Abstract
Bioactive natural products are frequently glycosylated with saccharide chains of variable length. These sugars are important for the biological activity of the compounds and they contribute to the interaction with the biological target. The increasing knowledge of sugar biosynthesis pathways and the isolation of a large number of sugar gene clusters from antibiotic-producing actinomycetes are providing tools for combinatorial biosynthesis approaches that can generate potentially improved derivatives with altered sugars in their architecture. Novel derivatives of known bioactive natural products can be produced either in the producer organisms or in heterologous hosts by using different combinatorial biosynthesis strategies. In this article, recent advances in the field are discussed, illustrating the alternative approaches of gene inactivation, gene expression, combining gene inactivation and gene expression, co-expression of genes from different pathways or the use of sugar cassette plasmids to endow a host with the capability of synthesizing new sugars.

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
Drug Discovery in the Age of Artificial Intelligence
In the age of artificial intelligence (AI), we have witnessed a significant boom in AI techniques for drug discovery. AI techniques are increasingly integrated and accelerating the drug discovery process. These developments have not only attracted the attention of academia and industry but also raised important questions regarding the selection ...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
