Antagonist G is a potent vasopressin antagonist. Antagonist G is also a weak antagonist of GRP and Bradykinin. Antagonist G induces AP-1 transcription and sensitizes cells to chemotherapy[1][2].

In Vitro	Antagonist G (0-100 μM) induces apoptosis is redox-sensitive and caspase-dependently in SCLC cells[2]. Antagonist G activates JNK1 in SCLC cells[2]. Antagonist G is not intrinsically a free radical oxygen donor but stimulates free radical generation specifically within SCLC cells (6.2-fold) and increases the activity of the redox-sensitive transcription factor AP-1 by 61%[2]. Cell Viability Assay[2] Cell Line: SCLC cell lines NCI-H69, NCI-H510 and CHO-K1 cells. Concentration: 0-100 μM. Incubation Time: 24 h. Result: Inhibited cell growh.
