Whole-mol-ecule disordered (E)-2-(1-hy-droxy-3-phenylprop-2-en-1-yl-idene)-4,5-dimeth-oxycyclo-pent-4-ene-1,3-dione isolated from Lindera oxyphylla (Lauraceae).

ABSTRACT: In the mol-ecule of the title compound, C(16)H(14)O(5), all non-H atoms are approximately co-planar [maximum atomic deviation = 0.064?(5)?Å]. The hy-droxy group is a hydrogen-bond donor to a carbonyl O atom. Weak intermolecular C-H?O hydrogen bonding is present in the crystal structure. The crystal structure is 'whole-mol-ecule disordered' about an axis that runs approximately along the length of the mol-ecule; the occupancy of the two disorder components was set as exactly 0.5. An intra-molecular O--H?O hydrogen bond exists in each component.

A triclinic polymorph of (E)-2-(1-hy-droxy-3-phenyl-prop-2-en-1-yl-idene)-4,5-dimeth-oxy-cyclo-pent-4-ene-1,3-dione.

Project description:The title compound, C(16)H(14)O(5), is a triclinic polymorph of a previously reported monoclinic structure [Hosseinzadeh et al. (2011 ?). Acta Cryst. E67, o1544]. The mol-ecule is roughly planar, the r.m.s. deviation from the least-squares plane of all non-H atoms being 0.092?Å. In the crystal, adjacent mol-ecules are linked through C-H?O hydrogen bonds into an infinite two-dimensional network parallel to (011). The layers are further connected via C-H?? inter-actions, forming a three-dimensional structure. Intra-molecular O-H?O and C-H?O hydrogen bonds are also observed.

1,5-Bis(penta-fluoro-phen-yl)-3-phenyl-pent-2-ene-1,5-dione.

Project description:In the title compound, C(23)H(8)F(10)O(2), the three arene rings are twisted one with respect to the other: the two perfluorinated arene rings are tilted to each other by an angle of 60.39?(7)°. They are inclined to the non-fluorinated phenyl unit by 38.85?(7) and 78.74?(7)°. The olefinic double bond adopts an E configuration. The carbonyl groups are not in a coplanar alignment with reference to the neighbouring arene rings. The crystal packing features a number of weak C-H?F inter-actions, which leads to the formation of a three-dimensional network.

6-Isopropyl-3-phenyl-5-(p-tol-yloxy)-3H-1,2,3-triazolo[4,5-d]pyrimidin-7(6H)-one: whole-mol-ecule disorder.

Project description:The title compound, C(20)H(19)N(5)O(2), exhibits whole-mol-ecule disorder the refined ratios of the two components being 0.57?(2):0.43?(2). In the major component, the essentially planar [maximum deviation 0.033?(17)?Å] fused pyrimidine and triazole ring system forms a dihedral angle of 10.5?(3)° with the phenyl ring, while in the minor component of disorder this angle is 27.5?(5)°. The crystal structure is stabilized by ?-? stacking inter-actions between symmetry-related triazole and pyrimidine rings, with centroid-centroid distances of 3.594?(10)?Å.

Comparative chloroplast genomics and phylogenetics of nine Lindera species (Lauraceae).

Project description:Lindera, a core genus of the Lauraceae family, has important economic uses in eastern Asia and North America. However, its historical diversification has not been clarified. In this study, we report nine newly sequenced Lindera plastomes. The plastomes of these nine Lindera species range from 152,211 (L. nacusua) to 152,968?bp (L. metcalfiana) in length, similar to that of another Lauraceae species, Litsea glutinosa (152,618?bp). The length variation of these plastomes derived from the length variation in the loci ycf1, ycf2, ?ycf1, and ndhF-?ycf1. Comparing our sequences with other available plastomes in the Lauraceae indicated that eight hypervariable loci, ihbA-trnG, ndhA, ndhF-rpl32, petA-psbJ, psbK-psbI, rps16, trnS-trnG, and ycf1, could serve as DNA barcodes for species delineation, and that the inverted repeats (IRs) showed contraction/expansion. Further phylogenetic analyses were performed using 32 complete plastomes of Lauraceae and seven barcodes from 14 additional species of Lindera and related species in the core Lauraceae. The results showed that these Lindera species grouped into two or four sub-clades, and that two Litsea species and Laurus nobilis were located in the same sub-clade as five Lindera species. These data support a close relationship between the genera Laurus, Lindera, and Litsea, and suggest that Lindera is polyphyletic.

Development and characterization of microsatellite loci for Lindera glauca (Lauraceae).

Project description:PREMISE OF THE STUDY:Microsatellite primers were developed to investigate population genetic structure in Lindera glauca (Lauraceae). METHODS AND RESULTS:Twenty-five microsatellite primers were developed and optimized for L. glauca using Illumina's Solexa sequencing technology. These novel primers were found to be polymorphic in nine wild L. glauca populations with 81 total alleles confirmed and genotyped via capillary gel electrophoresis. The total number of alleles, observed heterozygosity, and expected heterozygosity for each population ranged from one to four, from 0.00 to 0.90, and from 0.00 to 0.79, respectively. In addition, the 25 primers were tested in 10 additional individuals of the related species L. communis, and all but four markers showed good amplification results. CONCLUSIONS:This set of microsatellite primers is the first specifically developed for L. glauca and will facilitate studies of genetic diversity and evolution among populations of this species.

