regarding the ati cancer drugs. - jesh - ArchivalUser - 12-20-2007 can any one please give me the list of drugs which are cell cycle specific 0 - ArchivalUser - 12-20-2007 I don't have the complete list: but some include vincristine, 5-Floro uracil, etopoxide, taxels (doxitaxel), hydroxyurea..... 0 - ArchivalUser - 12-20-2007 thanks, but i would like to knew,that all these drugs are acting in which phases of cell cycle. 0 - ArchivalUser - 12-20-2007 Jesh, here are the specific phases in w/c they act: Antimetabolites (e.g. 5 Flourouracil)...............................S Alkaloids (e.g. Doxorubucin, ActinomycinD)....................S and M Vincristine...................................................................M Topo inhibitors (e.g. Etopoxide).....................................S Taxanes (e.g. Docetaxel)..............................................M Hydroxyurea ..............................................................?S (not well known) Az 0 - ArchivalUser - 12-20-2007 thanks for ur response. 0 - ArchivalUser - 12-20-2007 bleomycin acts in G2 phase 0 - ArchivalUser - 12-20-2007 etoposide acts on both G2 and S phase. correct me if i am wrong. 0 - ArchivalUser - 12-20-2007 Ya, makes sense. In G2,cells are transcriptionaly active and need the Topo II to deal with changing topology during the process. But I think cells need it more during S phase, that may be why thy put it under S-specific. |
