Researchers at the University of California, Davis, have developed an environmentally friendly one-pot multienzyme (OPME) method for synthesizing sialidase reagents, probes, and inhibitors.
Microbial sialidases (enzymes that catalyze the removal of terminal sialic acid resides) are important anti-viral and anti-bacterial drug targets. Specifically, designing and synthesizing sialidase inhibitors such as 2,3-dehydro-2-deoxy-sialic acids (Sia2ens) and their derivatives have been actively pursued. In addition, 2,7-anhydro-sialic acids and their derivatives can be novel compounds to modulate gut microbiota. However, current methods to synthesize such compounds require the use of toxic chemicals and solvents for multiple protection and deprotection steps. Thus, new methods for preparing Sia2en-based sialidase inhibitors and 2,7-anhydro-sialic acids are needed.
Researchers at the University of California, Davis have developed an enzymatic method for synthesizing Sia2ens and 2,7-anhydro-sialic acids which are sialidase inhibitors, reagents and probes. The OPME method removes the need for multiple protection and deprotection steps. This method has been used to create a library of Sia2ens and 2,7-anhydro-sialic acids from the six-carbon precursors of sialic acids. A streamlined purification process has also been developed. The synthesis and the purification use only methanol and water as solvents. This technology provides efficient enzymatic methods to access useful sialidase inhibitors, potential gut microbiota modulators, and reagents and probes in an environmentally friendly manner.
