the tertiary amine attachments to the phenoxazine nucleus linked through a three- or four-carbon alkyl chain resulted in enhanced anti-MDR activity. On the basis of their 50% growth inhibitory (IC50) values, five of the ten compounds, namely, 10-(3'-chloropropyl)phenoxazine, 10-[3'-[N-bis(hydroxyethyl)- amino]propyl]phenoxazine, 10-(3'-N-morpholinopropyl)phenoxazine, 10-(4'-N-morpholinobutyl)phenoxazine
合成了一系列21种N-取代的吩恶嗪,以期在癌症化学治疗中找到更具特异性和毒性较小的多药耐药性(MDR)调节剂。因此,发现N-(ω-氯烷基)-和N-(氯酰基)苯恶嗪在与各种仲胺(包括N,N-二乙胺,N,N-二乙醇胺,吗啉,哌啶,吡咯烷和(β-羟乙基)哌嗪 产品通过UV,IR,1H-和13C-NMR,质谱数据和元素分析进行表征。检查了所有化合物的细胞毒性,以及它们在具有多重耐药性的GC3 / Cl(人结肠腺癌)和KBChR-8-5(HeLa)中增加长春花生物碱,长春新碱(VCR)和长春碱(VLB)积累的能力。变体)细胞系。将化合物与标准调节剂维拉帕米(VRP)进行比较。位置10的吩恶嗪环上的取代与抗增殖和抗MDR活性的增加有关。烷基桥的长度和氨基侧链类型的改变也影响了这些作用的效力。从检查的化合物中,发现10种衍生物相对于VRP的作用增加了GC3 / Cl和KBChR-8-5细胞中VCR和
