Associations of C08545 with other chemical compounds

  • A novel acetogenin, joolanin ( 1), along with eight known acetogenins, squamocin ( 2), desacetyluvaricin ( 3), chamuvarinin ( 4), tripoxyrollin ( 5), diepoxyrollin ( 6), dieporeticanin-1 ( 7), dieporeticanin-2 ( 8) and dieporeticenin ( 9) were isolated from the seeds of UVARIA CHAMAE (Annonaceae) [8].
  • Bioactivity-directed fractionation of the MeOH extract of the stem barks of Rollinia emarginata resulted in the isolation of six compounds, four acetogenins, rolliniastatin-1, sylvaticin, squamocin, and rollidecin B, one lignan, lirioresinol B, and an oxoaporphine, liriodenin [9].
  • Cytotoxic activity of adriamycin was not restored in MCF7-R Pgp expressing cells by squamocin addition [2].
 

Gene context of C08545

  • These results suggest that squamocin inhibits the proliferation of K562 cells via G2/M arrest in association with the induction of p21, p27 and the reduction of Cdk1 and Cdc25C kinase activities [3].
  • Selective cytotoxicity of squamocin on T24 bladder cancer cells at the S-phase via a Bax-, Bad-, and caspase-3-related pathways [10].
  • These results suggest that apoptosis of HL-60 cells induced by squamocin requires caspase-3 activation and is related to SAPK activation [5].
