Asymmetric Synthesis of Drugs and Natural Products …

Working with a natural product compound has always been a challenge. From extraction, purification, isolation, structure characterization and chemical synthesis, natural product research has faced many pitfalls and hurdles that can be overcome by an intelligent use of analytical technology. This conference will focus on key areas of natural product research.

Synthesis of Alocasin A - Journal of Natural Products …

This review is an updated and expanded version of a paper that was published in this journal in 1997. The time frame has been extended in both directions to include the 22 years from 1981 to 2002, and a new secondary subdivision related to the natural product source but applied to formally synthetic compounds has been introduced, using the concept of a “natural product mimic” or “NM” to join the original primary divisions. From the data presented, the utility of natural products as sources of novel structures, but not necessarily the final drug entity, is still alive and well. Thus, in the area of cancer, the percentage of small molecule, new chemical entities that are nonsynthetic has remained at 62% averaged over the whole time frame. In other areas, the influence of natural product structures is quite marked, particularly in the antihypertensive area, where of the 74 formally synthetic drugs, 48 can be traced to natural product structures/mimics. Similarly, with the 10 antimigraine drugs, seven are based on the serotonin molecule or derivatives thereof. Finally, although combinatorial techniques have succeeded as methods of optimizing structures and have, in fact, been used in the optimization of a number of recently approved agents, we have not been able to identify a combinatorial compound approved as a drug in this time frame.

Chemoenzymatic Synthesis of Natural Products and …

Kicking off the afternoon session on biosynthetic pathways of natural products was a talk from David Sherman (University of Michigan) on a new class of indole alkaloid cyclases from cyanobacteria. Paul Jensen (Univ. of California, San Diego) gave an excellent talk about understanding certain gene clusters and what their function may be in biosynthetic pathways of a marine natural product. A diversion followed with a graduate student talk from Ross McLennan (Univ. of St. Andrews) on his approach to the synthesis of pyronnazol A. The afternoon highlight was the final speaker of the day, Paul Wender (Stanford Univ.) sharing many marvelous synthetic projects, inspired by a natural product, on therapeutic agents to treat HIV, Alzheimer’s disease and cancer.

Herein we describe an iterative application of asymmetric copper catalysis towards the synthesis of six distinct oligomeric polypyrroloindoline natural products: hodgkinsine, hodgkinsine B, idiospermuline, quadrigemine H and isopsychotridine B and C.

total synthesis of complex natural products.

The opening talk was given by Bill Gerwick (Univ. of California, San Diego) where he detailed an NMR tool, Small Molecule Accurate Recognition Technology (SMART), which helps identify and map structural classes based on molecular fragments of natural product molecules from marine sources. This was followed by a macrolide synthesis lecture from Patrick Harran (Univ. of California, Los Angeles that concluded a short morning session.

The third in the series of natural product conferences was convened in beautiful Cancun, Mexico. Extending on the theme of the science of natural product research and the technology that drives the results from version #2, a wonderful group of scientists comprised of synthetic chemist, marine natural product chemists and young investigators in the field presented stirring science of all facets of natural product research. The hardware and technology that drives natural product research was evident in all presentations.

Natural product synthesis plays a key role in our research programmes. Over the years we have assembled over 140 complex and architecturally challenging structures. These efforts lead to the discovery of many new processes which find wider application in chemical synthesis. This area is a superb and creative training ground for anyone interested in learning the art of organic synthesis.

Yoshio Ando was born in 1979 in Kitakyushu, Japan, and received his B.S. degree in 2002 and Ph.D. degree in 2007 guided by Prof. Takashi Takahashi in the Department of Applied Chemistry at Tokyo Institute of Technology, where he worked on the development of bioimaging probes based on the oligosaccharide skeleton. From 2007 to 2008 he worked as a postdoctoral research associate with Prof. Dale L. Boger in the Department of Chemistry at The Scripps Research Institute. In 2008, he was appointed as Assistant Professor in the Department of Chemistry at Tokyo Institute of Technology in the research group of Prof. Keisuke Suzuki. He received the Mitsui Chemicals Award in Synthetic Organic Chemistry (Japan) in 2013 and Asian Core Program/Advanced Research Network Lectureship Award (China) in 2015. His research interests include the development of new synthetic methodology and total synthesis of complex natural products.

The exquisite diversity, reactivity and biological function of these molecules constantly challenges the very frontiers of our science in terms of assembly and reactivity. The target-orientated approach imposes a discipline which is hard to match by other areas of chemistry. Natural product synthesis has a rich history of discovery and innovation which continues today; often it provides the basis to ask new questions and solve previously considered impossible processes, thereby leading to step-change advances and transformation of the subject.
