  Vanadium complexes with different ligands were synthesized and evaluated for antiproliferative activity on U937 cells. The alkyl chain length of the ligands affected the antiproliferative activity, and two complexes—3b and 4—exhibited strong activities with IC50 values of 6.02 and 3.90 μM respectively. Annexin V staining and DNA ladder formation indicated that these complexes induced apoptosis in U937 cells.

  The recent emphasis on understanding the myriad roles of zinc in both normal and diseased cells and tissues has placed an ever increasing demand on methods for sensitive and selective methods for real-time monitoring of free Zn^(2+) in complex biological samples. Chelation-enhanced fluorescent sensors for zinc, based on fluorophores such as quinoline, dansyl, fluorescein, and anthracene, have been

  Photochemical bond-cleavage reactions are potentially useful in chemistry, bioorganic chemistry and medicinal chemistry. We previously reported on a photochemical cleavage reaction of 8-quinolinyl sulfonate (8-QS) derivatives in aqueous solution at neutral pH, which we proposed to proceed via an excited triplet state. In this report, we report on the synthesis of some new photocleavable 8-QS derivatives

  In radiation therapy, adverse side effects are often induced due to the excessive cell death that occurs in radiosensitive normal cells. The radiation-induced cell death of normal cells is caused, at least in part, by apoptosis, which undergoes via activation of p53 and increase in the p53 protein, a zinc-containing transcriptional factor, in response to cellular damage. Therefore, radioprotective drugs that can protect normal cells from radiation and thus suppress adverse side effects would be highly desirable. We report herein on the radioprotective activity of 8-hydroxyquinoline (8HQ) derivatives that were initially designed so as to interact with the Zn2+ in p53. Indeed, the 5,7-bis(methylaminosulfonyl)-8HQ and 8-methoxyquinoline derivatives considerably protected MOLT-4 cells against gamma-ray radiation (10 Gy), accompanied by a low cytotoxicity. However, mechanistic studies revealed that the interaction of these drugs with p53 is weak and the mechanism for inhibiting apoptosis appears to be different from that of previously reported radioprotectors such as bispicen, which inhibits apoptosis via the denaturation of p53 as well as by blocking both transcription-dependent and -independent apoptotic pathways.

• Modular and Tunable Chemosensor Scaffold for Divalent Zinc
  作者：Melissa D. Shults、Dierdre A. Pearce、Barbara Imperiali

  DOI：10.1021/ja0355980

  日期：2003.9.1

  A modular peptide scaffold has been developed for fluorescent sensing of divalent zinc. The signaling component of the chemosensor is the chelation -sensitive fluorophore 8-hydroxy-5-(N,N-dimethylsulfonamido)-2-methylquinoline, which is prepared as the protected amino acid derivative Fmoc-Sox-OH and integrated into peptide sequences. Nineteen synthetic peptides incorporating the signaling element exhibit a range of affinities for Zn2+ through variation of the type and number of Zn2+ ligands, ligand arrangement and the beta-turn sequence that acts as a preorganization element between the ligands. The stoichiometry of the peptide-Zn2+ complexes is evaluated by several criteria. The fluorescence response of these peptides to pH and various important metal ions is reported. Eleven of these sequences form only 1:1 complexes with Zn2+ and their affinities range from 10 nM to nearly 1 muM. When used in concert, these sensors can provide Zn2+ concentration information in a valuable range.
