Learning Outcomes

By the end of this course, students will be able to:
  1. Describe how antimicrobial peptides function understand the basic principles of peptide synthesis and be able to write the structure of a Peptide from constituent amino acids. (Capability 1, 2 and 3)
  2. Apply he principles of molecular recognition and intermolecular bonding interactions, to the development of enzyme inhibitors and receptor agonists and antagonists as drugs. (Capability 1, 2 and 3)
  3. Describe the mechanism of action and structure-activity-relationship of classic molecules like Penicillin, Morphine, Cisplatin, antigene and antisense oligonucleotides etc. (Capability 1, 2, 3, 4 and 6)
  4. Apply the "profit: need : threat" rationale for the drug discovery process using examples, describe How Lipinski’s 'rule of five' to determine 'drug-like molecules’ and Explain why halogens are often incorporated into pharmaceuticals, using examples. (Capability 1, 2 and 3)
  5. Apply he principles of combinatorial chemistry solid-phase organic synthesis (SPOS) in the drug discovery process to generating new drug leads. (Capability 1, 2 and 3)
  6. Apply the principles and ideas are behind QSAR studies, explain the concept of prodrugs, explain the importance of the molecular shape and flexibility (stereochemistry principles) and how the physicochemical properties of the drugs are important and can be incorporated in drug design. (Capability 1, 2, 3 and 4)
  7. Evaluate the influence of tissue pH, drug pKa and logP to the ability of the drug to cross membranes and enter cells as well as use the Henderson-Hasselbalch equation to determine the percentage of drug ionisation (known pKa) in tissue at a particular pH and understand the effect that pH has on solubility and hence therapeutic effectiveness (Capability 1, 2, 3 and 4)
  8. Describe the structural features of surfactants and liposomes that make them useful as drug delivery agents in order to overcome issues of drug solubility and metabolic stability and to improve drug targeting. (Capability 1, 2 and 3)
  9. Identify and explain metabolic reactions into phase I and II, relate these to the functional group or structure may undergo and predict the resultant metabolite; identify the types of enzymes and co-enzymes needed for the metabolic reaction and describe some examples where knowledge of the metabolic fate of a lead compound has been used to design a more effective drug. (Capability 1, 2 and 3)
  10. Describe he general mechanisms utilised by bacteria in drug resistance and give an example of an antibiotic that succumbs to each mechanism (Capability 1, 2, 3, 4 and 6)

Workload Expectations

This course is a standard [15] point course and students are expected to spend 10 hours per week involved in each 15 point course that they are enrolled in.

For this course, you can expect [30] hours of lectures, a [6] hour tutorial, [60] hours of reading and thinking about the content and [40] hours of work on assignments and/or test preparation.

Digital Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

Copyright

The content and delivery of content in this course are protected by copyright. Material belonging to others may have been used in this course and copied by and solely for the educational purposes of the University under license.

You may copy the course content for the purposes of private study or research, but you may not upload onto any third party site, make a further copy or sell, alter or further reproduce or distribute any part of the course content to another person.

Academic Integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed against online source material using computerised detection mechanisms.

Inclusive Learning

All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.

Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website at http://disability.auckland.ac.nz

Special Circumstances

If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.

If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page: https://www.auckland.ac.nz/en/students/academic-information/exams-and-final-results/during-exams/aegrotat-and-compassionate-consideration.html.

This should be done as soon as possible and no later than seven days after the affected test or exam date.

Student Feedback

During the course Class Representatives in each class can take feedback to the staff responsible for the course and staff-student consultative committees.

At the end of the course students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback.

Your feedback helps to improve the course and its delivery for all students.

Student Charter and Responsibilities

The Student Charter assumes and acknowledges that students are active participants in the learning process and that they have responsibilities to the institution and the international community of scholars. The University expects that students will act at all times in a way that demonstrates respect for the rights of other students and staff so that the learning environment is both safe and productive.
