Abstract
Colorectal cancer is the most common cancer in Western countries and the second leading cause of cancerrelated death. Sporadic lesions represent 75-80% of all colorectal cancer, whereas 20-25% are in younger individuals or in patients with a family history of cancer, suggesting a heritable susceptibility. Persons with germline alterations in cancerpromoting genes, such as those with familial adenomatous polyposis and hereditary non-polyposis colorectal cancer, stand to benefit significantly from chemopreventive interventions, along with those who had already developed any colorectal neoplasia (either adenoma or carcinoma). Among the most promising approaches to chemoprevention is the use of nonsteroidal anti-inflammatory drugs, including both selective and non-selective cyclooxigenase-2 inhibitors. Although the present article is mainly focused on these drugs and their mechanisms of action, other strategies with potential involvement in colorectal cancer chemoprevention such as peroxisome proliferator activated receptor ligands, epithelial growth factor receptor blockers, calcium, vitamin D, folate, and DNA methyltransferase inhibitors are also reviewed.

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
