Current Research

Development of New Artificial Enzymes

Drug therapy is among the most successful and reliable treatments for various health issues. However, it is impeded by limitations in chemists’ ability to make the absolutely “correct” drug molecule in a timely and cost-effective manner. The development of artificial enzymes is a new approach in chemistry dedicated to the preparation of molecules with defined 3-D structure (molecular shape), and is of paramount importance to the drug discovery and development because the function of a drug is determined by its overall shape.

Researchers in the Takenaka Lab have developed a new class of artificial enzymes that shape-selectively synthesize molecules with the desired 3-D structure from easily available chemicals. Such technology will provide scientists ready access to precious medicinally active agents, and thus will not only accelerate the drug discovery process, but also lower costs of prescription drugs.


Synthesis of Natural Products

Natural products are the secondary metabolites (small organic molecules) produced in organisms and have long been the source of the great majority of drugs and drug candidates. Indeed, 78% of the antibacterial compounds and 74% of anticancer agents available today are either natural products or their chemical derivatives. The complete chemical synthesis of natural products is the first and key step in such drug discovery endeavors that aim to treat currently incurable diseases.

The researchers in the Takenaka Lab are currently working toward the complete chemical synthesis of the alkaloid Acutumine isolated from the moonseed Sinomenium acutum.
