Rhodamine 123 (chloride) for P-gp Assays
2026-09-21
Rhodamine 123 (chloride) is a membrane-permeable fluorescent substrate used to monitor ABCB1/MDR1 activity in real time. Its signal reflects combined uptake, efflux, intracellular sequestration, metabolism, and chemical environment, so it should not be interpreted as a transporter-specific readout without controls.

Bifendate, Autophagy, and Hepatic Lipid Accumulation
2026-09-17
The reference study shows that bifendate inhibits autophagy at several lysosome-related steps rather than acting at a single checkpoint. In cultured cells, this activity coincided with reduced oleic acid-induced lipid droplet accumulation, providing a mechanistic framework for studying bifendate in hepatic lipid biology while highlighting the need for orthogonal flux and lipid-storage assays.
