Dr. Chris Kevil’s laboratory at LSU Health Shreveport (LSUHS) has discovered that a clinically approved cyclodextrin-based drug called Sugammadex can act as a hydrogen sulfide donor that restores vasoactive hydrogen. This innovation has already gone through initial in vivo testing with promising results.

To take the next leap in development, LSUHS and CarboHyde will start a multiple-staged collaboration project to assess the effects of various cyclodextrins as potential hydrogen sulfide (H2S) donors in methamphetamine-mediated vascular diseases and for various other cardiovascular diseases. Methamphetamine users face a significantly higher risk for cardiovascular disorders, according to a major study published by the Journal of the American Heart Association earlier this year. The Kevil lab has also recently published that chronic methamphetamine use causes cardiovascular dysfunction due to reduced hydrogen sulfide. This poses an additional threat and possible treatment approach for those who use or have already stopped using meth.

LSU Health Shreveport and the Kevil laboratory will focus on comparing the effects of different cyclodextrin derivatives in blood sulfide levels and test the compounds in vitro and in different animal models. CarboHyde’s expertise will be used to select and customize this project’s best-working cyclodextrin derivatives.

“This is exactly the type of research our minds are formed around. We simply admire innovative ideas and out-of-the-box applications of cyclodextrins and other carbohydrates. We keep looking for opportunities to add our knowledge to drive such studies forward. I am sure our collaboration with LSU Health Shreveport and Dr. Kevil will be mutually rewarding and may open novel insights in the application of cyclodextrins in cardiovascular diseases,” said CarboHyde’s CEO József Tóth about this upcoming collaboration.

“Collaboration with carbohydrate expertise at CarboHyde represents a unique opportunity to develop innovative molecules and modalities to treat methamphetamine and other cardiovascular diseases, said Dr. Chris Kevil.


CarboHyde is a private preclinical pharmaceutical start-up company specializing in the development of carbohydrate-based APIs. Our team consists of a small group of seasoned scientists with over 50 years of cumulative experience in the field of carbohydrate chemistry, analysis and pharmaceutical development. The company’s core focus is neurodegenerative diseases, yet we also have other pre-clinical programs in various unmet medical indications. Fully embracing the pharmaceutical development ecosystem, we utilize contract research organizations (CRO) and other companies focusing on CMC and clinical development to make our drug development process efficient. CarboHyde’s management team has extensive experience in medicinal chemistry, marketing, and pharmaceutical development. In addition, CarboHyde is supported by experienced advisers, consultants, and carbohydrate veterans.
