Background technique
Cancer is the general designation of a major class malignant tumour, its main feature is that without limitation, without end hyperplasia.Cancer cell makes patient's body
Interior nutriment is largely consumed, while releasing a variety of toxin, and human body is made to generate a series of symptoms, cause human body it is thin,
Inability, anaemia, loss of appetite, fever and serious organ function are impaired, cause necrotic hemorrhage concurrent infection, patient finally by
It is dead in organ failure.
Signal transduction and (the Signal Transducer and Activator of of activating transcription factor -3
Transcription-3, STAT3) be a kind of GAP-associated protein GAP that can be activated by different cytokine receptors, cell because
Carrier is served as during son-acceptor interaction, the inherence specificity for keeping signal to transmit in the cell, and pass through induction target
The effect effect of biostimulation is expressed in genetic transcription, other than participating in angiogenesis and immune response, also with the increasing of cell
It grows, survive, breaking up, the close associations such as anti-apoptotic.STAT3 is in kinds of tumor cells (including blood such as leukaemia, Huppert's disease
A variety of entity tumors such as liquid tumour and lung cancer, breast cancer, prostate cancer) in abnormal expression increase, generation with malignant tumour,
Develop closely related.
By inhibiting STAT3 activity to be expected to that cancer cell is made apoptosis occur to achieve the purpose that treating cancer, study recently
It was found that inhibiting STAT3 signal that can overcome the chemical drug resistance including kinds of tumors such as retinoblastoma, lung cancer, leukaemia
Property, successfully research and development are a new antitumor target to STAT3.Therefore, new STAT3 inhibitor is actively found for cancer
Treatment have particularly important meaning.
