Huang, Jian-Dong published the artcileTetra-(acetyl piperazine phenoxy) phthalocyaninato zinc complexes and their proteins conjugates: synthesis, characterisation and photodynamic activities, Computed Properties of 67914-60-7, the publication is Wuji Huaxue Xuebao (2006), 22(3), 435-442, database is CAplus.

Two zinc phthalocyanines, tetra-α-[4-(4-acetyl piperazine) phenoxy] phthalocyaninato zinc (C80H72N16O8Zn) and tetra-β-[4-(4-acetyl piperazine) phenoxy] phthalocyaninato zinc (C80H72N16O8Zn), have been synthesized and characterized with 1H NMR, MS, IR and elemental anal. The electronic absorption spectra of two complexes in common organic solvents (N,N-DMF, THF, n-octanol) were typical for nonaggregated phthalocyanines, showing a Q band at 693∼698 nm for 1 and 681 ∼ 682 nm for 2. This indicates that the Q band of zinc phthalocyanine with the substituted groups located in the α position is largely red shifted than that in the β position. The spectral features of complexes 1 and 2 in aqueous media suggest the α-substituted groups are more effective than β-substituted groups to hinder the aggregation of phthalocyanine mol. The interactions between two complexes with serum albumin and transferrin (BSA, HSA and apoTf) were investigated by absorption and fluorescence spectroscopy. The binding constants were found to be (1 ∼ 20) × 105 mol-1·L. By comparison, β-substituted 2 had stronger combining ability with albumin than that of α-substituted 1. The non-covalent conjugates (1-BSA, 2-BSA, 1-HSA, 1-apoTf and 1-FeTf) with the molar ratio of about 1 : 1 have also been prepared The photodynamic activities of two complexes and their bioconjugates against MCF-7 mammary tumor cells were examined The result shows that the photocytotoxicities of conjugates are higher than that of complexes 1 ∼ 2 and follows the order 1-BSA > 1-FeTf > 1-HSA, 1-apoTf > 2-BSA > 1>2.

The antitumor activity of thalidomide derivatives [i.e., 2-(2,6-dioxo-3-piperidinyl)-1H-isoindole-1,3(2H)-dione derivatives] was studied. A method for the synthesis of the title compounds is reported here. According to the structure of thalidomide, starting from β-D-glucosamine hydrochloride, twenty compounds were designed and synthesized. Product structures were determined by NMR, IR, MS. The target compounds were evaluated for their anticancer activity. The survival of 4T1 cells was determined Compounds substituted by a 3,4,6-tri-O-acetyl glucopyranoside have better antitumor activity than thalidomide dose.

The effect of the side chain in (4-substituted)-1-piperazinyl on the antifungal activity of fluconazole compounds was studied. Thirteen title compounds were synthesized and confirmed by the elementary anal., 1H-NMR and IR spectra. The MICs of all the title compounds were determined by the method recommended by the National Committee for Clin. Laboratory Standards (NCCLS) using the RPMI1640 test medium. The results of the preliminary antifungal test showed that all the title compounds exhibited potent antifungal activities. The activities of the eight compounds thus prepared were more than 4 times as high as that of fluconazole and equal to that of ketoconazole against Candida albicans in vitro. The lipid/water distribution coefficient and stereochem. have important influence on the antifungal activities of the title compounds
