Convenient access to substituted acridines by a Buchwald–Hartwig amination
摘要:
A convenient, high yield procedure for the synthesis of anthranilic acids carrying a variety of different substituents as well as their straightforward transformation into the corresponding 9-chloroacridines could be established by using modified Buchwald-Hartwig amination conditions.

was investigated in-silico as a new molecular therapeutic target for these compounds. All compounds showed potential interactions with the catalytic residues. These results showed that acridine-9(10H)-one derivatives, in particular compounds II, VII, VIII and IX hold promise in the development of therapeutic agents against these free-living amoebae.
致病性A. castellanii和N. fowleri是机会主义的自由生活变形虫。棘阿米巴属 是肉芽肿性阿米巴脑炎 (GAE) 和阿米巴角膜炎 (AK) 的病原体,而福氏耐格里虫 ( Naegleria fowleri )引起非常罕见但严重的脑部感染,称为原发性阿米巴脑膜脑炎 (PAM)。吖啶酮是一种重要的杂环支架,合成和天然衍生物都显示出各种有价值的生物学特性。在本研究中,合成了 10 种合成吖啶酮衍生物 ( IX ),并针对两种变形虫进行了体外抗变形虫和杀囊肿活性的评估. 此外,还在体外进行了脱囊作用、包囊作用、细胞毒性、宿主细胞致病性。此外,对这些化合物与N. fowleri的三种组织蛋白酶 B 旁系同源酶进行了分子对接研究,以预测与病原体的可能对接模式。化合物VII对A. castellanii显示出有效的抗阿米巴活性,IC 50 为53.46 µg/mL,而化合物IX在体外对 N
Exploring tricycle acridines as prospective urease inhibitors: synthesis via microwave assistance, in vitro evaluation, kinetic profiling, and molecular docking investigations
deals with the microwave-assisted green synthesis of two acridine-based libraries and in vitroureaseinhibitoryactivities. The first library is based on 9-phenyl acridine 1–13 derivatives, while the second is based on 10H-acridin-9-one 14–33 derivatives. All compounds were characterized using FTIR, EI-MS, 1H-NMR, and CHNX techniques. As a result of in vitro evaluation of the synthesized derivatives
Anthranilic acid derivatives are used to inhibit the formation of advanced glycation end products to reduce complications in diabetes.

A practical nickel-catalyzed protocol for the synthesis of sterically hindered 9-arylacridines via Negishi type cross-coupling was developed. The method enables a convenient approach to a set of active acridine photocatalysts starting from commercially available 9-chloroacridine, inexpensive catalyst [NiCl2(Ph3P)2], and organozinc reagent with no need for additional ligands and precious metals. The
