Drug compliance is critical for patients with chronic diseases such as diabetes. In our continuous effort to find better glucose-lowering agents, an exploration for long-acting DPP-4 inhibitors had been launched. Based on our previously reported compounds bearing a pyrrolopyrimidine scaffold, the lead compound 4a (IC50 = 2.3 nM, t1/2(rat) = 5.46 h) with pharmacokinetic superiority was rapidly determined. Further SAR study indicated that the pyrrole ring was generally tolerable for variation, in which a β-substitution gave a better DPP-4 affinity. In depth evaluation of the pyrrole ring β position identified a highly potent compound 12a (IC50 = 0.76 nM, t1/2(rat) = 7.89 h). In vivo pharmacodynamics tests demonstrated similar or even slightly better sustained DPP-4 inhibition for compounds 4a and 12a compared with the first marketed once-weekly drug trelagliptin in this category, indicating that improvements to DPP-4 inhibitory activity or pharmacokinetic profile might be feasible ways to rapidly generate long-acting DPP-4 inhibitors.

SET domain bifurcated protein 1 (SETDB1) is a histone lysine methyltransferase that promotes the silencing of some tumour suppressor genes and is overexpressed in many cancers. SETDB1 contains a unique tandem tudor domain (TTD) that recognizes histone H3 sequences containing both methylated and acetylated lysines. Beginning with the identification of a hit compound (Cpd1), we discovered the first potent and selective small molecule SETDB1-TTD inhibitor (R,R)-59 through stepwise structure-guided optimization. (R,R)-59 showed a KD value of 0.088±0.045 μM in the ITC assay. The high potency of (R,R)-59 was well explained by the cocrystal structure of the (R,R)-59-TTD complex. (R,R)-59 is an endogenous binder competitive inhibitor. Evidence has also demonstrated its cellular target engagement. Interestingly, the enantiomer (S,S)-59 did not show activity in all the assays, highlighting the potential of (R,R)-59 as a tool compound in exploring the biological functions of SETDB1-TTD.

Herein, we report the discovery of a series of new P300/CBP-associated factor (PCAF) bromodomain (BRD) inhibitors, which were obtained through a hit discovery process and subsequent structure-based optimization and structure-activity relationship analyses toward a retrieved hit compound (12). Among these inhibitors, (R,R)-36n is the most potent one with an IC50 of 7 nM in homogeneous time-resolved fluorescence assay and a KD of 78 nM in isothermal titration calorimetry assay. This compound also exhibited activity against GCN5 and FALZ, but weak or no activity against other 29 BRD proteins and 422 kinases, indicating considerable selectivity. X-ray cocrystal structure analysis revealed the molecular interaction mode and the precise stereochemistry required for bioactivity. Cellular activity, preliminary RNA-seq analysis, and pharmacokinetic properties were also examined for this compound. Collectively, this study provides a versatile tool molecule to explore molecular mechanisms of PCAF BRD regulation and also offers a new lead compound for drug discovery targeting PCAF.

A novel dipeptidyl peptidase IV inhibitor hit (5, IC50 = 0.86 μM) was structurally derived from our recently disclosed preclinical candidate 4 by replacing the cyanobenzyl with a butynyl based on pharmacophore hybridization. A hit-to-lead optimization effort was then initiated to improve its potency. Most N-substituted analogs exhibited good in vitro activity, and compound 18o (IC50 = 1.55 nM) was identified to be a potent dipeptidyl peptidase IV inhibitor with a significantly improved pharmacokinetic properties (bioavailablity: 41% vs 82.9%; T1/2: 2 h vs 4.9 h).

We previously reported a highly potent DPP-IV inhibitor 6 with low in vivo efficacy. While trying to maintain consistent in vitro and in vivo biological activity, we initiated a pharmacokinetic property-driven optimization to improve the metabolic stability and permeability of inhibitor 6. A simple scaffold replacement of thienopyrimidine with pyrrolopyrimidine (21a) led to significantly improved metabolic stability (4% vs. 65% remaining). Further modification of the pyrrolopyrimidine scaffold to produce compound 21j resulted in much better oral bioavailability than 6. Importantly, compound 21j exhibits greater in vivo efficacy than does 6 and Alogliptin and is worthy of further development.
