Biosynthesis and Catabolism of Catecholamines | Lecture 17 | Medicinal Chemistry | B.Pharm 4th Sem.

In this lecture, we will study Biosynthesis and Catabolism of Catecholamines, an important and high-weightage topic in Medicinal Chemistry (PCI syllabus, B.Pharm 4th Semester) under Drugs Acting on Autonomic Nervous System (ANS). 📖 Lecture Notes: 👉 https://drive.google.com/file/d/1Sb-m... 📲 WhatsApp Channel (Join for Updates): 👉 https://whatsapp.com/channel/0029Vb7z... 🎥 YouTube Channel (Subscribe): 👉    / @pcipharmaclasses   This is Lecture No. 17, continuing from the previous lecture on Neurotransmitters, where we now move deeper into the formation and breakdown of key neurotransmitters like dopamine, norepinephrine, and epinephrine. Catecholamines are essential neurotransmitters involved in sympathetic nervous system function, and their synthesis and metabolism are very important for understanding drug action, receptor interaction, and pharmacological effects. In this lecture, you will clearly understand: • Stepwise biosynthesis of catecholamines (Tyrosine → Dopamine → Norepinephrine → Epinephrine) • Enzymes involved such as Tyrosine hydroxylase, DOPA decarboxylase, Dopamine β-hydroxylase, PNMT • Catabolism of catecholamines via MAO (Monoamine oxidase) and COMT (Catechol-O-methyl transferase) • Formation of metabolites like VMA (Vanillylmandelic acid) • Clinical significance and drug targeting points • Important exam points and flowcharts for easy revision This lecture is specially designed for: B.Pharmacy 4th Semester students (PCI syllabus) Students preparing for GPAT, NIPER, and competitive pharmacy exams Learners who want strong conceptual clarity in ANS pharmacology and medicinal chemistry This topic is extremely important because it forms the base for understanding: Adrenergic drugs MAO inhibitors and COMT inhibitors Parkinson’s disease drugs Drug metabolism pathways Watch this lecture carefully for exam preparation, viva questions, and concept clarity. #MedicinalChemistry #Catecholamines #BPharmacy #PCI #GPATPreparation #PharmacyStudents #ANS
