Lead discovery based on clinical observation harnesses real-world patient findings—case reports, adverse-event signals, and unexpected therapeutic effects—to identify new drug leads and repurposing opportunities. This approach integrates pharmacovigilance, phenotypic evidence, translational research, and medicinal chemistry to transform clinical signals into testable hypotheses. B.Pharm students should grasp methods for signal detection, causality assessment, preclinical validation, ADME/Tox … Read more

Drug metabolism is central to lead discovery because metabolic stability, bioactivation and ADME determine a candidate’s safety and efficacy. This concise, keyword-rich set of MCQs for B. Pharm students explores phase I and II reactions, major CYP450 isoenzymes, in vitro models (microsomes, hepatocytes), metabolite identification by LC-MS/MS, IVIVE and PBPK concepts, drug–drug interactions, genetic polymorphisms, … Read more

Introduction: This concise set of 30 MCQs on serendipitous drug discovery examples is designed for B. Pharm students to deepen understanding of drug discovery, serendipity, pharmacology, and medicinal chemistry. The questions cover classic case studies—penicillin, sildenafil (Viagra), minoxidil, chlorpromazine, cisplatin, warfarin, lithium—and probe mechanisms, historical context, safety lessons, and implications for drug repurposing. You will … Read more

Non-random screening methods are targeted strategies used in pharmaceutical screening that prioritize compounds based on prior knowledge, biology, or chemistry to improve hit rates and efficiency. For B.Pharm students, understanding non-random approaches—such as focused libraries, structure-based and virtual screening, fragment-based discovery, and phenotypic screening—is essential for modern drug discovery and assay development. Key concepts include … Read more
