The latest advancements in cellulose and its derivatives are the subject of this study. We summarize the characteristics, modifications, applications, and properties of cellulose. Here, we discuss new breakthroughs in modified cellulose that allow for enhanced control. In addition to standard approaches, improvements in different techniques employed for cellulose and its derivatives are the subject of this review. The various strategies for synthetic polymers are also discussed. The recent advancements in polymer production allow for more precise control, and make it possible to make functional celluloses with better physical qualities. For sustainability and environmental preservation, the development of cellulose green processing is the most abundant renewable substance in nature. The discovery of cellulose disintegration opens up new possibilities for sustainable techniques. Based on the review of recent scientific literature, we believe that additional chemical units of cellulose solubility should be used. This evaluation will evaluate the sustainability of biomass and processing the greenness for the long term. It appears not only crucial to dissolution, but also to the greenness of any process.

Historically, natural plant-derived drugs received a great impact of consideration in the treatment of several human-associated disorders. Cancer is a devastating disease and the second most cause of mortality. Sanguinarine (SANG), a naturally isolated plant alkaloidal agent, possesses chemo-preventive effects. Several studies have revealed that SANG impedes tumor metastasis and development by disrupting a wide range of cell signaling pathways and its molecular targets, such as BCL-2, MAPKs, Akt, NF-κB, ROS, and microRNAs (miRNAs). However, its low chemical stability and poor oral bioavailability remain key issues in its use as a medicinal molecule. A novel method (e.g., liposomes, nanoparticles, and micelles) and alternative analogs provide an exciting approach to alleviate these problems and broaden its pharmacokinetic profile. Cancer-specific miRNA expression is synchronized by SANG, which has also been uncertain. In this critical study, we review the utilization of SANG mimics and nano-technologies to improve its support in cancer. We focus on recently disclosed studies on SANG anti-cancer properties.
