PROGETTAZIONE E SVILUPPO DEL FARMACO

Module MODULO 1 CHIMICA FARMACEUTICA

Synopsis: This course will present drug development “Hit to lead selection and validation” as a process involving target selection,  lead discovery and optimization using computer based methods. Along the way the  student  will learn about molecular recognition and  computer aided drug design as applied to the development of new drugs.

Course contents and teaching

Principal aims

To introduce students to molecular modelling techniques as applied to biological systems with particular emphasis on the methods used and their underlying theory. The student should gain a basic understanding of the available computational methods and their theoretical foundations; what time scales and length scales are accessible; what properties can be computed and to what level of accuracy; and what methods are most appropriate for different molecular systems and properties.

Relevant in silico tools along with success stories, possibilities and difficulties.will be also briefly presented.

Subject knowledge and understanding

Have an understanding of the theoretical background and application of computer modelling in medicinal chemistry; Understand the origins of bio-intermolecular interactions, how to model them, and how to relate them to experimental data; Appreciate the advantages and disadvantages (critical ability) of different modelling methodologies .

Principal Learning Outcomes

a)    Ability to implement the above methodologies in practice; b) Ability to analyse a given  problem and select a suitable computational method for studying it; (c) Cognitive Skills: The key challenge for this module is for students to be able to design a molecular modelling experiment, and implement it efficiently on a computer. They will also further understand the statistical analysis and interpretation of the results and the relationship to laboratory experiments.(d) Subject-Specific/Professional Skills: Able to undertake molecular modelling to solve specified problems and critically evaluate data and articles.

Frontal Lessons.

According to  "Regolamento Didattico di Ateneo (R.D.A.) i.e. University Didactic Regulations attendance of  lessons   is mandatory.

Attending the supplementary seminars that are organized  is also strongly recommended.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

Information for students with disabilities and / or SLD: To guarantee equal opportunities and in compliance with the laws in force, interested students can ask for a personal interview in order to plan any compensatory and / or dispensatory measures, based on the teaching objectives and specifications needs. It is also possible to contact the CInAP contact person (Center for Active and Participatory Integration - Services for Disabilities and / or SLD) of the Department of Drug and Health Sciences Prof.ssa Santina Chiechio (santina.chiechio@unict.it).

 TEXTBOOKS AND OTHER RESOURCES

Due to the cutting edge nature of this course and the rapid advances made in the field , a single primary text which adequately covers the content of this  course has not been identified.  Therefore each lecturer will provide the student with additional resources to supplement their lecture material. These resources will take the form of text  books, journal articles (if available links to the electronic form of  these resources will be provided) or web based resources. 

Class Notes; Chemometry booklet;  useful readings suggested from the teacher.

Learning assessment may also be carried out on line, should the conditions require it.

Information for students with disabilities and / or SLD:

To guarantee equal opportunities and in compliance with the laws in force, interested students can ask the staff for an interview in order to plan any compensatory and / or dispensatory measures, based on educational objectives and specific needs.
