How did you decide you wanted to be a scientist?
I was trained as a surgeon in China, and in the early 1980s, came to the United States to further my education. As a physician, I was limited to only being able to help one patient at a time. By contrast, scientists involved in basic research have the ability to address fundamental questions in medicine where any breakthrough or new development can benefit hundreds, if not thousands of patients. I wanted to spend my time more efficiently by helping a larger number of people. Thus, it was with this desire that I chose to enter science and start my research career in Cambridge, UK.
What drew you to pharmacology in particular?
Pharmacology is a subject in which I believed that my clinical experience was best combined with my scientific training. By being able to use all available tools, technologies, and methodologies, one would be able to characterize a substance with biological activities, thereby discovering a drug candidate.
Tell us about a particularly exciting moment in your scientific career so far.
An exciting moment was our serendipitous discovery of a new class of non-peptidic glucagon-like peptide-1 agonists (cyclobutane derivatives, best exemplified by Boc5) with therapeutic effects on diabetic mice. This was considered a disruptive discovery by the scientific community in a difficult research field (i.e. mimicry of the actions of larger peptide for class B G-protein-coupled receptors via a small molecule approach) because our predecessors had all failed in seeking such molecules. This breakthrough took more than 4 years of relentless efforts and unwavering perseverance, with each member of my team playing an indispensablerole. As a result, I was able to take each contribution and bridge them together in a manner that led to this unexpected finding. I am proud that our work has now been reproduced by several laboratories around the world, and our innovation has also been well recognized.
You have been involved in drug discovery through academia, industry, and governmental roles. What lessons do you think the three branches can learn from each other?
I was initially involved in drug discovery in an industrial setting, and later moved back to academia. Drug discovery requires the participation of these three branches. The government institutes the rules, regulations,and laws that govern the discovery and development process. Academia is more inclined towards early-stage discovery, whereas industry has the know-how and economic resources to make a drug candidate enter the market through clinical development. However, the basic principle does not change no matter where drug discovery is conducted, because of the commonalities in this path. The only difference is the emphasis. For example, each branch may approach the same issue from different angles and use entirely different methods to resolve it, but in the end the measure of achievement remains identical. Thus, it is imperative that these three branches cooperate and coordinate with each other in a complementary manner in order to increase research efficiency and enhance the return on investment.
China has seen explosive growth in pharmaceutical development in recent years. What makes China such an attractive place for drug discovery now?
In the past three decades, China has gone through a tremendous transformation, politically, economically,and socially. With modernization of the public infrastructure, the availability of a dazzling talent pool,and enormous investment in research and development (R&D), these three aspects combined have created an unprecedented period in Chinese history in which innovation is not a luxury, but rather a necessity, in order for China to become a true world power beyond its sheer population, geographic size, and booming economy. This is the background behind China’s rise in prominence in drug discovery, whereby almost every  multinational pharmaceutical company has established its own R&D mechanism there. It demonstrates the potential these companies see in China, and their willingness to participate in China’s drive towards innovation. In addition, there is a flourishing (professional and technical) service industry, including several of the largest contract research organizations across the globe, that attracts both domestic and international investors to tap into this historic opportunity.
What do you think the biggest challenge is for drug discovery in China at the moment?
China’s indiginous pharmaceutical industry continues to undergo a process of transformation from imitation to innovation. Although many professional talents are locally situated, they are mainly academics who are inexperienced in the industrial aspects of drug discovery, resulting in amateur attempts and redundancy in efforts. Furthermore, China continues to suffer from a lack of cohesive effort towards a common goal and continues to fall back onto guerilla-like entrepreneurial and self-interested pursuits. Nevertheless, this may change following implementation of the national mega R&D program in drug discovery, which will encourage more joint ventures and cooperation and will emphasize the need to benefit mankind.
What advice would you give to a young person starting a career in pharmacology today?
A pharmacologist has the unique opportunity to be able to help not only the patient but also the doctor. Therefore, it is essential that curiosity and passion for science are combined with pragmatism, whereby knowledge can be appropriately applied to resolve a practical issue through therapeutic intervention with medication.

