Disclosed are novel compounds, compositions, and methods that are particularly useful in photodynamic therapy. In particular, the inventive compounds, compositions, and methods relate to the formation of cytotoxic radical species in the presence of light. Significantly, the compounds, compositions, and methods of the present invention do not require the presence of oxygen in the photodynamic therapy and, as such, rely on a unimolecular mechanism for producing the radicals. The inventive compounds, compositions, and methods can be used, for example, in the treatment of cancers as well as infections caused by microorganisms such as protozoa, fungi, bacteria, and viruses.
4,5-Diazafluorene N-glycopyranosyl hydrazones as scaffolds for potential bioactive metallo-organic compounds: Synthesis, structural study and cytotoxic activity
cyclic derivatives, whose structures correspond to N-β-glycopyranosyl hydrazones except for the d-arabinose derivative that agrees with the α-anomer. Several copper(II) complexes having a 2:1 ligand to metal mole ratio were also prepared. The metal complexes can bind DNA sequences and preferentially stabilize G-quadruplex DNA structures over dsDNA. The fucose, rhamnose and deoxyglucose copper(II) complexes
通过用不同的未保护的单糖处理9 H -4,5-二氮杂芴基-9- in,以合成有用的产率制备了一系列新颖的N 1-(4,5-二氮杂芴-9-li基)-N 2-甘氨酰呋喃糖基肼。与测试的单糖的反应可立体选择性地提供环状衍生物,其结构对应于N -β-甘露糖基,除了d-与α-端基异构体一致的阿拉伯糖衍生物。还制备了几种配体与金属的摩尔比为2:1的铜(II)配合物。金属配合物可以结合DNA序列,并且比dsDNA优先稳定G-四链体DNA结构。岩藻糖,鼠李糖和脱氧葡萄糖铜(II)配合物对培养的HeLa和PC3肿瘤细胞显示出与通常用于化学治疗目的的其他金属配合物(如顺铂)相当的细胞毒活性。

di-p-tosylate, and tetraethyleneglycol di-p-tosylate, respectively, have been synthesized. Reaction of Ru(bpy)(2)Cl(2).2H(2)O with BL(1-6), respectively, afforded six bimetallic complexes [(bpy)(2)RuBL(1-6)Ru(bpy)(2)](4+) as PF(6)(-) salts. Cyclic voltammetry of these complexes is consistent with one Ru(II)-centered oxidation around 1.32V and three ligand-centered reductions. These complexes show metal-to-ligand