3,3'-Dimeth-oxy-2,2'-[(4,5-dimethyl-o-phenyl-ene)bis-(nitrilo-methanylyl-idene)]diphenol.

Project description:The asymmetric unit of the title compound, C(24)H(24)N(2)O(4), comprises two crystallographically independent mol-ecules A and B. The dihedral angles between the central dimethyl-substituted benzene ring and the two outer benzene rings are 49.5?(1) and 5.06?(11)° in mol-ecule A, and 42.55?(8) and 5.77?(9)° in mol-ecule B. In each mol-ecule, two strong intra-molecular O-H?N hydrogen bonds generate two S(6) ring motifs. The crystal structure is further stabilized by inter-molecular ?-? [centroid-centroid distances of 3.591?(1)-3.876?(1)?Å] inter-actions.

Development of 20 chloroplast microsatellite primers in wuyao (Lindera aggregata, Lauraceae).

Project description:Premise of the Study:To investigate the population genetics and evolutionary history of wuyao (Lindera aggregata, Lauraceae) and other Lindera species, polymorphic chloroplast microsatellite (cpSSR) primers were developed. Methods and Results:The complete chloroplast genome of L. glauca was used to design 74 primers for L. aggregata. Agarose gel electrophoresis and Sanger sequencing were used to select 20 polymorphic primers. These primers were then tested in 70 individuals from three populations of L. aggregata. The number of alleles ranged from two to four, and the unbiased haploid diversity index ranged from 0.457 to 0.685. Up to 17 primers successfully amplified in four other Lindera species: L. prattii, L. chunii, L. lungshengensis, and L. pulcherrima var. hemsleyana. Conclusions:The 20 primers reported here can potentially be used for future genetic studies of L. aggregata and other Lindera species.

4-(Dimethyl-amino)pyridinium tribromide: whole mol-ecule disorder of cation and anion.

Project description:In the title salt, C(7)H(11)N(2) (+)·Br(3) (-), the cation and the near-linear anion [Br-Br-Br = 179.41?(8)°] both show whole-mol-ecule disorder about crystallographic twofold rotation axes. The cation is weakly hydrogen-bonded to the anion by an N-H?Br inter-action. The crystal studied was found to be a racemic twin, with a twin component of nearly 50%.

Crystal structure analysis of the biologically active drug mol-ecule riluzole and riluzolium chloride.

Project description:This study is an investigation into the crystal structure of the biologically active drug mol-ecule riluzole [RZ, 6-(tri-fluoro-meth-oxy)-1,3-benzo-thia-zol-2-amine], C8H5F3N2OS, and its derivative, the riluzolium chloride salt [RZHCl, 2-amino-6-(tri-fluoro-meth-oxy)-1,3-benzo-thia-zol-3-ium chloride], C8H6F3N2OS+·Cl-. In spite of repeated efforts to crystallize the drug, its crystal structure has not been reported to date, hence the current study provides a method for obtaining crystals of both riluzole and its corresponding salt, riluzolium hydro-chloride. The salt was obtained by grinding HCl with the drug and crystallizing the obtained solid from di-chloro-methane. The crystals of riluzole were obtained in the presence of l-glutamic acid and d-glutamic acid in separate experiments. In the crystal structure of RZHCl, the -OCF3 moiety is perpendicular to the mol-ecular plane containing the riluzolium ion, as can be seen by the torsion angle of 107.4?(3)°. In the case of riluzole, the torsion angles of the four different mol-ecules in the asymmetric unit show that in three cases the tri-fluoro-meth-oxy group is perpendicular to the riluzole mol-ecular plane and only in one mol-ecule does the -OCF3 group lie in the same mol-ecular plane. The crystal structure of riluzole primarily consists of strong N-H?N hydrogen bonds along with weak C-H?F, C-H?S, F?F, C?C and C?S inter-actions, while that of its salt is stabilized by strong [N-H]+?Cl- and weak C-H?Cl-, N-H?S, C-H?F, C?C, S?N and S?Cl- inter-actions.

The complete chloroplast genome of <i>Lindera pulcherrima</i> var. <i>hemsleyana</i> (Lauraceae).

Project description:Lindera pulcherrima var. hemsleyana is an evergreen tree of the genus Lindera with important medicinal value. The complete chloroplast genome of L. pulcherrima var. hemsleyana is 152,710 bp in length, containing a LSC region of 93,751 bp, a SSC region of 18,813 bp, and a pair of inverted repeats (IRA and IRB) of 20,073 bp each. The genome encoded 128 genes, including 83 protein-coding genes, 8 ribosomal RNA genes, 36 transfer RNA genes, and one pseudogene (ycf1). Most of these genes occurred in a single copy, whereas 15 genes occurred in double copies, including all rRNA, 6 tRNA, and 5 protein-coding genes. The GC content of the whole genome, LSC, SSC, and IR regions is 39.2%, 38.0%, 33.9%, and 44.4%, respectively. A total of 90 SSRs were discovered, the numbers of mono-, di-, tri-, tetra-, penta-, and hexa-nucleotides SSRs were 66, 10, 4, 8, 1, and 1, respectively. Phylogenetic analysis of cp genomes from 24 species of Lauraceae revealed that cp genomes of L. pulcherrima var. hemsleyana, L. pulcherrima var. attenuata, and L. pulcherrima formed a monophyletic clade with 100% bootstrap value.
