N-(氨基亚氨基甲基)-1H-吲哚羧酰胺衍生物作为Na + / H +交换抑制剂的合成及其生物活性。
摘要:
合成了一系列的N-(氨基亚氨基甲基)-1H-吲哚羧酰胺衍生物,并测定了它们对Na + / H +交换剂的抑制能力。吲哚环系统2到7位羰基胍基团的变化表明,在2位取代可以最有效地提高Na + / H +交换子的抑制活性。这导致合成和评估了一系列广泛的N-(氨基亚氨基甲基)-1H-吲哚-2-羧酰胺衍生物。在吲哚环系统的1-位具有烷基或取代的烷基的衍生物显示出更高水平的体外活性。N-(氨基亚氨基甲基)-1-(2-苯乙基)-1H-吲哚-2-羧酰胺(49)具有最强的活性。

wide range of substitutedindoles, including complex polycyclic‐architectures were easily assembled by means of a Amberlyst 15H catalyzed synthesis that employs 1,2‐diaza‐1,3‐dienes and anilines. The metal and oxidant free methodology proposed here is characterized by good yields, total and predictable regioselectivity, and the ability to provide electron withdrawing substitutedindoles.

The synthesis and alpha 2-adrenergic activity of a series of indolin-2-yl and tetrahydroquinolin-2-yl imidazolines are described. The indolin-2-yl imidazoline 4b was found to possess potent alpha 2-adrenergic agonist and antagonist activity. The modification of the substituents on the indoline ring of 4b has led to the separation of these activities. Substitution on the aromatic ring of 4b with halogen or increasing the size of the N-alkyl substituent of 4b gave alpha 2-adrenergic antagonists without agonist activity. The N-allylindoline 4d is more potent than idazoxan in vitro and is equipotent in vivo, but is less receptor selective (alpha 2 vs. alpha 1) than idazoxan. The cis-1,3-dimethylindolin-2-yl imidazoline 6a is an alpha 2-adrenergic agonist equal in potency to clonidine in vitro, while the trans-1,3-dimethylindolin-2-yl imidazoline 6b is a moderately potent alpha 2-adrenergic antagonist.
