Production of a glucuronide metabolite of praliciguat by microbial biotransformation

Great to see Hypha recognised for producing a glucuronide metabolite of praliciguat (M3) in the paper just out in the journal Pharmacology Research & Perspectives.

There are several pathways involved in the metabolism of praliciguat in rats, including oxidation, reduction, dealkylation, sulfation, glucuronidation and glutathione conjugation. Praliciguat-glucuronide (M3) is the most abundant single metabolite in bile.

Praliciguat-glucuronide

Microbial biotransformation is an efficient and scalable method for producing O-glucuronides and other metabolites of drug candidates. In this client project, nearly 100% of praliciguat was biotransformed to a single O-glucuronide by one of Hypha’s biotransforming microbes to provide a total of 184 mg of purified praliciguat-glucuronide at > 99% purity. The material enabled the structural elucidation of the position of the glucuronide conjugate and was used for determining the identification and circulating concentrations of this metabolite in clinical samples.
