Periplocymarin (PPM), a cardiac glycoside, has a narrow therapeutic index, poor tumor selectivity and severe cardiovascular toxicity which hinder its wide clinical applications in cancer treatment. Herein, we report novel redox-responsive prodrug-nanoparticles (MPSSV-NPs) self-assembled by
Cardiac glycosides could increase intracellular Ca2+ ion by inhibiting the Na+/K+ATPase to induce apoptosis in many tumor cells. However, narrow therapeutic index, poor tumor selectivity and severe cardiovascular toxicity hinder their applications in cancer treatment. To improve the safety profile
Cardiac glycosides (CGs) have been used to treat cancer for hundreds of years. However, the narrow therapeutic window and system toxicity have hindered their wide clinical applications. Herein, the small molecule prodrug strategy and nanotechnology were integrated into one drug delivery system with
Periplocymarin, a cardiac glycoside isolated from Periploca sepium (P. sepium) and Periploca graeca (P. graeca), is a potential anti-cancer compound. The aim of the study was to investigate the potential for periplocymarin to interact with P-glycoprotein (P-gp) and to inhibit cytochrome P450s known
Periplocin is a cardiac glycoside and has been used widely in the clinic for its cardiotonic, anti-inflammatory and anti-tumor effects. Although it is taken frequently by oral administration in the clinic, there have been no reports demonstrating that periplocin could be detected in vivo after an
BACKGROUND
During a screening of Chinese plants traditionally used for the treatment of cancer and related diseases, extracts of the root bark of Periploca sepium Bunge showed strong cytotoxic activity.
OBJECTIVE
Isolate and identify cytotoxic compounds from P. sepium and investigate the effects and
OBJECTIVE
Cardenoliddes are steroid glycosides which are known to exert cardiotonic effects by inhibiting the Na(+)/K(+)-ATPase. Several of these compounds have been shown also to possess anti-tumor potential. The aim of the present work was the characterization of the tumor cell growth inhibition
