A new Schiff base has been synthesized from 3-(3-nitrophenyl)-1-phenyl-1H-pyrazole-4carbaldehyde and O-amino phenol. Metal complexes of the Schiff base have been synthesized from acetate salt of Cu (II), Co (II) and Ni (II) metal in the alcoholic medium. The newly prepared Schiff base ligand and metal complexes have been characterized by various physicochemical techniques such as Elemental anal...
The interaction of phenol derivatives with the self-assembled fibrillar network of two different supramolecular gels has been studied. NMR relaxometry reveals the selective interaction of resorcinol over other related molecules with a gel formed by the gelator 2 which contains terminal pyridine units. No selectivity is observed for a related gelator that contains phenyl instead of pyridine moie...
The title compound, [(1-{4-[2-(2,4-di-hydroxy-phen-yl)diazen-1-yl]phen-yl}ethyl-idene)amino]-thio-urea, 1,1,2,2-tetra-chloro-ethane monosolvate, C15H15N5O2S·C2H2Cl4, was prepared from 4-(4-acetyl-phenyl-diazendi-yl)resorcinol and thio-semicarbazide and recrystallized from mixed solvents of tetra-chloro-ethane and n-hexane. 1H NMR and X-ray diffraction data are in support of the thione tautomeri...
4-{[(4-Cyanophenyl)(4H-1,2,4-triazol-4-yl)amino]methyl}phenyl sulfamate and its ortho-halogenated (F, Cl, Br) derivatives are first-generation dual aromatase and sulfatase inhibitors (DASIs). Structure-activity relationship studies were performed on these compounds, and various modifications were made to their structures involving relocation of the halogen atom, introduction of more halogen ato...
Tolumonas auensis Fischer-Romero et al. 1996 is currently the only validly named species of the genus Tolumonas in the family Aeromonadaceae. The strain is of interest because of its ability to produce toluene from phenylalanine and other phenyl precursors, as well as phenol from tyrosine. This is of interest because toluene is normally considered to be a tracer of anthropogenic pollution in la...
A number of cyclopentadienyltitanium aryloxide complexes, 1-Ar-2,3,4,5-Me(4)-Cp(2,6-(i)Pr(2)C(6)H(3)O)TiCl(2) (Ar = 4-Me(3)SiPhenyl (5), 4-(i)PrPhenyl (6), 4-MePhenyl (7), 3,5-(CF(3))(2)Phenyl (8)) and (1-Ar-2,3,4,5-Me(4)CpTiCl(2))(2)(OAr'O) (Ar' = 4,4'-(3,3',5,5'-(i)Pr(4)C(6)H(2)-C(6)H(2)), Ar = 4-SiMe(3)Phenyl (9), 4-MePhenyl (10)) were synthesized from the reaction of a corresponding cyclope...
Vicinally deuterated sec-alkyl phenyl ethers, CH(3)(CH(2))(m)()CH(OPh)CHD(CH(2))(n)()CH(3), display significant differences in mass spectra between threo and erythro stereoisomers. MS/MS experiments, in which parent ions of a single mass are selected and their fragmentation patterns subsequently measured, show that alkene expulsion represents virtually the only decomposition pathway. Two types ...
There are two cation-dianion pairs in the asymmetric unit of the title compound, C(21)H(27)ClN(2)O(3) (2+)·2C(6)H(2)N(3)O(7) (-) {systematic name: 1-[2-(carb-oxy-meth-oxy)eth-yl]-4-[(R)-(4-chloro-phen-yl)phenyl-meth-yl]piperazine-1,4-diium bis-(2,4,6-trinitro-phenol-ate)}. The piperazine group in the levocetirizinium cation is protonated at both N atoms. The acetyl end groups form R(2) (2)(8) h...
L-Phenylalanine inhibition of human alkaline phosphatases with p-nitrophenyl phosphate as substrate.
With p-nitrophenyl phosphate as the substrate, there reportedly is no organ-specific inhibition of alkaline phosphatase (EC 3.1.3.1) activity by L-phenylalanine. However, we found that at pH 10.0, with p-nitrophenyl phosphate as the substrate, L-phenylalanine obviously inhibits the alkaline phosphatase isoenzyme from human placenta, whereas there is little if any inhibition of the isoenzyme fro...
Protein-Tyrosine Phosphatase1B (PTP1B) is a negative regulator of the insulin signaling pathway and is a potential therapeutic target for treatment of type 2 diabetes, cardiovascular disease, metabolic syndrome and cancer. It has been postulated that CNB-001 [4-((1E)-2-(5-(4-hydroxy-3-methoxystyryl-)-1-phenyl-1H-pyrazoyl-3-yl) vinyl)-2-methoxy-phenol)] may regulate PTP1B activity suggested by a...
