a controlled release matrix formulation for mesalamine was designed and developed to achieve a 24 h release profile. using compritol 888 ato (glyceryl behenate) as an inert matrix-forming agent to control the release of mesalamine, formulation granules containing the solid dispersions were investigated. pectin, a polysaccharide, was used as bacterial dependent polymer for colon targeting. the m...

Objective(s): This study is aimed to design and synthesize a prodrug of 5-aminosalicylic acid and evaluate its ameliorative effect on experimental ulcerative colitis (UC).Materials and Methods: 5-Aminosalicylic acid-alanine (5-ASA-ALA) was synthesized and characterized. Its stability study was conducted in rat plasma and in the gastroint...

the present investigation was aimed at developing a novel colon targeted system of lornoxicam based on the use of a combination of ph dependent system (to prevent the premature release of drug in the upper git) and enzymatically degradation system (to ensure the specificity of drug release in the colon). the drug loaded guar gum microspheres prepared by emulsification cross-linking method were ...

Nanomedicines In article 2201140 by Hsin-Cheng Chiu and co-workers, an oral polysaccharide microgel formulation containing dual-modality therapeutic nanoparticles developed for local treatment of colon cancer is imparted to hierarchical targeting residues, leading increases in retention cell uptake nanotherapeutics. With enzymatic degradation dextran microgels occurring exclusively the colon, n...

background: immunotoxins are comprised of both the cell targeting and the cell killing moieties. we previously established a new immunotoxin, i.e. shiga toxin granulocyte macrophage-colony stimulating factor (stxa1-gm-csf), comprises of catalytic domain of stx, as a killing moiety and gm-csf, as a cell targeting moiety. in this study, the ability of the immunotoxin to induce apoptosis and doubl...

conclusions traf6 plays an important role in the onset of colon cancer; therefore, drugs targeting it may have great clinical significance in the treatment of this disease. results the positive expression rate of traf6 in tumor tissues was 66.7%, which was significantly higher than in normal paracancerous tissues (18.5%). the positive expression rate of traf6 was significantly correlated with d...

Background: Immunotoxins are comprised of both the cell targeting and the cell killing moieties. We previously established a new immunotoxin, i.e. Shiga toxin granulocyte macrophage-colony stimulating factor (StxA1-GM-CSF), comprises of catalytic domain of Stx, as a killing moiety and GM-CSF, as a cell targeting moiety. In this study, the ability of the immunotoxin to induce apoptosis and dou...

The oral route is the preferred route for drug delivery, among oral delivery Intestine and colon drug delivery have been used for molecules aimed at local treatment of colonic diseases such as Colon Cancer, Polyp, Colorectal, Crohn’s Disease, Inflammatory Bowel Disease (IBD), Ulcerative Colitis (UC) etc. and for delivery of molecules susceptible to enzymatic degradation such as peptides. There ...
