Dipeptidyl Peptidase-IV (DPP-4) is a validated therapeutic target for type 2 diabetes. Aiming to interact with both residues Try629 and Lys554 in S2′ site, a series of novel uracil derivatives 1a–l and 2a–i incorporating benzoic acid moieties at the N3 position were designed and evaluated for their DPP-4 inhibitory activity. Structure-activity relationships (SAR) study led to the identification of the optimal compound 2b as a potent and selective DPP-4 inhibitor (IC50 = 1.7 nM). Docking study revealed the additional salt bridge formed between the carboxylic acid and primary amine of Lys554 has a key role in the enhancement of the activity. Furthermore, compound 2b exhibited no cytotoxicity in human hepatocyte LO2 cells up to 50 μM. Subsequent in vivo evaluations revealed that the ester of 2b robustly improves the glucose tolerance in normal mice. The overall results have shown that compound 2b has the potential to a safe and efficacious treatment for T2DM.

A series of novel xanthine derivatives 2a-l incorporating benzoic acid moieties were rapidly generated by using strategy of scaffold-hopping from our previously reported scaffold uracil to xanthine, a scaffold of approved drug linagliptin. After systematic structure-activity relationship (SAR) study around benzoic acid moieties, 5 novel DPP-4 inhibitors with low picomolar potency range (IC50 50 value of 0.1 nM for DPP-4, showed 22-fold improvement in inhibitory activity compared to lead compound uracil 1, its activity was 45-fold more potent than alogliptin. 2e, 2f, 2i and 2k were selected for pharmacokinetic evaluation, and 2f and 2i showed the better pharmacokinetic profiles after iv administration, but poor oral bioavailability. To improve the oral pharmacokinetic profile, prodrug design approach was performed around 2f and 2i. Esters of 2f and 2i were synthesized and evaluated for stability, toxicity and pharmacokinetics. Compound 3e, the methyl ester of compound 2f, was identified to demonstrate good stability, low toxicity and improved oral bioavailability, with 3-fold higher blood concentration compared to 2f in rats. The following in vivo evaluations revealed 3e provided a sustained pharmacodynamics effect for 48h, and robustly improved glucose tolerance in normal ICR and db/db mice in dose-dependent manner. Chronic treatments investigations demonstrated that 3e achieved more beneficial effects on fasting blood glucose levels and glucose tolerance than alogliptin in type 2 diabetic db/db mice. The overall results have shown that compound 3e has the potential to efficacious, safety and long-acting treatment for T2DM.

A series of analogs of the immunomodulary drugs lenalidomide (1) and pomalidomide (2), in which the amino group is replaced with various isosteres, was prepared and assayed for immunomodulatory activity and activity against cancer cell lines. The 4-methyl and 4-chloro analogs 4 and 15, respectively, displayed potent inhibition of tumor necrosis factor-α (TNF-α) in LPS-stimulated hPBMC, potent stimulation of IL-2 in a human T cell co-stimulation assay, and anti-proliferative activity against the Namalwa lymphoma cell line. Both of these analogs displayed oral bioavailability in rat.

Based on the structural features of Indoprofen and PIB, a series of isoindol-1,3-diones 1a-k and isoindol-1-ones 2a-l were designed and synthesized. These 23 compounds were evaluated by competitive binding assay against aggregated Aβ42 fibrils using [125I]TZDM. All the isoindolone derivatives showed very good binding affinities with Ki values in the subnanomolar range (0.42-0.94 nM). Among them, isoindol-1,3-diones 1i and 1k and isoindol-1-ones 2c and 2i exhibited excellent binding affinities (Ki = 0.42-0.44 and 0.46-0.49 nM) than those of Indoprofen (Ki = 0.52 nM) and PIB (Ki = 0.70 nM). These results suggest that isoindolones could be served as a scaffold for potential AD diagnostic probes to monitor Aβ fibrils.
