Synthesis and SAR of novel imidazoquinoxaline-Based Lck inhibitors: improvement of cell potency
摘要:
A series of anilino(imidazoquinoxaline) analogues bearing solubilizing side chains at the 6- and 7-positions of the fused phenyl ring has been prepared and evaluated for inhibition against Lck enzyme and of T-cell proliferation. Significant improvement of the cellular activity was achieved over the initial lead, compound 2. (C) 2002 Elsevier Science Ltd. All rights reserved.
Reaction of quinoxalin-2-ones with TosMIC reagent: synthesis of imidazo[1,5-a]quinoxalin-4-ones
摘要:
Imidazo[1,5-alpha ]quinoxalin-4-ones were prepared in four steps starting from 1,2-phenylenediamines using a new strategy for the construction of the ring system. A key step in this new method involves the reaction of quinoxalin-2-ones with TosMIC (tosylmethyl isocyanide). (C) 2001 Elsevier Science Ltd. All rights reserved.
