Description: AT-1002, a 6-mer synthetic peptide[1], is a tight junction regulator and absorption enhancer[2].
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 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]. AT-1002 treatment results in 3-fold increase in phosphotyrosine content of zonula occludens-1 (ZO-1)[2].
