Medicinal Chemistry 1 Notes PDF Free

Hello in this blog post, I’ve provided an overview as well as download links for notes of Medicinal Chemistry 1(BP402T) according to the PCI syllabus for B Pharm 4th Semester 2023.


The notes in Medicinal Chemistry 1, we have provided two kinds of notes: Handwritten notes and Standard notes.

Medicinal Chemistry 1 notes are designed to provide fundamental information on the chemical structure and therapeutic properties of drugs. The topic focuses on the relationship between the structure and activity of drugs, the significance of physicochemical properties as well as the metabolic process of drugs. The syllabus also stresses an understanding of chemical syntheses for key drugs in each subject…

Friends Medicinal Chemistry 1 is the subject of the 4th semester of the B Pharm course, and as per the syllabus copy of PCI B Pharm 4th semester, there are a total of 5 units in this subject.
