The Zn-TPyP molecules align their pyridyl endgroups toward a common fourfold node, which suggests the presence of a metal–ligand interaction between Fe atoms (bright spots in Figure 3c) and pyridyl ...

We have investigated the synthesis of a novel pyridyl-substituted indenyl trinuclear ruthenium complex, {μ2-η5:η1-(C5H4N)(C9H5)}Ru3(CO)9 (1), and its reactivities with pyridine derivatives, PPh3, and ...

RESULTS AND DISCUSSION Chemistry. Final compounds listed in Table I were synthesized using the sequence of reactions depicted in Figure 1.In the first step, compound I derivatives were prepared via ...

作用机理 ：Desamino (D - 3 - (3′ - Pyridyl) - Ala2,Arg8) - Vasopressin 作为一种加压素类似物，其作用机理与天然加压素类似，但又有其独特之处。 它主要通过与肾脏集合管上皮细胞上的 V2 受体结合，激活腺苷酸环化酶，使细胞内 cAMP 水平升高，进而激活蛋白激酶 A（PKA）。

In conclusion, this study highlights the potential of a novel 4-pyridyl analog of SLC-0111 (Pyr) as a promising candidate for cancer therapy. Pyr exhibited selective cytotoxicity against various ...

The ligand di-2-pyridyl ketone benzoylhydrazone (DPKBH) is widely used for the determination of transition metal ions in environmental samples. Due to its low solubility in water it is used in aqueous ...

In this paper, we have studied the photoinduced changes of meso-substituted cationic pyridyl porphyrins in the presence of folic acid using fluorescence and absorption spectroscopy. In this work, it ...

ABSTRACT: A new spectrofluorimetric reagent 2-(α-pyridyl)-thioquinaldinamide (PTQA) has been synthesized and characterized through novel reaction techniques. A very simple, ultra-sensitive and highly ...
