Hit-to-lead evaluation of a novel class of sphingosine 1-phosphate lyase inhibitors
摘要:
Inhibition of sphingosine-1-phosphate lyase has recently been proposed as a potential treatment option for inflammatory disorders such as multiple sclerosis, rheumatoid arthritis, and inflammatory bowel disease. In this report we describe our hit-to-lead evaluation of the isoxazolecarboxamide 6, a high-throughput screening hit (in vitro IC50 = 1.0 mu M, cell IC50 = 1.8 mu M), as a novel S1P lyase inhibitor. We were able to establish basic structure-activity relationships around 6 and succeeded in obtaining X-ray structural information which enabled structure-based design. With the discovery of 28, enzyme activity was quickly improved to IC50 = 120 nM and cell potency to IC50 = 230 nM. The main liability in the established isoxazolecarboxamide hit series was determined to be metabolic stability. In particular we identified that future lead-optimization efforts to overcome this problem should focus on blocking the N-dealkylation on the secondary amine. (C) 2016 Elsevier Ltd.

The present invention provides isoindolinone and pyrrolopyridinone derivatives, as well as their compositions and methods of use, that inhibit the activity of the serine/threonine kinase, Akt, and are useful in the treatment of diseases related to the activity of Akt including, for example, cancer and other diseases.
A metal-free, photosensitized regioselective diamination of alkene is reported. The keys to this advance are: 1) rational design of bifunctional diamination reagent, 2) simultaneous generation of long-lived iminyl radical and transient amidyl radical with significantly differed reactivities, and 3) involvement of photoinduced energy transfer reaction mode.
