Antitumor platinum (II) compound using camphor acid radical as ligand

The present invention discloses platinum (II) complexes with effective anticancer activity, characterized in that the new platinum (II) complexes are formed by reacting the anionic ligand of Camphoric radicals with the cationic ligand of amine platinum. The preparation process of these complexes and the in vitro inhibition effect of leukemic cell, oophoroma cell, hepatoma cell and pulmonary carcinoma cell with the typical compounds of the present invention are also disclosed. The structures of the present complexes are represented by the following formulas: (1), (2) and (3), wherein the Camphoric radicals in formula (l), (2) and (3) can be DL type raceme, D type optical isomer [1R, 3S) - (+) -Camphoric radical] or L type optical isomer [(1S, 3R)-(-)-Camphoric radical]. In formula (1) R is the same, representing hydrogen atom, C1-5alkyl or Cl-8oxaalkyl; In formula (2) the cyclohexanediamine is 1,2-t­rans-cyclohexanediamine, wherein both of the two chiral carbon atoms (marked with *) have the absolute configuration of R or S; In formula (3) R1 and R2 linked to the 4, 5-bis (aminomethyl) -2-alkyl-1, 3-­dioxolane, same or different, independently represent hydrogen atoms or C1-5 alkyl, or link to one carbon to form a cycle, wherein both of the two chiral carbon atoms(marked with *) have the absolute configuration of R or S. The platinum complexes of the present invention include all stereomers and mixtures of compounds represented by above formulas.

Method for detecting aluminum ions and tin ions in water phase by using water-soluble porphyrin probe

The invention relates to a method for high selective identification of aluminum ions and tin ions in water phase by using a water-soluble porphyrin probe. According to the method, an ultraviolet-visible spectrophotometer and a fluorescence spectrophotometer are used for detecting the characteristic absorption peak and emission peak of water-soluble porphyrin solution to red shift to certain wavelength respectively to identify the existence of aluminum ions or tin ions in water phase; and fluorescence intensity of human lung carcinoma A549 cells are observed under an upright fluorescent microscope to judge the existence of aluminum ions. In the invention, the sensitivity is high, and rapid detection can be realized; the porphyrin probe has a simple structure and is easy to prepare, and both excitation wavelength and emission wavelength are within visible region; the operation is simple, the fabrication cost is low, and the reagent used and the operation process have no toxic and side effects; and the probe has good selectivity to aluminum ions or tin ions, metal ions such as natrium ions, kalium ions, magnesium ions, copper ions, lead ions and the like have no interference on detection, and the invention can realize detection of aluminum ions in cells.
