Authors: Lenda Fatimazohra , Guenoun Farhate , Tazi Bouchra , Ben larbi Najib , Allouchi Hassan , Martinez Jean , Lamaty Frédéric
Published: January 2005

Racemic 5‐aryl‐ and 5‐(arylmethyl)tetrazolyl‐substituted pyroaminoadipic and pipecolic acid derivatives were diastereoselectively synthesized from dimethyl meso‐2,5‐dibromoadipate (1) in good yields under mild reaction conditions. The key step of this reaction sequence is the selective N2‐alkylation of 5‐substituted tetrazoles with 1. The reactive 2‐bromo‐5‐tetrazolyladipate derivatives 2a−g were generated and treated with sodium azide, followed by Pd/C‐catalyzed hydrogenation, to provide lactams 4a−g. The chemoselective reduction of the amide carbonyl group of 4a−g with BH3, followed by acid hydrolysis, provided 5‐tetrazolylpipecolic acids in racemic form. (© Wiley‐VCH Verlag GmbH & Co.

Isolation, Structural Elucidation, and Synthesis of Curcutetraol
Authors: Mülhaupt Tanja , Kaspar Hannelore , Otto Sabine , Reichert Matthias , Bringmann Gerhard , Lindel Thomas
Published: January 2005

The new natural products (+)‐curcutetraol and (−)‐curcutriolamide were isolated from the bacterium CNH‐741 and the fungus CNC‐979, isolated from marine sediment. (+)‐Curcutetraol is a polar compound and contains a tertiary benzylic alcohol moiety at the single stereogenic center, which was retained without racemization by avoiding chromatography on silica. The absolute configuration of (+)‐curcutetraol was determined by comparison of its experimental CD spectrum with the spectra predicted by quantum‐chemical CD calculations. Phenolic bisabolane sesquiterpenoids from marine sources were previously known only from gorgonians and sponges. A short total synthesis of racemic curcutetraol has been developed.

Palladium‐Catalysed Amination of 1,8‐ and 1,5‐Dichloroanthracenes and 1,8‐ and 1,5‐Dichloroanthraquinones
Authors: Beletskaya Irina P. , Bessmertnykh Alla G. , Averin Alexei D. , Denat Franck , Guilard Roger
Published: January 2005

Diamino derivatives of anthracene and anthraquinone have been synthesised by palladium‐catalysed coupling of 1,8‐dichloroanthracene and 1,8‐dichloroanthraquinone with a wide range of aliphatic and aromatic primary and secondary amines. The use of polyamines gave rise to a large number of new nitrogen‐ and oxygen‐containing macrocycles incorporating anthracene or anthraquinone moieties. The method has also been employed for the preparation of bismacrocycles in which two cyclam or azacrown units are linked together by an anthracene bridge through C(sp2)−N bonds.

Vesparioside from the Marine Sponge Spheciospongia vesparia, the First Diglycosylceramide with a Pentose Sugar Residue
Authors: Costantino Valeria , Fattorusso Ernesto , Imperatore Concetta , Mangoni Alfonso
Published: January 2005

The marine sponge Spheciospongia vesparia produces vesparioside (1a), a diglycosylated glycosphingolipid which is the first example of a natural diglycosylceramide with a pentose sugar residue. The structure of vesparioside was mostly determined by extensive spectroscopic analysis but determination of the nature of the alkyl chains and elucidation of the absolute stereochemistry of the sugars and of the ceramide required chemical degradation. In this respect, an improved and simplified procedure for the microscale chemical degradation of glycosphingolipids was employed here for the first time. (© Wiley‐VCH Verlag GmbH & Co.

Total Synthesis of Cryptophycin 3
Authors: Danner Paulami , Bauer Matthias , Phukan Prodeep , Maier Martin E.
Published: January 2005

The depsipeptide cryptophycin 3 (5) and the cryptophycin analogue 43 were prepared from the corresponding four subunits. The tripeptide analogue 34 was acquired from the starting amino ester 33, which contains fragments D and C. After extension at the carboxyl function by esterification with the hydroxy ester 10, the seco compounds 37 and 42 were obtained. Ring closure was achieved by macrolactamization in the presence of TBTU as condensing agent. This work features a streamlined synthesis of the hydroxy ester 10, a short synthesis of the amino acid 14 by enantioselective alkylation of the glycinimine 21, and the use of the Fmoc protecting group for the amino functions.

Pseudorotaxanes and Rotaxanes Incorporating Diarylcycloheptatriene Stations
Authors: Abraham Werner , Grubert Lutz , Schmidt‐Schäffer Sebastian , Buck Karin
Published: January 2005

The nature of the interaction between the tetracationic cyclophane cyclobis(paraquat‐4,4′‐biphenylene) and molecular threads incorporating arylcycloheptatriene units as stations was studied through the differences between the proton resonances observed in the NMR spectra of free molecular threads and in those of corresponding pseudorotaxanes and rotaxanes (CIS values). Molecular threads of different lengths possessing one or two recognition stations and incorporating two different isomeric arylcycloheptatriene units were used for pseudorotaxanes and rotaxanes. The main contribution to the driving forces behind the complexation of pseudorotaxanes and the co‐conformation of rotaxanes was deduced from the CIS values of distinct parts of the molecular threads. The unusual signal dispersion of the cyclophane proton resonances is attributed to the asymmetry caused by the molecular thread incorporating the asymmetric cycloheptatriene ring.

