摘要:
磁性可分离的无机-有机杂化材料H 5 PW 10 V 2 O 40 /吡啶-Fe 3 O 4(HPA / TPI-Fe 3 O 4)纳米颗粒为通过以下方法合成取代的双(吲哚基)甲烷提供了一种有效而经济的途径在无溶剂条件下用各种醛和酮对吲哚进行亲电取代,在不到30分钟的时间内即可获得优异的收率。通过将H 5 PW 10 V 2 O 40化学固定在Fe 3 O 4上来制备该催化剂。通过使用N- [3-(三乙氧基甲硅烷基)丙基]异烟酰胺(TPI)接头制备纳米颗粒。高催化活性和使用外部磁场易于回收是该新型催化系统的其他环保特性。催化剂被循环至少八次而没有明显的催化活性损失。用于HPA / TPI-Fe 3 O 4的表征技术(如XRD,SEM和FTIR)证明,保留了吡啶改性的Fe 3 O 4纳米颗粒表面上的钨-钒磷酸的Keggin结构。

Disclosed herein are compounds capable of inducing apoptosis through promoting Nur77 interaction with Bcl-2 and through modulating mitochondrial activities. Also disclosed herein are compositions and methods using these compounds and compositions. Nur77 is a key regulator of Bcl-2 activities and is capable of converting Bcl-2 from an anti-apoptotic protein to a pro-apoptotic protein. Small molecules that directly modulate the Nur77/Bcl-2 apoptotic pathways are promising for treating diseases with abnormal levels of Bcl-2, Nur77, or combinations thereof, including cancers.

improved protocol for the synthesis of bis(indolyl)methanes using 6 mol% [BCMIM][Cl] ionicliquid via facile, one-pot, metal-free synthesis in aqueous ethanol at ambient temperature. In 15–55 min, a series of 48 derivatives were obtained in up to 94 % yields and were characterized using several spectroscopic techniques. UV–visible and fluorescence spectroscopies were used to investigate the photophysical behaviour
Friedel–Crafts Alkylation of Indoles with Aldehydes/Ketones Catalyzed by Bromodiarylethene-Based Photoacid Generators

Diarylethenes (DAEs) with a bromine atom at the ring-closing position catalyze C–C bonding reactions induced by UV or sunlight. Upon photo-irradiation, bromodiarylethenes undergo 6π-electrocyclization (6π-EC), followed by the release of an acid species that catalyzes the double Friedel–Crafts addition of indoles to aldehydes and isatins to form the corresponding triarylmethanes and 3,3′-diarylindolin-2-ones
