A new adamantane derivative N,N'-bis (ethylene)P(1-adamantyl)-phosphonis diamide, was found to inhibit Rous sarcoma virus replication in much the same manner as reported for the parent compound, 1-adamantanamine hydrochloride.

Ethylene glycol monomethyl ether (EGME) is a major component of paints, lacquers, inks, and automobile brake fluids. As a result, exposures to humans are inevitable. We therefore, investigated in this study, its effect on testicular cells in a time-course manner in male Wistar rats. Animals were

The 5'-γ-ferrocenyl adenosine triphosphate (Fc-ATP) bioconjugates (3 and 4), containing the poly(ethylene glycol) spacers, were synthesized and compared to a hydrophobic analogue as co-substrates for the following protein kinases: sarcoma related kinase (Src), cyclin-dependent kinase (CDK), casein

Intravenous injection of the gallium chelating agents, N,N'-ethylene bis[2-hydroxy-5-carboxyphenyl-glycine], (COOH-EHPG), or desferrioxamine (DFO) after gallium-67 (67Ga) injection, improved tumour/non-tumour tissue uptake ratios in mice bearing the EMT-6 sarcoma. Six hours post injection of gallium

In this study, a novel amphiphilic block copolymer biomaterial - poly (ethylene glycol)-poly (caprolactone) (PEG-PCL), was used to entrap norcantharidin (NCTD), taking advantage of self-assembly theory. Dialysis and volatilization dialysis were used to prepare copolymer micelles. Drug-loaded

During an investigation of the role of ions in growth regulation, it was found that ethylene diamine tetraacetate (EDTA) inhibits DNA synthesis about 10-fold in cultures of chick embryo cells, while ethylene glycol bis(beta-amino ethyl ether)-N,N'-tetraacetate has no effect. RNA synthesis is only

BACKGROUND Kaposi sarcoma (KS) has features of both neoplastic growth and hyperplastic proliferation. It is the most common tumor seen in patients with HIV infection. Whether KS is a real tumor or a benign hyperplastic disease is not known. METHODS Tissues from KS and cutaneous hemangioma lesion DNA

Irinotecan-containing nanoparticles (NP) were prepared by coprecipitation with addition of water to acetone solution of poly(DL-lactic acid), poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) and irinotecan, and subsequent evaporation of organic solvent. NP were purified

Pegylated-liposomal doxorubicin (Doxil) is a unique form of liposomal doxorubicin in which the liposomes are coated with methoxypoly (ethylene glycol), resulting in a diminished uptake by the reticuloendothelial system, leading to a longer half-life in blood and a different toxicity profile than

A series of hybrid di-block copolymers of poly(l- glutamic acid-b-l- leucine) (PGA-PLeu), methoxy poly (ethylene glycol)-b-poly(l-leucine) (PEG-PLeu), methoxy poly(ethylene glycol)-b-poly(γ-benzyl-l-glutamic acid) (PEG-PBLG) and tri-block copolymers of poly(ethylene glycol)-b-poly(l-glutamic

Well-defined poly(ethylene glycol)-b-allyl functional polylactide-b-polylactides (PEG-APLA-PLAs) are synthesized through sequential ring-opening polymerization. PEG-APLA-PLAs that have amphiphilic properties and reactive allyl side chains on their intermediate blocks are successfully transferred to

A series of 4-substituted 2-formylpyridine thiosemicarbazones has been synthesized which contain a tertiary N at the 4 position. These materials were obtained by reacting 4-nitro-2-picoline N-oxide, either directly or after conversion to the corresponding 4-chloro derivative, with a variety of

This study is aimed at extending a thermo-induced physical hydrogel as a localized delivery system of the antitumor drug doxorubicin (DOX). An amphiphilic triblock copolymer consisting of poly(lactic acid-co-glycolic acid) (PLGA) and poly(ethylene glycol) (PEG) was synthesized. The PLGA-PEG-PLGA
