Tumour inhibitors from plants. Anti-cancerous plants in nature

      Аннотация: Though the antitumour screening programmes have resulted in the identification of a number of cytoxic and antitumour agents only small number of clinical agents are produced. The major success area for antitumour drugs in general, is against rapidly proliferating tumours and there are now effective treatments for cancers such as childhood leukemia’s, testicular tumours and non Hodgkin’s lymphoma which where very fatal formerly. However, adult solid tumour such as lung, breast and colon tumours still respond poorly to chemotherapy. There are large differences among the tumour types leading significant differences in their sensitivity to drugs it is quite impossible or unlikely that a broad spectrum anticancer drug will actually be founded. The assay methods used in the screening programmes had to be rapid to cope with the large number of samples tested and consequently rapidly –dividing tumour lines are employed for biological testing. So naturally the antitumour agents deleted are those effective against fast growing tumours and they have little activity in slow growing tumours in human studies.
