Biomimetic semi-synthesis of fradcarbazole A and its analogues
摘要:
The first synthesis of fradcarbazole A (1) has been accomplished by using a biomimetic intramolecular cyclization/dehydration to construct the staurosporine-thiazole-indole skeleton. The phenyl and oxazole analogues of fradcarbazole A (2-4) were also synthesized using the same strategy. Compounds 1-4 displayed cytotoxicity against A549 cell line with IC50 values of 0.4-3.6 mu M, induction of G(0)/G(1) arrest of A549 cell cycle at 10 mu M, and inhibition of PK-beta kinase with IC50 values of 0.5-0.9 mu W.
