主な解析化合物:Iejimalide A, BNS-22

  1. Proteomic profiling system for drug target analysis using 2D-DIGE.(2)
  2. Clustering of BNS-22 and well-known inhibitors based on the data of proteomic analysis using 2D-DIGE.

HeLa cells were treated with compound or with DMSO for 18 h were analyzed by 2D-DIGE and hierarchical cluster analysis was performed using the quantitative data of spots. The target of BNS-22 was estimated to Topo II by the system and inhibitory activity against Topo II was verified. This figure was modified based on the previously published data.(3)
