Messenger RNA, or mRNA, represents a relatively new class of therapeutics with the potential to prevent and treat a wide range of diseases. A well-known success story is of the mRNA vaccines that controlled the COVID-19 pandemic, which has fueled enthusiasm for the field. But biotechs are also developing mRNA candidates for several other infectious diseases, including malaria, tuberculosis and HIV, as well for cancer, autoimmune and allergic diseases. However, delivering nucleic acid therapeutics can be challenging, since mRNA cannot get into cells on its own.

As its name suggests, Superluminal Medicines Inc. is aiming for speed. The startup, which closed a $33 million seed round led by RA Capital Management, is combining a biology-focused approach with a generative AI platform it says has the potential to create candidate-ready compounds in a matter of months, with its initial sights set on G protein-coupled receptor targets.

A new drug that inhibits the glutamate carboxypeptidase II (GCPII) enzyme could be used to treat inflammatory bowel disease (IBD), according to a new study in mice and human organoids. After decades of research trying to design GCPII inhibitors against neurological disorders, the new compound could be effective for another use.