Impact of transforming viruses on cellular mutagenesis, genome stability, and cellular transformation
Authors: Gatza Michael L. , Chandhasin Chandtip , Ducu Razvan I. , Marriott Susan J.
Published: January 2005

It is estimated that 15% of all cancers are etiologically linked to viral infection. Specific cancers including adult T‐cell leukemia, hepatocellular carcinoma, and uterine cervical cancer are associated with infection by human T‐cell leukemia virus type I, hepatitis B virus, and high‐risk human papilloma virus, respectively. In these cancers, genomic instability, a hallmark of multistep cancers, has been explicitly linked to the expression of oncoproteins encoded by these viruses. This review discusses mechanisms utilized by these viral oncoproteins, Tax, HBx, and E6/E7, to mediate genomic instability and cellular transformation. Environ. Mol.

Mechanistic data and cancer risk assessment: The need for quantitative molecular endpoints
Authors: Preston R. Julian
Published: January 2005

The cancer risk assessment process as currently proposed by the U.S. Environmental Protection Agency allows for the use of mechanistic data to inform the low‐dose tumor response in humans and in laboratory animals. The aim is to reduce the reliance on defaults that introduce a relatively high level of uncertainty to the risk estimates. The types of data required for this purpose are those that help identify key events in tumor formation following exposure to environmental chemicals. Informative biomarkers of tumor responses could then be developed for describing the shape of a dose‐response curve at low doses (i.e., a qualitative assessment) and for predicting tumor frequency at these low doses (i.e., a quantitative assessment). A number of recently developed molecular approaches could aid in the development of qualitatively and quantitatively informative biomarkers. An overview of these with examples of their use is presented. These methods include quantitative gene expression array techniques, quantitative proteomic assays, and the assessment of DNA alterations at the single gene level and at the genome level of detection. It is most likely that a combination of approaches at different levels of cellular organization (i.e., DNA, RNA, and protein) will be the most productive for biomarker development. The rapid progress that is being made will make this tool kit even more applicable for the cancer risk assessment process. Environ. Mol. Mutagen., 2005. Published 2005 Wiley‐Liss, Inc.
Components of nucleotide excision repair and DNA damage tolerance in Arabidopsis thaliana
Authors: Kunz Bernard A. , Anderson Heather J. , Osmond Megan J. , Vonarx Edward J.
Published: January 2005

As obligate phototrophs, and despite shielding strategies, plants sustain DNA damage caused by UV radiation in sunlight. By inhibiting DNA replication and transcription, such damage may contribute to the detrimental effects of UV radiation on the growth, productivity, and genetic stability of higher plants. However, there is evidence that plants can reverse UV‐induced DNA damage by photoreactivation or remove it via nucleotide excision repair. In addition, plants may have mechanisms for tolerating UV photoproducts as a means of avoiding replicative arrest. Recently, phenotypic characterization of plant mutants, functional complementation studies, and cDNA analysis have implicated genes isolated from the model plant Arabidopsis thaliana in nucleotide excision repair or tolerance of UV‐induced DNA damage. Here, we briefly review features of these processes in human cells, collate information on Arabidopsis homologs of the relevant genes, and summarize the experimental findings that link certain of these plant genes to nucleotide excision repair or damage tolerance.

Loss of chromosome arm 18q is a common event in human pancreatic, colon, and breast cancers and is often interpreted as representing loss of one or more tumor‐suppressor genes. In this article, we describe two novel biallelic deletions at chromosome band 18q21.1 in a recently characterized human breast cancer cell line, HCC‐1428. One lesion deletes a fragment of approximately 300 kb between SMAD4 and DCC that encodes no known genes. The second lesion is an in‐frame SMAD4 deletion (amino acids 49–51) that affects the level of SMAD4 protein but not the SMAD4 message. This change accelerates 26S proteasome–mediated degradation of both endogenous and exogenous mutant SMAD4. Examination of normal DNA from the same patient demonstrated that both lesions are somatic and associated with loss of both normal alleles. These data support the concept that two independent tumor‐suppressor loci exist at chromosome segment 18q21.1, one at SMAD4 and the other potentially at an enhancer of DCC or an unrelated novel gene. © 2005 Wiley‐Liss, Inc.

To assess the prevalence of mutations in the CEBPA gene, which encodes the myeloid transcription factor CEBPA in specific cytogenetic subgroups, we initially studied 125 patients with acute myeloid leukemia (AML). Five of the eight patients with del(9q) as the sole aberration or in combination with a single additional abnormality other than t(8;21) had CEBPA mutations associated with loss of CEBPA function. Consequently, 41 additional del(9q) cases were analyzed; nine had CEBPA loss‐of‐function mutations. The overall prevalence of CEBPA loss‐of‐function mutations in cases with del(9q) in a noncomplex karyotype was 41% (14 of 34 patients), whereas none of the patients who had a del(9q) in a complex karyotype (n = 7) or together with a t(8;21) (n = 10) demonstrated mutant CEBPA. We have shown for the first time that AML with del(9q) in the context of a noncomplex karyotype is strongly associated with CEBPA loss‐of‐function mutations. Loss of a critical segment of 9q, most likely in 9q22, and disruption of CEBPA function possibly cooperate in the pathogenesis of del(9q) AML. © 2005 Wiley‐Liss, Inc.
