Goldansaz, Seyed Ali published the artcilePredictive blood biomarkers of sheep pregnancy and litter size, SDS of cas: 63-68-3, the publication is Scientific Reports (2022), 12(1), 10307, database is CAplus and MEDLINE.

Early detection of sheep pregnancy and the prediction of how many lambs a pregnant ewe delivers affects sheep farmers in a number of ways, most notably with regard to feed management, lambing rate, and sheep/lamb health. The standard practice for direct detection of sheep pregnancy and litter size (PLS) is ultrasonog. However, this approach has a number of limitations. Indirect measurement of PLS using blood biomarkers could offer a simpler, faster and earlier route to PLS detection. Therefore, we undertook a large-scale metabolomics study to identify and validate predictive serum biomarkers of sheep PLS. We conducted a longitudinal experiment that analyzed 131 serum samples over five timepoints (from seven days pre-conception to 70 days post-conception) from six com. flocks in Alberta and Ontario, Canada. Using LC-MS/MS and NMR, we identified and quantified 107 metabolites in each sample. We also identified three panels of serum metabolite biomarkers that can predict ewe PLS as early as 50 days after breeding. These biomarkers were then validated in sep. flocks consisting of 243 animals yielding areas-under-the-receiver-operating-characteristic-curve (AU-ROC) of 0.81-0.93. The identified biomarkers could lead to the development of a simple, low-cost blood test to measure PLS at an early stage of pregnancy, which could help optimize reproductive management on sheep farms.

Levene, P. A. published the artcileConfigurational relationships of acids of the phenethyl series to those of the normal series, HPLC of Formula: 1949-41-3, the publication is Journal of Biological Chemistry (1935), 311-21, database is CAplus.

Substances of the type Ph(CH₂)_m.CHMe(CH₂)_nCO₂H offer an opportunity to study the effect of the distance of the CO₂H group from the asym. center when the distance of the Ph group is kept constant or varied. d-Ph(CH₂)₂CHMeCO₂H has been configurationally correlated with l-Ph(CH₂)₂CHMeEt. Configurationally related 2-octyl- and 2-phenethylpropionic acids rotate polarized light in the same direction and, when m is 2, substitution of a hexyl by a Ph group does not change the direction of rotation of the EtCO₂H substituted in position 2. In the phenethyl series change from n = 0 to n = 1 brings about the same change in the direction of rotation as in the octyl series. Exhaustive hydrogenation of the phenethyl group has no effect on the direction of rotation except in the case of Ph(CH₂)₂CHMe(CH₂)₂Br in which the direction is reversed in the hexahydro derivative The following compounds were prepared by methods given in the preceding abstract All rotations are for the homogeneous substances. l-Ph(CH₂)₂CHMeCO₂H, b₂ 155¡ã, d₄³² 1.042, [M]_D³² -48.3¡ã, by CH₂(CO₂Et)₂ synthesis and resolved by the cinchonidine salt; d-Et ester, b₂ 120¡ã, d₄²⁸ 0.979, [M]_D²⁸ 7.6¡ã; l-Ph(CH₂)₂CHMeCH₂OH, b₁₇, 157¡ã, d₄²⁸ 0.968, [M]_D²⁸ -2.7¡ã; l-Ph(CH₂)₂CHMeCH₂Br, b₁₇ 151¡ã, d₄²⁷ 1.235, [M]_D²⁷ -5.8¡ã; l-Ph(CH₂)₂CHMeCH₂CO₂H, b₂ 162¡ã, d₄²⁷, 1.033, [M]_D²⁷ -6.04¡ã; l-Et ester, b₂ 131¡ã, d₄²⁷ 0.973, [M]_D²⁷ -4.9¡ã; l-Ph(CH₂)₂CHMe(CH₂)₂OH, b₁₇, 157¡ã, d₄²⁷ 0.959, [M]_D²⁷; -3.99¡ã; l-Ph(CH₂)₂CHMe(CH₂)₂Br, b₁₇ 160¡ã, d₄²⁷ 1.201, [M]_D²⁷ -2.29¡ã; l-Ph(CH₂)₂CHMeEt, b₁₅ 112¡ã, d₄²⁵ 0.855, [M]_D²⁷ -4.76¡ã; d-C₆H₁₁CH₂)₂CHMeCO₂H, b₂ 156¡ã, d₄²⁷ 0.968, [M]_D²⁷ 3.4¡ã; d-Et ester, b₁ 101¡ã d₄²⁸ 0.919, [M]_D²⁸ 4.92¡ã; l-C₆H₁₁(CH₂)₂CHMeCH₂OH, b₁₇ 141¡ã, d₄²⁷ 0.898, [M]_D²⁷ -2.09¡ã; C₆H₁₁(CH₂)₂CHMeCH₂Br, b₁₅ 142¡ã, [M] 0¡ã. l-C₆H₁₁(CH₂)₂CHMeCH₂CO₂H, b₂ 158¡ã, d₄²⁷ 0.959, [M]_D²⁷ -2.36¡ã; l-Et ester, b₁₇ 162¡ã, d₄²⁵ 0.918, [M]_D²⁵ -1.85¡ã; l-C₆H₁₁(CH₂)₂CHMe(CH₂)₂OH, b₁₇ 157¡ã, d₄²⁷ 0.893, [M]₄²⁷ -1.84¡ã; d-C₆H₁₁(CH₂)₂ CHMe(CH₂)₂Br, b₁₅ 151¡ã, d₄²⁷ 1.122, [M]₄²⁷ 1.12¡ã; l-C₆H₁₁(CH₂)₂CHMeEt, b₁₅ 110¡ã, d₄²⁷ 0.806, [M]_D²⁷ -2.82¡ã.

