dimethylbenzene/dental caries

New phototriggered molecular machines based on cyclic azobenzene were synthesized in which a 2,5-dimethoxy, 2,5-dimethyl, 2,5-difluorine or unsubstituted-1,4-dioxybenzene rotating unit and a photoisomerizable 3,3'-dioxyazobenzene moiety are bridged together by fixed bismethylene spacers. Depending

The self-assembled heterocapsule 1.2, which is formed by the hydrogen bonds of tetra(4-pyridyl)-cavitand 1 and tetrakis(4-hydroxyphenyl)-cavitand 2, encapsulates 1 molecule of guests such as 1,4-diacetoxybenzene 3a, 1,4-diacetoxy-2,5-dimethylbenzene 3b, 1,4-diacetoxy-2,5-dialkoxybenzenes (3c,

Reactions of [[MCl2(Cp*)]2] (1: M=Ir, 2: M=Rh) with bidentate ligands (L) such as 1,4-diisocyano-2,5-dimethylbenzene (a), 1,4-diisocyano-2,3,5,6-tetramethylbenzene (b), pyrazine (c) or 4,4'-dipyridyl (d) gave the corresponding dinuclear complexes [[MCl2(Cp*)]2(L)] (M=Ir: 3a, 3b, 5c, 5d; M=Rh: 4b,

OBJECTIVE To study the immunomodulation effect of the recombination Sj16 from Schistosoma japonicum (reSj16) on inflammation response of host. METHODS reSj16 expressed in pGEX-4T-1 was purified by GST purification kit and detected by sodium dodecyl sulfate-polyacrylamide gel electrophoresis

Three internally 1,3-arylene-bridged azacalix[6]aromatics 1-3 were synthesized by the Pd-catalyzed macrocyclic fragment coupling reaction between a stellated dibrominated pentamer and N(2),N(6)-dimethylpyridine-2,6-diamine or N(1),N(3)-dimethylbenzene-1,3-diamine. Single-crystal X-ray analysis

The tissue culture of Saussurea involucrata (TCSauI) KAR. et KIR. was studied to determine its antiinflammatory and analgesic activities in experimental animals. Similar to wild S. involucrata, TCSauI at doses of 75-300 mg/kg i.g. for 7 d markedly inhibited hindpaw edema induced by carrageenin in

The reaction of a double-betaine-containing ligand with LnPMo(12)O(40)·nH(2)O (Ln = Dy, Tb and Er) led to the isolation of new polyoxometalate-templated lanthanide-organic hybrid layers with the molecular formula [Ln(L)(1.5)(H(2)O)(5)][PMo(12)O(40)]·1.5CH(3)CN·2H(2)O (Ln = Dy (1), Tb (2) and Er (3);

Energy-saving separation and purification of industrially important compounds with similar physical and chemical properties by novel molecular crystalline materials are of great importance and highly desired. Here a newly enlarged version of geminiarene, namely elongated-geminiarene (ElGA), is first
