生物活性 | AT-1002 TFA, a 6-mer synthetic peptide[1], is a tightjunctionregulator and absorption enhancer[2]. |
体外研究 (In Vitro) | AT-1002, a 6-mer synthetic peptide, belongs to an emerging novel class of compounds that reversibly increase paracellular transport of molecules across the epithelial barrier. AT-1002 can undergo Cys-Cys dimerization[1]. Undifferentiated Caco-2 cells are treated with AT-1002 (0 to 5 mg/mL, 3 or 24 hours) and viability is assessed by measuring cellular ATP content. Treatment with AT-1002 for up to 3 h does not affect cell viability at any concentration. In particular, the viability of Caco-2 cells is not affected by 5 mg/mL AT-1002. AT-1002 reduces cell viability after 24 h at concentrations of 2.5 mg/mL and higher. However, the cells remain viable after 24 h if the cells are washed after exposure to AT-1002 for 3 h indicating that AT-1002 does not irreversibly damage cells[2].
Cell Viability Assay[2] Cell Line: | Caco-2 cells | Concentration: | 0 to 5 mg/mL | Incubation Time: | 3 or 24 hours | Result: | Treatment for up to 3 h did not affect cell viability at any concentration. Reduced cell viability after 24 h at concentrations of 2.5 mg/mL and higher. |
