We succeeded in purifying a major glycolipids fraction (i.e., Fraction-II) in the class of monogalactosyl diacylglycerol (MGDG), digalactosyl diacylglycerol (DGDG) and sulfoquinovosyl diacylglycerol (SQDG) from spinach using hydrophobic column chromatography. Fraction-II inhibited the activities of

Multiple intravenous injections (30 micrograms, ten times) in ICR mice of trehalose dimycolate and glucose monomycolate from Nocardia rubra, containing C36-48 mycolic acids, showed a prominent antitumor effect on a subcutaneously implanted sarcoma-180, an allogeneic sarcoma of mice with a

We succeeded in purifying the fraction of monogalactosyl diacylglycerol (MGDG), digalactosyl diacylglycerol (DGDG), and sulfoquinovosyl diacylglycerol (SQDG) containing the major glycolipids from a green vegetable, spinach (Spinacia oleraceaL.). This glycolipids fraction inhibited the activities of

Immunomodulatory glycolipids, among which α-galactosylceramide (KRN7000) is an iconic example, have shown strong therapeutic potential in a variety of conditions ranging from cancer and infection to autoimmune or neurodegenerative diseases. A main difficulty for those channels is that they often

We succeeded in purifying the fraction containing the major glycolipids in monogalactosyl diacylglycerol, digalactosyl diacylglycerol and sulfoquinovosyl diacylglycerol (SQDG) from dried vegetables. This glycolipids fraction was an inhibitor of DNA polymerase alpha (pol alpha) in vitro and also the

To reduce the side effects and drug resistance in cancer chemotherapy, we have examined the in vitro efficacy of the combination of paclitaxel (PTX) and doxorubicin (DOX) loaded in nanosized polymeric micelles with glycolipid-like structure, which formed by lipid grafted chitosan. The cytotoxicities

A monoclonal antibody, BLCA-8, was raised against the human bladder cancer cell line, UCRU-BL-17CL. By flow cytometry and immunoperoxidase staining, this antibody was found to possess high specificity for bladder tumours, some reactivity with fetal tissues, and no reactivity with normal bladder, or

We succeeded in purifying a major glycolipid fraction from a green vegetable, spinach. This fraction consists mainly of three glycolipids: monogalactosyl diacylglycerol (MGDG), digalactosyl diacylglycerol (DGDG), and sulfoquinovosyl diacylglycerol (SQDG). In a previous study, we found that the

AIM/ BACKGROUND: To determine the feasibility and safety of intratumoral α-gal glycolipids injection for conversion of human tumors into autologous Tumor Associated Antigens (TAA) vaccine. α-Gal glycolipids bind anti-Gal--the most abundant antibody in humans. Pre-clinical studies indicated that

alpha-Gal glycolipids capable of converting tumors into endogenous vaccines, have alpha-gal epitopes (Gal alpha 1-3 Gal beta 1-4GlcNAc-R) and are extracted from rabbit RBC membranes. alpha-Gal epitopes bind anti-Gal, the most abundant natural antibody in humans constituting 1% of immunoglobulins.

Previous work demonstrated that a subset of natural killer T cells in mice decreased the antitumor efficacy of live attenuated Listeria monocytogenes where the actin A and internalin B genes were genetically deleted (LMD) against murine hepatic colorectal cancer metastases. Therefore, we

Synthetic glycolipids prepared by esterification of various sugars and sorbitol, and containing various numbers of saturated or unsaturated fatty acid residues as well as bacterial lipid A and lipopolysaccharide, were tested for mitogenicity of splenic cells of Fischer rats and Swiss mice and for

Multi-cycle treatment strategies were frequently applied in anti-tumor therapy in clinic. However, numerous tumors developed drug resistance during this process, and few researches paid attention to the multi-cycle treatment process when a nano carrier was adopted. In this research, a

Ehrlich ascites tumor cells were incubated in vitro with rac-1-O-[1'-14C]octadecyl-2-O-methylglycero-3-beta-D-glucopyranosi de for 24 h. The potentially antineoplastic ether glycolipid was rapidly metabolized by the cells to radioactive 1-O-octadecyl-2-O-methylglycerol (70 pmol/10(6) cells per h)
