Professor Ronald Raines

Professor Ron Raines works with Sigma-Aldrich on the development of reagents and tools for chemical biology such as the traceless Staudinger ligation reagent (670359). DTBA (774405), a superior biological reducing reagent to DTT, is another technology to come out of the Raines lab.  Other exciting research has led to an RNA-cleaving enzyme that is in a multi-site human clinical trial as an anti-cancer agent, revealed that an unappreciated force—the n-to-pi* interaction—stabilizes all proteins, created hyperstable and human-scale synthetic collagens, and established chemical processes to synthesize proteins and convert crude biomass into useful fuels and chemicals.

Dithiothreitol (DTT) is the standard reagent for reducing disulfide bonds between and within biological molecules. At neutral pH, however, >99% of DTT thiol groups are protonated and thus unreactive. Herein, we report on (2S)-2-amino-1,4-dimercaptobutane (dithiobutylamine or DTBA), a dithiol that can be synthesized from l-aspart...Read More

The trimethyl lock is an o-hydroxydihydrocinnamic acid derivative in which unfavorable steric interactions between three pendant methyl groups encourage lactonization to form a hydrocoumarin. This reaction is extremely rapid, even when the electrophile is an amide and the leaving group is an amino group of a small-molecule drug,...Read More

The engineering of proteins can illuminate their biological function and improve their performance in a variety of applications. Within the past decade, methods have been developed that facilitate the ability of chemists to manipulate proteins in a controlled manner. Here, we present the traceless Staudinger ligation as a strate...Read More
