In the course of studies on hybrid antibacterials incorporating 2-aryl-5-nitro-1Hindolemoieties as potential bacterial NorA efflux pump inhibitors, the compound 1-[2-(5-nitro-1H-indol-2-yl)phenyl]methylpyridinium chloride (2) was synthesized and structurallycharacterized. This pyridinium chloride salt crystallized in the monoclinic space groupP21/c with the following unit cell dimensions: a 10.274(3) A, b 13.101(4) A, c 13.439(4)A, B 107.702(7)deg, V 1723.2(9) A3, Z (f.u.) = 4; R1 = 0.048, and wR2 = 0.13. Of interest inthe single crystal X-ray structure is the (intramolecular) disposition of the pyridinium planeover the indole heterocyclic residue [interplanar dihedral angle 17.91(4)deg].

One-year-old olive (Olea europaea L. cv. Gemlik) seedlings were exposed to increasing levels of salinity in pot culture. The experiment was laid out in a randomized block design with 6 replicates. Dry matter (DM) percentage, sodium (Na) and chloride (Cl) concentrations, 1,1-diphenyl-2-picryl hydrazyl (DPPH) scavenging activity, reducing power (RP), total phenolic content (TPC), and proline (PRO) content were determined in the leaves of the plants. The results showed that the olive plant used physiological and biochemical mechanisms consecutively to alleviate the effects of salt stress. The type of mechanism used was related to the severity of the salt stress. Salinity-induced …
