Pharmaceutical formulations targeting specific regions of the gastrointesinal tract
Oral formulations of pharmaceuticals are provided with enhanced bioavailability by targeting specific regions of the gastrointestinal tract. Particularly, water soluble and acid-labile drugs such as cytidine analogs (e.g., decitabine) and 2'-deoxyadenosine analogs (e.g., pentostatin) are formulated with pH-sensitive polymers so that these drugs are preferably absorbed in the upper regions of the small intestine, such as the jejunum. In addition, drugs with poor oral bioavailability such as camptothecin compounds (e.g., 9-nitro-camptothecin) can also be formulated using similar strategies in order to significantly improve their oral bioavailability. These formulations can be used to treat a wide variety of diseases or conditions, such hematological disorders, benign tumors, cancer, restenosis, inflammatory diseases, and autoimmune diseases.

Curcumin cyclodextrin combination for preventing or treating various diseases
Curcumin has shown anti-inflammatory and anti-angiogenic properties that could be useful in treating various diseases such as those of rheumatology and oncology. However, curcumin is very poorly absorbed and has a very low bioavailability. This patent describes a method of increasing the delivery of curcumin by complexing it with cyclodextrins. Cyclodextrins are well known in the food industry and have been used to carry other drugs to increase bioavailability. The new combination of cyclodextrins and curcumin has been tested in pre-clinical inflammation models where it has demonstrated efficacy superior to both the positive control and curcumin.

The entire substance of the matrix, all the surfaces and the pores and / or nanochannels comprise a plurality of silanol (Si—OH) and quaternary ammonium functional groups. The bioavailability of a negatively charged bioactive compound can be increased by loading it into the pores and / or nanochannels. The silanol (Si—OH) functional groups on the surfaces lining the walls of the pores and / or nanochannels are free to deprotonate in a fluid having pH above the pI of the positively charged MSN and lead to a sustained release of the negatively charged drug from the pores and / or nanochannels, and thereby enhance the bioavailability of the drug.

Micelle encapsulation of therapeutic agents
ActiveUS20110076308A1Effective dissolutionToxic reductionBiocideDispersion deliveryLarge doseActive agent
The invention provides active agents, such as paclitaxel, rapamycin, or 17-AAG, encapsulated by safe poly(ethylene glycol)-block-poly(lactic acid) (“PEG-b-PLA”) micelles. The compositions provide effective solubilization of drug combinations, such as paclitaxel, rapamycin, and 17-AAG, as well as others described herein. A significant advantage of PEG-b-PLA as a carrier is that it is less toxic than Cremophor® EL or DMSO, which are used in currently known compositions. Additionally, PEG-b-PLA micelles are easier to handle than DMSO and they do not possess a foul odor, which is a problem with formulations currently in clinical trials. Accordingly, the invention provides stable and biocompatible drug formulations that improve bioavailabilty without causing toxicity. It was also found that larger doses of individual drugs in micelle formulations can be administered compared to non-micelle formulations.
