Gambogic acid (GA) is a naturally derived potent anticancer agent with extremely poor biocompatibility. In the present study, a novel of redox/pH dual-responsive multifunctional magnetic complex micelle (sPEG/HA/CSO-SS-Hex/Fe3O4/GA), which consisted of a reducible hexadecanol-modified chitosan
Marine organisms are an important source of chemical compounds which are appropriate for use as therapeutic agents. Among them, Sea pens produce valuable chemical compounds being used as anti-cancer drugs. The aim of this study was to investigate anti-cancer property of extracted and purified
Gambogic acid (GA) is a natural anti-tumor drug whose application is restricted by its poor aqueous solubility and inefficient bioavailability. Developing nanomaterials with excellent biocompatibility can amplify the therapeutic effects of GA. In this study, a tumor-targeted redox controllable
An antitumor drug/esophagus stent combination can palliatively relieve malignant esophageal stricture and exert local chemotherapy to cancer. It is vital for effective treatment of cancer to control drug release and facilitate drug penetration into deep tissue after the combination is placed in the
Background: SN38 (7-ethyl-10-hydroxy camptothecin), as a potent metabolite of irinotecan, is highly efficacious in cancer treatment. However, the clinical utility of SN38 has been greatly limited due to its undesirable properties, such as poor solubility and low stability. Materials and
Lipid-based delivery systems are an established technology with considerable clinical acceptance and several applications in human. Herein, we report the design, synthesis and evaluation of novel orthoester nucleoside lipids (ONLs) for the modulation of liposome stability. The ONLs contain head
A novel multifunctional hyaluronic acid-decorated redox-responsive magnetic complex micelle (HA/CSO-SS-Hex/Fe3O4/PTX) based on a reducible hexadecanol-modified chitosan oligosaccharide polymer micelle (CSO-SS-Hex) coated with hyaluronic acid (HA) and loaded with paclitaxel (PTX) Fe3O4 nanoparticles
High quality water-soluble semiconductor CdSe quantum dots (QDs) were prepared by a phase transfer method, in which amphiphilic oligomers (polymaleic acid aliphatic alcohol ester) was used as surface coating agents. The as-prepared aqueous QDs were high fluorescent and extremely stable. Fourier
Hexadecylphosphocholine is a new antitumour agent with a highly selective activity in chemically induced mammary tumours. It was suggested, that hexadecylphosphocholine is a pro-drug, cleavable by phospholipases C and/or D, creating hexadecanol or hexadecylphosphate as the active principle. To test
Hypericum riparium A. Chev. is a Cameroonian medicinal plant belonging to the family Guttiferae. Chemical investigation of the methanol extract of the stem bark of H. riparium led to the isolation of four natural products, 7,7'-dihydroxy-6,6'-biscoumarin (1), 7,7'-dihydroxy-8,8'-biscoumarin (2),
