The present investigation assessed the effects of 2-methyl-6-(phenylethynyl)-pyridine (MPEP) on acquisition and reference memory in the Morris water maze in young adult rats aged 3-month and old rats aged 26-month. MPEP reduced the swim speed of the young adult rats during acquisition, shortened the distance they covered and reduced their swim speed in the probe trial. The untreated old rats ha...

We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...

The two aromatic rings of each of the four independent molecules in the asymmetric unit of the title compound, C(11)H(9)ClN(2), are approximately coplanar; the four mol-ecules are arranged into two amino-pyridyl N-H⋯N hydrogen-bonded pairs. The structure has a 15% twin component related by a twofold rotation about [100].

In the title compound, C11H9NO2Se, the pyridine and phenyl rings are almost perpendicular, with the dihedral angle between their mean planes being 79.16 (7)°. In the crystal, the mol-ecules pack so as to form ruffled sheets in the (110) plane connected by weak C-H⋯O inter-actions. In addition, there are weak π-π inter-actions between the mean planes of both the phenyl [centroid-centroid perpend...

In the title compound, C(11)H(9)ClN, the dihedral angle between the aromatic ring planes is 44.2 (1)° and the bridging C-N-C bond angle is 127.60 (19)°. The amino N-H grouping makes a hydrogen bond to the pyridyl N atom of an adjacent mol-ecule across a center of inversion, generating a hydrogen-bonded dimer.
