Use | Antineoplastic drugs. The product for the cell cycle non-specific drugs, mainly for the G1 phase and M phase. The low dose of the product inhibited the production of bone marrow granulocytes and had little effect on red blood cells and lymphocytes. High dose had little effect on red blood cells and lymphocytes. In large doses, the production of red blood cells and lymphocytes was inhibited. Due to the selective effect, the effect of chronic myeloid leukemia is significant. Busulfan is the main drug for the treatment of chronic myeloid leukemia, and its remission rate can reach 80-90%. But should be discontinued in the event of acute lesions. |
In vitro study | Busulfan inhibits the frequency of cell formation in the cobblestone region, but does not cause a significant increase in apoptosis of hematopoietic stem cell-like cells and progenitor cells. Busulfan inhibits the hematopoietic function of HSC-like cells and progenitor cells through an apoptosis-dependent mechanism. Busulfan induces bone marrow hematopoietic cell senescence in a time-dependent manner, which is similar to p16 in normal human diploid fibroblast WI38, Busulfan (alkylating agent) causes DNA damage by cross-linking DNA and protein, senescence is independently induced by extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein kinase (p38 protein) cascades. Busulfan induced a transient decrease in glutathione but not a sustained increase in ROS production. In testicular cells, Busulfan prevents apoptosis of spermatogonial stem cells by inhibiting the expression of PCNA and inducing Rb hypophosphorylation. |
In vivo study | The Busulfan-treated mice showed a marked increase in apoptosis and a decrease in testicular weight. Busulfan(40 mg/kg) induced apoptosis in the maximum number of cells while reducing the number of necrotic cells. In NOD/SCID mice, Busulfan treatment and irradiation resulted in similar detection sensitivity of HSC by limiting dilution analysis. The Busulfan transplanted mice had slow and incomplete lymphatic engraftment. Busulfan(20 mg/kg to 100 mg/kg) dose-dependently provided homotypic lymphoid recombination in mice. |
