Desoxyhemigossypol 6-methyl ether.

ABSTRACT: THE TITLE SESQUITERPENE [SYSTEMATIC NAME: 6-methoxy-10-methyl-7-(propan-2-yl)-2-oxatricyclo[6.3.1.0(4,12)]dodeca-1(11),4,6,8(12),9-pentaen-5-ol], C(16)H(18)O(3), was isolated from pathogen-infected stele tissue of Gossypium barbadense. There are two mol-ecules in the asymmetric unit and the dihedral angle between their naphtho-furan systems is 86.48?(2)°. In the crystal, O-H?O hydrogen bonds between the hy-droxy groups and etheric O atoms link the mol-ecules into centrosymmetric tetra-mers. These tetra-mers are assembled into (010) layers via stacking inter-actions between the naphtho-furan systems [inter-planar distance 3.473?(3)?Å] and short C-H?O contacts.

Alternariol 9-O-methyl ether.

Project description:The title compound (AME; systematic name: 3,7-dihy-droxy-9-meth-oxy-1-methyl-6H-benzo[c]chromen-6-one), C(15)H(12)O(5), was isolated from an endophytic fungi Alternaria sp., from Catharanthus roseus (common name: Madagascar periwinkle). There is an intramolecular O-H?O hydrogen bond in the essentially planar mol-ecule (r.m.s. deviation 0.02?Å). In the crystal, the molecule forms an O-H?O hydrogen bond with its centrosymmetric counterpart with four bridging inter-actions (two O-H?O and two C-H?O). The almost planar sheets of the dimeric units thus formed are stacked along b axis via C-H?? and ?-? contacts [with C?C short contacts between aromatic moieties of 3.324?(3), 3.296?(3) and 3.374?(3)?Å].

Semisynthetic roxburghin tetra-methyl ether.

Project description:The title mol-ecule, (E)-2,3',4,5-tetra-methoxy-stilbene, C(18)H(20)O(4), is virtually planar. The angle between the two benzene rings is 4.06?(6)°. The inter-molecular inter-actions present in the structure are weak. There are C-H?O hydrogen bonds and C-H??-electron ring inter-actions. The mol-ecules are ordered into planes that are parallel to (01). The distance between adjacent planes is about 3.3?Å and therefore ?-? electron inter-actions between the aromatic planes are also plausible.

Salvinorin B meth-oxy-methyl ether.

Project description:The title compound [MOM-SalB; systematic name: methyl (2S,4aR,6aR,7R,9S,10aS,10bR)-2-(3-fur-yl)-9-meth-oxy-meth-oxy-6a,10b-dimethyl-4,10-dioxo-2,4a,5,6,7,8,9,10a-octa-hydro-1H-benzo[f]isochromene-7-carboxyl-ate], C(23)H(30)O(8), is a deriv-ative of the ?-opioid salvinorin A with enhanced potency, selectivity, and duration of action. Superimposition of their crystal structures reveals, surprisingly, that the terminal C and O atoms of the MOM group overlap with the corresponding atoms in salvinorin A, which are separated by an additional bond. This counter-intuitive isosterism is possible because the MOM ether adopts the 'classic anomeric' conformation (gauche-gauche), tracing a helix around the planar acetate of salvinorin A. This overlap is not seen in the recently reported structure of the tetra-hydro-pyranyl ether, which is less potent. The classic anomeric conformation is strongly favoured in alk-oxy-methyl ethers, but not in substituted acetals, which may contribute to their reduced potency. This structure may prove useful in evaluating models of the activated ?-opioid receptor.

Lacinilene C 7-methyl ether.

Project description:The title compound, C16H20O3 [systematic name: 1-hy-droxy-7-meth-oxy-1,6-dimethyl-4-(propan-2-yl)naphthalen-2(1H)-one], is a sesquiterpene isolated from foliar tissues of the cotton plant and is of inter-est with respect to its anti-bacterial properties. Its phenyl ring is ideally planar, and the maximum of deviation in the second ring is 0.386?(3)?Å. The hy-droxy group and the methyl group are oriented in an equatorial fashion and axial, respectively, to the second ring. In the crystal, inversion dimers are formed through pairs of O-H?O hydrogen bonds. Weak C-H?O hydrogen bonds link the dimers into columns along the c axis. These columns form a crystal structure with a crystal packing factor of 0.66.

