Catalog No. T0923 Copy Product Info
Purity: 99.89%
Busulfan is an alkylating antineoplastic agent derived from dimethane sulfonate, with cytotoxic and immunosuppressive properties. It primarily acts by forming carbonium ions in vivo, which induce cross-linking between DNA strands or between DNA and proteins, leading to DNA damage, inhibition of DNA replication, and suppression of RNA transcription. In addition, Busulfan can inhibit thioredoxin reductase and induce apoptosis. It is commonly used as a myeloablative agent in preconditioning regimens for bone marrow transplantation and can also be used to establish anemia models.

Product Introduction

Bioactivity
Description
Busulfan is an alkylating antineoplastic agent derived from dimethane sulfonate, with cytotoxic and immunosuppressive properties. It primarily acts by forming carbonium ions in vivo, which induce cross-linking between DNA strands or between DNA and proteins, leading to DNA damage, inhibition of DNA replication, and suppression of RNA transcription. In addition, Busulfan can inhibit thioredoxin reductase and induce apoptosis. It is commonly used as a myeloablative agent in preconditioning regimens for bone marrow transplantation and can also be used to establish anemia models.
In vitro
Mice transplanted with busulfan exhibit slow and incomplete lymphoid engraftment. Mice treated with busulfan demonstrate a significant increase in apoptosis and a reduction in testicular weight. In NOD/SCID mice, busulfan treatment combined with irradiation achieves a detection sensitivity similar to that of limiting dilution assays. A dose-dependent lymphoid tissue reconstitution is provided in mice with 20 mg/kg to 100 mg/kg of busulfan. At 40 mg/kg, busulfan induces the maximum number of apoptotic cells while minimizing the number of necrotic cells.
In vivo
Busulfan, an alkylating agent that induces DNA damage through cross-linking DNA with DNA and proteins, triggers senescence in normal human diploid WI38 fibroblast cells via a cascade mediated by extracellular signal-regulated kinase (Erk) and p38 mitogen-activated protein kinase (p38 MAPK), independent of the p53-DNA damage pathway. Busulfan causes a transient reduction in glutathione levels, followed by a sustained increase in ROS production. The hypophosphorylation of Rb induced by Busulfan inhibits the expression of PCNA in testicular cells, preventing apoptosis of spermatogonial stem cells. Moreover, while Busulfan reduces the frequency of cobblestone area-forming cells, it does not significantly increase apoptosis in hematopoietic stem cells (HSC)-like cells and progenitor cells with similar phenotypes. Busulfan suppresses the hematopoietic function of HSC-like cells and progenitor cells through an apoptosis-dependent mechanism. Additionally, Busulfan-induced senescence in bone marrow hematopoietic cells correlates with a time-dependent increase in the expression of p16Ink4a and p19Arf.
Disease Modeling Protocol
Aplastic Anemia (AA) Model
  • Modeling Mechanism:

    Busulfan combined with cyclophosphamide induces apoptosis (AA) through a dual damage mechanism: on the one hand, it directly destroys bone marrow hematopoietic stem cells/progenitor cells, inhibiting hematopoietic function; on the other hand, it activates inflammatory pathways, inducing high expression of RIP1 and RIP3 proteins in bone marrow cells and forming the RIP1-RIP3 necrosis complex, mediating necrotizing apoptosis of hematopoietic cells, while promoting the release of inflammatory factors such as IL-6, TNF-α, and FLT-3L, further aggravating the damage to the bone marrow hematopoietic microenvironment, ultimately leading to pancytopenia in peripheral blood and fatty degeneration of bone marrow hematopoietic tissue.

  • Modeling Method:

    Experimental Subject:

    Mice: ICR strain, male, 18–22 g, 6–8 weeks old

    Dosage and Administration Route:

    Intervention group: Nec-1 (necrotic apoptosis inhibitor) group received intraperitoneal injection of Nec-1 (2 mg/kg/day) prior to combined administration, followed by combined administration of Busulfan (20 mg/kg/day)+Cyclophosphamide (40 mg/kg/day) via intraperitoneal injection
    Control group: Intraperitoneal injection of an equivalent volume of physiological saline

    Dosing Frequency and Duration Model:

    Once daily for 12 consecutive days

  • Validation:

    Hematological markers: Peripheral blood leukocytes (WBC), erythrocytes (RBC), hemoglobin (Hb), and platelets (PLT) were significantly decreased; bone marrow nucleated cell (BMNC) count decreased by 68.25%. Histological markers: Bone marrow hematopoietic tissue was replaced by adipose tissue, the hematopoietic area was reduced, the number of megakaryocytes and hematopoietic cells decreased, and the number of non-hematopoietic cells (adipocytes, endothelial cells) increased, accompanied by tissue edema, congestion, and focal necrosis. Cell death detection: Flow cytometry showed a significantly increased early apoptosis rate and mid-to-late apoptosis/necrosis rate of bone marrow cells. Fluorescent staining (Hoechst/PI) and scanning electron microscopy revealed apoptotic cells (cell membrane invagination) and necrotic cells (cell membrane blistering and swelling). Molecular markers: Western blot detected upregulated expression of RIP1 and RIP3 proteins in bone marrow cells (RIP3 began to increase from day 3 of drug administration, and RIP1 began to increase from day 9). Immunoprecipitation confirmed RIP1-RIP3. Complex formation; levels of IL-6, TNF-α, and FLT-3L were significantly elevated in bone marrow tissue supernatant (FLT-3L increased 4.46-fold).

*Precautions: Mice were euthanized by cervical dislocation, and one femur was surgically removed. After obtaining the femoral epiphysis, bone marrow cells were washed away with 1 ml of PBS to prepare a bone marrow cell suspension.
