Prerequisites:

Lo studio richiede una buona conoscenza della Chimica Organica e dei concetti fondamentali di Biochimica.
Al fine di comprendere e saper applicare la maggior parte delle tematiche descritte nell'insegnamento è necessario aver sostenuto con successo l'esame di Chimica Organica e Biochimica.
Gli argomenti trattati nell'insegnamento richiedono una buona conoscenza delle strutture proteiche, delle principali tipologie di interazione inter ed intramolecolari, i principali parametri chimico-fisici che caratterizzano un farmaco. La buona conoscenza di queste tematiche è un prerequisito importante per lo studente che voglia seguire il corso con profitto.
Esami propedeutici: Chimica organica
The study requires a good knowledge of Organic Chemistry and the fundamental concepts of Biochemistry.
In order to understand and be able to apply most of the topics described in the course it is necessary to have successfully passed the exam of Organic Chemistry and Biochemistry.

The topics covered in the course require a good knowledge of protein structures, the main types of inter and intramolecular interaction, the main chemical-physical parameters that characterize a drug. Good knowledge of these topics is an important prerequisite for the student who wants to follow the course profitably.
Introductory examinations: Organic chemistry

Objectives

The course is aimed at acquiring knowledge and understanding the classification, nomenclature, structural properties, reactivity of the main simple and condensed heterocyclic compounds of pharmaceutical interest; provide a general knowledge of synthetic strategies and functionalization of heterocyclic systems, with particular attention to intermediates involved in reactions.

Extended Syllabus

Generalità: Definizione, caratteristiche chimiche, diffusione in natura, utilizzo pratico.
Introduzione ai composti eterociclici: Classificazione e nomenclatura italiana ed inglese dei principali composti eterociclici e policiclici. Sistema Hantzsch-Widman, nomi d'uso, nomenclatura dei tautomeri; sistemi eterociclici condensati, nomenclatura sistematica alternativa, composti eterociclici spiranici. Basicità dei sistemi eterociclici azotati.
Utilizzo del programma ChemDraw (online e offline) per assegnare e controllare la nomenclatura.
Parte specifica: La trattazione di ogni anello eterociclico consiste in ciascuna delle parti che seguono: struttura e proprietà fisiche; proprietà chimiche e metodi di sintesi; derivati principali, prodotti naturali, farmaci correlati, intermedi industriali; uso come reagenti, building-blocks o ausiliari in sintesi.
- Reattività dei sistemi eterociclici. Reattività dei sistemi eteroaromatici: comportamento di fronte agli elettrofili, reazioni di sostituzione nucleofila, comportamento di fronte ai riducenti e agli ossidanti. Idrossiderivati di sistemi eteroaromatici: tautomeria cheto-enolica, reattività nucleofila. Amminoderivati di sistemi eteroaromatici: basicità, reazione di diazotazione.
- Classi farmaceutiche di derivati eterociclici: Benzodiazepine, barbiturici, chinoloni, piridine, piperidine, pirimidine, fenotiazine, cumarine.
General section: Definition, chemical characteristics, diffusion in nature, practical use.
Introduction to heterocyclic compounds: Italian and English classification and nomenclature of the main heterocyclic and polycyclic compounds. Hantzsch-Widman system, use of names, nomenclature of tautomers; condensed heterocyclic systems, alternative systematic nomenclature, spiranic heterocyclic compounds. Basicity of nitrogenous heterocyclic systems. Using the ChemDraw program (online and offline) to assign and control nomenclature.
Special part: The treatment of each heterocyclic ring consists of each of the following parts: structure and physical properties; chemical properties and methods of synthesis; main derivatives, natural products, related drugs, industrial intermediates; use as reagents, building-blocks or auxiliaries in synthesis.
- Reactivity of heterocyclic systems. Reactivity of heteroaromatic systems: behavior in front of electrophiles, nucleophilic substitution reactions, behavior in the face of reducing agents and oxidants. Hydroxyderivatives of heteroaromatic systems: keto-enolic tautomerism, nucleophilic reactivity. Amino derivatives of heteroaromatic systems: basicity, nitrogen reaction.
- Pharmaceutical classes of heterocyclic derivatives: Benzodiazepines, barbiturates, quinolones, pyridines, piperidines, pyrimidines, phenothiazines, coumarins.

Teaching Methods

Lezioni frontali con l’ausilio di supporti multimediali. Durante il corso, l'insegnante verifica la capacità di conoscenza degli studenti riguardo agli argomenti proposti attraverso test di autovalutazione da svolgere in autonomia o in un confronto di gruppo. Ciò non ha alcun impatto sulla valutazione finale dello studente ma ha lo scopo di monitorare e accompagnare lo studente ad uno studio metodico e continuativo durante tutto il corso.

Lectures with the help of multimedia supports. During the course, the teacher verifies the students' ability to know the proposed topics through self-assessment tests to be carried out independently or in a group comparison. This has no impact on the final evaluation of the student but aims to monitor and accompany the student to a methodical and continuous study throughout the course.

Evaluation methods

Verification of learning:

The final evaluation consists of an oral exam. The type of talk aims to cover the entire program carried out and verify the level of learning achieved, the ability to correctly apply the knowledge acquired, the ability to develop solutions in autonomous judgment.

The exam aims to verify the level of learning of the student and the ability to argue on topics related to the entire program in an appropriate manner. The student must demonstrate their knowledge of the chemical structures and chemical properties of drugs, the pharmacological target and the pathology for which the drugs are used as well as the summaries proposed during the course.
