Dr. Guo, you are an experienced medicinal chemist, a veteran in the field. Can you tell us more about your background before joining WuXi?

Tao: I have known Dr. Ge Li for many years from our time together at Columbia University and Pharmacopeia. I greatly admire his courage and vision in founding WuXi. At Pharmacopeia, I worked with WuXi’s FTE teams for a number of programs that I led and was extremely impressed by the high quality work and the impact that WuXi had on my projects. I ultimately decided to join WuXi in 2008 because I was inspired by Dr. Li’s vision in transforming drug discovery through an open access platform. I am excited to be here and to contribute to WuXi’s growth.

After years of working in biotech in the U.S., you are now working with our IDSU teams in China. How is working in China different from working in the U.S.?

Tao: The teams in China are young and energetic. The average age of WuXi employees in China is 29. We offer numerous training programs at WuXi for young scientists. For young chemists, we have a range of chemistry and management training including synthetic chemistry, medicinal chemistry, and program management. Coming to work every day, I feel the strong enthusiasm and energy from our young scientists. I am very proud to see the rapid growth of our young employees and their impactful contributions to our partners’ programs.

What sort of results and impact have you seen with our IDSU teams in China?

Tao: IDSU teams in China have demonstrated strong capabilities in synthetic and medicinal chemistry. Over the last year, the teams have delivered over 70,000 compounds for over 100 clients from pharma, biotech, and non-profit organizations. The teams have discovered over 25 preclinical candidate compounds, including compounds that have received breakthrough therapy designations from FDA, serving as examples of our vision, “invented in China, for the world”. The teams’ efforts have made positive contributions to the successful IPO/partnering of 5 biotech companies.

IDSU has achieved a lot in the past decade. What do you see as future directions for IDSU?

Tao: We are building IDSU to be the best solutions provider in synthetic and medicinal chemistry to clients around the globe. As IDSU has become the largest capability and technology platform for discovery chemistry service in pharmaceutical and biotech industry, the insights gained from our many years of deep experience help us develop a range of tailored solutions to best meet the different needs of our diverse customers. We also continue to strengthen our technology capabilities to keep our leadership position in discovery chemistry.

Thank you for taking the time to talk with us. To finish, would you like to share an inspiring experience or event in the field that has impacted you?

Tao: The Nobel Prize Committee awarding William C. Campbell, Satoshi Omura, and Youyou Tu with the 2015 Nobel Prizes in Physiology and Medicine for their discovery of ivermectin and (+)-artminsinin was very inspirational to me this year. Ivermectin and Artminsin are used to cure diseases caused by parasitic roundworms and malaria, respectively. William C. Campbell was a chemist at Merck when he made his discovery of ivermectin; his recognition was encouraging to all in the drug discovery industry. Youyou Tu’s recognition was especially impactful for all Chinese scientists and chemists here in WuXi, as she was the first Chinese scientist to earn the Nobel Prize.

Interview with John Wai, PhD

Meet Dr. John Wai, PhD  Vice President of Medicinal Chemistry


Prior to WuXi, John spent over 20 years at Merck Research Laboratories, contributing to the discovery efforts of many programs, from target validation & lead identification to lead optimization & early development. This includes HIV-1 non-nucleoside reverse transcriptase inhibitors, ras-farnesyl protein transferase inhibitors, fibrinogen receptor antagonists, HIV integrase strand transfer inhibitors, HIV RNase H inhibitors, gamma secretase inhibitors, etc.  John received the Distinguished Scientific Award from the inaugural Merck West Point Basic Research Reward and Recognition Forum for his work on HIV integrase inhibitors, and recently, John received the “Heroes of Chemistry” Award from the American Chemical Society (September 2013) for his contribution to the discovery and development of Isentress, the first HIV integrase inhibitors approved for treatment of AIDS (2007).  This week we sat down with John to discuss his career and thoughts on the industry.

How did you get started as a medicinal chemist?

John: After my post-doc I joined the Merck unit at West Point. It was a great, varied introduction to life as medicinal chemist. My role involved everything from target validation through to early development of HIV-1 non-nucleoside reverse transcriptase inhibitors, ras-farnesyl protein transferase inhibitors, fibrinogen receptor antagonists and other targets.

What attracted you to working at WuXi?

John: The commitment to chemistry. Having spent the formative years of my career at Merck I’m used to working in a science-driven culture. This is how I like to work and fortunately I found the same culture at WuXi. Once I saw WuXi shared my belief in the importance of cutting-edge medicinal chemistry it was an easy decision to join the company.

What is the proudest achievement of your career so far?

John: It was an honor to be part of the Merck team that developed the first integrase inhibitor approved for use in HIV infected patients. Many thought the target was undruggable, but after more than a decade of work we showed it was! Being named the 2013 ACS Heroes of Chemistry was a nice coda to a very rewarding project.

What does the future hold for medicinal chemistry?

John: It’s an exciting time. The industry is pursuing challenging therapeutic targets, but, as we showed with the integrase inhibitor, hard work and expertise can make what seems impossible today, achievable. WuXi’s investment in new technologies and processes is really helping in this regard.
