Endocannabinoids (eCBs) are endogenous neuromodulators of synaptic transmission. Their dysfunction may cause debilitating disorders of diverse clinical manifestation. For example, drug addiction, lack of sex desire, eating disorders, such as anorexia or bulimia and dyssomnias. eCBs also participate in the regulation of core temperature and pain perception. In this context, it is important to recognize the utility of cannabinoid receptor 1 (CB1R) agonists, natural as Δ9-tetrahydrocannabinol (THC) or synthetic as Nabilone as useful drugs to alleviate this kind of patients' suffering. Therefore, we have developed a new drug, (R,Z)-18-((1S,4S)-5-methyl-2,5-diazabicyclo[2.2.1]heptan-2-yl)-18-oxooct adec-9-en-7-yl phenylacetate (PhAR-DBH-Me), that appears to bind and activate the CB1R. This diazabicyclic amide was synthesized from phenylacetylricinoleic acid and (1S,4S)-2,5-diazabicyclo[2.2.1]heptane. To test its cannabinergic properties we evaluated its effects on core temperature, pain perception, and the sleep-waking cycle of rats. Results indicate that 20 and 40 mg/kg of PhAR-DBH-Me readily reduced core temperature and increased pain perception threshold. In addition, 20 mg/kg increased REM sleep in otherwise normal rats. All these effects were prevented or attenuated by AM251, a CB1R antagonist. Place preference conditioning studies indicated that this molecule does not produce rewarding effects. These results strongly support that PhAR-DBH-Me possesses cannabinoid activity without the reinforcement effects.
Asymmetric synthesis of 3-amino-4-hydroxy-2-(hydroxymethyl)pyrrolidines as potential glycosidase inhibitors

Three diastereoisomers of 3-amino-4-hydroxy-2-(hydroxymethyl)pyrrolidine have been synthesised by a divergent route starting from trans-4-hydroxy-l- proline. Regio- and stereoselective introduction of the 3-amino and 4-hydroxyl functional groups was achieved using either a tethered aminohydroxylation reaction or by employing intra- and intermolecular epoxide-opening strategies. Preliminary biological data indicate that two of these novel amino pyrrolidines are moderate inhibitors of β-galactosidase. The Royal Society of Chemistry.

The novel (2S,3S,4R)-3-amino-2-hydroxymethyl-4-hydroxypyrrolidine 5 has been produced in an efficient synthesis from trans-4-hydroxy-l-proline 8. The key step involves a tethered aminohydroxylation of the alkene 7 to introduce regio- and stereoselectively

trans-4-hydroxy-L-proline (5) has been elaborated into a new series of pyrrolidine-L-nucleoside analogues incorporating non-standard 5-substituted- pyrimidine nucleobases, via the azidopyrrolidines 12 and 13. Those analogues employing an acyl protecting group on the primary hydroxyl functionality underwent radical bromination of the ethyl side chain of the pyrimidine ring, to provide E-5-(2-bromovinyl)uracil-pyrrolidine-L-nucleosides 23-26. Of the compounds assessed for potential antiviral activity only 5-ethyluracil- (benzoyloxymethyl)pyrrolidine 20 was found to be a specific inhibitor of vaccinia virus.
