In Vitro FERb 033 (0-100 μM) shows specificity on full-length of estrogen receptor (ESR) in transactivation[2]. FERb 033 (10 nM, 2 h) treatment mildly decreases Ca2+ response in airway smooth muscle (ASM) cells[3]. Cell Viability Assay[2] Cell Line: HEK293 cells Concentration: 0-100 μM Incubation Time: Result: Induced transcriptional activity via full-length receptor on ERE with EC50 values of 0.253 and 0.053 μM for ESR1 and ESR2, respectively. Cell Viability Assay[3] Cell Line: ASM cells Concentration: 10 nM Incubation Time: 2 hours Result: Tended to decrease histamine-elicited Ca2+ response in nonasthmatic human ASM cells but not significantly compared to the control.
