Sentrin-specific proteases (SENPs) are responsible for the maturation of small ubiquitin-like modifiers (SUMOs) and the deconjugation of SUMOs from their substrate proteins. Studies on prostate cancer revealed an overexpression of SENP1, which promotes prostate cancer progression as well as metastasis. Therefore, SENP1 has been identified as a novel drug target against prostate cancer. Herein, we report the discovery and biological evaluation of potent and selective SENP1 inhibitors. A structure-activity relationship (SAR) of the newly identified pyridone scaffold revealed allosteric inhibitors with very attractive in vitro ADMET properties regarding plasma binding and plasma stability for this challenging target. This study also emphasizes the importance of biochemical mode of inhibition studies for de novo designed inhibitors.

An efficient synthesis of (S)-(-)-acromelobic acid (1) and (S)-(-)-acromelobinic acid (2) is described via asymmetric hydrogenation protocol. Asymmetric hydrogenation of dehydroamino acid derivative 23 using (R,R)-[Rh(DIPAMP)(COD)]BF4 catalyst followed by removal of the protective groups afforded (S)-(-)-acromelobic acid (1) in >98% ee. The key intermediate 23 was prepared from citrazinic acid (8). The dehydroamino acid derivative 33 required for the synthesis of (S)-(-)-2 was prepared from 2,5-lutidine (27), which upon hydrogenation using (S,S)-[Rh(Et-DuPHOS)(COD)]BF4 catalyst afforded (S)-(+)-34 in 93% yield and >96% ee. Removal of protective groups in (S)-(+)-34 afforded (S)-(-)-acromelobinic acid (2) in good overall yield.

(Equation Presented) A highly efficient enantioselective synthesis of (S)-(-)-acromelobic acid (1) was achieved via asymmetric hydrogenation of dehydroamino acid derivative (3) using (R,R)-[Rh(DIPAMP)(COD)]BF4 catalyst followed by removal of protective groups in >98% ee and good over all yield. The key intermediate (3) was prepared from the commercially available citrazinic acid (4) in six steps.
