Platelet MAO activity was affected by preincubation with cannabinoid derivatives in vitro. The psycho-active derivative delta 1-THC inhibited MAO activity in platelets to an extent varying according to its concentration while CBD and (+) delta 6-THC had no inhibitory effect. (-) delta 6-THC, which
The present overview covers various aspects of research going on in the Cannabis field in the Department of Natural Products at the Hebrew University. In the first part we discuss, and try to explain, the reason for the absence of the term Cannabis (and possibly also opium) in the Old Testament. In
MAb against delta 1-THCA was produced by fusing hybridoma with splenocytes immunized with delta 1-THCA-BSA conjugate and hypoxanthine, aminopterine, thymidine-sensitive mouse myeloma cell line, P3-X63-Ag8-653. The cross-reaction of anti-delta 1-THCA antibody against other cannabinoids was very wide,
The synthesis of the (2R,3R,4S,6R)-7/(2S,3S,4R,6S)-8 enantiomeric pair of benzofuran cannabinoids is reported together with the 1H and 13C NMR spectral parameters. In benzofuran 8 the configurational arrangement of ligated groups at the stereogenic C(3) atom (through which the terpene moiety is
Stereospecificity has been reported for a number of actions of the cannabinoids in a variety of systems. In the present report, we have shown that this effect can also be demonstrated when human lung fibroblasts in monolayer culture are stimulated by cannabinoids to produce prostaglandin E2 (PGE2).
The phospholipases controlling the release of arachidonic acid in mouse peritoneal macrophages have been shown to be stimulated by the natural psychoactive cannabinoids. A close correlation was observed between the potencies of these substances in elevating arachidonate levels in vitro and the
1. In anaesthetized rats, intravenous administration of cannabis extract (10 mg/kg), Delta(1)-tetrahydrocannabinol (THC) (0.5 mg/kg) and Delta(6)-THC (0.5 mg/kg) caused a reduction in systemic blood pressure, pulse rate and respiratory rate.2. Neither cannabinol (1 mg/kg, i.v.) nor cannabidiol (1
