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.

Paragraph 0344, (2018/05/24)
Provided is a novel low-molecular-weight compound that suppresses production of induction type MMPs, particularly MMP-9, rather than production of hemostatic type MMP-2. The present invention relates to a compound represented by the following formula (I): wherein each symbol is as described in the DESCRIPTION. The compound has a selective MMP-9 production suppressive action, and is useful as a drug for the prophylaxis and/or treatment of autoimmune diseases such as rheumatoid arthritis and the like, inflammatory bowel diseases (ulcerative colitis, Crohn's disease) or osteoarthritis.
General synthetic strategies towards N-alkyl sulfoximine building blocks for medicinal chemistry and the use of dimethylsulfoximine as a versatile precursor

The sulfoximine group has great potential as a substituent in drug discovery, as evidenced by two new clinical candidates, and can be viewed as an isosteric alternative to the commonly used sulfone. Our aim was to improve the accessibility of this group by synthesising a diverse range of S-alkyl and N-alkyl sulfoximine building blocks with procedures that are applicable on a practical scale (>10 g). In particular, synthesis of the less well exploited N-alkyl sulfoximines and the use of dimethylsulfoximine as a versatile, commercially available precursor is discussed.
