Peptide‐Biphenyl Hybrids as Calpain Inhibitors
Authors: Montero Ana , Mann Enrique , Chana Antonio , Herradón Bernardo
Published: March 2004

Calpain is a cysteine protease that is activated by Ca2+. The over‐activation of calpain, which occurs on increasing Ca2+ concentration, causes a variety of diseases. This paper reports experimental results on the inhibition of calpain I (μ‐calpain) by peptidebiphenyl hybrids. We have found that some peptidebiphenyl hybrids, with aromatic amino acids in the peptide chains, inhibit calpain with IC50 values in the nanomolar range. Since the peptidebiphenyl hybrids reported in the present paper do not posses a reactive electrophilic functionality, we hypothesize that they interfere with the activation of calpain by Ca2+, and present experimental and computational results on the binding of peptidebiphenyl hybrids to Ca2+.
Limbetazulone: a New ‘Decahydro‐8‐oxanaphtho[2,1‐f]azulen‐7‐one’ Diterpenoid from Ballota limbeta, and Occurence of Two Conformational Isomers in the Crystal
Authors: Riaz Muhammad , Krohn Karsten , Malik Abdul , Flörke Ulrich
Published: March 2004

A new diterpenoid, limbetazulone (=(3S,4S,4aR,12bS)‐1,2,3,4,4a,5,6,11,12,12b‐decahydro‐3‐hydroxy‐4‐ (hydroxymethyl)naphtho[1′,2′: 5,6]cyclohepta[1,2‐b]furan‐7(7H)‐one; 1), with the very rare ‘naphtho[2,1‐f]azulene‐7‐one’ skeleton, was isolated from the aerial parts of the Asian medicinal plant Ballota limbeta. Its structure was established by extensive spectroscopic investigations, especially 1D and 2D NMR. X‐Ray diffraction studies showed the presence of two conformational isomers (1a and 1b) in the crystal.
Guanine 6‐O‐Methylation Pattern within the Dioxin Responsive Element of the CYP1A1 Enhancer Shows Two Critical Guanines for AhR/ARNT Binding
Authors: Oesch‐Bartlomowicz Barbara , Janssen Kai , Wiss Oliver , Oesch Franz
Published: March 2004

The core‐recognition motif for TCDD‐liganded AhR/ARNT complex of the dioxin‐responsive element (DRE) contains four guanine residues, three on the antisense (5′‐TT/AGCGTG‐3′) and one on the sense (5′‐CACGCA/TA‐3′) strand. It has been reported that, in methylation‐protection and methylation‐interference assays, the TCDD‐liganded AhR/ARNT contacts all four guanine residues. On the other hand, it is known that some anticancer drugs, and various environmental and workplace chemicals, including strongly human carcinogenic nitrosoamines, lead to the highly miscoding 6‐O‐methylation of guanine. In the present study, we have investigated whether specific methylation of guanine at the 6‐O‐position interferes with the binding of TCDD‐liganded AhR/ARNT complex to its recognition motif in the CYP1A1 enhancer, and how individual 6‐O‐methylated guanines contribute to this interference. We found that only two 6‐O‐methylguanine residues are critical: the closest to the 5′‐end within the three‐nucleotide sequence (5′‐GTG‐3′), identical to a half‐site E‐box element, on the antisense strand, and the only guanine on the sense strand. In contrast, the 6‐O‐methylguanine closest to the 5′‐end (well) and the one closest to the 3′‐end (to a lesser extent), both on the antisense strand, were still able to bind the TCDD‐liganded AhR/ARNT complex. This shows that the 6‐O‐methylation of guanine in the core sequences of CYP1A1 enhancer interferes with the binding of the ligand‐activated AhR/ARNT complex in a differentially selective manner; it fully impedes binding of this complex to DRE (the prerequisite of most of the toxic effects of TCDD) only when one of the two particular guanines is methylated at the 6‐O‐position.

Two new cyclohexadepsipeptides have been isolated from the fungus Isaria. Fungal growth in solid media yielded hyphal strands from which peptide fractions were readily isolable by organic‐solvent extraction. Two novel cyclodepsipeptides, isaridin A and isaridin B, have been isolated by reverse‐phase HPLC, and characterized by ESI‐MS and 1H‐NMR. Single crystals of both peptides have been obtained, and their 3D structures were elucidated by X‐ray diffraction. The isaridins contain several unusual amino acid residues. The sequences are cyclo(β‐Gly‐HyLeu‐Pro‐Phe‐NMeVal‐NMePhe) and cyclo(β‐Gly‐HyLeu‐β‐MePro‐Phe‐NMeVal‐NMePhe), where NMeVal is N‐methylvaline, NMePhe N‐methylphenylalanine, and HyLeu hydroxyleucine (=2‐hydroxy‐4‐methylpentanoic acid). The two peptides differ from one another at residue 3, isaridin A having an (S)‐proline at this position, while β‐methyl‐(S)‐proline (=(2S,3S)‐2,3,4,5‐tetrahydro‐3‐methyl‐1H‐pyrrole‐2‐carboxylic acid) is found in isaridin B. The solid‐state conformations of both cyclic depsipeptides are characterized by the presence of two cis peptide bonds at HyLeu(2)‐Pro(3)/HyLeu(2)‐β‐MePro(3) and NMeVal(5)‐NMePhe(6), respectively. In isaridin A, a strong intramolecular H‐bond is observed between Phe(4)CO⋅⋅⋅HNβ‐Gly(1), and a similar, but weaker, interaction is observed between β‐Gly(1)CO⋅⋅⋅HNPhe(4). In contrast, in isaridin B, only a single intramolecular H‐bond is observed between β‐Gly(1)CO⋅⋅⋅HNPhe(4).
Effect of Inorganic Anions on the Morphology and Structure of Magnesium Calcite
Authors: Kralj Damir , Kontrec Jasminka , Brečević Ljerka , Falini Giuseppe , Nöthig‐Laslo Vesna
Published: March 2004

