Ki16198 is a potent and orally active LPA receptor antagonist, the methyl ester of Ki16425 (HY-13285). Ki16198 inhibits LPA₁ and LPA₃-induced inositol phosphate production with K_i values of 0.34 μM and 0.93 μM, respectively. Ki16198 is effective for pancreatic cancer tumorigenesis and metastasis in vivo^[1].

Ki: 0.34 μM (LPA1 receptor)
Ki: 0.93 μM (LPA1 receptor)^[1]

Ki16198 (0-10 μM; 48 hours) is effective to inhibit migration and invasion responses to LPA with a potency similar to that of Ki16425. The inhibitory effects Ki16198 on the invasion response to LPA, but not to EGF in several pancreatic cancer cell lines, including Panc-1,CFPAC-1, and BxPC-3 cells^[1].
Ki16198 (10 μM; 48 hours) signifivcantly decreases expression of proMMP-9 protein and mRNA expression in YAPC-PD cells^[1].

Ki16198 (oral administaion; 1 mg in 500 ul; 28 days) significantly decreases the degree of metastasis activity in Ki16198-treated mice. Similiar to liver, metastasis to lung and brain in mice is also observed^[1].
