Polyethers and/or thioethers contg. organoiron moities in either the backbone or the side chain were prepd. under mild reaction conditions. Polysiloxanes contg. arene cyclopentadienyliron or ferrocene moieties were also prepd. and their morphol. thermal and spectroscopic characterizations were examd...

The introduction of metallic moieties coordinated to arenes resulted in polyethers or polyether/thioethers, which have excellent thermal properties. A no. of new cationic organoiron- and ferrocene-contg. linear and crosslinked polymers was achieved successfully via acid-catalyzed condensation polymn...

Various four-arm organoiron macromols. contg. different azo dye moieties have been prepd. via metal-mediated nucleophilic arom. substitutions and ester condensation reactions.

Stability-indicative detn. of bambuterol hydrochloride (BH) in the presence of its degrdn. product (terbutaline), which is also the metabolite, is investigated. The degrdn. product was isolated, via acid-degrdn., characterized and elucidated. Selective quantification of BH, singly in bulk form, phar...

The kinetics involved in the thermal degrdn. of an aryl azo dye-contg. polynorbornene was investigated by using isothermal DSC data. The activation energy of the degrdn. was found to be temp. dependent with two different values of 140±5 and 21±2 kJ mol-1, and the Avrami exponent was obsd. to i...

Pyrazole derivs. are well documented to possess anti-inflammatory activity but their effects on microglial activation are unknown. We detd. the efficacy of the novel pyrazole compd. 2-MBAPA (R/S-(±)-2-Methylbenzylamino 2-oxo-N-[4-cyano-1-phenyl-1H-pyrazol-5-yl] acetamide) on activated microglia u...

In the title compd., [Fe(C13H11O2)2], there are markedly different orientations of the two phenylmethoxycarbonyl substituents [O-C-C-C torsion angles = 84.5(3) and 139.6(2)°]. These orientations are mediated by a no. of intermol. C-H···O interactions, which result in a one-dimensional hy...

Utilizing organoiron-mediated nucleophilic arom. substitution, a no. of allylamine-contg. organoiron complexes were prepd. Amide formation between 1,1'-ferrocene dicarbonyl chloride and allylamine produced a similar ferrocene compd. These materials were subjected to hydrosilation with methyldiethoxy...

The electrochem. behavior of cyclcopentadienyliron contg. complexes and polymers has given rise to useful materials, such as electrochem. probes for biol. systems, electrocatalysts, and electrochem. switches.The development of new systems contg. cyclopentadienyliron complexes can only improve and in...

The aim of the present study is to det. the activities of three kinds of antibiotics against Staphylococcal biofilm and planktonic cultures in vitro, and to indicate the enhancement of biofilm formation in response to stress factors such as glucose and sub-inhibitory concns. of antibiotics by using ...

A modified synthesis of 25-allyl-26,27,28-trihydroxycalix[4]arene is reported. This calix[4]arene was utilized to prep. calix[4]arenes contg. norbornene and calix[4]arene contg. azo dyes and norbornene on their upper rims. The calixarene monomers were reacted with Grubbs' second generation cata...

The versatility of cationic cyclopentadienyliron complexes is demonstrated for the generation of calix[4]arene-based dendrimers and polymers. Dendrimers were prepd. from a branched organoiron calix[4]arene through subsequent reactions of azo dyes and organoiron complexes. The resulting azo dye-contg...
