Nanoparticle encapsulation has been used as a means to manipulate the pharmacokinetic (PK) and safety profile of drugs in oncology. Using pegylated liposomal doxorubicin (PLD) vs. conventional doxorubicin as a model system, we developed and experimentally validated a multiscale computational model of liposomal drug delivery. We demonstrated that, for varying tumor transport properties, there is...
Here, we report a method to specifically bind liposomal radiopharmaceuticals to a CoCrMo alloy, which can be used in arterial stents, via an irreversible inverse electron-demand Diels-Alder reaction. Inspired by recent accomplishments in pre-targeted imaging using tetrazine-trans-cyclooctene click chemistry, we synthesized 89Zr-labeled trans-cyclooctene-functionalized liposomal nanoparticles, w...
Liposomal glutathione, but not the control liposomes (with no glutathione), dose-dependently inhibited copper ion-induced low density lipoprotein (LDL) and HDL oxidation. As peroxidase activity was found to be present in both LDL and HDL, it has contributed to the anti-oxidative effects of liposomal glutathione. In-vitro, no significant effect of liposomal glutathione on J774 A.1 macrophage cel...
OBJECT Targeted drug delivery with immunoliposomes has been applied to various in vivo animal models and is newly focused as a novel therapeutic target. Lectin-like oxidized low-density lipoprotein receptor-1 (LOX1) is a potent regulator of systemic atherosclerosis, and the authors focused on its effect on carotid plaques. The authors developed a LOX1-targeted liposomal rho-kinase inhibitor and...
We have determined the pharmacokinetics of liposomal vincristine, in a Lewis lung carcinoma solid tumor model in mice, with the aim of differentiating the contribution of liposomal and nonliposomal (released from liposomes) drug pools to the overall pharmacokinetic profile. Two types of liposomal formulations were used: one composed of 1,2 distearoyl-sn-glycero-3-phosphocholine/cholesterol (Cho...
BACKGROUND The prognosis of acute lymphoblastic leukemia in the elderly is poor. The GRAALL-SA1 phase II, randomized trial compared the efficacy and toxicity of pegylated liposomal doxorubicin versus continuous-infusion doxorubicin in patients 55 years or older with Philadelphia chromosome-negative acute lymphoblastic leukemia. DESIGN AND METHODS Sixty patients received either continuous-infu...
vitamin e (α-tocopherol) is a natural antioxidant very useful for preventing the harmful effects of uv sun rays as skin aging and cancers. in this study, different mlv formulations were made using egg lecithin and varying molar ratios of α-tocopherol and/or cholesterol, and their encapsulation efficiencies were determined. the best liposomal product was incorporated into a carbomer 980 gel. the...
Pseudohyperphosphatemia due to an interaction between liposomal amphotericin B and the Beckman Coulter PHOSm assay occurs sporadically and remains underrecognized in clinical practice. This retrospective case-control study compares the incidences of hyperphosphatemia in adult inpatients exposed to liposomal amphotericin B or a triazole. A case series of patients with confirmed pseudohyperphosph...
Brain cancer is a devastating disease affecting many people worldwide. Effective treatment with chemotherapeutics is limited due to the presence of the blood-brain barrier (BBB) that tightly regulates the diffusion of endogenous molecules but also xenobiotics. Glutathione pegylated liposomal doxorubicin (2B3-101) is being developed as a new treatment option for patients with brain cancer. It is...
BACKGROUND The inflammatory tumor microenvironment, and more specifically the tumor-associated macrophages, plays an essential role in the development and progression of prostate cancer towards metastatic bone disease. Tumors are often characterized by a leaky vasculature, which - combined with the prolonged circulation kinetics of liposomes - leads to efficient tumor localization of these drug...
