K 区芳烃氧化物在乙腈中通过两个酸催化步骤重排为苯酚:将芳烃氧化物快速重排为 K 区苯酚的位置异构酮互变异构体,然后缓慢烯醇化。酮的积累是水溶液中芳烃氧化物的酸催化溶剂分解中提出的中间体,首次允许在溶剂分解条件下直接进行光谱观察和表征。报告了苯并 [a] 蒽的 K 区芳烃氧化物、其 1-、4-、7-、11-、12-甲基和 7,12-二甲基取代衍生物苯并 [a] 的速率常数和产物芘、苯并[c]菲、3-溴菲、屈、二苯并[a,h]蒽、菲和芘
The present invention relates to a system of multi-stage stem cell carcinogenesis and a method of generating such multi-stage stem cell carcinogenesis system. Various stages of cancer stem cells can be generated from normal stem cells via mutagenesis. The system of the present invention enables monitoring changes in the ability of cells to transition from one stage of carcinogenesis to another and to identify genetic pathways and molecules that influence carcinogenesis. The present invention also enables a high-throughput and nonbiased screening for targets that preferentially affect cancer stem cells relative to non-cancer stem cells or their derivatives during stem cell carcinogenesis, thus is useful in developing anti-cancer therapeutics.
