Indoleamine 2,3-dioxygenase-1 (IDO1) is a potential target for the next generation of cancer immunotherapies. We describe the development of two series of IDO1 inhibitors incorporating a N-hydroxy-thiophene-carboximidamide core generated by knowledge-based drug design. Structural modifications to improve the cellular activity and pharmacokinetic (PK) properties of the compounds synthesized, including extension of the side chain of the N-hydroxythiophene-2-carboximidamide core, resulted in compound 27a, a potent IDO1 inhibitor which demonstrated significant (51%) in vivo target inhibition on IDO1 in a human SK-OV-3 ovarian xenograft tumor mouse model. This strategy is expected to be applicable to the discovery of additional IDO1 inhibitors for the treatment of other diseases susceptible to modulation of IDO1.

We have identified 5-(3-chlorothiophen-2-yl)-3-(4-trifluoromethylphenyl)-1, 2,4-oxadiazole (1d) as a novel apoptosis inducer through our caspase- and cell-based high-throughput screening assay. Compound 1d has good activity against several breast and colorectal cancer cell lines but is inactive against several other cancer cell lines. In a flow cytometry assay, treatment of T47D cells with 1d resulted in arrest of cells in the G1 phase, followed by induction of apoptosis. SAR studies of Id showed that the 3-phenyl group can be replaced by a pyridyl group, and a substituted five-member ring in the 5-position is important for activity. 5-(3-Chlorothiophen-2-yl)-3-(5- chloropyridin-2-yl)-1,2,4-oxadiazole (41) has been found to have in vivo activity in a MX-1 tumor model. Using a photoaffinity agent, the molecular target has been identified as TIP47, an IGFII receptor binding protein. Therefore, our cell-based chemical genetics approach for the discovery of apoptosis inducers can identify potential anticancer agents as well as their molecular targets.
