Enhanced oral bioavailability and antitumor therapeutic efficacy of sorafenib administered in core-shell protein nanoparticle.

Orally delivered molecularly targeted small-molecule drugs play a significant role in managing cancer as a chronic disease. However, due to the poor oral bioavailability of some of these molecules, high-dose administration is required leading to dose-limiting toxicity especially when delivered daily for a long duration. Here, we report an oral nanoformulation for small-molecule multi-kinase inhibitor, sorafenib tosylate, showing nearly two fold enhancement in the oral bioavailability and enhanced therapeutic efficacy with a better safety profile compared to the current clinical formulation.

Encapsulation and Protection of Omega-3-Rich Fish Oils Using Food-Grade Delivery Systems.

Regular consumption of adequate quantities of lipids rich in omega-3 fatty acids is claimed to provide a broad spectrum of health benefits, such as inhibiting inflammation, cardiovascular diseases, diabetes, arthritis, and ulcerative colitis. Lipids isolated from many marine sources are a rich source of long-chain polyunsaturated fatty acids (PUFAs) in the omega-3 form which are claimed to have particularly high biological activities. Functional food products designed to enhance human health and wellbeing are increasingly being fortified with these omega-3 PUFAs because of their potential nutritional and health benefits.
