  Synthesis of glycose carbamides and evaluation of the induction of erythroid differentiation of human erythroleukemic K562 cells

  摘要：

  A series of carbamides derived from 1,2:5,6-di-O-isopropylidene-D-gluco- (1) and D-allofuranose (3) as well as their 5,6-O-deprotected analogues (2 and 4) and methyl 3,4-O-isopropylidene-alpha- and beta-D-galactopyranosides (5 and 6) have been prepared in order to evaluate their ability to induce erythroid differentiation of human erythroleukemic K562 cells. Twenty out of 51 carbamides tested exhibit an appreciable activity as inducers of erythroid differentiation and have been fully characterized and described. (c) 2008 Elsevier Masson SAS.

  Multiple sclerosis is a chronic inflammatory demyelinating disorder of the central nervous system that eventually leads to progressive neurodegeneration and disability. Recent findings highlighted the emerging role of each target of the endocannabinoid system in controlling the symptoms and disease progression of multiple sclerosis. Therefore, multi-target modulators of the endocannabinoid system could provide a more effective pharmacological strategy as compared to the single target modulation. In this work, N-cycloheptyl-1,2-dihydro-5-bromo-1-(4-fluorobenzyl)-6-methyl-2-oxo-pyridine-3-carboxamide (B2) was identified as the most promising compound with dual agonism at cannabinoid receptors type-1 and cannabinoid receptors type-2 and good drug-like properties. In in vitro assays, B2 reduced glutamate release from rat synaptosomes through interaction with cannabinoid receptors type-1 and modulated the production of the pro- and anti-inflammatory cytokines (interleukins IL-1β and IL-6 and interleukin IL-10 respectively) via cannabinoid receptors type-2 activation. Furthermore, B2 demonstrated antinociceptive effects in an animal model of neuropathic pain and efficacy in an experimental autoimmune encephalomyelitis model of multiple sclerosis.
