Tuberculosis Resistance and Nanoparticles: Combating the Dual Role of Reactive Oxygen Species in Macrophages for Tuberculosis Management.

Increasing drift in antimicrobial therapy failure against Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), and the advent of extended resistant strains strongly demand discovery of mechanisms underlying development of drug resistance. The emergence of resistance against anti-TB drugs has reached an alarming level in various parts of the world, providing an active platform for the design of new targeted drug delivery. Reactive oxygen species (ROS) have an important role in controlling TB pathogenesis.

Folate-Functionalized Thiomeric Nanoparticles for Enhanced Docetaxel Cytotoxicity and Improved Oral Bioavailability.

To achieve remotely directed delivery of anticancer drugs, surface-decorated nanoparticles with ligands are reported. In this study, folic acid- and thiol-decorated chitosan nanoparticles loaded with docetaxel (DTX-NPs) were prepared for enhanced cellular internalization in cancer cells and improved oral absorption. The DTX-NPs were explored through in vitro and in vivo parameters for various parameters.

Advancements in the oral delivery of Docetaxel: challenges, current state-of-the-art and future trends.

The oral delivery of cancer chemotherapeutic drugs is challenging due to low bioavailability, gastrointestinal side effects, first-pass metabolism and P-glycoprotein efflux pumps. Thus, chemotherapeutic drugs, including Docetaxel, are administered via an intravenous route, which poses many disadvantages of its own. Recent advances in pharmaceutical research have focused on designing new and efficient drug delivery systems for site-specific targeting, thus leading to improved bioavailability and pharmacokinetics.
