Investigations of SCIO-469-like compounds for the inhibition of p38 MAP kinase
摘要:
The p38 MAP kinase is implicated in the release of the pro-inflammatory cytokines TNF alpha and IL-1b. Inhibition of cytokine release may be a useful treatment for inflammatory conditions such as rheumatoid arthritis and Crohn's disease. A new lead structure for p38 MAP kinase inhibition was identified. Herein, we report the SAR of this new class of p38 inhibitors. (C) 2009 Elsevier Ltd. All rights reserved.

There is currently an unmet need for the development of small-molecule therapeutics for norovirus infection. The piperazine scaffold, a privileged structure embodied in many pharmacological agents, was used to synthesize an array of structurally-diverse derivatives which were screened for anti-norovius activity in a cell-based replicon system. The studies described herein demonstrate for the first time that functionalized piperazine derivatives possess anti-norovirus activity. Furthermore, these studies have led to the identification of two promising compounds (6a and 9I) that can be used as a launching pad for the optimization of potency, cytotoxicity, and drug-like characteristics.
