They are characterized by a fluorine atom at the C-6 position, which distinguishes them from other quinolones. These antibiotics exhibit a broad spectrum of activity against Gram-negative and Gram-positive bacteria. 1. Classification of Fluoroquinolones Fluoroquinolones are synthetic antibacterial agents belonging to the broader category of antibiotics known as quinolones. The introduction of fluorine at the […]
Various species of bacteria, primarily actinomycetes, give rise to a class of antibiotics known as aminoglycosides. These antibiotics are characterized by their chemical structure, consisting of amino sugars connected by glycosidic linkages. They earn recognition for their broad-spectrum antibacterial activity, particularly against Gram-negative bacteria. Aminoglycosides play a crucial role in the treatment of serious bacterial […]
Cephalosporins are a group of broad-spectrum antibiotics that belong to the beta-lactam class. They are structurally and functionally related to penicillins, another group of antibiotics. Cephalosporins are derived from the fungus Acremonium (formerly known as Cephalosporium), and they exhibit antibacterial activity by interfering with the synthesis of bacterial cell walls. Classification of cephalosporins Cephalosporins are […]
Penicillins are a class of antibiotics with a common core structure known as a beta-lactam ring. They were the first antibiotics discovered and revolutionized the treatment of bacterial infections. Here’s an overview of penicillins: Chemical Structure Penicillins have a beta-lactam ring and are classified based on their side-chain structure. The basic structure consists of a […]
Chemotherapy is a crucial component of cancer treatment that involves the use of drugs to kill or inhibit the growth of cancer cells. Neoplastic diseases, commonly known as cancer, are characterized by uncontrolled cell division and the ability of cancer cells to invade surrounding tissues. Chemotherapy aims to target and eliminate these rapidly dividing cells […]
Chemotherapy refers to the use of drugs to treat diseases. In the context of infectious diseases, it involves antimicrobial agents to combat infections caused by bacteria, viruses, fungi, or parasites. Chemotherapy in infectious diseases aims to selectively target and eliminate the causative microorganisms while minimizing damage to the host’s cells. Basic Principles of Chemotherapy for […]
