A comparative study of the effects of biphenyl and Kanechlor-400 (KC-400) on the respiratory and energy linked activities of rat liver mitochondria was made, and some differences in effects caused by the chlorination of biphenyl were clarified. The inhibition of state 3 respiration with succinate by biphenyl was less than that observed with alpha-ketoglutarate/malate. By contrast, KC-400 exhibi...
MCM-41@L-Arg@Pd(0) has been prepared by some consequence reactions. This nano structural material has been characterized via different technique including: XRD, TGA, BET, EDS, X-Ray maps, SEM, ICP-OES and FT-IR analysis. The synthesis of a variety of biphenyl compounds has been achieved successfully via a reaction of aryl halides with arylboronic acids in the presence of this nanostructure (MCM...
These findings could be interpreted as implying that the enhancement by carcinogens in vitro of hamster hepatic microsomal biphenyl 2-hydroxylase (McPherson ‘et al., 19746) is mediated through an effect on the microsomal membrane rather than via direct specific conformational modification of the biphenyl 2-hydroxylase enzyme itself. In an attempt to differentiate between the soluble and microso...
We report the preparation and characterization of 4′-([1,1′-biphenyl]-4-yl)-3,2′:6′,3″-terpyridine (1), 4′-(4′-fluoro-[1,1′-biphenyl]-4-yl)-3,2′:6′,3″-terpyridine (2), 4′-(4′-chloro-[1,1′-biphenyl]-4-yl)-3,2′:6′,3″-terpyridine (3), 4′-(4′-bromo-[1,1′-biphenyl]-4-yl)-3,2′:6′,3″-terpyridine (4), 4′-(4′-methyl-[1,1′-biphenyl]-4-yl)-3,2′:6′,3″-terpyridine (5), their reactions with copper(II) acetat...
a series of n-substituted-2,4-thiazolidinedione derivatives (tzds) were prepared via n-alkylation of 2,4-tzd at position 3 using substituted benzyl halides. synthesized n-substituted-2,4-tzd was then substituted at position 5 with substituted aromatic aldehyde according to knoevenagel condensation method. structures of the compounds were elucidated using various spectral techniques viz. ir, 1hn...
Pseudomonas toyotomiensis KF710 utilizes biphenyl and degrades polychlorinated biphenyls (PCBs). Here, we report the genome sequence of the KF710 strain, consisting of 5,596,721 bp with 5,155 coding sequences. The biphenyl catabolic genes were almost identical to those of Pseudomonas pseudoalcaligenes KF707, one of the most well-characterized biphenyl-utilizing strains.
Iodine adds across both triple bonds of 4,4'-bis-(prop-2-yn--yl-oxy)biphenyl, yielding the 4,4'-bis-(2,3-diiodo-all-yloxy)biphenyl title compound, C(18)H(14)I(4)O(2); the 2,3-diiodo-ally-oxy substituents have the I atoms in an E configuration. In the biphenyl portion of the mol-ecule, the aromatic rings are inclined by 37.8 (2)°.
A series of N-{(substituted)1,3-benzothiazol-2-yl}-1,1 '-biphenyl-4-carboxamides was synthesized by reaction between biphenyl acid chloride and 2-aminobenzothiazole. The synthesized compounds were screened in vivo for diuretic activity. Among the series, N-(1,3-benzothiazol-2-yl)-1,1'-biphenyl-4-carboxamide (II) was found to be the most promising candidate.
NHC-Pd-PEPPSI-catalyzed α-alkylation of ketones with primary alcohols and tandem Suzuki–Miyaura-coupling/α-alkylation reactions under borrowing hydrogen conditions were reported.
