(S)-3-(1H-吲哚-3-基)-N-((1-(4-甲氧基苯基)环己基)甲基)-2-(3-(4-硝基苯基)脲基)丙酰胺

IC50: 4.8 μM (BRS-3)

ML-18 inhibits specific ¹²⁵ I-BA1 (DTyr-Gln-Trp-Ala-Val-βAla-His-Phe-Nle-NH2)BB6-14 binding to NCI-H1299 lung cancer cells stably transfected with BRS-3 with IC ₅₀ values of 4.8 μM. ML-18 binds with lower affinity to the GRPR and NMBR with IC ₅₀ values of 16 and more than 100 μM, respectively. ML-18 at 16 μM inhibits the ability of 10 nM BA1 to elevate cytosolic Ca ²⁺ in a reversible manner using lung cancer cells loaded with FURA2-AM. ML-18 at 16 μM inhibits the ability of 100 nM BA1 to cause tyrosine phosphorylation of the EGFR and ERK in lung cancer cells. It inhibits the proliferation of lung cancer cells.
