Penicillins Part 3 I β-Lactam Antibiotics | Chemotherapy I Pharmacology & Medicinal Chemistry

Lectures explains how penicillins inhibit bacterial cell wall synthesis and why they are highly effective against many Gram-positive and Gram-negative bacteria. The medicinal chemistry part focuses on the β-lactam ring, thiazolidine ring, side chain modifications, and development of semisynthetic penicillins. Topics Covered in Lecture Series • Introduction to β-lactam antibiotics • Discovery and history of Penicillin • Chemical structure of penicillins • Mechanism of action – inhibition of bacterial cell wall synthesis • Structure-Activity Relationship (SAR) of penicillins • Classification of penicillins • Natural penicillins • Penicillinase-resistant penicillins • Aminopenicillins • Extended-spectrum penicillins • Pharmacological actions and spectrum of activity • Resistance mechanisms (β-lactamase production) • Clinical uses and therapeutic applications • Important examples: Penicillin G, Penicillin V, Ampicillin, Amoxicillin, Methicillin This lecture will help students build strong conceptual clarity in antimicrobial chemotherapy and medicinal chemistry, which are frequently asked topics in GPAT, NIPER, and university examinations. Who Should Watch • GPAT Aspirants • NIPER Preparation • B.Pharm Students • M.Pharm Students • Pharmaceutical Chemistry Students • Pharmacology Students