Levene, P. A. published the artcileMaximum rotations of configurationally related carboxylic acids containing a phenyl or a cyclohexyl group, Computed Properties of 1949-41-3, the publication is Journal of Biological Chemistry (1935), 329-42, database is CAplus.

Maximum rotations of acids of the types RPhCH(CH₂)_nCO₂H (Type I), RC₆H₁₁CH(CH₂)_nCO₂H (Type II) and RMeCH(CH₂)_nCO₂H (Type III) are discussed for cases where n varies from 0 to 3. With compounds of Type I the direction of rotation shifts to the left on passing from n = 0 to 1, to the right from n = 1 to 2, to the left from n = 2 to 3. This shift also holds in the cases of the esters, carbinols and halides. In acids of Type III the CO₂H group when n = 0 owes its activity to a band located further in the ultraviolet than the Ist band of the CO₂H group which is responsible for the activity of the CO₂H groups of the acids when n = 1. On passing from the acids to esters when n is constant the shift is to the left in the disubstituted acetic, to the right in the propionic, to the left in the butyric: and to the right in the valeric acids. This type of acid therefore does not follow Freudenberg’s rule of shift. By the use of methods given in the preceding abstracts the following compounds were prepared All values for [M]_D are maximum and for the homogeneous substances.

In addition, the previously reported [Co(tpen)](ClO₄)₃ [tpen = N,N,N‘,N‘-tetrakis(2-pyridylmethyl)ethylenediamine], [Co(tptn)](ClO₄)₃ [tptn = N,N,N‘,N‘-tetrakis(2-pyridylmethyl)-1,3-propanediamine], and ¦¤¦«¦¤-(-)₅₈₉-[Co(tppn)](ClO₄)₃ [tppn = N,N,N‘,N‘-tetrakis(2-pyridylmethyl)-1,2-propanediamine] were prepared and characterized by high-resolution ¹H NMR spectroscopy for the 1st time. Two-dimensional ¹H NMR spectroscopy was utilized to complete the pyridine H assignments in the 1-dimensional ¹H NMR spectra of the tpen and tptn complexes. The 300-MHz ¹H NMR spectra of all of these complexes show good resolution for all of the hydrogens. The AB patterns of the pyridyl hydrogens and ethylenediamine hydrogens are discussed and correlated to 1 another. The AB coupling constants of the pyridyl rings are ?16 and 20 Hz for the G (in the plane of the ethylenediamine ring) and R (out of the plane of the ethylenediamine ring) chelate rings, resp.; these results are consistent with the well-documented AB coupling constants of (amino polycarboxylato)cobalt complexes. All of the ¹H NMR spectra were interpreted completely, and the usefulness of using AB coupling constants to assign individual AB patterns to R, G, or E chelate rings in polypyridyl complexes is demonstrated. In addition, the partial resolution of [Co(tpen)](ClO₄)₃ is reported, and the visible spectra of all of the complexes are reported.

