA) and herbimycin A (HMA), inhibitors of the chaperone proteins Hsp90 and GRP94, on B chronic lymphocytic leukemia (CLL) cells in vitro. Both drugs induced...

Discrete easy-axis tilting in Mn12-acetate, as determined by EPR: implications for the magnetic quantum tunneling mechanism (2004)

Hill, S., Takahashi, S., Edwards, R. S., North, J. M., Dalal, N. S.

The variation with microwave frequency and temperature of previously reported anomalous peaks in the EPR spectra of Mn12-acetate, under large transverse fields, reveals that the molecular easy...

Characterization of the S = 9 excited state in Fe8Br8 by Electron Paramagnetic Resonance (2003)

Zipse, D., North, J. M., Dalal, N. S., Hill, S., Edwards, R. S.

High Frequency electron paramagnetic resonance has been used to observe the magnetic dipole, $\Delta$ M$_s$ = $\pm$ 1, transitions in the $S = 9$ excited state of the single molecule magnet...

Evidence for a very low-lying S = 9 excited state of the S = 10 single molecule magnet Mn12-acetate (2003)

Edwards, R. S., Hill, S., Maccagnano, S., North, J. M., Dalal, N. S.

We present a detailed investigation of the temperature and frequency dependence of the anomalous EPR transitions first observed in Mn12-acetate by Hill et al. [Phys. Rev. Lett. 80, 2453 (1998)]. The...

Definitive spectroscopic determination of the transverse interactions responsible for the magnetic quantum tunneling in Mn12-acetate (2003)

Hill, S., Edwards, R. S., Jones, S. I., North, J. M., Dalal, N. S.

We present detailed angle-dependent single crystal electron paramagnetic resonance (EPR) data for field rotations in the hard plane of the S=10 single molecule magnet Mn12-acetate. A clear four-fold...

Semiconductive and Photoconductive Properties of the Single Molecule Magnets Mn12-Acetate and Fe8Br8 (2003)

North, J. M., Zipse, D., Dalal, N. S., Choi, E. S., Jobiliong, E., Brooks, J. S., ...

Resistivity measurements are reported for single crystals of Mn12-Acetate and Fe8Br8. Both materials exhibit a semiconductor-like, thermally activated behavior over the 200-300 K range. The...

Single Crystal High Frequency Cavity-based EPR Spectroscopy of Single Molecule Magnets (2003)

Hill, S., Edwards, R. S., Jones, S. I., North, J. M., Aliaga, N.

We report high frequency electron paramagnetic resonance (EPR) investigations of a series of high spin (total spin up to S = 10) manganese and nickel complexes which have been shown to exhibit single...