Abstract Image

Molybdenum- and tungsten-based olefin metathesis catalysts have demonstrated excellent results in the control of cis (Z-) selectivity as well as enantioselectivity. However, their air and moisture sensitivity, which requires the use of a glovebox, has prevented their more widespread use by organic chemists. Now we report on developed, preweighed Mo catalysts formulated in paraffin tablets. 

The significantly improved air stability, high homogeneity, and uniformity of the pellets allow researchers to carry out reactions on the bench avoiding the need of a glovebox.

The two different Mo-based complexes which were packed into tablets are XiMoPac-Mo001 (1) that can be used to achieve endo-selective enyne ring-closing metathesis (RCM) reactions, interalia; and XiMoPac-Mo003 (2) which was reported among the best catalysts to promote Z-selective cross-metathesis. 

For the evaluation of the wax-protected catalysts commonly used, highly reproducible robust model reactions were chosen: homo cross-metathesis (HCM) of functionalized (e.g., methyl 9-decenoate) and unfunctionalized (allylbenzene) terminal olefins, and ring closing metathesis (RCM) of diethyl diallylmalonate. The yields and conversions were comparable with those which can be achieved in glovebox with nonformulated catalysts. 

Exposure to air did not cause any significant reduction in conversion while the product selectivity (targeted product vs homologues derived from double bond isomerization) remained high. In contrast, exposure to air caused a measurable drop in the conversion with the nonprotected catalyst. Furthermore, the formulated catalysts remained unaffected even after 4 h of exposure to air, showing its enhanced air stability. 

In conclusion, these commercially available air-stable Mo-catalyst tablets allow the reactions to be accomplished using ordinary Schlenk techniques, and hence simplify catalyst handling in pilot laboratories and plants.

ABSTRACT: The pharmaceutical manufacturing industry faces the challenging task of operating sustainably with minimal safety, cost and environmental impact. While the ‘D’ part or process development in R&D is a very critical activity toward the scale-up of Active Pharmaceutical Ingredients (APIs) and intermediates, the ‘R’ part (process research) can also profoundly influence the API manufacturing industry; and it can be a deciding factor in the greenness of the process. The concept of Green Chemistry by Design (GCbD) enables one to understand the relationship between process research, sustainability and economics with respect to API. Proactively designing synthetic routes by recognizing criteria such as safety, environmental, legal, economics, control as well as throughput is an important step in the selection of a practical synthetic route. More often than not, a cost effective process is a green process. Existing and emerging scientific tools and technologies when identified and applied appropriately contribute to greener and more economical routes on large scale. Additionally, with the wealth of new reactions that continue to be discovered in the academic world, the field of process research toward organic compounds continues to remain dynamic, thus providing opportunities to develop green synthetic routes.
INTRODUCTION
The pharmaceutical industry has continued to go through major changes since its inception. More drugs than before continue to be discovered, developed and launched, benefiting the patient and thus reducing the burden of disease. While the advantages of this established and yet growing industry are undeniably obvious, the challenges that it continues to face are unique. Sustainable and efficient production of chemicals with the least impact on the environment remains a difficult task, given the various hurdles faced by the industry such as cost-effectiveness, regulatory, legal, robustness, “greenness” and safety. These changing times have stirred the industrial and academic scientific community to work toward developing better reactions and processes. Until recently, the development of green and environmentally friendly processes remained confined mostly to the innovator and generic pharmaceutical companies; while today the growing API business demands the same in pursuit of sustainability, cost-effectiveness and value addition for its customers.
A sustainable process for an intermediate or an API stems from an innovative, well-thought out and planned process R&D work based on the principles of Green Chemistry. The term E (environmental) factor, defined as the kilograms of waste per kilogram of product, was introduced as a measure of the environmental effect of a manufacturing process in various chemical businesses (1). While there are several other measurable terms and concepts in Green Chemistry, the E-factor remains widely used and represents the actual amount of waste produced in a chemical process (2). Compared to the other segments of the industry, the pharmaceutical and fine chemical industry generates significant waste per kilogram of product, mainly due to the complexity of the synthetic processes involved thus leading to higher E-factors. However, with the introduction of...In order to continue reading this article please register to our website – registration is for free and no fees will be applied afterwards to download contents.
