Poloxamer/sodium cholate co-formulation for micellar encapsulation of Doxorubicin with high efficiency for intracellular delivery: an in-vitro bioava…
2020
Abstract Hypothesis Doxorubicin hydrochloride (DX) is widely used as a chemotherapeutic agent, though its severe side-effects limit its clinical use. A way to overcome these limitations is to increase DX latency through encapsulation in suitable carriers. However, DX has a high solubility in water, hindering encapsulation. The formulation of DX with sodium cholate (NaC) will reduce aqueous solubility through charge neutralization and hydrophobic interactions thus facilitating DX encapsulation into poloxamer (F127) micelles, increasing drug latency. Experiments DX/NaC/PEO-PPO-PEO triblock copolymer (F127) formulations with high DX content (DX-PMs) have been prepared and characterized by scat…
Studies on the Intravesical Action of Topically Administered G 3 H-Doxorubicin Hydrochloride in Men: Plasma Uptake and Tumor Penetration
1980
AbstractDoxorubicin hydrochloride has been used for the treatment and prevention of recurrences of transitional cell carcinoma. Ideal indications for the drug and side effects have not been determined. In this regard the penetration of the drug into the bladder wall and the urothelium as a urinary blood barrier is of interest. Using a tritium label we have investigated tumor penetration and transmucosal plasma uptake of doxorubicin hydrochloride after intravesical application in 7 patients with stage A bladder tumors. Of the 7 patients 5 were free of tumor following transurethral resection and 2 had recurrent disease. The patients free of tumor received 40mg. doxorubicin hydrochloride per 3…
Folic acid-functionalized graphene oxide nanosheets via plasma etching as a platform to combine NIR anticancer phototherapy and targeted drug deliver…
2020
PEGylated graphene oxide (GO) has shown potential as NIR converting agent to produce local heat useful in breast cancer therapy, since its suitable photothermal conversion, high stability in physiological fluids, biocompatibility and huge specific surface. GO is an appealing nanomaterial for potential clinical applications combining drug delivery and photothermal therapy in a single nano-device capable of specifically targeting breast cancer cells. However, native GO sheets have large dimensions (0.5-5 mu m) such that tumor accumulation after a systemic administration is usually precluded. Herein, we report a step-by-step synthesis of folic acid-functionalized PEGylated GO, henceforth named…