Calcium carbonate was precipitated from calcium hydroxide and carbonic acid solutions at 25 °C, with and without addition of different magnesium (MgSO4, Mg(NO3)2and MgCl2) and sodium salts (Na2SO4, NaNO3and NaCl) of identical anions, in order to study the mode of incorporation of magnesium and inorganic anions and their effect on the morphology of calcite crystals over a range of initial reactant concentrations and limitedci(Mg2+)/ci(Ca2+) molar ratios. The morphology, crystal size distribution, composition, structure, and specific surface area of the precipitated crystals, as well as the mode of cation and anion incorporation into the calcite crystal lattice, were studied by a combination of optical and scanning electron microscopy (SEM), electronic counting, a multiple BET method, thermogravimetry, FT‐IR spectroscopy, X‐ray diffraction (XRD), and electron paramagnetic resonance (EPR) spectroscopy. In the systems of high initial relative supersaturation, precipitation of an amorphous precursor phase preceded the formation of calcite, whereas in those of lower supersaturation calcite was the first and only polymorphic modification of calcium carbonate that appeared in the system. The magnesium content in calcite increased with the magnesium concentration in solution and was correlated with the type of magnesium salt used. Mg incorporation caused the formation of crystals elongated along the calcitecaxis and, in some cases, the appearance of new {011} faces. Polycrystalline aggregates were formed when theci(Mg2+)/ci(Ca2+) molar ratios in solution were increased. Addition of sulfate ions, alone, caused formation of spherical calcite polycrystalline aggregates.
Silsesquioxane‐Based Homogeneous and Heterogeneous Epoxidation Catalysts Developed by Using High‐Speed Experimentation
Authors: Pescarmona Paolo P. , van der Waal Jan C. , Maschmeyer Thomas
Published: March 2004

A set of new titanium‐silsesquioxane epoxidation catalysts was discovered by exploring the hydrolytic condensation of a series of trichlorosilanes in highly polar solvents by means of high‐speed experimentation techniques. The most promising silsesquioxane leads were prepared on a conventional laboratory scale and fully characterised. The lead generated by the hydrolytic condensation of tBuSiCl3 in DMSO consisted of a set of incompletely condensed silsesquioxane structures, whereas that obtained from the hydrolytic condensation of tBuSiCl3 in water consisted of a single silsesquioxane structure, tBu2Si2O(OH)4. This is the first reported example of the use of this silsesquioxane as a precursor for active Ti catalysts. The Ti complexes prepared with tBu2Si2O(OH)4 were supported on silica to produce active heterogeneous epoxidation catalysts.

Trioxaquines are dual molecules that contain a trioxane motif linked to an aminoquinoline entity. Among the different compounds of this series, trioxaquine cis‐15 (DU1302 c), prepared from α‐terpinene, a cheap natural product, showed efficient antimalarial activity in vitro on both sensitive and resistant strains of Plasmodium falciparum (IC50=5–19 nM). A stereochemical description of this stable, nontoxic, and non‐genotoxic antimalarial agent is detailed. Mice infected with P. vinckei were successfully treated with cis‐15 in a four‐day suppressive test. The doses required to decrease parasitemia by 50 % (ED50) were 5 and 18 mg kg−1 d−1 after intraperitoneal and oral administration, respectively. Parasitemia clearance was complete without recrudescence at an intraperitoneal dose of 20 mg kg−1 d−1.
Probing Ionic Association on Metal Oxide Clusters by Pulsed Field Gradient NMR Spectroscopy: The Example of Sn12–Oxo Clusters
Authors: Ribot François , Escax Virginie , Martins José C. , Biesemans Monique , Ghys Laurent , Verbruggen Ingrid , Willem Rudolph
Published: March 2004

Pulsed field gradient 1H NMR spectroscopy has been applied to investigate the association behavior of the Sn12–oxo cluster macrocation [(BuSn)12O14(OH)6]2+ with two different and smaller anions, p‐toluenesulfonate (PTS−) and diphenylphosphinate (Ph2PO2−). By monitoring the translational diffusion coefficients of the various species involved, it is shown that the association depends on the anion involved and on the solvent used. Moreover, the possibility to individually monitor the diffusion characteristics of multiple anionic and cationic species in mixtures, by virtue of resolved 1H resonances available from each species, allows us to evidence the occurrence of ion exchange in such systems. Thus when [(BuSn)12O14(OH)6](PTS)2 is mixed with two equivalents of Ph2PO2NMe4, PTS− is displaced by Ph2PO2−, highlighting the greater affinity of the organotin macrocation for the diphenylphosphinate. This example clearly illustrates the potential of pulsed field gradient 1H NMR spectroscopy in inorganic/organometallic chemistry, to follow preferential ion pairing in multi‐ion systems at the level of each individually charged species.
