Fluorometric methods for the determination of Hg(II) (80-320 ppb) and Cu(II) (0.4-1 ppb) are described. These ions catalyze the autoxidation of 2,2′-dipyridyl ketone hydrazone, which yields a product exhibiting an intense blue fluorescence in acidic solution This product was investigated and the exptl. variables and interferences in each determination were studied.

Cory, Joseph G. published the artcileSubstituted 2-acylpyridine-α-(N)-hetarylhydrazones as inhibitors of ribonucleotide reductase activity and L1210 cell growth, Quality Control of 2215-33-0, the publication is Anticancer Research (1994), 14(3A), 875-9, database is CAplus and MEDLINE.

A series of substituted 2-acylpyridine-α-(N)-hetarylhydrazones was prepared and studied for their effects on mammalian ribonucleotide reductase activity using a highly purified enzyme preparation from Ehrlich tumor cells and on mouse leukemia L1210 cell growth in culture. Pyridine-2-aldehyde-2-pyridylhydrazone (PH 22), ethyl-2-pyridylketone-1-phthalazinylhydrazone (PH 22-25) and pyridine-2-aldehyde-2′-quinolylhydrazone (PQ 22) inhibited purified ribonucleotide reductase activity and inhibited L1210 cell growth in culture. PH 22-25 inhibited [³H]thymidine incorporation into DNA and inhibited ribonucleotide reductase activity in situ (as measured by [¹⁴C]cytidine metabolism) and as a result inhibited DNA synthesis. There was no effect on RNA synthesis. These data indicate that these substituted hydrazones are potent inhibitors of tumor cell growth through the inhibition of ribonucleotide reductase.

Dunn, J. G. published the artcileBidentate nature of 2-pyridinecarboxaldehyde 2-pyridylhydrazone in its complexes with metal carbonyls, Formula: C11H10N4, the publication is Inorganic and Nuclear Chemistry Letters (1969), 5(7), 539-43, database is CAplus.

Substituted metal carbonyls in which the title compound (paphy) (I) is acting as a bidentate donor have been prepared The compounds prepared were Cr(CO)4(paphy), Mo(CO)4(paphy), and W(CO)4-(paphy). Mo(CO)6 (0.2 g.) was refluxed with 0.15 g. I in 5 ml. Me2C(OMe)2 (II) for 30 min. under N. The solution colored to a maroon-purple. After 30 min. the solution was filtered hot and the solid product washed with II. The product was stable under normal laboratory conditions. Similarity in the CO stretching frequencies between the I compounds and the bipyridine complex Mo(cO)4(bipy) is evidence of the bidentate nature of the I ligand. Further evidence is the fact that the complexes are diamagnetic and nonelectrolytes in EtCN and MeNO2. Mo-(CO)4(paphy) reacts with (C6H5)3P to produce cis-Mo(CO)3-(paphy)(PPh3); ir CO stretching frequencies are quite similar to the analogous bipyridine complex.

Gueye, Mbosse Ndiaye published the artcileLanthanide(III) complexes with tridentate schiff base ligand, antioxidant activity and X-ray crystal structures of the Nd(III) and Sm(III) complexes, Application In Synthesis of 2215-33-0, the publication is South African Journal of Chemistry (2017), 70(1), 8-15, S1-S6, database is CAplus.

The tridentate N4-type Schiff base was synthesized from the condensation reaction of 2-hydrazinopyridine and pyridine-2-carbaldehyde. Neodymium and samarium complexes were isolated when the corresponding nitrate salt was added to the solution of the ligand. The isolated compounds were characterized by elemental analyses, IR study, room temperature magnetic measurements and single x-ray crystal diffraction of the two crystals. Both complexes crystallize in the monoclinic system with space group P21/c. The cell parameters of the Nd complex are a 11.0927(8), b 17.9926(13) Å, c 11.9395(9) Åand β 115.274(5)° while the Sm complex shows parameters cell of a 11.0477(8), b 17.9254(13), c 11.9149(8) Å and β 115.489(5)°. The x-ray study reveals isotopic Nd/Sm binuclear structures were each metal ion is nine-coordinated in the same fashion. Both metal centers have distorted tricapped trigonal prism geometry, with the Schiff base acting as tridentate ligand. The DPPH• radical scavenging effects of the Schiff base ligand and its Ln(III) complexes were screened. The Ln(III) complexes were significantly more efficient in quenching DPPH• than the free Schiff base ligand.

Hydrazones and oximes are widely useful structures for conjugate formation in chem. and biol., but their formation can be slow at neutral pH. Kinetics studies were performed for a range of structurally varied hydrazines, and a surprisingly large variation in reaction rate was observed Structures that undergo especially rapid reactions were identified, enabling reaction rates that rival orthogonal cycloaddition-based conjugation chemistries.
