Selected Examples of Natural Products Synthesized by Our Group
Since time immemorial, our ancestors have been using a wide range of natural products to cure various diseases. However, several of these natural products are highly difficult to obtain and reproduce in the laboratory. Therefore, the research in natural product synthesis, both total and partial synthesis, is a significant field of investigation. Considered by many as a leading field in organic synthesis, natural product synthesis represents the power of chemical synthesis at any given time by attempting to push its frontiers into higher molecular complexity, diversity, and efficiency.
As an avenue for the application of our developed synthetic approaches, our laboratory is also highly interested in developing new drugs or exploring more efficient and step-economic routes to access biologicdenyy active compounds and natural products. To evaluate the potential of our synthesized compounds, we perform several tests to assess biological properties which include, but not limited to, anti-bacterial, anti-biofilm, antioxidant, and anticancer activity.
