ABSTRACT
Natural compounds such as polyphenols play several positive roles in maintaining the oxidative and inflammatory capacity of cells, which leads to their potential use as anticancer therapeutics. There is promising evidence for the in vitro and in vivo anticancer activity of many polyphenols, including resveratrol and quercetin, specifically in the treatment of colorectal cancer (CRC). There is a clear association between resveratrol and quercetin in interfering with the mechanistic pathways involved in CRC, such as Wnt, P13K/AKT, caspase-3, MAPK, NF-κB, etc. These molecular pathways establish the role of resveratrol and quercetin in controlling cancer cell growth, inducing apoptosis, and inhibiting metastasis. The major bottleneck in the progression of the use of resveratrol and quercetin as anticancer therapeutics is their reduced bioavailability in vivo because of their rapid metabolism in humans. Recent advancements in various nanotechnological formulations are promising for overcoming these bioavailability issues. Various nanoformulations of resveratrol and quercetin have shown an optimistic impact on reducing the solubility and improving the stability of resveratrol and quercetin in vivo. A combinatorial approach using nanoformulations of resveratrol with quercetin could potentially increase the impact of resveratrol in controlling CRC cell proliferation. This review discusses the mechanism of resveratrol and quercetin, the two bioactive polyphenolics, in colon cancer, with an emphasis on various types of nanoformulations of the two molecules targeting colon cancer. It also explores the synergistic effect of combining resveratrol and quercetin in various nanoformulations, targeting colon cancer. This research delves into the enhanced pharmacokinetics and potential chemotherapeutic benefits of these bioactive polyphenolics when used together in innovative ways.
ABSTRACT
The significance of Autoimmune Disorders (Ads) is underscored by their chronic nature, high maintenance costs, and complexity affecting numerous organs and tissues. A more comprehensive approach to treating Ads is required across patient populations. A revolutionary area for obtaining an integrated therapeutic option is natural phytoconstituents. Diverse biomolecules with promising properties can be found in abundance in the marine environment. Many substances have been identified from sponges, bacteria, fungi, cyanobacteria, and algae that have been shown to have immunomodulatory activities and may be used as possible treatments for Ads. Marine-derived bioactive substances have been demonstrated to affect immunological responses and to be essential in immunotherapies. The amount of information about the specific effects of substances obtained from marine sources utilized as dietary supplements or for treating immune-related diseases is growing. This paper discusses many sources of potential marine metabolic chemicals, such as maritime flora and fauna. Numerous marine phytoconstituents have recently been isolated, described, and identified, and they are currently undergoing human usage studies. We have attempted to consolidate information concerning phytoconstituents from marine sources with anti-inflammatory and immunomodulatory properties in this review, and we have briefly explored their methods of action. In order to provide a baseline of knowledge for promoting marine flora-based phytoconstituents in the current context of increasing Ads incidence, deprived of the more affordable, safe, and effective medications to combat the terrible human disease, this paper reviews the works thus far conducted on this aspect.
