UK-5099 (Synonyms: PF-1005023;UK5099;UK 5099;PF1005023;PF 1005023)

Cell experiment:

The 832/13 cell line is used for experiments. Cell viability is measured using CellTiter Blue. The assay is based on cellular reduction of resazurin to resorufin. Appearance of resorufin is monitored by fluorescence emission at 585 nm using a Spectramax M5 microplate reader with excitation at 555 nm. For UK5099-treated cells, cells are allowed to recover for 1 h before measuring cell viability. Data are expressed as -fold relative to no treatment or siCtrl[4].

Animal experiment:

C57BLK mice are fasted for 16 h prior to glucose challenge. UK5099 (32 μmol/kg of body weight) or DMSO in PBS is injected into the intraperitoneal cavity 30 min before injecting glucose (1.5 mg of glucose/g of body weight). Blood glucose levels are measured at 0, 10, 20, 30, 60, and 120 min after glucose injection[4].
