Novel polyaza heterocycles, dipyrido[3,2-a:2',3'-c]quinolino[2,3-h]phenazines, were synthesized via a regiocontrolled condensation between 5,6-phendione and 3,4-diaminoacridine derivatives. (C) 2002 Elsevier Science Ltd. All rights reserved.
Functionalization of the A ring of pyridoacridine as a route toward greater structural diversity. Synthesis of an octacyclic analogue of eilatin
In an effort to increase the structural diversity of pyrido[4,3,2-kl] acridines, compounds containing amino substituents on the A ring were synthesized. The key-reactions involve regioselective electrophilic aromatic substitutions. The methodology was applied to the synthesis of the extended angular octacycle 8, which conjugates the physicochemical and spectroscopic properties of the pyridoacridine skeleton with the ability of [1,10] phenanthroline ring for metal complexation. The 9-aminopyridoacridine 4 displays significant cytostatic activities against two cancer cell lines, and may be considered as a new lead in the search of active derivatives. (C) 2009 Elsevier Ltd.

conformations, we report an efficient synthesis of new Troger's Base analogs derived from polyfunctionalized aminoacridines treated with a stoechiometric amount of formaldehyde in trifluoroacetic acid. For the more sensitive aminoacridines, the Troger'sBases were obtained by nucleophilic substitution of the chloro group of the “pre-formed” corresponding Troger's Base.
摘要 在寻找 DNA 构象的化学探针的过程中,我们报告了一种新的 Troger's Base 类似物的有效合成,该类似物来源于用三氟乙酸中化学计量的甲醛处理的多官能化氨基吖啶。对于更敏感的氨基吖啶,Troger 碱是通过“预先形成的”相应 Troger 碱的氯基团的亲核取代获得的。
