Src family kinases (SFKs) are nonreceptor tyrosine kinases that are reported to be critical for cancer progression. We report here a novel subseries of C-5-substituted anilinoquinazolines that display high affinity and specificity for the tyrosine kinase domain of the c-Src and Abl enzymes. These compounds exhibit high selectivity for SFKs over a panel of recombinant protein kinases, excellent pharmacokinetics, and in vivo activity following oral dosing. N-(5-Chloro-1,3-benzodioxol-4-yl)-7-[2-(4-methylpiperazin-1-yl)ethoxy]-5- (tetrahydro-2H-pyran-4-yloxy)quinazolin-4-amine (AZD0530) inhibits c-Src and Abl enzymes at low nanomolar concentrations and is highly selective over a range of kinases. AZD0530 displays excellent pharmacokinetic parameters in animal preclinically and in man (t1/2 = 40 h). AZD0530 is a potent inhibitor of tumor growth in a c-Src-transfected 3T3-fibroblast xenograft model in vivo and led to a significant increase in survival in a highly aggressive, orthotopic model of human pancreatic cancer when dosed orally once daily. AZD0530 is currently undergoing clinical evaluation in man.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11. In a Article£¬once mentioned of 499-40-1, SDS of cas: 499-40-1

The interaction of NiCl2 with the non-steroidal anti-inflammatory drug indomethacin (Hindo) resulted in the formation of a series of mixed-ligands mononuclear complexes bearing the oxygen-donor methanol (MeOH) and/or the nitrogen-donors 2,2?-bipyridine (bipy), 1,10-phenanthroline (phen), 2,2?-bipyridylamine (bipyam) and 2,2?-dipyridylketone oxime (Hpko) as co-ligands. The resultant complexes [Ni(indo-O)2(MeOH)4] 1, [Ni(indo-O,O?)(bipyam)2]Cl 2, [Ni(indo-O)2(bipy)(MeOH)2] 3, [Ni(indo-O,O?)2(bipyam)] 4, [Ni(indo-O)2(phen)(MeOH)2] 5 and [Ni(indo-O)2(Hpko-N,N?)2] 6 were characterized by diverse physicochemical and spectroscopic techniques. The structure of complex 2 was determined by single-crystal X-ray crystallography. Furthermore, complexes 1?6 were investigated for their biological activity. The potential antioxidant activity of the complexes was evaluated by examining their in vitro ability to scavenge free radicals such as 1,1-diphenyl-picrylhydrazyl (DPPH), 2,2?-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and hydroxyl (OH) radicals. All complexes are better radical scavengers than free indomethacin. The interaction of the complexes with calf-thymus (CT) DNA was monitored by UV?Vis spectroscopy, cyclic voltammetry, DNA-viscosity measurements and competitive studies with ethidium bromide (EB). According to the experimental findings, the complexes can bind tightly to CT DNA via intercalation and can displace EB from its EB-DNA conjugate. The interaction of the complexes with human serum albumin (HSA) and its homologue bovine serum albumin (BSA) was studied by fluorescence emission spectroscopy and the corresponding binding constants were calculated. The complexes bind tightly and reversibly to both albumins.

A general and efficient protocol for the palladium-catalyzed functionalization of mono- and polyglycosyl thiols by using the palladacycle precatalyst G3-XantPhos was developed. The C-S bond-forming reaction was achieved rapidly at room temperature with various functionalized (hetero)aryl-, alkenyl-, and alkynyl halides. The functional group tolerance on the electrophilic partner is typically high and anomer selectivities of thioglycosides are high in all cases studied. New sulfur nucleophiles such as thiophenols, alkythiols, and thioaminoacids (cysteine) were also successfully coupled to lead to the most general and practical method yet reported for the functionalization of thiols.

Ferrocenes are versatile ligand scaffolds, complexes of which have found numerous applications in catalysis. Structurally similar but of higher redox stabilites are sandwich complexes of the [Re(eta6-arene)2]+ type. We report herein routes for conjugating potential ligands to a single or to both arenes in this scaffold. Since the arene rings can freely rotate, the [Re(eta6-arene)2]+ has a high degree of structural flexibility. Polypyridyl ligands were successfully introduced. The coordination of Co(ii) to such a model tetrapyridyl-Re(i)-bis-benzene complex produced a bimetallic Re(i)-Co(ii) complex. To show the stability of the resulting architecture, a selected complex was subjected to photocatalytic reactions. It showed good activity in proton reduction over a long time and did not decompose, corroborating its extraordinary stability even under light irradiation. Its activity compares well with the parent catalyst in turn over numbers and frequencies. The supply of electrons limits catalytic turnover frequency at concentrations below ?10 muM. We also show that other ligands can be introduced along these strategies. The great diversity offered by [Re(eta6-arene)2]+ sandwich complexes from a synthetic point allows this concept to be extended to other catalytic processes, comparable to ferrocenes.

The nickel(ii) complexes with the non-steroidal anti-inflammatory drug naproxen (Hnap) were prepared in the absence or presence of the nitrogen-donor heterocyclic ligands 2,2?-bipyridine (bipy), 1,10-phenanthroline (phen), 2,2?-bipyridylamine (bipyam), 2,2?-dipyridylketone oxime (Hpko) or pyridine (py) and were characterized by diverse techniques. The crystal structures of complexes [Ni(nap-O)(nap-O,O?)(bipy)(MeOH)], 2 and [Ni(nap-O)(nap-O,O?)(phen)(H2O)] 3 were determined by X-ray crystallography. The antioxidant activity of the complexes was evaluated in vitro by examining their ability to scavenge 1,1-diphenyl-picrylhydrazyl, 2,2?-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) and hydroxyl radicals and to inhibit soybean lipoxygenase. The ability of the complexes to intercalate to calf-thymus DNA was monitored by diverse techniques (UV-vis spectroscopy, cyclic voltammetry, viscosity measurements) and competitive studies with ethidium bromide. The interaction of the complexes with serum albumins was studied by fluorescence emission spectroscopy and the corresponding binding constants were calculated. The bio-activity of the complexes was compared to previously reported metal-naproxen complexes and the structural factors responsible for enhanced activity are discussed.

A novel rhodamine B-based fluorescent probe (RML) for lysosomal pH was developed by integrating a 4-(2-aminoethyl)morpholine moiety, which is a lysosome-targetable group, into a rhodamine B fluorophore, which is associated with rhodamine B dyes possessing spirocyclic (non-fluorescent) and ring-opening (fluorescent) forms with response to pH. The probe responded to acidic pH at low concentration in a short amount of time. In addition, RML showed good membrane permeability and brilliant selectivity among various amino acids and metal cations. RML exhibited an 80-fold increase in fluorescence intensity at 583 nm throughout the pH range of 7.40-4.00 with a pKa of 5.16, which indicates that RML is valuable for studying intracellular acidic organelles. Moreover, RML has been successfully applied in HeLa cells, and the results demonstrated that RML could selectively stain lysosomes in living HeLa cells. Note that RML could be used to detect the pH increase in lysosomes induced by bafilomycin A1 within HeLa cells.
