| 20080317666 | Colonic Delivery of Active Agents - Drug delivery devices that are orally administered, and that release active ingredients in the colon, are disclosed. In one embodiment, the active ingredients are those that inactivate antibiotics, such as macrolides, quinolones and beta-lactam containing antibiotics. One example of a suitable active agent is an enzyme such as beta-lactamases. In another embodiment, the active agents are those that specifically treat colonic disorders, such as Chrohn's Disease, irritable bowel syndrome, ulcerative colitis, colorectal cancer or constipation. The drug delivery devices are in the form of beads of pectin, crosslinked with calcium and reticulated with polyethyleneimine. The high crosslink density of the polyethyleneimine is believed to stabilize the pectin beads for a sufficient amount of time such that a substantial amount of the active ingredients can be administered directly to the colon. Advantageously, the amount of polyethyleneimine is sufficient to allow a substantial portion of the pectin beads to pass through the gastrointestinal tract to the colon without releasing the active agent, and is also sufficient such that the pectin beads are sufficiently degraded in the colon to release an effective amount of the active agent. | 12-25-2008 |
| 20090130214 | Gemcitabine derivatives nanoparticles - The invention concerns a 2′,2′-difluoro-2′-deoxycytidine derivative of general formula (I), wherein: R | 05-21-2009 |

| 20100160249 | NANOPARTICLE DERIVATIVES OF GEMCITABINE - The use of squalenic acid or a derivative thereof in formulating at least one polar active principle with a molecular weight of 100 Da or more, in the form of nanoparticles, and pharmaceutical compositions thereof. | 06-24-2010 |
| 20100226991 | SOLID INORGANIC/ORGANIC HYBRID WITH MODIFIED SURFACE - The invention relates to solid organometallic hybrids with modified surface. Said solid may be used for example for the encapsulation and vectoring of molecules of interest such as active pharmaceutical agents, compounds of interest in cosmetics and markers, for example, contrast agents. Said solids show good results in terms of loading capacity in medicament agents and in biocompatibility. | 09-09-2010 |
| 20100305030 | NANOPARTICLES OF THERAPEUTIC AGENTS HAVING LOW WATER SOLUBILITY - The invention relates to a water-dispersible derivative of a therapeutic agent having a low water solubility that comprises at least one molecule of said agent covalently bonded to at least one molecule of a hydrocarbon derivative having a squalenic structure or the like. The invention further relates to corresponding nanoparticles. | 12-02-2010 |
