To enable studies to elucidate the intracellular processing and targeting of the potent cytostatic/apoptotic anticancer natural products phorboxazoles A and B, a fluorescent derivative has been developed. This involved the total syntheses of the terminal alkyne 33-O-Me-45,46-dehydrobromophorboxazole A (MDHBPA) and a terminal vinyl iodide derivative of the blue fluorescent dye N,N,-dimethyl-7-aminocoumarin
为了使研究阐明强力的细胞生长抑制/凋亡抗癌天然产物佛波唑A和B的细胞内加工和靶向,已开发了荧光衍生物。这涉及末端炔33-O-Me-45,46-脱氢溴代发霉唑A(MDHBPA)和蓝色荧光染料N,N,-二甲基-7-氨基香豆素(DMC)的末端乙烯基碘衍生物的全部合成。这些合作伙伴的Sonogashira偶联提供了高产的烯炔DMC-MDHBPA。
