synthesis and anti-inflammatory performance of newly cyclizine derivatives on adult male wistar rats
cyclizine (1-benzhydryl-4-methyl-piperazine, cas 82-92-8, cyc, i), a piperazine derivative, belongs to h1 antihistamine group of drugs that shows such pharmacological properties as anti-inflammatory, anti-allergic and anti-platelet effects, similar to other h1-receptor antagonists. in this study, two new tolyl and cumene derivatives of i (1-ethyl-4-[(p-isopropylphenyl) (p-tolyl) methyl]-piperaz...
HIV-1 infection of the brain and PAF neurotoxicity are implicated in AIDS dementia complex. We previously reported that a trisubstituted piperazine derivative is able to diminish both HIV-1 replication in monocyte-derived macrophages and PAF-induced platelet aggregation. We report in this work new compounds obtained by modifying its piperazine substituents. The structure-activity relationship s...
Due to its environmentally benign character, supercritical carbon dioxide (scCO2) is considered in green chemistry, as a substitute for organic solvents in chemical reactions. In this paper, an innovative approach for preparation of flame retardant cotton fabric was obtained by utilizing supercritical carbon dioxide with co-solvent. A novel phosphorusnitrogen containing piperazine derivative, t...
Glucuronides of piperazine hydroxylamines are rarely reported in the literature, and even more rarely are their structures unambiguously identified. One major metabolite was detected by liquid chromatography/mass spectrometry-radioactivity in urine from monkeys treated with the aryl piperazine oral hypoglycemic agent 9-[(1S,2R)-2-fluoro-1-methylpropyl]-2-methoxy-6-(1-piperazinyl) purine hydroch...

THE TITLE COMPOUND (SYSTEMATIC NAME 4-{3-[2-aza-tricyclo-[9.4.0.0(3,8)]penta-deca-1(15),3,5,7,11,13-hexaen-2-yl]prop-yl}-1-(2-hy-droxy-eth-yl)piperazine-1,4-diium dichloride), C(23)H(31)N(3)O(+)·2Cl(-), is the dihydro-chloride of a piperazine derivative bearing a bulky 3-(5H-dibenz[b,f]azepin-5-yl)propyl substituent. Protonation took place on both N atoms of the piperazine unit. The diaza-cyclo...
Metabolites of a G protein-coupled receptor modulator containing 1,2,4-oxadiazole and piperazine substructures were identified in vitro in human, rat, and dog hepatocyte incubates and in vivo in rat plasma, bile, urine, and feces by using 14C-radiolabeled parent compound. Exposure coverage for the major circulating metabolites in humans at steady state and in preclinical species used in drug sa...
Novel, functionalized piperazine derivatives were successfully synthesized and fully characterized by 1H/13C/19F NMR, MS, elemental analysis and lipophilicity. All piperazine compounds occur as conformers resulting from the partial amide double bond. Furthermore, a second conformational shape was observed for all nitro derivatives due to the limited change of the piperazine chair conformation. ...