Moosus, M. published the artcileQuantitative structure-activity relationship analysis of acute toxicity of diverse chemicals to Daphnia magna with whole molecule descriptors, COA of Formula: C3H8N2S, the publication is SAR and QSAR in Environmental Research (2011), 22(7-8), 757-774, database is CAplus and MEDLINE.

Quant. structure-activity relationship anal. and estimation of toxicol. effects at lower-mid trophic levels provide first aid means to understand the toxicity of chems. Daphnia magna serves as a good starting point for such toxicity studies and is also recognized for regulatory use in estimating the risk of chems. The ECOTOX database was queried and analyzed for available data and a homogeneous subset of 253 compounds for the endpoint LC50 48 h was established. A four-parameter quant. structure-activity relationship was derived (coefficient of determination, r² = 0.740) for half of the compounds and internally validated (leave-one-out cross-validated coefficient of determination, r²_cv = 0.714; leave-many-out coefficient of determination, r²_LMO = 0.738). External validation was carried out with the remaining half of the compounds (coefficient of determination for external validation, r²_ext = 0.634). Two of the descriptors in the model (log P, average bonding information content) capture the structural characteristics describing penetration through bio-membranes. Another two descriptors (energy of HOMO, weighted partial neg. surface area) capture the electronic structural characteristics describing the interaction between the chem. and its hypothetic target in the cell. The applicability domain was subsequently analyzed and discussed.

Hua, Xuewen published the artcileNovel Anthranilic Diamide Insecticides: Design, Synthesis, and Insecticidal Evaluation, Quality Control of 6950-53-4, the publication is Australian Journal of Chemistry (2014), 67(10), 1491-1503, database is CAplus.

Three series of new anthranilic diamide derivatives containing sulfide, N-cyanomethylsulfilimine, and N-cyanomethylsulfoximine groups were designed and synthesized by coupling the active substructures of anthranilic diamides and sulfoxaflor. The structures of the synthesized compounds were confirmed by IR spectroscopy, ¹H and ¹³C NMR, and elemental anal. Several unique structural characteristics were revealed via the crystal structure anal. of compound N-(2-(2-methyl-2-(methylthio)propylcarbamoyl)-4-chloro-6-methylphenyl)-3-bromo-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-carboxamide I. Bioassay results indicated that most of the synthesized compounds showed superior insecticidal activities against Mythimna separata and Plutella xylostella when compared with the pos. control cyantraniliprole. In particular, N-(2-(2-methyl-2-(N-cyanomethylsulfideimino)propylcarbamoyl)-4-chloro-6-methylphenyl)-3-bromo-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-carboxamide II showed excellent insecticidal activity against Mythimna separata, with a mortality rate of 100% at a concentration of 1¦Ìg?mL^-1. These results indicated that sulfide, N-cyanomethylsulfilimine, and N-cyanomethylsulfoximine moieties, as important active substructures, could improve or maintain the activity of the anthranilic diamide and promote novel pesticide development.

A transition metal free oxidative C-H bond functionalization/esterification of ¦Á-alkoxy alkanes with acids is described. This method is effectively mediated by NCS instead of traditional oxidants, like TBHP or its derivatives, and directly generates the esterification products in moderate to high yield under mild conditions. This tranformation constitutes a practical and general approach toward various ¦Á-acyloxy ethers with broad substrate generality; alkyl-, aryl-, alkenyl- and alkynyl-carboxylic acids are all well tolerated.
