There is provided compounds of formula (I): wherein R1, R2 and R3 have meanings given in the description, and pharmaceutically-acceptable esters, amides, solvates or salts thereof, which compounds are useful in the treatment of diseases in which inhibition of a protein or lipid kinase (e.g. PI3-K, particularly class I PI3K) is desired and/or required, and particularly in the treatment of cancer.
Disclosed are compounds of Formula (I), methods of using the compounds for inhibiting HPK1 activity and pharmaceutical compositions comprising such compounds. The compounds are useful in treating, preventing or ameliorating diseases or disorders associated with HPK1 activity such as cancer.
We previously reported a novel series of 1H-pyrazolo[3,4-c]pyridinederivatives and the identification of compound 4b as a highly potent GPR119 agonist. However, the advancement of preclinical evaluations of compound 4b is expected to be difficult because of the compound’s significantly poor aqueous solubility (0.71 μM at pH6.8). In this article, we describe the further optimization of compound 4b
我们先前报道了一系列新型的1 H-吡唑并[3,4- c ]吡啶衍生物,并将化合物4b鉴定为高效GPR119激动剂。但是,由于该化合物的水溶性差(在pH6.8下为0.71μM),因此很难进行化合物4b的临床前评估。在本文中,我们描述了化合物4b的进一步优化,重点是提高其水溶性。优化中央间隔基,左手的芳基和右手的哌啶N-封端基团导致鉴定出强效的GPR119激动剂3 H- [1,2,3]三唑[4,5- c ]]吡啶衍生物32o,具有改善的溶解度(在pH6.8下为15.9μM)。
Rapid generation of a novel DPP-4 inhibitor with long-acting properties: SAR study and PK/PD evaluation
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

In an effort to address potential cardiotoxicity liabilities identified with earlier frontrunner compounds, a number of new 3,5-diaryl-2-aminopyridine derivatives were synthesized. Several compounds exhibited potent antiplasmodial activity against both the multidrug resistant (K1) and sensitive (NF54) strains in the low nanomolar range. Some compounds displayed a significant reduction in potency in
