Antioxidant micelles capable of scavenging reactive oxygen species (ROS) are prepared from poly(ethylene glycol)-b-poly(dopamine) block copolymers. The micelles inhibit tube formation of human umbilical vein endothelial cells (HUVECs) by scavenging endogenous ROS. Furthermore, the micelles inhibit angiogenesis in the chicken

Nanoparticles (NP) that target bone tissue were developed using PLGA-PEG (poly(lactic-co-glycolic acid)-polyethylene glycol) diblock copolymers and bone-targeting moieties based on aspartic acid, (Asp)(n(1,3)). These NP are expected to enable the transport of hydrophobic drugs. The molecular structures were examined by

Alkoxide-bridged disilver cations react with dihydrogen to form hydride-bridged cations, releasing free alcohol. Hydrogenolysis of neutral silver fluorides affords hydride-bridged disilver cations as their bifluoride salts. These reactions proceed most efficiently when the supporting ligands are expanded N-heterocyclic carbenes (NHCs)

The purpose of the present study was to design and fabricate endosomal pH-sensitive dual-ligand-modified micellar nanoparticles to achieve enhanced drug delivery to tumor cells and facilitated intracellular drug release. End-group-carboxylated poly(2-ethyl-2-oxazoline)-poly(D,L-lactide) and cyclic Arg-Gly-Asp-Tyr-Lys- and anti-prostate specific membrane antigen antibody-modified

Poly(ethylene glycol)-b-poly(caprolactone) (PEG-b-PCL) micelles dually loaded with both pheophorbide a (PhA) as a photosensitizer and β-carotene (CAR) as a singlet oxygen ((1)O2) scavenger were designed to control photodynamic therapy (PDT) activity in cancer treatment. The CAR in the PhA/CAR micelles

An attractive approach to reduce the undesired side effects of bone morphogenetic proteins (BMPs) in regenerative medicine is to use osteoinductive peptide sequences derived from BMPs. Although the structure and function of BMPs have been studied extensively, there is limited

Drug-induced liver injury (DILI) is a significant concern in drug development due to the poor concordance between preclinical and clinical findings of liver toxicity. We hypothesized that the DILI types (hepatotoxic side effects) seen in the clinic can be translated

Integrins are associated with tumour cell survival and progression, and their expression has been shown to be increased in tumours. Thus, four novel conjugates of the tripeptide integrin ligand Arg-Gly-Asp (RGD) and the cytotoxic agent paclitaxel (cRGD-PTX) were prepared to

Prodrug micelles carrying 5-(4-hydroxyphenyl)-3H-1,2-dithiole-3-thione (ADT-OH), a compound possessing chemopreventive properties, are prepared from amphiphilic block copolymers linking ADT-OH via an ester bond using glycine (PAM-PGlyADT) and isoleucine linkers (PAM-PIleADT). The release of ADT-OH from the PAM-PIleADT micelles is much slower

We describe a protocol for the synthesis of mono-6-amino-6-deoxy-cyclodextrin hydrochloride (CD-NH3Cl), applicable to alpha-, beta- and gamma-cyclodextrin. These structurally simplest, highly water-soluble cationic cyclodextrins can be widely used in molecular recognition, chiral separation and drug delivery studies. Starting from commercially
