4-氨基联吡啶衍生物与葫芦[6]脲形成强包合物,在荧光强度和量子产率方面表现出显着增强。显着的络合诱导的 p K a偏移 (Δp K a= 3.3)突出了结合时的强电荷-偶极相互作用。可逆绑定现象可用于设计可切换的信标,这些信标可以合并到级联的绑定网络中。该概念在本文中通过三种不同的应用得到证明:1)用于过渡金属和其他配体化学传感的可切换荧光信标;2)直接测量葫芦[6]脲与各种非荧光客体分子之间的结合常数;3) 生物催化反应的定量监测和动力学参数的测定。后一种应用通过青霉素 G 酰基转移酶催化的酰胺水解和醛缩酶抗体 38C2 催化的 β-甲酰氧基酮的消除反应来说明。

protocol for an efficient, modifiedNegishi cross-coupling- strategy for substituted 2,2′-bipyridines employing tetrakis(triphenylphosphine)palladium(0) as a simple, commercially available, and relatively inexpensive catalyst for both 2-bromo- and 2-chloropyridines has been developed. Further transformations were carried out yielding some new valuable functionalized 2,2′-bipyridines.

The present invention relates to novel benzamides derivatives of formula (I)
as modulators of PPAR-gamma receptor, to processes for their preparation, to pharmaceutical compositions comprising said compounds and to said compound for use in the treatment of pathological conditions, disorders or diseases that can improve by modulation of PPAR-gamma receptor, such as cancer; metabolic diseases, inflammatory diseases, respiratory disorders, autoimmune diseases, neurodegenerative diseases, cardiovascular diseases and renal diseases.
Amino-functionalized 2,2′-bipyridines are versatile building blocks for the synthesis of sophisticated chelating ligands with the 2,2′-bipyridine core. The 4-, 5-, and 6-substituted 2-chloro- and 2-bromopyridine building blocks were prepared and coupled to symmetrically and non-symmetrically diamino-functionalized compounds by homo- and cross-coupling procedures. Further transformations were carried out to demonstrate the synthetic versatility of these compounds and the employed procedures.
