- Nanocarriers in Tuberculosis treatment: Challenges and delivery strategiesPublication . Kumar, Mahesh; Virmani, Tarun; Kumar, Girish; Deshmukh, Rohitas; Sharma, Ashwani; Duarte, Sofia; Brandão, Pedro; Fonte, PedroThe World Health Organization identifies tuberculosis (TB), caused by Mycobacterium tuberculosis, as a leading infectious killer. Although conventional treatments for TB exist, they come with challenges such as a heavy pill regimen, prolonged treatment duration, and a strict schedule, leading to multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains. The rise of MDR strains endangers future TB control. Despite these concerns, the hunt for an efficient treatment continues. One breakthrough has been the use of nanotechnology in medicines, presenting a novel approach for TB treatment. Nanocarriers, such as lipid nanoparticles, nanosuspensions, liposomes, and polymeric micelles, facilitate targeted delivery of anti-TB drugs. The benefits of nanocarriers include reduced drug doses, fewer side effects, improved drug solubility, better bioavailability, and improved patient compliance, speeding up recovery. Additionally, nanocarriers can be made even more targeted by linking them with ligands such as mannose or hyaluronic acid. This review explores these innovative TB treatments, including studies on nanocarriers containing anti-TB drugs and related patents.
- Transforming cancer treatment: the potential of nanonutraceuticalsPublication . Kumar, Girish; Virmani, Tarun; Chhabra, Vaishnavi; Virmani, Reshu; Pathak, Kamla; Akhtar, Md Sayeed; Asim, Mulazim Hussain; Arshad, Shumaila; Siddique, Farzana; Fonte, PedroChemotherapy in the management of cancer is constrained by limitations like off-target effects, poor bioavailability, and dose-dependent toxicity. Nutraceuticals have been explored as an innovative strategy to overcome chemotherapy drawbacks. However, the clinical utility of nutraceuticals is restricted due to their complex structures, less water solubility, reduced stability, decreased bioavailability and more obstacles in the gastrointestinal tract. Nanonutraceuticals are nanosized nutraceutical particles having enhanced solubility, improved bioavailability, stability, and targeted delivery to specific cells. Nutraceuticals can be co-delivered with other chemotherapeutic drugs in nanocarriers to elicit synergistic effects. The targeting of nutraceuticals against cancer cells can be enabled by coupling ligands with the nanocarriers, which direct to the overexpressed receptors found at the surface of the cancer cells. Transitioning a nanonutraceutical from pre-clinical research to clinical trials is a pivotal step. This focus on advancing their application holds great potential for impacting clinical research and improving the treatment landscape for cancer patients. This review focuses on the role of nutraceuticals for cancer treatment, various nanocarriers for the efficient delivery of nutraceuticals along with co-administration of nutraceuticals with chemotherapeutic drugs using nanocarriers. Also, emphasize the targeting of ligands coupled nanocarriers to the cancer cells along with patents and clinical trials for nanonutraceuticals.
