Marine algae have long been utilised as food and medicine and are crucial to the ecology. Marine creatures have the potential to be abundant sources of highly bioactive secondary metabolites that could serve as valuable starting points for the creation of novel pharmaceuticals. The sea is regarded as the largest remaining pool of natural molecules to be assessed for therapeutic activity and provides a tremendous resource for novel compounds due to the fact that marine animals make up around half of all species in the world. It is a real fact that the importance of marine organisms as a source of new substances is growing. Algae can be divided into two primary categories: macroalgae (seaweeds), which includes green, brown, and red algae, and microalgae, which includes blue-green algae, dinoflagellates, bacillariophyta (diatoms), etc. The natural bioactive compounds found in marine algae have been demonstrated to be a rich source of anti-diabetic, anti-inflammatory, antiviral, antifungal, hypolipidemic, antioxidant, anti-hypercholesterolemia, antibacterial, and antineoplastic activities. They generate fresh secondary metabolites with potential for use as pharmaceuticals because of their biological activity. The potential pharmacological, therapeutic, and research applications of these substances have been covered in this review.

Introduction An important and reliable source of effective therapeutic leads that come from Earth’s biodiverse flora and fauna are natural substances generally referred to as "secondary metabolites" (the end-products of gene expression). 1 A wide range of biological sources, including both prokaryotic (eubacteria, 92 cyanobacteria), and eukaryotic species, have allowed for the identification of more than 30,000 chemicals of marine origin over the course of five decades of persistent investigation (fungi, dinoflagellates, algae, sponges, cnidarians, bryozoans, 93 mollusks, ascidians, and echinoderms). 2,3 The Earth’s oceans, which cover * Corresponding author.

In recent decades, a multitude of novel compounds have been unearthed from marine organisms, displaying intriguing pharmaceutical properties. This has led to the acknowledgment of marine organisms as promising candidates not only for the derivation of new bioactive substances for pharmaceutical advancement but also as a source of diverse biologically active compounds. Several bioactive metabolites have been uncovered through screening initiatives, originating from cyanobacteria and marine algae. These chemical entities exhibit a broad spectrum of biological activities and possess varied chemical structures, garnering interest from biopharmaceutical enterprises.
