Synthetic studies of moenomycin a disaccharide analogues. Protection of the anomeric centre with long-chain protective groups

Two new C9 protecting groups for the anomeric position of carbohydrates are reported. Methods both for their introduction and removal are described. The C9-protected compounds are much less polar than the corresponding allyl protected analogues. The new protecting group chemistry has been used to prepare compound 17 en route to a disaccharide analogue of the antibiotic moenomycin A.

Synthesis of amino-acid-, carbohydrate-, coumarin-, and biotin-labelled oligo[(R)-3-hydroxybutanoic acids] (OHB)

The benzyl esters 1- 3 of oligo[(R)-3-hydroxybutanoic acids] (OHB) containing 2, 16, or 32 HB units were coupled at the hydroxy terminus with arginine (by esterification with carbodiimide), with glucose (by acetalization with glucosyl trichloroacetimidate), and with 7- (dimethylamino)coumarin-4-acetic acid and biotin (by amide formation through a glycine linker) to give, after deprotection(s), the corresponding ‘labelled’ OHB acids 7-9, 12, 13, 25, 26, 33, and 34 (Schemes 1, 4, and 5). The respective novel 16- and 32mer derivatives exhibit distinct water solubility (Table) or may be detected (in minute amounts) by fluorescence spectroscopy, properties required for biochemical investigations.

The role of glucuronidation in drug resistance

The final therapeutic effect of a drug candidate, which is directed to a specific molecular target strongly depends on its absorption, distribution, metabolism and excretion (ADME). The disruption of at least one element of ADME may result in serious drug resistance. In this work we described the role of one element of this resistance: phase II metabolism with UDP-glucuronosyltransferases (UGTs). UGT function is the transformation of their substrates into more polar metabolites, which are better substrates for the ABC transporters, MDR1, MRP and BCRP, than the native drug. UGT-mediated drug resistance can be associated with (i) inherent overexpression of the enzyme, named intrinsic drug resistance or (ii) induced expression of the enzyme, named acquired drug resistance observed when enzyme expression is induced by the drug or other factors, as food-derived compounds. Very often this induction occurs via ligand binding receptors including AhR (aryl hydrocarbon receptor) PXR (pregnane X receptor), or other transcription factors. The effect of UGT dependent resistance is strengthened by coordinate action and also a coordinate regulation of the expression of UGTs and ABC transporters. This coupling of UGT and multidrug resistance proteins has been intensively studied, particularly in the case of antitumor treatment, when this resistance is “improved” by differences in UGT expression between tumor and healthy tissue. Multidrug resistance coordinated with glucuronidation has also been described here for drugs used in the management of epilepsy, psychiatric diseases, HIV infections, hypertension and hypercholesterolemia. Proposals to reverse UGT-mediated drug resistance should consider the endogenous functions of UGT.

Crown-linked dipyridylamino-triazine ligands and their spin-crossover iron(ii) derivatives: Magnetism, photomagnetism and cooperativity

The syntheses, crystallography and magnetic properties of a series of compounds of formula trans-[FeII(L1)2(NCX) 2] (X = S, Se, BH3 (1-3)), cis-[FeII(L 2)(NCX)2]·CH2Cl2 (X = S, Se, BH3 (4-6)) and trans-[FeII(L3)(NCX) 2]n (X = S, Se (7-8)) are described (L1 = 6-chloro-N2,N2-diethyl-N4,N4- di(pyridin-2-yl)-1,3,5-triazine-2,4-diamine, L2 = 6,6?-(1,4,10,13-tetraoxa-7,16-diazacyclooctadecane-7,16-diyl)bis(N 2,N2-diethyl-N4,N4-di(pyridin-2-yl)- 1,3,5-triazine-2,4-diamine, L3 = 6,6?-(1,4,10,13-tetraoxa-7,16- diazacyclooctadecane-7,16-diyl)bis(N2,N2,N 4,N4-tetra(pyridin-2-yl)-1,3,5-triazine-2,4-diamine)). The magnetostructural properties of 1-8 have been probed in detail by variable temperature magnetic measurements and crystallographic methods. 1-6 display mononuclear structures while 7 and 8 form 1-D chain structures. Complexes 4-6 have the potential to form 1D-chains via L2 bridging, but instead form mononuclear complexes. Magnetic studies show that complexes 1, 2, and 4 remain in the high-spin (HS) state at all temperatures. An aged, dry, powdered sample of 3 gives an abrupt HS to LS transition (T1/2 = 200 K), while a freshly prepared, powdered sample of 3·1.5H2O displays thermal hysteresis (Delta = 7 K). Complexes 5, 6 and 7 undergo a gradual spin transition with T1/2 values of 100 K, 150 K and 130 K, respectively. Cooperativity parameters are compared, with 3 showing cooperativity (positive C) and 5 and 6 showing anticooperativity. Photomagnetic LIESST (light induced excited spin state trapping) studies were performed on complexes 5 and 6 and reveal T(LIESST) values lower than 60 K. An attempt has been made to understand the electronic structure of complex 3 and its cooperativity behaviour using density functional methods, the calculations reproducing the sign and, in part, the magnitude of the cooperativity.

