Mike Greig | omg OMx Podcast | Ep. 9
What are some vital classes you’ve got discovered in your profession, and are there any vital people who have helped you alongside the best way?
Once I began my profession in biotechnology, my boss was Wealthy Griffey. He ran our group like a Ph.D. program. Earlier than I left Isis Prescription drugs, I had virtually 20 publications protecting every little thing from gas-phase chemistry of nucleotides to structural evaluation of native mass spec.
Being in biotech within the Nineties, you needed to study many various issues. You additionally needed to contribute to basic science to reveal to Isis that these totally different biotech firms deserved funding. It was a good time to be in biotech. Even now, in a small biotech firm, you could study every little thing to contribute meaningfully and make the corporate profitable.
Whereas at Isis Prescription drugs, I had the chance to be a visiting scientist with Marshall’s group, which took place at an ASMS. At my first ASMS, I met Jared Rader and Chris Hendrickson. Chris Hendrickson is now the director of the MagLab.
I met them on an elevator at ASMS. We received speaking and have become good mates. About three ASMSs later, we mentioned mass spec and our respective fields. That is once I went to their lab and began working with them as a visiting scientist.
Is there a science “OMG” second, even when it isn’t mass spec associated, that made you’re keen on the sector of chemistry?
I went to Buffalo Grove Excessive Faculty within the northwest suburbs of Chicago. I took AP chemistry with Dr. Bowles. He was an incredible individual — tremendous energetic and made the category very gratifying, which is sort of outstanding for an AP chemistry course.
A few weeks earlier than the Christmas break one yr, we did a saccharides experiment. We had been mixing all these compounds and made two ropes, a crimson and a white. We twisted them up and he informed us to place a bend in them. All people within the class out of the blue realized that we had simply made sweet canes. That is how he turned science into sweet for us. It confirmed us that science might embody every kind of issues, and could be enjoyable and engaging.
What developments have you ever noticed within the fields that you’ve been in, whether or not in pharma or another sectors?
The developments in drug discovery all through my profession have been wonderful in the best way approaches, throughput, and pace have advanced. What a single scientist can contribute now could be outstanding, primarily because of expertise and the web.
The good factor about working with Bruker now could be that I get to go to folks in different pharma and biotech labs and discuss concerning the science they’re doing intimately. What all people is doing in these labs is simply phenomenal at a person degree.
When it comes to mass spec, the developments within the usability and robustness of devices have been wonderful to witness. Once I first began, I used a single quad instrument with fusion pumps. I needed to rebuild that instrument each different day to maintain it working. Though this was nice as a result of I discovered quite a bit about mass spec by constructing, rebuilding, and changing elements, I’d not suggest it for a high-throughput lab.
Now, the devices, software program, {hardware}—every little thing about mass spec is extra usable. Twenty years in the past, you’d by no means see devices in mass specs and biology labs. Now, they’re in every single place.

Are you able to inform us extra concerning the evolution strategy of a drug?
Most locations begin with a illness or therapeutic space, and you then determine what your goal goes to be. There are numerous publications, akin to Time Journal, that say, “Oh, most cancers is cured. We discovered the subsequent goal,”. Whether or not it’s Time Journal, Analytical Chemistry, or Science, it’s a fixed bombardment of recent targets for oncology, coronary heart illness, or different therapeutic areas.
I primarily labored in oncology throughout my final 10 years at Pfizer, so I’m most acquainted with that area. However you continuously see all these targets which have the potential to treatment totally different sorts of breast most cancers, in addition to different sorts of most cancers. Subsequently, the very first thing we do in pharma is that we validate these targets.
As soon as a goal has been validated by a number of organic, analytical, and different strategies, we proceed with a high-throughput screening marketing campaign. Whereas this high-throughput screening marketing campaign goes on, there’s additionally quite a lot of work in biology, which incorporates analytical chemistry to determine the mechanism of motion.
If the mechanism of motion could be outlined, the possibilities of success in scientific trials enhance dramatically. The following stage entails progressing down the pipeline, getting a lead compound, and searching for biomarkers. Having good biomarkers additionally will increase the prospect of scientific success considerably.
As you progress downstream, you get into the preclinical or pre-human research. Then you definitely progress to the human research part one trial. This part usually exams if the drug is tolerable to people. You then transfer to part two and part three the place the efficacy is evaluated and at last, the drug is able to hit the market.
What are some vital boundaries to the marketability of mass spectrometry within the pharma or biopharma business?
Mass spec is already extremely marketable to the pharma business. Nearly each single pharma lab has a mass-spec instrument in operation. To reinforce marketability, the hot button is to enhance the benefit of use and software program.
There are numerous core mass spec labs the place the folks within the lab are gearheads who wish to do every little thing with the instrument and do quite a lot of exploration. Alternatively, there are additionally recombinant protein labs the place the main target is on making proteins for venture groups, and so they merely wish to look at and acquire an correct mass of the intact protein.
These labs need the mass spec to be only a walkup instrument. There are already many walkup devices for chemistry and biology. So, ease of use is already there. Now, the one query is whether or not we are able to make these complicated experiments simpler to do and reproducible.
Commonest sorts of experiments are already established. We are actually pushing into superior realms akin to top-down sequencing out of biofluids. Because the complexity of the samples will increase, the necessity for added improvements will even enhance.