Alternariol 9-O-methyl ether dimethyl sulfoxide monosolvate.

Project description:The title compound (systematic name3,7-dihy-droxy-9-meth-oxy-1-methyl-6H-benzo[c]chromen-6-one dimethyl sulfoxide monosolvate), C15H12O5·C2H6OS, was isolated from an unidentified endophytic fungus (belonging to class Ascomycetes) of Taxus sp. In the crystal, both the alternariol 9-O-methyl ether (AME) and the dimethyl sulfoxide (DMSO) mol-ecules exhibit crystallographic mirror symmetry. One of the hy-droxy groups makes bifurcated hydrogen bonds, viz. an intra-molecular bond with the carbonyl group and an inter-molecular bond with the carbonyl group in an inversion-related AME mol-ecule. In the crystal, the AME mol-ecules are organized into stacks parallel with the b axis by ?-? inter-actions between centrosymmetrically related mol-ecules [the distance between the centroid of the central ring and the centroid of the meth-oxy-substituted benzene ring in the next mol-ecule of the stack is 3.6184?(5)?Å]. Pairs of DMSO mol-ecules, linked via centrosymmetric C-H?O contacts, are inserted into the voids created by the AME mol-ecules, making O-H?O and C-H?O contacts with the hosts.

Expression data from zebrafish (Danio rerio) embryos exposed to methyl tert-butyl ether

Project description:Methyl tert-butyl ether (MTBE) has been shown to target developing vasculature in piscine and mammalian model systems. In the zebrafish, MTBE induces vascular lesions throughout development. These lesions result from exposure to MTBE at an early stage in development (6-somites to Prim-5 stages). During this time period, transcript levels of vegfa, vegfc, and vegfr1 were significantly decreased in embryos exposed to 5 mM MTBE. We performed global gene analysis as an unbiased approach to discover possible modes of action of MTBE vascular toxicity. Embryos were exposed at 3 hours post fertilization (hpf) in triplicate to one of three concentrations of MTBE: 5mM (induces vascular lesions and significantly decreases vegfa), 0.625mM (NOAEL; no observed adverse effect level), and 0.00625mM (100-fold below NOAEL), or to embryo media (control). Samples were collected at 6-somites (~15hpf), 21-somites (~24 hpf), and Prim-5 (~30 hpf) stages of development. Embryos were meticulously staged at exposure and at the time of collection to maintain a homogeneous population. Our experimental design sought to explore the effect of three concentrations MTBE on three different stages of zebrafish embryonic development during the critical period established for the chemical. This time period also corresponds to an important time in the cardiovascular system develop of our model vertebrate.

Methylibium petroleiphilum PM1 exposed to the fuel-oxygenates methyl-tert-butyl ether and ethanol

Project description:Comparative transcriptome analysis of Methylibium petroleiphilum PM1 exposed to the fuel-oxygenates methyl-tert-butyl ether and ethanol High-density whole genome cDNA microarrays were used to investigate substrate-dependent gene expression of Methylibium petroleiphilum PM1, one of the best-characterized aerobic methyl tert-butyl ether (MTBE)-degrading bacteria. Differential gene expression profiling was conducted with PM1 grown on MTBE and ethanol as sole carbon sources. Based on microarray high scores and protein similarity analysis, an MTBE regulon located on the megaplasmid was identified for further investigation. Putative functions for enzymes encoded in this regulon are described with relevance to the predicted MTBE degradation pathway. A new unique dioxygenase enzyme system that carries out the hydroxylation of TBA to 2-methyl-2-hydroxy-1-propanol in M. petroleiphilum PM1 was discovered. Based on the expression data, hypotheses regarding the acquisition and evolution of MTBE genes as well as the involvement of IS elements in these complex processes were formulated. The pathways for toluene, phenol, and alkane oxidation via toluene monooxygenase, phenol hydroxylase, alkane monooxygenase as well as propane monooxygenase, respectively, were upregulated in MTBE-grown cells compared to ethanol-grown cells. Four out of nine putative cyclohexanone monooxygenases were also upregulated in MTBE-grown cells. The global transcriptome response revealed the link between metabolism of MTBE and aromatic compounds (e.g. benzene, toluene) present in gasoline mixtures. The expression data aids our understanding of the regulation of metabolic processes that may occur in response to pollutant mixtures and perturbations in the environment.