Copper(I) carbonyl and copper(II) acetato complexes with 2,2′-dipyridylamine and halide anions. Crystal and molecular structures of carbonylchloro(2,2′-dipyridylamine)copper(I) and acetatochloro(2,2′-dipyridylamine)copper(II)

Series of [Cu(I)dipyam(CO)X], [Cu(II)dipyam(CH3CO2)X] and [Cu(II) (dipyam)2(CH3CO2)]X complexes (dipyam = 2,2′-dipyridylamine; X = Cl(-), Br(-),I(-)) were synthesized and the structures of the title compounds were d etermined by X-ray diffraction methods. Crystallographic details for complexes [Cu(I)dipyam(CO)Cl] (1) and [Cu(II)dipyam(CH3CO2)Cl] (2) are as follows: complex 1, triclinic, space group P1- with a = 9.944(3), b = 9.450(3), c = 7.053(3)A, alpha = 69.50(2), beta = 91.81(2), gamma= 76.33(2)°, Z = 2; complex 2, triclinic, space group P1- with a = 10.093(3), b = 9.098(3), c = 7.444(2)A, alpha = 106.24(2), .bet a. = 96.91(2), gamma = 78.87(2)°, Z = 2. The dry carbonyl complexes are thermostable at 100°C or more, but their formation was reversible in solution even at room temperature. Thermal and chemical stabilities increase from the chloro to the iodo species. Among the acetatoderivatives the chloro and bromo mono-dipyam complexes were easily form ed, while the iodide gave preferentially the bis-dipyam complex. Each series of the complexes gave very similar IR spectra in the range 3800-250cm**-1. For the carbonyl derivatives the patterns of the far-IR 250-60 cm**-1 regions were shown and the nu(Cu-X) frequencies assigned.

A facile and efficient method for synthesis of macrocyclic lipoglycopeptide

An efficient and practical method for macrocyclic lipoglycopeptide synthesis was developed and utilized to synthesize lipoglycosylated derivatives of Tyrocidine A. The method is based on solid-phase peptide synthesis using 2-chlorotrityl resin as the solid-phase support and lipoglycosyl amino acids as building blocks. This synthetic method should be generally applicable to various macrocyclic lipoglycopeptides.

Glycosylimidates, 8. – Synthesis of 1-Thioglycosides

As expected, the reactive acetyl-protected O-(alpha-D-glucopyranosyl) trichloroacetimidate 3 reacts with S-nucleophiles and trifluoroborane-ether as catalyst to yield exclusively 1-thio-beta-D-glucopyranosides with inversion of the configuration.The corresponding benzyl-protected alpha-trichloroacetimidate 4 affords with retention of the configuration alkyl 1-thio-alpha-D-glucopyranosides.The importance of alkyl 1-thio-beta-D-galactopyranosides in enzyme induction was reason to apply this convenient and efficient glycosyl-transfer reaction to the synthesis of isopropyl 1-thio-beta-D-galactopyranoside (12a) and the sodium salt of 1-thio-beta-D-galactopyranose (12b), respectively.

Bactericidal activity of different oxovanadium(IV) complexes with Schiff bases and application of chelation theory

Oxovanadium(IV) complexes have been synthesized and characterized the general composition [VOL(A)], where H2L = salicylidene-o-aminothiophenol A1 = bis(benzylidene)ethylenediamine, A2 = bis(acetophenone)ethylenediamine, A3 = 2,2?-bipyridylamine, A4 = bis(benzylidene) – 1,8-diaminonaphthalene, A5 = thiophene-o-carboxaldeneaniline and A6 = thiophene-o-carboxaldene-p-anisidine. Spectral studies indicate that the oxovanadium(IV) complexes assume a six-coordinate octahedral geometry. The antibacterial activities of the complexes against Salmonella typhi, Escherichia coli and Serratia mercescens are higher as compared to the free ligands, vanadyl sulphate, and the control (DMSO) but of moderate activity as compared to the standard drug (tetracycline).
