1.Crystal structure of cis-bis-{4-phenyl-1-[(3R)-1,7,7-tri-methyl-2-oxobi-cyclo-[2.2.1]heptan-3-ylidene]thio-semicarbazidato-κ(3) O,N (1),S}cadmium(II) with an unknown solvent mol-ecule.
Nogueira VS1, Bresolin L1, Näther C2, Jess I2, de Oliveira AB3. Acta Crystallogr E Crystallogr Commun. 2015 Nov 21;71(Pt 12):m234-5. doi: 10.1107/S2056989015021428. eCollection 2015.
The reaction between the racemic mixture of the camphor-4-phenyl-thio-semicarbazone derivative and cadmium acetate dihydrate yielded the title compound, [Cd(C17H20N3OS)2]. The Cd(II) ion is six-coordinated in a distorted octa-hedral environment by two deprotonated thio-semicarbazone ligands acting as an O,N,S-donor in a tridentate chelating mode, forming five-membered chelate rings. In the crystal, the mol-ecules are connected via pairs of N-H⋯S and C-H⋯S inter-actions, building centrosymmetric dimers. One of the ligands is disordered in the campher unit over two sets of sites with site-occupancy factors of 0.7 and 0.3. The structure contains additional solvent mol-ecules, which are disordered and for which no reasonable split model was found. Therefore, the data were corrected for disordered solvent using the SQUEEZE routine [Spek (2015 ▸). Acta Cryst. C71, 9-18] in PLATON. Since the disordered solvents were removed by data processing, and the number of solvent entities was a suggestion only, they were not considered in the chemical formula and subsequent chemical or crystal information.
2.Wetting Camphor: Multi-Isotopic Substitution Identifies the Complementary Roles of Hydrogen Bonding and Dispersive Forces.
Pérez C1,2, Krin A1,2, Steber AL1,2,3, López JC1,4, Kisiel Z5, Schnell M1,2,3. J Phys Chem Lett. 2016 Jan 7;7(1):154-60. doi: 10.1021/acs.jpclett.5b02541. Epub 2015 Dec 24.
Using broadband rotational spectroscopy, we report here on the delicate interplay between hydrogen bonds and dispersive forces when an unprecedentedly large organic molecule (camphor, C10H16O) is microsolvated with up to three molecules of water. Unambiguous assignment was achieved by performing multi H2(18)O isotopic substitution of clustered water molecules. The observation of all possible mono- and multi-H2(18)O insertions in the cluster structure yielded accurate structural information that is not otherwise achievable with single-substitution experiments. The observed clusters exhibit water chains starting with a strong hydrogen bond to the C═O group and terminated by a mainly van der Waals (dispersive) contact to one of the available sites at the monomer moiety. The effect of hydrogen bond cooperativity is noticeable, and the O···O distances between the clustered water subunits decrease with the number of attached water molecules. The results reported here will further contribute to reveal the hydrophobic and hydrophilic interactions in systems of increasing size.
3.Chemical Variability of the Essential Oil Isolated from Aerial Parts of Tetraclinis articulata from North-Western Algeria.
Boussaïd M, Bekhechi C, Beddou F, Sari DC, Bighelli A, Casanova J, Tomi F. Nat Prod Commun. 2015 Aug;10(8):1447-52.
The objective was to investigate the yield and chemical composition of 50 essential oil samples isolated from leaves and flowers of Tetraclinis articulata harvested in eight locations (coastal township and highlands) of Tlemcen Province (North-Western Algeria). Essential oil yields varied drastically from sample to sample (0.03 to 0.86%, w/w). No direct correlation was observed between the yield and the altitude of the harvest areas. The oils consisted mainly of monoterpenes: α-pinene (9.2-56.5%), bornyl acetate (1.2-45.1%), camphor (0.5-40.3%), borneol (0.2-12.9%), limonene (3.6-12.5%), and myrcene (1.6-9.7%). Sesquiterpenes were represented by germacrene D (up to 14.2%) and (E)-β-caryophyllene (up to 13.3%). PCA analysis of the data allowed the distinction of two groups within the samples. The composition of group I (9 samples) was dominated by camphor, (Mean = 30.9%) followed by α-pinene (M = 19.1%) and bornyl acetate (M = 11.4%). Group II was divided into two sub-groups.
4.Chemical Composition and Antipathogenic Activity of Artemisia annua Essential Oil from Romania.
Marinas IC1, Oprea E2, Chifiriuc MC1, Badea IA3, Buleandra M3, Lazar V1. Chem Biodivers. 2015 Oct;12(10):1554-64. doi: 10.1002/cbdv.201400340.
The essential oil extracted by hydrodistillation from Romanian Artemisia annua aerial parts was characterized by GC/MS analysis, which allowed the identification of 94.64% of the total oil composition. The main components were camphor (17.74%), α-pinene (9.66%), germacrene D (7.55%), 1,8-cineole (7.24%), trans-β-caryophyllene (7.02%), and artemisia ketone (6.26%). The antimicrobial activity of this essential oil was evaluated by determining the following parameters: minimal inhibitory concentration (MIC), minimal bactericidal concentration (MBC), minimal fungicidal concentration (MFC), and minimal biofilm eradication concentration (MBEC). Moreover, the soluble virulence factors were quantified with different biochemical substrates incorporated in the culture media. The reference and resistant, clinical strains proved to be susceptible to the A. annua oil, with MICs ranging from 0.51 to 16.33 mg/ml. The tested essential oil also showed good antibiofilm activity, inhibiting both the initial stage of the microbial cell adhesion to the inert substratum and the preformed mature biofilm.
