Herein, a novel soluble mitochondria-targeted theranostic compound, HMX-1, was presented, which was selectively activated under hypoxia with excellent mitochondria-targeting ability at the cellular level, accompanied by a dramatic increase in the fluorescence intensity. Moreover, its anti-cancer efficiency was certified both in vitro and in vivo.

Histone deacetylases (HDACs) play a pivotal role not only in gene expression but also in DNA repair. Herein, we report the successful design, synthesis and evaluation of a chlorambucil derivative named vorambucil with a hydroxamic acid tail as a DNA/HDAC dual-targeting inhibitor. Vorambucil obtained both potent DNA and HDACs inhibitory activities. Molecular docking results supported the initial pharmacophoric hypothesis and rationalized the potent inhibitory activity of vorambucil against HDAC1, HDAC2 and HDAC6. Vorambucil showed potent antiproliferative activity against all the test four cancer cell lines with IC50 values of as low as 3.2–6.2 μM and exhibited 5.0–18.3-fold enhanced antiproliferative activity than chlorambucil. Vorambucil also significantly inhibits colony formation of A375 cancer cells. Further investigation showed that vorambucil remarkably induced apoptosis and arrested the cell cycle of A375 cells at G2/M phase. Vorambucil could be a promising candidate and a useful tool to elucidate the role of those DNA/HDAC dual-targeting inhibitors for cancer therapy.

, p. 771 - 777 (2004)
Two novel DNA-direct alkylating agents, consisting of aniline mustard linked to an angular 3H-pyrrolo[3,2-f]quinoline nucleus, were synthetized and assayed for their in vitro antiproliferative activity. Simple convergent synthesis, consisting of separate preparation of 9-chloro-3H-pyrrolo[3,2-f] quinoline and p-amino-aniline derivatives, and following their linkage by substitution reactions 8a, b and 10, yielded the corresponding diol derivatives 7b and 9. Biological properties were evaluated with respect to cell growth inhibition, ability to form cross-links with DNA, and capacity to give rise to a molecular complex with the macromolecule for 7b, 8b, 9 and 10.
Host-guest interactions involving cyclodextrins: useful complementary insights achieved by polarimetry

A commercial cyanine dye IR-780 and a thioether-containing dicarboxylic acid ligand were used to construct the near-infrared fluorescent probe, which was used as a near-infrared fluorescent indicator for the determination of mercury ions in water and in living cells. This indicator displayed high specificity towards Hg2+ without any interference from other detecting species. Especially, the emission at 790 nm dramatically increased more than 25 times after interacting with Hg2+. The binding experiment showed that the indicator formed 1:1 complex with Hg2+. More, this indicator could be applied in the visualization of Hg2+ in living cells and measuring the Hg2+ concentration of tap-water sample.

The invention discloses a structural formula of a nitrogen mustard derivative N,N-di(2-chloroethyl)-N'-hexadecanoyl-1,4-phenylenediamine, and a preparation method thereof. The preparation method comprises the following steps: preparing N,N-di(2-chloroethyl)-1,4-phenylenediamine; putting the reaction raw materials comprising the N,N-di(2-chloroethyl)-1,4-phenylenediamine, dichloromethane and triethylamine into a reactor, cooling in ice-water bath, stirring, dropwise adding a mixed solution of hexadecanoyl chloride and dichloromethane into the reactor, removing the ice-water bath after addition, conducting reaction at room temperature for 12 to 14 hours, sequentially performing washing, drying and normal-pressure distillation on the reaction liquid after the reaction is conducted completely, and purifying the distilled filter cake to obtain the product. The arylamine nitrogen mustard derivative provided by the invention can effectively reduce the toxic and side effects of nitrogen mustard on the premise of enhancing the treatment index of the nitrogen mustard, and has sterilization and inflammation-diminishing curative effects to reduce the risk of complication caused by the fact that the immunity is reduced after a patient is subjected to chemical therapy.

A new fluorescent sensor based on the BODIPY fluorophore and the carboxyl-thiol metal bonding receptor for Hg2+ was designed and synthesized. The sensor is highly selective for Hg2+ (about 630-fold fluorescence enhancement) over relevant competing metal ions, sensitive to ppb levels of Hg2+ (with detection limit of 5.7 nM), and fast response toward Hg2+ (within 30 s) in aqueous solution.
