Phlorhizin
Phlorhizin is a non-transportable glucose analog that inhibits the sodium-glucose cotransporter 1 (SGLT1) and aldohexose transporter (GLUT2), leading to reduced intestinal absorption and increased renal excretion of glucose, which is used in research to study glucose transport and diabetes-related processes.

Mannitol is also commonly used as a research tool in cell biological studies, usually to control osmolarity.
