We introduce the localized pair model of electronic structure analysis and propose the two-electron reduced density matrix as an important interpretive tool in chemistry. Interelectronic probability distributions in position and momentum space are calculated for individual localized molecular orbita...

The Vyazovkin model-free method were applied to study non-isothermal degrdn. of an aryl and hetaryl azo dye-contg. polynorbornene using a differential scanning calorimetric (DSC) technique. The samples were heated in nitrogen, with heating rates in the range 5-50 K min-1. The isoconversional method ...

The probability density for the angle between the intracular (u) and extracular (R) coordinate vectors using both Hartree–Fock (HF) and explicitly correlated Kinoshita wave functions is presented. This angular density, A(θRu), and the angular-dependent intex density, X(R,u,θRu), are explored for...

Dimethylplatinum(II) complexes [PtMe2(NN)] {NN = bpy (2,2'-bipyridine), phen (1,10-phenanthroline) or bu2bpy (4,4'-di-tert-butyl-2,2'-bipyridine)} were reacted with alkyl halides (RX = EtI or EtBr, NN = bu2bpy; RX = nBuBr, NN = bpy; RX = CHPh2Br, NN = bpy, phen, or bu2bpy) to yield the Pt(IV) comple...

A small library of semisynthetic analogues of fuscol and eunicol have been prepared and evaluated for in vivo topical anti-inflammatory activity using the mouse-ear edema assay. The first glycosylation of fuscol and eunicol has been achieved using a modified Koenigs-Knorr glycosylation to synthesize...

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. The synthesis of a four-arm organoiron star contg. aryl- and hetaryl-azo chromophores (7) and a cross-linked azo dye-contg. ...

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...

A critical review: the ring-opening polymerization of cyclic esters provides access to an array of biodegradable, bioassimilable and renewable polymeric materials. Building these aliphatic polyester polymers into larger macromolecular frameworks provides further control over polymer characteristics ...

Order of proceedings for the installation ceremony and a biographical sketch of Dr. Abd-El-Aziz.

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

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...

Marine diterpene glycosides (MDGs) respresent a small but highly significant group of the much larger class of marine diterpenes. The three well-studied examples of MDGs are eleutherobins, pseudopterosins and fuscosides, all of which exhibit extremely promising biological activity. The eleutherobins...

Marine invertebrates have proven to be a rich source of secondary metabolites. The growing recognition that marine microorganisms associated with invertebrate hosts are involved in the biosynthesis of secondary metabolites offers new alternatives for the discovery and development of marine natural p...

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...
