RESEARCH
SUPPORT
2 P01 DA09158 (PD = A. Makriyannis) 5/15/2007–4/30/12
Endocannabinoid Active Sites as Therapeutic Targets:
The major goals of this core project involve: (1) the production of radiolabeled and
nonradiolabeled analogs in sufficient quantities to address the needs of the research
laboratories involved in the four related projects; (2) the biochemical and
pharmacological characterization of these compounds; (3) the development of epitope
tagged CB1 and CB2 constructs and their expression in mammalian cells; and, (4) the
preparation of antibodies for the CB1 and CB2 receptors.
Role: PI of Chemistry/Biochemistry/Cell Biology/Pharmacology Core
1 RO3 DA024842-01 (PD = R. Duclos) 4/01/2008–3/31/10 (NCE to 3/31/11)
Inhibition of Endocannabinoid Biosynthesis via Diacylglycerol Lipase:
The goal of this research was to develop highly selective bioavailable inhibitors of
diacylglycerol lipase, the primary enzyme responsible for the biosynthesis of the
endogeneous cannabinoid 2-arachidonoylglycerol, to probe endocannabinoid signaling.
