DAY 326/327

Jul 24 & 25

1) All good things must come to an end, so the saying goes. And just like that, my summer research is drawing to a close. It has been an absolute privilege working at the Apjohn Chemistry Research Laboratory, under my Principal Investigator, Dr. Darren Griffith.

2) Less than two months ago, I started work here as a summer research student, under the RCSI Research Summer School programme. My project was entitled, "Novel Bismuth Compounds as Potential Antimicrobial Drugs". We wanted to combine the antimicrobial properties of bismuth with the Fe-binding properties of iron chelators.

3) And here to help me throughout that journey was Mr. Donal Keogan, a final year PhD student. Under their superb tutelage and guidance, my love for chemistry and research as a whole grew. I've a newfound appreciation for the researchers working long shifts in the labs; uncertain if their reactions would turn out successful or not.

4) Most of the time, my day would begin at around 9.00am, where I'd set up an experiment. Sometimes analysis of a product was required, so we'd head over to York House to do mass spectrometry or NMR spectroscopy. Other analytical methods such as X-ray crystallography and elemental analysis had to be sent off to various labs for testing, as we didn't have the required facilities.

5) I'll cherish the growth and progress that I've made throughout my eight week tenure here. I vividly remember being unable to recall any of the reactions that I had done, to learning how to write them on my gloves, and finally being able to draw the structures of the compounds themselves from memory. Thin layer chromatography (RF values), separation using separating funnel (Partition coefficients), vacuum filtration, reflux, mass spec (molecular ion peak) and NMR spectroscopy - these were things whose theory we learnt in A-levels, but now I had the first hand experience of carrying them out in the labs.

6) At the end of the day, research in the labs has provided me with a different perspective on what goes on behind the scenes of every prescribed pill. I understand better how researchers working at the forefront of drug discovery would complement the very doctors who are the first line of contact for patients. And given a chance, I would love nothing better than to pursue this avenue of research to greater depth. Here's keeping my fingers crossed. Thanks for visiting my blog, and have a great day. Cheers!

DAY 284

Jun 12

1) So today there are three important things for me to write about. The first, as you may expect if you've been following my previous updates, is of course on my research. I met up with Dr. Griffith (my Principal Investigator) at around 11am, and it was there that I met Ali, who is also undertaking summer research (albeit under a different project title)

2) Dr. Griffith took us on a tour of all three floors of the Department of Pharmaceutical and Medicinal Chemistry. There, we met the PhD students who would be guiding us with our research. After that , we went over to York House where Dr. Griffith showed us the NMR instrument, used to determine the physical and chemical properties of atoms or the molecules in which they are contained. He also showed us a slew of different apparatus and lab equipment, from HPLCs (High Performance Liquid Chromatography) to THF (tetrahydrofuran). It really was a completely new experience for me.

3) We spent some time outlining exactly my aim of conducting this research, as well as set the list of things I would be required to carry out for this week. For today, he sent some research papers over for me to read, mostly on bismuth and its various potential applications in antimicrobial, antileishmanial, and anticancer therapy. Bismuth is frequently used in quadruple therapy (two antibiotics, a proton-pump inhibitor, and bismuth) for the treatment of helicobacter pylori infections. So the objective of my research is to develop novel bismuth complexes which are effective in these areas of treatment.

4) After the allotted time, I went over to the library. As I've written previously, today is the last day that Mercer Library will be open. After 11pm, it will be shut down for good, and library operations will continue 3rd July at the new academic building. This old building will then be converted for pharmacy students to use. As such, I spent my afternoon there, reading up on the research material that I'd been given to read, as well as taking a nice nap for old time's sake.

5) In the evening, I went for my usual run at St. Stephen's Green. It took a lot of effort to complete 10km (something that I used to do with little effort during my younger years haha), but at least I'm making progress. At least I've the next four and a half months or so to train properly before the SSE Airtricity Dublin Marathon 2017. I for one, cannot wait.

6) Bought my dinner from Subway, before returning home for the rest of the night. That has been my day, and I hope you enjoyed reading about it. Thanks and hope you have a great day. Cheers!

I wonder which "JC2 Student" wrote this? ^^


I've done this before, but which one is mine?? XD


Friendly desk staff


Look forward to meeting everyone again in the new building!!
