We present a novel application of inductive logic programming (ILP) in the area of quantitative structure-activity relationships (QSARs). The activity we want to predict is the biodegradability of chemical compounds in water. In particular, the target variable is the half-life in water for aerobic aqueous biodegradation. Structural descriptions of chemicals in terms of atoms and bonds are deriv...

ionic liquids such as 1,3-dialkylimidazolium salts make excellent catalysts and solvents for synthesis of dialkyl 2-(dialkoxyphosphoryl)-3-(1-oxo-1-h-phthalazin-2-yl)succinates from 2h-phthalazin-1-one, dialkyl acetylenedicarboxylates, and trialkyl phosphites. under similar conditions, triphenyl phosphite led to dialkyl 2-(diphenoxyphosphoryl)-3-(1-oxo-1-h-phthalazin-2-yl)succinates. the ionic ...

the electrochemical behaviour of lead electrode in hydrochloride solution containing variousoxo-anions at different concentrations was studied by using of cyclic voltammetry (cv) method.results obtained show that the addition of these inorganic compounds decreases the anodic andcathodic currents peaks according to the following order: h2po4- > hpo42-> so42-. it’s revealedalso that the cathodic ...

7,8-Dihydro-8-oxoguanine (8-oxo-G) is a highly abundant and mutagenic lesion. Replicative DNA polymerases (pols) are slowed down at 8-oxo-G and insert both correct cytosine (C) and incorrect adenine (A) opposite 8-oxo-G, but they preferentially extend A:8-oxo-G mispairs. Nevertheless, 8-oxo-G bypass is fairly accurate in vivo. Thus, the question how correct bypass of 8-oxo-G lesions is accompli...

【Introduction】 8-Oxo-2 ́-deoxyguanosine (8-oxo-dG) is a representative nucleoside damage that is formed by oxidation of 2 ́-deoxyguanosine (dG) with reactive oxygen species (ROS), and its presence has been linked to aging, cancer, etc [1]. Unlike dG, 8-oxo-dG forms stable base pairs with both 2 ́-deoxycytidine (dC) and 2 ́-deoxyadenosine (dA). Based on the base-pairing properties of 8-oxo-dG, DNA p...

Synthesis of Substituted 2-[(2-chloro-4-oxo-3-phenylazetidin-1-yl)amino]-1-methyl-6-oxo-4-phenyl-1,6-dihydropyrimidine-5-carbonitrile(6a-r) and 1-methyl-6-oxo-2-[(4-oxo-2-phenyl-1,3-thiazolidin-3-yl)amino]-4-phenyl-1,6-dihydropyrimidine-5-carbonitrile (7a-o)Derivatives was completed using aromatic aldehyde, ethylcyanoacetate thiourea in absolute ethanol as per the standard procedure.The complet...

Nucleic acid oxidation plays an important role in the pathophysiology progress of a variety of diseases. 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxo-dGsn) and 8-oxo-7,8-dihydroguanosine (8-oxo-Gsn), which originate from DNA and RNA oxidation, were the most widely used indicators for oxidative stress. The study investigated the relation between 8-oxo-dGsn, 8-oxo-Gsn, and CKD. 146 patients with CK...

8-Oxo-7,8-dihydroguanine (8-oxo-Gua, also known as 8-hydroxyguanine) is a major base lesion that is generated by reactive oxygen species in both the DNA and nucleotide pool. The role of DNA glycosylases, which initiate base excision repair, in the mutagenic processes of 8-oxo-Gua in DNA and 8-oxo-7,8-dihydro-2'-deoxyguanosine 5'-triphosphate (8-oxo-dGTP, also known as 8-hydroxy-2'-deoxyguanosin...

Neutrophil-derived 5-oxo-6,8,11,14-eicosatetraenoic acid (5-oxo-ETE) is a potent activator of neutrophils and eosinophils. In the present study we examined the biosynthesis and metabolism of this substance by platelets. Although platelets contain an abundant amount of 5-hydroxyeicosanoid dehydrogenase, the enzyme responsible for the formation of 5-oxo-ETE, they synthesize only very small amount...

Dyslipidemia is a major risk factor for development of several obesity-related diseases. The peroxisome proliferator-activated receptor α (PPARα) is a ligand-activated transcription factor that regulates energy metabolism. Previously, we reported that 9-oxo-10,12-octadecadienoic acid (9-oxo-ODA) is presented in fresh tomato fruits and acts as a PPARα agonist. In addition to 9-oxo-ODA, we develo...
