Cell nucleus localization and high anticancer activity of quinoline-benzopyran rhodium(III) metal complexes as therapeutic and fluorescence imaging agents.

Four novel rhodium(III) complexes, [Rh(QB1)Cl(DMSO)] (RhN1), [Rh(QB2)Cl(CHOH)]·CHOH (RhN2), [Rh(QB3)Cl(CHOH)]·CHOH (RhS), and [Rh(QB4)Cl(DMSO)] (RhQ), bearing quinoline-benzopyran ligands (QB1-QB4) were synthesized and used to develop highly anticancer therapeutic and fluorescence imaging agents. Compared with the QB1-QB4 ligands (IC > 89.2 ± 1.

Complexes of Zn(II) with a mixed tryptanthrin derivative and curcumin chelating ligands as new promising anticancer agents.

In this study, two novel curcumin (H-Cur)-tryptanthrin metal compounds-[Zn(TA)Cl], , Zn(TA), and [Zn(TA)(Cur)]Cl, , Zn(TAC)-were synthesized and investigated using 5-(bis-pyridin-2-ylmethyl-amino)-pentanoic acid (6,12-dioxo-6,12-dihydro-indolo[2,1-]quinazolin-8-yl)-amide (TA) and H-Cur as the targeting and high-activity anticancer chemotherapeutic moieties, respectively. They were then compared with the di-(2-picolyl)amine (PA) Zn(II) complex [Zn(PA)Cl], , Zn(PA). When compared with Zn(PA) and cisplatin, the IC values of Zn(TA) and Zn(TAC) indicated that the compounds had high cytotoxicity against A549/DDP cancer cells, implying that the H-Cur-tryptanthrin Zn(II) compounds have the potential for use as anticancer drugs.

Synthesis and biological evaluation of mixed-ligand cyclometalated iridium(III)-quinoline complexes.

With the aim of gaining new insight into the underlying apoptosis mechanisms and efficacy of cyclometalated Ir(III) complexes as metalodrugs, six new cyclometalated Ir(III)-quinoline complexes, [Ir(1a)(2pq)] (2a), [Ir(1b)(2pq)] (2b), [Ir(1c)(2pq)] (2c), [Ir(1d)(2pq)] (2d), [Ir(1e)(2pq)] (2e), and [Ir(1f)(2pq)] (2f) (2pq = 2-phenylisoquinoline), have been synthesized using 5,7-dihalo-8-hydroxylquinoline ligands (1a-1f) and [Ir(2pq)Cl] precursors and characterized. Complexes 2a-2f have shown potent anticancer activity against cisplatin-resistant SK-OV-3/DDP and A549/DDP cells (IC = 0.11-1.

Allelic and haplotypic diversity of 5'promoter region of the MICA gene.

In this study, the 5'promoter region of MHC class I chain-related gene A (MICA) was investigated in 104 healthy, unrelated Han individuals recruited from northern China, using PCR-sequencing method. Twelve variable sites were detected, which were in very strong linkage disequilibrium with each other. Twelve different MICA 5'promoter haplotypes were identified, among which Promoter-7 predominated (0.

The genetic architecture of 3'untranslated region of the MICA gene: polymorphisms and haplotypes.

In this study, the 3'untranslated region (3'UTR) of MHC class I chain-related gene A (MICA) were investigated in 104 healthy, unrelated Han individuals recruited from northern China, using PCR-sequencing method. Nine polymorphic sites were detected, which were in very strong linkage disequilibrium with each other .Seven different MICA 3'UTR alleles were identified, among which UTR1 predominated (0.

Characterization of 3'untranslated region (3'UTR) of the MICB gene.

In this study, the 3'untranslated region (3'UTR) of MHC class I chain-related gene B (MICB) were investigated in 104 healthy, unrelated Han individuals recruited from northern China, using PCR-sequencing method. Seven polymorphic sites were detected including a 2-bp deletion/insertion, a 6-bp deletion/insertion and 5 SNPs. Seven different 3'UTR alleles were identified with frequencies ranging from 0.

MICB polymorphism in a southern Chinese Han population: the identification of two new MICB alleles, MICB*005:06 and MICB*026.

In this study, we investigated the major histocompatibility complex (MHC) class I chain-related gene B (MICB) allelic variation by sequence-based typing (SBT) in 201 healthy, unrelated Han subjects from Hunan province, southern China. Eleven MICB alleles were observed, among which MICB(∗)005:02 predominated with a frequency of 64.93%.
