The WTO was formed in 1995 and since then countries have abide by Trade Related Aspects of Intellectual Property Rights (TRIPS). The agreement provides for comprehensive plan for patenting and protection including those of medical supply units including vaccines and diagnosis. Recently developing countries such as India and South Africa have demanded TRIPS waiver for access to vaccines for all the developing countries The TRIPS waiver demanded, would apply to vaccines, diagnosis, and treatment related to COVID-19. The waiver is important as it would allow member state in researching, manufacturing, and supplying of vaccines.The proposal by the developing countries for temporary waiver of IP rights argues that IP could impede the supply of COVID-19 drugs and vaccines. However, there is no near consensus as most of the developed countries opposed this stance and they even argue that waiving TRIPS is not going to ramp up the manufacturing process. The pharmaceutical industry is also against this stance of developing countries, they put their argument forward that waiving of the IP will inhibit research and development of future prospects.
Quercetin is a well-known plant flavanol that exhibits multiple biological activities, including antioxidant, anti-inflammatory and anticancer activities. The role of quercetin in wound healing has been widely explored by a range of researchers in different models. However, the physicochemical properties, such as solubility and permeability, of this compound are low, which ultimately limits its bioavailability on the target site. To overcome these limitations for successful therapy, scientists have developed a range of nanoformulations that provide effective therapeutic potential. In this review, the broad mechanism of quercetin for acute and chronic wounds is covered. A compilation of recent advances on the horizon of wound healing via quercetin is incorporated with several advanced nanoformulations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
