8-Nitrobenzothiazinones (BTZs) are a promising class of antimycobacterial agents currently under investigation in clinical trials. Starting from thiourea derivatives, a new synthetic pathway to BTZs was established. It allows the formation of the thiazinone ring system in one synthetic step and is applicable for preparation of a wide variety of BTZ analogues. The synthetic procedure furthermore facilitates the replacement of the sulphur atom in the thiazinone ring system by oxygen or nitrogen to afford the analogous benzoxazinone and quinazolinone systems. 36 BTZ analogues were prepared and tested in luminescence-based assays for in vitro activity against Mycobacterium tuberculosis (Mtb) using the microdilution broth method and a high-throughput macrophage infection assay.

A series of xanthine compounds derived from the previous hit 20i with modification on the terminal side chain was discovered through ring formation strategy. Systematic optimization of the compounds with rigid heterocycles in the hydrophobic side chain led to the new lead compound HBK001 (21h) with the improved DPP-IV inhibition and moderate GPR119 agonism activity in vitro. As a continuing work to further study the PK and PD profiles, 21h and its hydrochloride (22) were synthesized on grams scale and evaluated on the ADME/T and oral glucose tolerance test (OGTT) in ICR mice. Compound 22 showed the improved bioavailability and blood glucose-lowering effect in vivo compared to its free base 21h probably attributed to its improved solubility and permeability. The preliminary toxicity studies on compound 22 exhibited that the result of mini-Ames was negative and the preliminary acute toxicity LD50 in mice was above 1.5 g/kg, while it showed moderate inhibition on hERG channel with IC50 4.9 μM maybe due to its high lipophilicity. These findings will be useful for the future drug design for more potent and safer dual ligand targeting DPP-IV and GPR119 for the treatment of diabetes.

A series of (4β-substituted)-l-prolylpyrrolidine analogs lacking the electrophilic nitrile function were synthesized and their dipeptidyl peptidase IV (DPP-IV) inhibitory activity and duration of ex vivo activity were evaluated. Structural optimization of a N-(3-phenyl-1,2,4-thiadiazol-5-yl)piperazine analog 8, which was found by high-speed analog synthesis, was carried out to improve the potency and duration of action. A representative compound 26 was evaluated to assess its effect on the plasma glucose level after the oGTT (oral glucose tolerance test) in normal rats. Structure-activity relationships (SAR) are also presented.
