porphyran and Neoplasms

Seaweeds are high in bioactive chemicals frequently used to treat human illnesses. Porphyran is a polysaccharide found in the red seaweeds of the genus Porphyra. Porphyran has been discovered to have immunomodulatory, anti-inflammatory activity, and anti-cancer effects via boosting immunity and targeting important apoptotic molecules, making them potential chemotherapeutic or chemopreventive drugs. Polysaccharide-mediated dynamic control of apoptosis and autophagy in cancer has been a viable treatment with low cytotoxicity with high efficacy. Thus, comprehending the influence of porphyran on human health and their molecular mechanisms would open up a new paradigm in cancer therapies. Also, the importance of apoptotic/autophagy modulating porphyran in cancer therapy has been highlighted as the future direction of improved nano-formulation for improved clinical efficacy. This review focuses on the current research into porphyran's anti-cancer efficacy and putative mechanisms of action through apoptosis and autophagy in various cancers, as well as its potential chemotherapeutic treatment in near future.

The hazardous effects of current nanoparticle synthesis methods have steered researchers to focus on the development of newer environmentally friendly and green methods for synthesizing nanoparticles using nontoxic chemicals. The development of environmentally friendly methods of nanoparticle synthesis with different sizes and shapes is one of the pressing challenges for the current nanotechnology. Several novel green approaches for the synthesis of AuNPs have been explored using different natural sources, such as plants, algae, bacteria, and fungi. Among organisms, algae and blue-green algae are of particular interest for nanoparticle synthesis. Gold nanoparticles (AuNPs) have a range of applications in medicine, diagnostics, catalysis, and sensors because of their significant key roles in important fields. AuNPs have attracted a significant interest for use in a variety of applications. The widespread use of AuNPs can be accredited to a combination of optical, physical, and chemical properties as well as the miscellany of size, shape, and surface composition that has been adopted through green synthesis methods.
