Optically active tetrahydropyran-3-ol was obtained by the horse liver alcohol dehydrogenase (HLADH)-catalysed reduction of tetrahydropyran-3-one, and the corresponding brosylate was prepared.Acetolysis of the optically active brosylate gave racemic 3-tetrahydropyranyl acetate as well as varying amounts of racemic tetrahydropyran-3-ol.Within experimental error, the polarimetric rate of acetolysis was the same as the previously measured tetrimetric rate.The results provide no support for the intermediacy of a bicyclic oxonium ion in the acetolysis of 3-tetrahydropyranyl brosylate.

New glucopyranosyl Schiff base zinc complexes, [Zn(GlcSal)2] (1; GlcSalH=N-(2-deoxy-beta-D-glucopyranos-2-yl-salicylaldimine) and [Zn(AcOGlcSal)2] (2; AcOGlcSalH=N-(2-deoxy-beta-D-1,3,4,6- tetraacetylglucopyranos-2-yl-salicylaldimine) were synthesized, and characterized by spectral and analytical methods. The interaction between the Zn complexes and mononucleotides was investigated by 1H-NMR, 31P-NMR and UV/VIS spectroscopies. Mononucleotides, cytidine 5′-monophosphate (CMP) and uridyl 5′-monophosphate (UMP), interacted with these complexes to form a 1: 1 complex with 1 and a 1: 2 complex with 2, depending on the presence of the OH group of glucopyranosyl substituents. The DNA-cleavage activities of 1 and 2 were studied using plasmid DNA (pBR322) in a medium of 5 mM Tris¡¤HCl/50 mM NaCl buffer in the presence of H2O 2. The DNA-cleavage activity decreased in the order of 2>1>Zn(OAc)2, indicating the significant promoting effect of the glucopyranosyl Schiff base ligand and the participation of the glucopyranosyl OH groups in the cleavage mechanism. The mechanism of the DNA cleavage by 1 and 2 was investigated by evaluation of the effect of a HO radical scavenger and a singlet-oxygen (1O 2) quencher under aerobic conditions. The former exhibited little effect, excluding the HO. radical as an active species and supporting the hydrolysis mechanism for the main process of the DNA cleavage. The latter quencher somewhat hindered the cleavage, indicating the partial participation of a 1O2 as a competitive active species in the present system. Copyright

The naturally occurring (6Z)-(¡À)-2-methoxy-6-hexadecenoic acid (1) and (6Z)-(¡À)-2-methoxy-6-octadecenoic acid (2) were synthesized in 7?8 steps with 38 and 13% overall yields, respectively, by using an acetylide coupling approach, which made it possible to obtain a 100% cis-stereochemistry for the double bonds. In a similar fashion, the acetylenic analogs (¡À)-2-methoxy-6-hexadecynoic acid (3) and (¡À)-2-methoxy-6-octadecynoic acid (4) were also synthesized in 6?7 steps with 48 and 16% overall yields, respectively. The antibacterial activity of acids 1?4 was determined against clinical isolates of methicillin-resistant Staphylococcus aureus (ClMRSA) and Escherichia coli. Among the series of compounds, acid 4 was the most active bactericide towards CIMRSA displaying IC50s (half maximal inhibitory concentrations) between 17 and 37?mug/mL, in sharp contrast to the 6-octadecynoic acid, which was not bactericidal at all. On the other hand, acids 1 and 3 were the only acids that displayed antibacterial activity towards E. coli., but 1 stood out as the best candidate with an IC50 of 21?mug/mL. The critical micelle concentrations (CMCs) of acids 1?4 were also determined. The C18 acids 2 and 4 displayed a five-fold lower CMC (15?20?mug/mL) than the C16 analogs 1 and 3 (70?100?mug/mL), indicating that 4 exerts its antibacterial activity in a micellar state. None of the studied acids were inhibitory towards S. aureus DNA gyrase discounting this type of enzyme inhibition as a possible antibacterial mechanism. It was concluded that the combination of alpha-methoxylation and C-6 unsaturation increases the bactericidal activity of the C16 and C18 FA towards the studied bacterial strains. Acids 1 and 4 stand out as viable candidates to be used against E. coli and CIMRSA, respectively.

Lectin-carbohydrate interactions are important for many biological processes of high pharmaceutical interest. Multi-valent carbohydrate conjugates (glycoclusters) have been frequently used to study and manipulate these interactions. In this report, we present the synthesis of trimeric glucose and mannose conjugates that have been assembled with an AB3 scaffold based on adamantane. Several neoglycoconjugates bearing three carbohydrates have been synthesized with different ethylene glycol spacers between the sugar moieties and the adamantyl core. An additional orthogonal functionality at the remaining adamantane bridgehead position allows the conjugation of these trimeric cluster glycosides to other functional molecules such as fluorescent dyes or a solid support for the construction of glycoarrays. We have evaluated the binding properties of trivalent carbohydrate derivatives to ConA as a model lectin in solution by STD-NMR and on a lectin array by using fluorescent glycoconjugates.

The preparation, magnetic and spectroscopic properties, crystal and molecular structures of binuclear complexes of formulae [Cu2(dpyam)2(OH)2(ONO2)2] (I), [Cu2(dpyam)2(O2CH)4(OH 2)].H2O (II) are described. (I) consists of pairs of copper atoms linked by two hydroxo bridges. The co-ordination geometry at each copper atom is distorted square-pyramidal, the basal plane consisting of two hydroxo oxygen atoms and two nitrogen atoms from a dpyam ligand, while the axial co-ordination sites are occupied by nitrate oxygen atoms. The copper(II) ions in (II) are also in a distorted square-pyramidal environment. They are bridged by a formate group in an anti-syn configuration from a basal position to an axial position, while another axial position is occupied by the water oxygen atom. From magnetic susceptibility measurements at room temperature, both complexes are found to exhibit antiferromagnetic interactions and some magneto-structural trends are discussed.

New drugs are urgently needed for the treatment of tropical parasitic diseases such as leishmaniasis and human African trypanosomiasis (HAT). This work involved a high-throughput screen of a focussed kinase set of ?3400 compounds to identify potent and parasite-selective inhibitors of an enzymatic Leishmania CRK3-cyclin6 complex. The aim of this study is to provide chemical validation that Leishmania CRK3-CYC6 is a drug target. Eight hit series were identified, of which four were followed up. The optimisation of these series using classical SAR studies afforded low-nanomolar CRK3 inhibitors with significant selectivity over the closely related human cyclin dependent kinase CDK2. Selective at last: [1,2,4]Triazolo[1,5-a]pyridines, aminopyrazoles, and disubstituted ureas were explored as potent and parasite-selective inhibitors of an enzymatic Leishmania CRK3-cyclin6 complex. Optimisation of these series using classical SAR studies afforded low-nanomolar CRK3 inhibitors with significant selectivity over the closely related human cyclin-dependent kinase CDK2.
