N-succinyl-chitosan (Suc-Chi) has favourable properties as a drug carrier such as biocompatibility, low toxicity and long-term retention in the body. It was long retained in the systemic circulation after intravenous administration, and the plasma half-lives of Suc-Chi (MW: 3.4 x 10(5);
Sequences encoding the transmembrane domain of the Rous sarcoma virus envelope (Env) glycoprotein were deleted and replaced with sequences that signal addition of a glycosyl phosphatidylinositol (GPI) membrane anchor. Stable NIH 3T3 cell lines expressing either the wild-type transmembrane-anchored
The antitumor activity of hot-water extract of delipidated BCG was investigated in mice inoculated with Sarcoma-180 cells and Ehrlich carcinoma cells, respectively. The hot-water extract was found to be effective when administered after and ineffective when administered before the inoculation of
Elfvingia applanata, a medicinal mushroom belonging to Basidiomycota, has been used in the effort to cure cancers of the esophagus and stomach, and is also known to have inhibitory effects on hepatitis B virus infection. The hot water soluble fraction (as Fr. HW) was extracted from fruiting bodies
The honeybee product propolis and its extracts are known to have biological effects such as antibiotic, anti-viral, anti-inflammatory and anti-tumor activities. This study was designed to investigate whether water-soluble propolis (WSP) inhibits tumor growth. The tumor cell line used was mouse
The carcinogenicity of quinoline was examined by administrating quinoline in the drinking water to groups of 50 F344/DuCrj rats and 50 Crj: BDF1 mice of each sex. In rats, the doses of quinoline were 0, 200, 400, and 800 ppm for males and 0, 150, 300, and 600 ppm for females. In male rats,
A water-soluble polysaccharide named as AMP was isolated and purified from the leaves of Ampelopsis megalophylla by DEAE-52 Cellulose and Sephadex G-100 column chromatography. AMP had an average molecular weight of about 8.4 × 10(4)Da and was composed of galactose (Gal), mannose (Man), glucose
In order to improve the deposition of mitomycin C (MMC) in the administered site, water-insoluble mitomycin C-albumin conjugate (MMC-G-BSA) was prepared. MMC was covalently attached to the glutarylated bovine serum albumin (G-BSA) in the presence of 1-ethyl-3-(3-dimethyl-aminopropyl) carbodiimide
The synthesis of novel substituted gold(III) tetraarylporphyrins with aqueous solubility has been carried out. The analogs ClAuTPP(CH(3)Py(+)·I(-)), ClAuTCPPNa, ClAuTPPCO(2)Na, ClAuTSPPNa and ClAuTPPNH(2)·HCl were evaluated for their in vitro cytotoxic activity against sarcoma 180 mouse tumor and
The biological activity of a hot-water extract from delipidated BCG, designated as HSA (Hot-water Soluble Adjuvant), was investigated. The HSA did not induce hyperreactivity to bacterial endotoxin. The hot-water extract from which nucleic acids had been removed by streptomycin (SM-HSA) was found to
The water-soluble polysaccharides from Cassia angustifolia L. leaves were isolated and fractionated. The acidic polysaccharide fraction was separated into two subfractions S1 and S2 consisting of L-rhamnose, L-arabinose, D-galactose, and D-galacturonic acid. Further fractionation of the predominant
To develop a water-soluble and tumor-targeted photosensitizer for photodynamic therapy (PDT), a porphyrin framework containing the metal ion gallium(III) was combined with platinum(II)-based groups to produce two new pentacationic metalloporphyrinates, Ga-4cisPtTPyP
Paclitaxel (PTX) is an antitumor agent for the treatment of various human cancers. Cremophor EL and ethanol are used to formulate PTX in commercial injection solutions, because of its poor solubility in water. However, these agents cause severe allergic reaction upon intravenous administration. The
