been shown higher in vitro potency than imiquimod. Besides, triazole, oxadiazole, and thiadiazole rings are privileged building blocks in drug design. A series of [1,2,4]triazolo[4,3-a]quinoxaline-1,3,4-oxadiazole and [1,2,4]triazolo[4,3-a]quinoxaline-1,3,4-thiadiazole derivatives were therefore synthesized by incorporation of these rings into the structure of EAPB0203 and assessed their antiproliferative
咪喹莫特(1-异丁基-1 H-咪唑并[4,5 - c ]喹啉-4-胺)对某些类型的皮肤癌有效。结构相似的EAPB0203(N-甲基-1-(2-苯乙基)咪唑并[1,2 - a ]喹喔啉-4-胺)的体外药效比咪喹莫特更高。此外,三唑,恶二唑和噻二唑环是药物设计中的重要组成部分。一系列[1,2,4]三唑并[4,3 - a ]喹喔啉-1,3,4-恶二唑和[1,2,4]三唑并[4,3- a因此,通过将这些环并入EAPB0203的结构中来合成]喹喔啉-1,3,4-噻二唑衍生物,并评估它们对多种癌细胞系的抗增殖作用。与咪喹莫特和EAPB0203相比,1,3,4-恶二唑衍生物表现出卓越的功效。我们的发现突出了[1,2,4]三唑并[4,3 - a ]喹喔啉-1,3,4-恶二唑衍生物作为抗癌剂的巨大潜力。
