Medicinal Chemistry 2

A.Y. 2019/2020
Overall hours
Learning objectives
The course aims at providing the most relevant concepts related to the design, synthesis, physico-chemical and stereo-electronic properties, mechanism of action, therapeutic application and side effects of the drugs belonging to the investigated classes. In particular, lectures will deal with the structure-activity relationships and the approaches applied in medicinal chemistry to optimize the pharmacodynamic profile and the pharmacokinetic properties of drugs. Based on the fundamentals acquired in the course of Medicinal and Toxicological Chemistry 1, in the present course the student should accomplish a good overall background in medicinal chemistry, through the study of drugs acting on the central and peripheral nervous system, the cardiovascular and anti-histamine drugs, the non-steroidal anti-inflammatory agents.
Expected learning outcomes
Expected learning outcomes (nuovo testo da inserire in W4)
Knowledge and understanding. The course aims to ascertaining the student's knowledge of the approaches and methods presented during the lectures, particularly those related to the structural aspects of drugs, their genesis and their therapeutic classification.
Applying knowledge and understanding. During the exam, the student should be able to apply knowledge and understanding, in particular by appropriately discussing the main aspects of the structure/synthesis of the main compounds of a class of drugs, together with their related therapeutic utility.
Making judgements. The student will answer any question with pertinence and criticism, both in the written and oral part of the exam. In their answers, students are frequently requested to motivate their own choices.
Communication. During the exam, the student will demonstrate to explain and develop concepts with clarity, synthesis and language skills. Clarity of presentation and communication skills are part of the overall evaluation.
Lifelong learning skills. The main objective of the course is that to ascertain the strengthening of the student's background in Medicinal Chemistry: the acquired competence will help the student's informed choice (professionalizing courses/thesis lab) towards completing the educational path.

Course syllabus
The course program (10 credits) focuses on the study of biomolecular processes involving neurotransmitters, neuromodulators and second messengers and on the investigation of the structural features (stereo-electronic requirements, topology, topography,  conformational equilibria and acid-base properties) of drugs (ligands) interacting with the main biological targets (receptors,  enzymes, channels). The main medicinal chemistry aspects under study include the structural modifications of biologically active natural compounds, the  modification of molecular portions of "lead compounds" and their impact on the affinity-activity-selectivity-bioavailability profiles, the  discussion of the synthetic strategies of relevant active principles, the new acquirements about the mode of action of drugs and  their impact on therapeutic applications. Based on the above-cited guidelines, the course defines and discusses the following classes of drugs. a) Drugs influencing the parasympathetic neurotransmission (drugs active on nicotinic or muscarinic receptors, cholinesterase  inhibitors) as well as the orthosympathetic neurotransmission (drugs active on alpha- and beta- adrenergic receptors, MAO  inhibitors and COMT inhibitors).  b) Drugs of the central nervous system (anesthetics, anxiolytic and sedative-hypnotic drugs, anticonvulsants, antiparkinsonian  drugs, opioid analgesics, antipsycothic drugs, antidepressants, hallucinogenic drugs and related substances of abuse). c) Drugs of the cardiovascular system (cardioactive glycosides, antianginal drugs, antiarrhythmic drugs, calcium channels blockers,  potassium channels activators, ACE-inhibitors, angiotensin antagonists, diuretics). d) Nonsteroidal anti-inflammatory drugs. e) Antihistaminic agents, anti-allergic and anti-ulcer drugs.

Assessment methods and Criteria
The students attending the whole course have the opportunity, subject to checking their presence to the lessons, to take "two  written midterm exams" (about 2.5 h each). These exams, which are scheduled each academic year on February and July, focus on  the first and second semester program, respectively. They consist of open-ended questions (usually four for each exam), including,  for a given drug, a comment on its structure (that the students will find in the text or should draw) with the main structure-activity  relationships. Then, a discussion on the mechanism of action, the therapeutic class and side effects, the physicochemical properties  and the synthetic approaches. The overall evaluation takes into account the student's ability to organize answers to all questions,  the quality and clarity of presentation and the language used. To pass the exam, the student should reach a sufficient evaluation in  each of the two tests: the final mark is expressed out of thirty (from 18/30 to 30/30 cum laude), and is the grade point average of  the two marks. No oral exams are planned for this exam modality. As in the case of standard exam sessions, mark registration of the exam is subject to passing exams of both Medicinal and  toxicological chemistry 1 and Organic chemistry 2. The "standard exam sessions" consist of a written exam (about 2.5 h) on the entire program, with four open-ended questions as  specified above. To pass the written exam, at least three out of four of the student's answers must be sufficient. Students with a  positive evaluation will take the oral part of the exam, during which, in addition to the discussion on the answers given in their  written exam, they will answer to two/three further questions on other topics of the program. The final mark is expressed out of  thirty (see above), and the evaluation of the written exam has a determinant role. The results on the written exam evaluation are  communicated to the students within two weeks, concurrently with the oral exam. The students failing written exams must sign up  for the next exam session. Written exams may be taken in consecutive sessions without any restrictions. Exam sessions, at least six  per year, are in accordance with the indications from the Faculty of Pharmacy.

Assessment methods and Criteria
The students attending the whole course have the opportunity, subject to checking their presence to the lessons, to take "two written midterm exams" (about 2.5 h each). These exams, which are scheduled each academic year on February and July, focus on the first and second semester program, respectively. They consist of open-ended questions (usually four for each exam), including, for a given drug, a comment on its structure (that the students will find in the text or should draw) with the main structure-activity relationships. Then, a discussion on the mechanism of action, the therapeutic class and side effects, the physicochemical properties and the synthetic approaches. The overall evaluation takes into account the student's ability to organize answers to all questions, the quality and clarity of presentation and the language used. To pass the exam, the student should reach a sufficient evaluation in each of the two tests: the final mark is expressed out of thirty (from 18/30 to 30/30 cum laude), and is the grade point average of the two marks. No oral exams are planned for this exam modality.
As in the case of standard exam sessions, mark registration of the exam is subject to passing exams of both Medicinal and toxicological chemistry 1 and Organic chemistry 2.
The "standard exam sessions" consist of a written exam (about 2.5 h) on the entire program, with four open-ended questions as specified above. To pass the written exam, at least three out of four of the student's answers must be sufficient. Students with a positive evaluation will take the oral part of the exam, during which, in addition to the discussion on the answers given in their written exam, they will answer to two/three further questions on other topics of the program. The final mark is expressed out of thirty (see above), and the evaluation of the written exam has a determinant role. The results on the written exam evaluation are communicated to the students within two weeks, concurrently with the oral exam. The students failing written exams must sign up for the next exam session. Written exams may be taken in consecutive sessions without any restrictions. Exam sessions, at least six per year, are in accordance with the indications from the Faculty of Pharmacy.
