A series of pyrrole-indolin-2-ones were synthesized, and their inhibition profile for Aurora kinases was studied. The potent compound 33 with phenylsulfonamido at the C-5 position and a carboxyethyl group at the C-3' position selectively inhibited Aurora A over Aurora B with IC(50) values of 12 and 156 nM, respectively. Replacement of the carboxyl group with an amino group led to compound 47, which retained the activity for Aurora B and lost activity for Aurora A (IC(50) = 2.19 mu M). Computation modeling was used to address the different inhibition profiles of 33 and 47. Compounds 47 and 36 (the ethyl ester analogue of 33) inhibited the proliferation of HCT-116 and HT-29 cells and suppressed levels of the phosphorylated substrates of Aurora A and Aurora B in the Western blots.

we reported the inhibitionprofiles of 4′‐acylpyrrole–5‐fluoroindolin‐2‐one3 with a C‐3′ sidechain for VEGFR2, PDGFR‐β, and FGFR‐1proteinkinases. The pyrrole‐fused cyclohexanone moiety provided 3 with the best potency to inhibit the three kinases, and the C‐3′ sidechains contributed to the different inhibitionprofiles of 3. Compound 3b with a C‐3′ 2‐carboxylethyl sidechain showed good potency
