(S)-MK-26
(S)-MK-26 is a chemical compound. While the exact chemical structure and specific applications are proprietary information, the "MK-" prefix in its designation suggests it was, or is, a research compound developed by Merck & Co., Inc. Merck uses the "MK-" prefix to internally identify compounds in their research and development pipeline. The "(S)-" prefix indicates the stereochemical configuration of the molecule, specifically the S-enantiomer. This implies that (S)-MK-26 is a chiral molecule existing in two enantiomeric forms (S and R), and that this particular form has been isolated or synthesized. Further information regarding its specific properties, therapeutic area, or status in development is not publicly available. Given the lack of publicly accessible information, it is likely a compound in early stages of research, abandoned during development, or used solely for internal research purposes.
