The structures elucidated by analysis 1D/2D NMR, high-resolution electrospray ionization mass...
Radiotherapy using ionizing radiation is a major therapeutic modality for advanced human lung cancers. However, itself can induce malignant behaviors such as cancer cell migration and invasion, leading to local recurrence or distal metastasis. Therefore, safer more effective agents that inhibit the metastatic of cells in radiotherapy are needed.
