  Selective Zinc Sensor Molecules with Various Affinities for Zn²⁺, Revealing Dynamics and Regional Distribution of Synaptically Released Zn²⁺ in Hippocampal Slices

  摘要：

  We have developed a series of fluorescent Zn2+ sensor molecules with distinct affinities for Zn2+, because biological Zn2+ concentrations vary over a wide range from sub-nanomolar to millimolar. The new sensors have Kd values in the range of 10(-8)-10(-4) M, compared with 2.7 nM for ZnAF-2. They do not fluoresce in the presence of other biologically important metal ions such as calcium or magnesium, and they can detect Zn2+ within 100 ms. In cultured cells, the fluorescence intensity of ZnAF-2 was saturated at low Zn2+ concentration, while that of ZnAF-3 (K-d = 0.79 mu M) was not saturated even at relatively high Zn2+ concentrations. In hippocampal slices, we measured synaptic release of Zn2+ in response to high-potassium-induced depolarization. ZnAF-2 showed similar levels of fluorescence increase in dentate gyrus (DG), CA3 and CA1, which were indistinguishable. However, ZnAF-3 showed a fluorescence increase only in DG. Thus, by using a combination of sensor molecules, it was demonstrated for the first time that a higher Zn2+ concentration is released in DG than in CA3 or CA1 and that we can easily visualize Zn2+ concentration over a wide range. We believe that the use of various combinations of ZnAF family members will offer unprecedented versatility for fluorescence-microscopic imaging of Zn2+ in biological applications.

  completely diminished the antibacterial activity of the known sulfa drug tested, sulfamethoxazole. The sulfa-resistant MRSA strain COL also showed great susceptibility to these desamino-benzenesulfonamides. These results imply a unique mechanism of growth inhibition by these potent desamino-benzenesulfonamides, different from the well-known folate pathway target of sulfonamide antibiotics.

  growing biology, we report a first-generation ratiometric fluorescence resonance energy transfer (FRET) copper probe, FCP-1, for activity-based sensing of labile Cu(I) pools in live cells. FCP-1 links fluorescein and rhodamine dyes through a Tris[(2-pyridyl)methyl]amine bridge. Bioinspired Cu(I)-induced oxidative cleavage decreases FRET between fluorescein donor and rhodamine acceptor.

• Acyl derivatives of p-aminosulfonamides and dapsone as new inhibitors of the arginine methyltransferase hPRMT1

  Arginine methylation is an epigenetic modification that receives increasing interest as it plays an important role in several diseases. This is especially true for hormone-dependent cancer, seeing that histone methylation by arginine methyltransferase I (PRMT1) is involved in the activation of sexual hormone receptors. Therefore, PRMT inhibitors are potential drugs and interesting tools for cell biology. A dapsone derivative called allantodapsone previously identified by our group served as a lead structure for inhibitor synthesis. Acylated derivatives of p-aminobenzenesulfonamides and the antilepra drug dapsone were identified as new inhibitors of PRMT1 by in vitro testing. The bis-chloroacetyl amide of dapsone selectively inhibited human PRMT1 in the low micromolar region and was selective for PRMT1 as compared to the arginine methyltransferase CARM1 and the lysine methyltransferase Set7/9. It showed anticancer activity on MCF7a and LNCaP cells and blocked androgen dependent transcription specifically in a reporter gene system. Likewise, a transcriptional block was also demonstrated in LNCaP cells using quantitative RT-PCR on the mRNA of androgen dependent genes. (C) 2011 Elsevier Ltd. All rights reserved.
