Biological Activity: KS-133 is a bicyclic peptide with VIPR2 antagonistic activity that can cross the blood-brain barrier. KS-133 selectively blocks VIPR2-mediated Gq/Ca, Gs/cAMP, cAMP/PKA/ERK and PI3K/AKT/GSK3β signaling pathways. KS-133 inhibits VIPR2 agonist-induced CREB phosphorylation in the prefrontal cortex of mice. KS-133 shifts the polarization direction of macrophages toward M1. KS-133 attenuates cancer cell proliferation and reduces the cell cycle distribution level at the S-M phase. KS-133 exerts antitumor effects in a mouse model of colorectal cancer. KS-133 reverses cognitive decline in mouse models of psychiatric disorders. KS-133 can be used for research related to schizophrenia, colorectal cancer and breast cancer[1][2][3][4].
