Objective. To evaluate antinocicpetive and redox properties of the monoterpenes (+)-camphene, p-cymene, and geranyl acetate in in vivo and in vitro experimental models. Methods. Evaluation of the in vitro antioxidant activity of (+)-camphene, p-cymene, and geranyl acetate using different free radical-generating systems and evaluation of antinociceptive actions by acetic acid-induced writhing an...

The dimer [{(?6-p-cymene)RuCl}2(?-Cl)2] (cymene=MeC6H4iPr) reacts with N,N?-bis(p-tolyl)-N??-(2-pyridinylmethyl)guanidine (H2L1) and N,N?-bis(p-tolyl)-N??-(2-diphenylphosphanoethyl)guanidine (H2L2), in the presence of NaSbF6, giving rise to chlorido compounds formula [(?6-p-cymene)RuCl(H2L)][SbF6] (H2L=H2L1 (1), H2L2 (2)) which guanidine ligand adopts a ?2 chelate coordination mode. related (S)...

The essential oil of Clausena anisum-olens (Blanco) Merr. showed strong contact toxicity and repellency against Lasioderma serricorne and Liposcelis bostrychophila adults. The components of the essential oil obtained by hydrodistillation were determined by gas chromatography-mass spectrometry. It was found that the main components were myristicin (36.87%), terpinolene (13.26%), p-cymene-8-ol (1...

We present the synthesis and structural characterization of novel ruthenium complexes containing C^C* cyclometalated N-heterocyclic carbene ligands, η(6)-arene (p-cymene) ligands and one bridging chlorine ion. Complexes of the general formula [Ru(p-cymene)(C^C*)Cl] were prepared via a one-pot synthesis using in situ transmetalation from the correspondent silver NHC complexes. These complexes re...

A chiral supramolecular assembly encapsulates the two cationic ruthenium sandwich complexes [CpRu(eta(6)-C(6)H(6))](+) and [CpRu(p-cymene)](+). The host-guest complexes K(11)[CpRu(eta(6)-C(6)H(6)) subset Ga(4)L(6)] (2) and K(11)[CpRu(p-cymene) subset Ga(4)L(6)] (3) were characterized by one- and two-dimensional NMR techniques as well as by electrospray mass spectrometry. Encapsulation of the pr...

A cymene-derived drug, 3-[4'-(o-ethoxyphenyl)piperazin-1'-yl]-ethyloxy-p-cymene+ ++ (B1178), is not significantly metabolized by fungal microorganisms. On the contrary, one of its metabolites in rat, 3-(piperazin-1'-yl)ethoxy-p-cymene (B1071), is quantitatively converted by Cunninghamella echinulata NRRL 3655 into two hydroxylated products: the corresponding phenol derivative and a benzylic alc...

The treatment of [Ru(η6-p-cymene)Cl2]2 with N,N’-(1,2-phenylene)dipicolinamide (H2L1) afforded the double salt complex [{Ru(η6-p-cymene)2-µ-Cl}L1][Ru(η6-p-cymene)Cl3], (Ru1) in moderate yields. Separately, reactions ligands (H2L1), N,N’-(4,5 dimethyl-1,2-phenylene)dipicolinamide (H2L2), and N,N’-(4-methoxy-1,2-phenylene)dipicolinamide (H2L3) presence KPF6 respective dinuclear half-sandwich Ru(I...

The title compound, [Ru(C7F5O2)2(C10H14)(C21H24N2)]·2CH2Cl2, is formed as an orange crystalline powder by the reaction of RuCl2(p-cymene)(IMes) and AgOCOC6F5 in anhydrous tetra-hydro-furan (IMes = 1,3-dimesityl-2,3-di-hydro-1H-imidazol-2-yl-idene). The asymetric unit consists of two independent [Ru(C6F5COO)2(η(6)-p-cymene)(IMes)] com-plexes and four dichloro-methane solvent mol-ecules. In each ...

The light-protected reaction of [(eta(6)-p-cymene)Ru(II)Cl(2)](2) with 1-(2-hydroxyethyl)piperazine in dry methanol, followed by addition of excess NH(4)PF(6), afforded the complex [(eta(6)-p-cymene)Ru(II)(NH(3))(2)Cl](PF(6)) () in 47% yield. Attempts to use the same protocol for the synthesis of [(eta(6)-p-cymene)Os(II)(NH(3))(2)Cl](PF(6)) led to the isolation of the binuclear triply methoxido...
