The design and synthesis of novel orally active inhibitors of AP-1 and NF-κB mediated transcriptional activation. SAR of In vitro and In vivo studies
摘要:
We have developed novel orally active quinazoline analogues as inhibitors of AP-1 and NF-kappaB mediated transcriptional activation. Among the derivatives prepared, 1-[2-(2-thienyl)quinazolin-4-ylamino]-3-methyl-3-pyrroline-2,5-dione (10) showed significant activity in an adjuvant-induced arthritis rat model by reducing the swelling by 65% in the non-injected foot. The synthesis, structure-activity relationship, and in vivo activity are described. (C) 2003 Elsevier Ltd. All rights reserved.

The first heterogeneous carbonylative annulation of 2-aminobenzamides with aryl iodides was achieved in N,N-dimethylformamide (DMF) at 120 °C under 10 bar of carbon monoxide by using an MCM-41-immobilized bidentatephosphine palladium(II) complex [MCM-41-2P-Pd(OAc)2] as catalyst and 1,8-diazabicycloundec-7-ene (DBU) as base, yielding a wide variety of quinazolinone derivatives in good to excellent

Abstract An efficientone‐potsynthesis of 2‐aryl‐4(3H)‐quinazolinones from 2‐amino benzamides and substituted benzoyl chlorides in a room temperature ionicliquid is described. Compared with the classical reaction conditions, this new synthetic method has the advantages of recyclability of ionicliquid, very good to excellent yields (78–92%), the absence of hazardous and expensive catalysts, and easy

using an MCM-41-immobilized l-proline copper(I) complex [MCM-41-l-Proline-CuBr] as the catalyst and air as the oxidant, yielding a variety of quinazolinone derivatives in good yields. The new MCM-41-l-Proline-CuBr catalyst can easily be prepared from commercially readily available and inexpensive reagents and recovered by filtration of the reaction mixture, and reused up to seven times with almost consistent
