Hydroxamic Acids Block Replication of Hepatitis C Virus
摘要:
Intrigued by the role of protein acetylation in hepatitis C virus (HCV) replication, we tested known histone deacetylase (HDAC) inhibitors and a focused library of structurally simple hydroxamic acids for inhibition of a HCV subgenomic replicon. While known HDAC inhibitors with varied inhibitory profiles proved to be either relatively toxic or ineffective, structureactivity relationship (SAR) studies on cinnamic hydroxamic acid and benzo[b]thiophen-2-hydroxamic acid gave rise to compounds 22 and 53, which showed potent and selective anti-HCV activity and therefore are promising starting points for further structural optimization and mechanistic studies.
Discovery of Potent, Orally Available Vanilloid Receptor-1 Antagonists. Structure−Activity Relationship of N-Aryl Cinnamides
摘要:
The vanilloid receptor-1 (TRPV1 or VR1) is a member of the transient receptor potential (TRP) family of ion channels and plays a role in regulating the function of sensory nerves. A growing body of evidence demonstrates the therapeutic potential of TRPV1 modulators: particularly in the management of pain. As a result of our screening efforts, we identified (E)-3-(4-tert-butylphenyl)-N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)acrylamide (1): an antagonist that blocks the capsaicin-induced and pH-induced uptake of Ca-45(2+) in TRPV1-expressing Chinese hamster ovary cells with IC50 values of 17 +/- 5 and 150 +/- 80 nM, respectively. In this report.. we describe the synthesis and structure-activity relationship of a series of N-aryl cinnamides, the most potent of which (49a and 49b) exhibit good oral bioavailability in rats (F-oral = 39% and 17%. respectively).
