Abstract:
Lead tetraacetate oxidation of phenanthrene-4,5-dicarboxylic acid in acetonitrile with pyridine affords 5-hydroxyphenanthrene-4-carboxylic acid as its lactone , which can be methylated as the sodium salt, giving 5-methoxyphenanthrene-4-carboxylic acid, albeit in poor yield. New spectroscopic evidence (particularly 13C n.m.r.) confirms that 5-formylphenanthrene-4-carboxylic acid, which is an intermediate in the synthesis, exists as the lactol , 4-hydroxyphenanthro[4,5-cdeloxepin-G(4H)-one.

Introduction: Motor-function modulation through Pyridine-3-carboxylic acid was assessed against. Haloperidol induced Parkinson’s disease (PD) in albino-mice. The objectives of this study were to test the effect of Haloperidol in development of PD, effectiveness of Pyridine-3-carboxylic acid in mice and evaluation of the motor-function changes in mice before and after treatment.
 Methods: The study was divided into 3 phases: During Phase-I (randomization), all the subjects were randomly divided into 4 groups and trained for wire-hanging, grip strength, vertical rod and swim tests for 1 wee

Abstract:
The title compound [systematic name: 5-(trifluoromethyl)pyridine-2-carboxylic acid monohydrate], C7H4F3NO2·H2O, is the acid hydrate of a pyridine with a carboxylic acid group and a trifluoromethyl substituent situated para to one another on the aromatic ring. The molecule forms a centrosymmetric water-bridged hydrogen-bonding dimer with graph-set notation R 4 4 (12). Hydrogen-bonding distances of 2.5219 (11) and 2.8213 (11) Å are observed between the donor carboxylic acid and the bridging water acceptor, and the donor water and carbonyl oxygen acceptor, respectively. The dimers are further lin

Abstract:
In the title salt, C12H11N2O2+·C7H5O6S−, the dihedral angle between the benzene and pyridine rings in the 4-(4-nitrobenzyl)pyridinium cation is 82.7 (2)°. Within the anion there is an intramolecular hydroxy-O—H...O(carboxylic acid) bond. In the crystal, the cation forms a single N+—H...Osulfonatehydrogen bond with the anion. These cation–anion pairs interact through duplex anion carboxylic acid O—H...Osulfonatehydrogen bonds, giving a centrosymmetric cyclic association [graph setR22(16)]. The crystals studied were non-merohedrally twinned.

A series of tetranuclear grid-type complexes were prepared by the reaction of the asymmetric multidentate ligand HL (HL = 2-[3-(2-hydroxyphenyl)-1H-pyrazol-5-yl]-6-pyridine carboxylic acid ethylester) with different metal sources. The tetranuclear copper complex, [Cu4(L1)4(NO3)4(H2O)4]·Et2O·2MeOH (1, HL1 = 2-[3-(2-hydroxyphenyl)-1H-pyrazol-5-yl]-6-pyridine carboxylic acid methyl ester) consists of four ligands, four copper ions, four nitrate ions and four water molecules, forming a [2 × 2] grid structure, in which all four copper ions have the same coordination environment.

Abstract:
Two MOFs materials, [Ni (3,4-PBC)2(H2O)] (1) and [Co (3,4-PBC)2(H2O)] (2), [fuchsin acid and Methyl orange acid] (2), were synthesized by using pyridine carboxylic acid ligand 3-pyridin-4-benzoic acid (3,4-HPBC) as building block and transition metal Ni (II) and Co (II) as central ions. The results indicate that two types of MOFs materials and sensitized TiO2 composite materials have good photodegradation activity against two pollutants.
