Facile Synthesis of Novel Indeno[1,2‐b]indol‐10‐one Derivatives by the Oxidation with DDQ
摘要:
The synthesis of indeno[1,2-b]indol-10-one analogues with a wide range of biological activities was described. They are also important intermediates of some selective estrogen receptor modulators (SERMs).

Provided are modified cycloalkyne compounds; and methods of use of such compounds in modifying biomolecules. Embodiments include a cycloaddition reaction that can be carried out under physiological conditions. The cycloaddition reaction involves reacting a modified cycloalkyne with an azide moiety on a target biomolecule, generating a covalently modified biomolecule. The selectivity of the reaction and its compatibility with aqueous environments provide for its application in vivo and in vitro.

efficient method was developed for the construction of the medicinally important tetracyclic 3-spirooxindole benzofuranones. In this highly atom- and step-economical one-pot protocol, one quaternary carbon center, two new cycles, and four new bonds (C–C/C–O/C–N) were formed under simple ligand-free copper-catalyzed conditions through a novel tandem oxidative annulation strategy.

enzymes. KI values of these compounds against hCA I and hCA II were in the range of 2.14–16.32 μM, and 0.34–2.52 μM, respectively. Isozyme hCA IV was inhibited with KI-s in the range of 0.435–5.726 μM, while hCA VI with KI-s of 1.92–12.84 μM bCA III was inhibited with KI-s in the range of 2.13–17.83 μM. The structurally related compounds, 1,2-dimethoxybenzene, catechol and indole were also tested in order
制备了几种在分子的茚基片段上掺入甲氧基,羟基和卤素(F,Cl和Br)部分的5,10-二氢茚并[1,2- b ]吲哚衍生物,并针对五种碳酸酐酶(CA,EC 4.2.1.1)同工型。评估了这些化合物对人(h)同工型hCA I,II,IV,VI和牛(b)同工型bCA III的抑制能力。它们中的大多数对这些酶表现出低的微摩尔抑制作用。这些化合物针对hCA I和hCA II的K I值分别在2.14–16.32μM和0.34–2.52μM范围内。同工酶HCA IV用抑制ķ我-s在0.435-5.726μM的范围内,而HCA VI与ķ我-s为1.92–12.84μM,K I -s抑制bCA III的范围为2.13–17.83μM。为了理解结构活性关系,还测试了与结构相关的化合物1,2-二甲氧基苯,邻苯二酚和吲哚。在计算机对接研究中,还对hCA I和II活性位点内的某些衍生物进行了研究,以理顺这些化合物的抑制特性并了解其抑制机理。
Antioxidant activity of 5,10-dihydroindeno[1,2-b]indoles containing substituents on dihydroindeno part
10-dihydroindeno[1,2-b]indoles (3a–t) containingsubstituents such as methoxy, hydroxyl, and halogen (F, Cl, and Br) on indeno part was described. Antioxidant and radical scavenging activities of synthesized compounds (3a–t) were determined by various in vitro assays such as 1,1-diphenyl-2-picryl-hydrazyl freeradicals (DPPH), 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid radicals (ABTS+), N,N-dimethyl-p-phenylenediamine
