ML-18 (the S-enantiomer, the enantiomer is EMY-98), a nonpeptide analogs of PD176252, is a BRS-3 (Bombesin receptor subtype 3) antagonist with an IC50 of 4.8 μM. ML-18 and EMY-98 inhibited specific (125)I-BA1 (DTyr-Gln-Trp-Ala-Val-βAla-His-Phe-Nle-NH2)BB(6-14) binding to NCI-H1299 lung cancer cells stably transfected with BRS-3 with IC50 values of 4.8 and >100μM, respectively. In contrast, ML-18 bound with lower affinity to the GRPR and NMBR with IC50 values of 16 and >100μM, respectively.
