spacered dimericacridinecompounds was prepared. Their ability to interrupt the protein association of prion‐ and Alzheimer‐specific proteins and Ab peptides was explored using a fast screening system based on FACS analysis. The bis‐acridines displayed a higher activity than the corresponding monomers. Among these derivatives, best results were obtained with the 2,4‐dimethoxy‐6‐nitro compound 7h for

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.

Synthesis and biological evaluation of acridine-based histone deacetylase inhibitors as multitarget agents against Alzheimer’s disease
treating Alzheimer's disease (AD), which has a complex pathogenetic mechanism. In this study, the HDAC inhibitor core is incorporated into the acetylcholine esterase (ACE) inhibitor acridine–derived moiety. Some resulting compounds exhibited higher class IIa HDAC (4, 5, 7, and 9)- and class IIb HDAC6-inhibiting activity than did the reference SAHA as a pan-HDAC inhibitor in clinical practice. One of these
compounds consisting of an intercalating acridine‐derived part, a spacer region and a reactive EDTA‐derived conjugate was synthesized in an easy sequence. Thus, suitably mono‐protected 1, ω‐alkyldiamines gave, upon reaction with 9‐chloro‐2‐trifluoromethoxyacridine, followed by deprotection and reaction with EDTA dianhydride, the target molecules. Incorporation of their Fe(II) complexes in the presence of ascorbate
一系列抗病毒活性化合物由嵌入的吖啶衍生部分、间隔区和反应性 EDTA 衍生的偶联物组成,以简单的顺序合成。因此,合适的单保护 1, ω- 烷基二胺与 9-氯-2-三氟甲氧基吖啶反应,然后脱保护并与 EDTA 二酐反应,得到目标分子。在抗坏血酸存在下掺入它们的 Fe (II) 复合物使 MS2 噬菌体的噬菌体滴度降低了几个对数几十。
