Abstract
Owing to their inherent structural features, certain sulfated glycans isolated from terrestrial or marine mammals or invertebrates, can exert therapeutic properties against infections caused by pathogenic microorganisms like bacteria, virus, fungus, and protozoan parasites. These sulfated glycans belong to a variety of classes including glycosaminoglycans (GAGs) like chondroitin sulfate, fucosylated chondroitin sulfate, dermatan sulfate, unfractionated heparin, low-molecular-weight heparin, and acharan sulfate; and the less-famous algal polysaccharides known as sulfated fucans (including fucoidans), sulfated galactans (agarans and carrageenans), and sulfated heteropolysaccharides. Administration at certain concentrations of the antimicrobial sulfated glycans, especially those containing the higher amounts of the bioactive structural requirements, can lead to the interruption or disruption of the pathogen protein-host GAG complex formation, leading thus to the decrease or impairment of the microbial binding onto host cells. This report aims at presenting the current background concerning the therapeutic effects of the above-mentioned sulfated glycans as new antimicrobial agents. When sufficient data are available, discussion regarding structure-activity relationship is provided.

Chemistry Based on Natural Products for Therapeutic Purposes
The development of new pharmaceuticals for a wide range of medical conditions has long relied on the identification of promising natural products (NPs). There are over sixty percent of cancer, infectious illness, and CNS disease medications that include an NP pharmacophore, according to the Food and Drug Administration. Since NP ...read more
Current Trends in Drug Discovery Based on Artificial Intelligence and Computer-Aided Drug Design
Drug development discovery has faced several challenges over the years. In fact, the evolution of classical approaches to modern methods using computational methods, or Computer-Aided Drug Design (CADD), has shown promising and essential results in any drug discovery campaign. Among these methods, molecular docking is one of the most notable ...read more

From Biodiversity to Chemical Diversity: Focus of Flavonoids
Flavonoids are the largest group of polyphenols, plant secondary metabolites arising from the essential aromatic amino acid phenylalanine (or more rarely from tyrosine) via the phenylpropanoid pathway. The flavan nucleus is the basic 15-carbon skeleton of flavonoids (C6-C3-C6), which consists of two phenyl rings (A and B) and a heterocyclic ...read more
