PURPOSE The objectives of this study were to synthesize and characterize two types of cytarabine (Ara-C) lipid produgs and evaluate the prodrugs for sustained intraocular delivery after administration by intravitreal injection. METHODS Hexadecyloxypropyl cytarabine 5'-monophosphate (HDP-P-Ara-C) and hexadecyloxypropyl cytarabine 3',5'-cyclic monophosphate (HDP-cP-Ara-C) were synthesized start...
The standard therapy for acute myelogenous leukemia (AML) continues to be based on cytarabine (ara-C, DepoCyt, Enzon), typically in combination with anthracyclines such as idarubicin (Idamycin, Pfizer) or daunorubicin (Cerubidine, Bedford). Although 60% to 70% of patients achieve complete remissions (CRs), most patients relapse and ultimately die of the disease or of associated complications. T...
Autologous hematopoietic stem cell transplantation is recommended and significantly improved the prognosis of lymphoma patients. However, preferred conditioning regimen prior to autologous still a controversial topic. Current experiment was aim explore efficacy safety BEAC (carmustine, etoposide, cytarabine cyclophosphamide), BEAM melphalan) Be-EAM (bendamustine, cytarabine, etoposide preparati...
In chronic myelogenous leukemia (CML) imatinib mesylate has been shown to selectively inhibit the tyrosine kinase domain of the oncogenic bcr-abl fusion protein. Using this agent alone high rates of cytogenetic responses were recorded. However, several mechanisms of resistance have been described. In vitro studies examining the effects of imatinib mesylate plus cytarabine have shown synergistic...
Leukemia stem cells (LSCs) are regarded as the origin of leukemia and its recurrence. Side population (SP) cells possess some intrinsic stem cell properties and contain numerous LSCs. In this study, we examined the prognostic significance of cluster differentiation 47 (CD47) and identified the appropriate target for eliminating LSCs. We determined the percentage of SP cells in a THP-1 cell popu...
To overcome unsatisfactory results of classical low-dose cytarabine (LDAC) of cytarabine ≤20 mg twice daily (BID) subcutaneously for 10 days for patients with elderly acute myeloid leukemia (eAML), we evaluated a modified LDAC (mLDAC) of cytarabine 20 mg/m2 BID subcutaneously plus etoposide 50 mg BID orally for 14 days. To determine its feasibility, we compared outcomes of 77 and 42 eAML patien...
Cytarabine, an analog of deoxycytidine, is an important agent in the treatment of ovarian carcinoma, acute myeloid and lymphoblastic leukemia. Its mechanism of action has been attributed to an interference with DNA replication. The plasma membrane has received increasing attention as a possible target of antitumor drugs, where the drugs may act as growth factor antagonists and receptor blockers...
Mnk kinases regulate the phosphorylation and activation of the eukaryotic initiation factor 4E (eIF4E), a protein that plays key roles in the initiation of messenger RNA translation and whose activity is critical for various cellular functions. eIF4E is deregulated in acute myeloid leukemia (AML), and its aberrant activity contributes to leukemogenesis. We determined whether cercosporamide, an ...
BACKGROUND Cytarabine use during pregnancy carries a 5-7% risk of neonatal cytopenia. We report two cases of fetal myelosuppression following high-dose cytarabine administration for acute myeloid leukemia (AML). CASE 1 A 36-year-old G9P6 diagnosed with AML at 21 weeks was monitored for fetal anemia weekly and growth monthly. At 33 weeks (after 2 cycles), BPP was 2/10 and MCA PSV was elevated ...
