Novel benzofuran-2-carboxylic acids, exemplified by 29, 38 and 39, have been discovered as potent Pim-1 inhibitors using fragment based screening followed by X-ray structure guided medicinal chemistry optimization. The compounds demonstrate potent inhibition against Pim-1 and Pim-2 in enzyme assays.

The coumarinic acid-based cyclic DADLE (H-Tyr-D-Ala-Gly-Phe-D-Leu-OH) prodrug 1a exhibited more favorable physicochemical properties than did DADLE for permeation across the intestinal mucosa. However, prodrug 1a, whose bioconversion to DADLE was slow, was subject to extensive biliary clearance when administered to
