Spectroelectrochemical properties of a Ru(ii) complex with a thiazolo[5,4-d]thiazole triarylamine ligand

A new bis-chelating ligand containing a triarylamine electron donor core fused with a thiazolo-thiazole electron acceptor, N,N?-(thiazolo[5,4-d]thiazole-2,5-diylbis(4,1-phenylene))bis(N-(pyridin-2-yl)pyridin-2-amine) (1) has been synthesised. This non-innocent ligand exhibits interesting electronic and spectral properties that can be tuned as a function of its redox state. In particular, modulation of the electronic state can be used to turn the fluorescence on and off. A dinuclear Ru(ii) terpyridine complex, [Ru2(tpy)2Cl2(1)](PF6)2 (2) was subsequently synthesised and the properties of each of the accessible redox states explored using in situ spectroelectrochemical techniques.

Ruthenium(II)-arene complexes with naphthalimide-tagged N,O- and N,N-chelating ligands: Synthesis and biological evaluation

A new family of ruthenium(II)-arene complexes with naphthalimide functionalized N,O- and N,N-chelating ligands of the general formula [Ru(eta6-p-cymene)Cl(L)] (2b-4b) (where: L = 4-[N-(2-((2-hydroxy-5-Br-phenyl)methyl imino)ethyl)]-N-butyl-1,8-naphthalimide (2a), 4-[N-(2-((2-hydroxy-5-Cl-phenyl)methyl imino)ethyl)]-N-butyl-1,8-naphthalimide (3a), and N-butyl-4-[N-(2-((2-hydroxy-5-NO2-phenyl)methylimino)ethyl)]-N-butyl-1,8-naphthalimide (4a), and [Ru(eta6-p-cymene) Cl(L?)]Cl (8b-9b) (where L? = N-(2,2?-dipyridylaminoethyl)-1,8-naphthalimide (8a) and N-(2,2?-dipyridylaminopropyl)-1,8-naphthalimide (9a) have been synthesized and characterized. The in vitro cytotoxic activities of the ligands (2a, 9a) and the complexes (2b-4b, and 8b-9b) have been evaluated against the human melanoma skin cancer (CRL7687) and normal noncancerous (CA-M75) cell lines. All the compounds exhibit potent cytotoxic activities with IC50 values of ?1 muM or less but displayed variable selectivity. The compounds with N,O-ligands were found to be less selective than those containing N,N-chelating ligands. Notably, complex 9b displayed the highest selectivity towards cancer cells over health cells. The interactions of the compounds with calf thymus DNA (CT-DNA) have also been investigated by UV-Vis and fluorescence spectra, ethidium bromide displacement assay and gel electrophoretic studies, which revealed that the compounds bind to CT-DNA moderately presumably through an intercalative mode.

Synthesis and activity of putative small-molecule inhibitors of the F-box protein SKP2

The tetrahydropyran 4-(((3-(2,2-dimethyltetrahydro-2H-pyran-4-yl)-4-phenylbutyl)amino)methyl)-N,N-dimethylaniline was reported to disrupt the SCFSKP2 E3 ligase complex. Efficient syntheses of this tetrahydropyran derivative and analogues, including the des-dimethyl derivative 4-(((3-(tetrahydro-2H-pyran-4-yl)-4-phenylbutyl)amino)methyl)-N,N-dimethylaniline, are described. The enantiomers of the des-dimethyl compound were obtained using Evans’ chiral auxiliaries. Structure-activity relationships for these tetrahydropyrans and analogues have been determined by measurement of growth-inhibitory activities in HeLa cells, which indicated a non-specific mechanism of action that correlates with inhibitor lipophilicity. However, preliminary data with (R)-and (S)-4-(((3-(tetrahydro-2H-pyran-4-yl)-4-phenylbutyl)amino)methyl)-N,N-dimethylaniline showed enantioselective inhibition of the degradation of p27 in a cell-based assay that acts as a reporter of SKP2 activity.

Intermolecular alkyl radical additions to enantiopure N-tert-butanesulfinyl aldimines

The sulfinyl group in (R)-N-tert-butanesulfinyl aldimines provides efficient control of the stereoselectivity in the intermolecular reactions with alkyl radicals. The methodology is applicable to aryl, heteroaryl, benzyl, and alkynyl imines, even those containing CN, CO2Me, COR, and OH groups. The best results are attained with hindered radicals (tertiary and secondary ones) without C=N bond reduction. This reaction complements the well-established organometallic additions to N-sulfinyl aldimines to obtain enantiomerically pure functionalized alpha-branched primary amines.

Structurally simple, potent, Plasmodium selective farnesyltransferase inhibitors that arrest the growth of malaria parasites

Third world nations require immediate access to inexpensive therapeutics to counter the high mortality inflicted by malaria. Here, we report a new class of antimalarial protein farnesyltransferase (PFT) inhibitors, designed with specific emphasis on simple molecular architecture, to facilitate easy access to therapies based on this recently validated antimalarial target. This novel series of compounds represents the first Plasmodium falciparum selective PFT inhibitors reported (up to 145-fold selectivity), with lead inhibitors displaying excellent in vitro activity (IC50 < 1 nM) and toxicity to cultured parasites at low concentrations (ED50 < 100 nM). Initial studies of absorption, metabolism, and oral bioavailability are reported. Interested yet? Keep reading other articles of 50675-18-8!, 50675-18-8

Carbohydrate-binding specificity of silkworm lectin.

The binding specificity of a lectin from the hemolymph of silkworm larvae was examined quantitatively by taking advantage of the fluorospectrophotometric properties of the lectin. On excitation at 280 nm, the lectin fraction gave a fluorescence-emission spectrum centered at 336 nm, which was attributable to tryptophan residues. The fluorescence could be completely quenched by the addition of specific saccharides. The affinity constants of the silkworm lectin with specific saccharides were calculated from the changes in intensities of fluorescence-difference spectra induced by the saccharides. The silkworm lectin had the highest affinity for dermatan sulfate and hyaluronic acid, followed by protuberic acid, heparin, and chondroitin sulfate A. Among monosaccharides tested, only D-glucuronic acid and N-acetyl-neuraminic acid induced weak but significant quenching, and their affinity constants were found to be low. These results indicate that the silkworm lectin has a strong affinity for carboxyl groups, especially alpha-L-iduronic acid residues, in the saccharides. In most cases, sulfate groups on the saccharides interfere with the specific interactions.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 14215-68-0, and how the biochemistry of the body works., 14215-68-0
