  Cell permeable probes to image the presence and localization of kinases are important in studying their function and as diagnostic tools. Despite the central role of kinases as therapeutic targets, there are remarkably few probes available. Herein we report the discovery of a probe to image two therapeutically relevant kinases: EGFR and ERBB2. The probe was identified from a library based on a scaffold derived from the resorcyclic acid lactones that form a covalent adduct by reacting specifically with an unconserved cysteine in the nucleotide-binding site of the kinases. We demonstrated the utility of the newly discovered probe by imaging of EGFR localization and ERBB2 inhibition in live cells.

  在研究激酶的功能和将其作为诊断工具时，对激酶的存在和定位进行成像的细胞渗透探针非常重要。尽管激酶作为治疗靶点发挥着核心作用，但可用的探针却少得可怜。在此，我们报告发现了一种探针，可以对两种与治疗相关的激酶进行成像：表皮生长因子受体和 ERBB2。这种探针是从一个文库中发现的，该文库的基础是一种源自间环酸内酯的支架，间环酸内酯通过与激酶核苷酸结合位点中未保留的半胱氨酸发生特异性反应而形成共价加合物。我们通过对活细胞中表皮生长因子受体定位和ERBB2抑制作用的成像，证明了新发现探针的实用性。

  The present teaching provides a fluorescent oligonucleotide probe having a high degree of design flexibility and wide applicability, as well as the use thereof. This is an oligonucleotide probe capable of forming a stem and loop, comprising at least one fluorophore located between adjacent nucleotides in the stem and is linked to a unit represented by Formula (1) and at least one quencher located at a site capable of pairing up with the at least one fluorophore located between the adjacent nucleotides in the stem and is linked to a unit represented by Formula (2). (In the formulae, X represents the fluorophore, Y represents the quencher, R1 represents an optionally substituted C 2 or C 3 alkylene chain, R2 represents an optionally substituted C 0-2 alkylene chain, and Z represents a direct bond or linker.)

  Excitonic interaction was utilized to design a highly sensitive in‐stem molecular beacon (ISMB) in which both a fluorophore and a quencher on D‐threoninols are incorporated as a pseudo base pair (see scheme; optimized combination with Cy3 and modified Methyl Red). Minimization of the difference between λmax of the fluorophore and quencher maximized quenching efficiency.

  Cystic fibrosis transmembrane conductance regulator (CFTR) is a cell-surface anion channel that permeates chloride and bicarbonate ions. The most frequent mutation of CFTR that causes cystic fibrosis is the deletion of phenylalanine at position 508 (Delta F508), which leads to defects in protein folding and cellular trafficking to the plasma membrane. The lack of the cell-surface CFTR results in a reduction in the lifespan due to chronic lung infection with progressive deterioration of lung function. Hsc70 plays a crucial role in degradation of mutant CFTR by the ubiquitin-proteasome system. To date, various Hsc70 inhibitors and transcription regulators have been tested to determine whether they correct the defective activity of mutant CFTR However, they exhibited limited or questionable effects on restoring the chloride channel activity in cystic fibrosis cells. Herein, we show that a small molecule apoptozole (Az) has high cellular potency to promote membrane trafficking of mutant CFTR and its chloride channel activity in cystic fibrosis cells. Results from affinity chromatography and ATPase activity assay indicate that Az inhibits the ATPase activity of Hsc70 by binding to its ATPase domain. In addition, a ligand-directed protein labeling and molecular modeling studies also suggest the binding of Az to an ATPase domain, in particular, an ATP-binding pocket. It is proposed that Az suppresses ubiquitination of Delta F508-CFTR maybe by blocking interaction of the mutant with Hsc70 and CHIP, and, as a consequence, it enhances membrane trafficking of the mutant.

  A new fluorescence-based detection method was developed to visualize zidovudine-incorporated DNA using click chemistry. This bio-orthogonal detection method was used to quantify the relative susceptibility of various DNA-synthesizing enzymes toward ZDV incorporation on the basis of ratiometric analysis of band shifts in the gel and the visual observation of cellular DNA.
