Liu, Lei published the artcileSeveral non-salt and solid thienopyridine derivatives as oral P2Y12 receptor inhibitors with good stability, Synthetic Route of 32345-60-1, the main research area is thienopyridine preparation purinoceptor receptor inhibitor; Clopidogrel resistance; Hygroscopicity; P2Y(12) receptor inhibitors; Prodrug design; Stability; Thienopyridine derivatives.

A series of novel thienopyridine derivatives I (R1 = H, Me; R2 = H, Et, Me, 4-mthoxyphenyl, etc.; R3 = H, Me, Ph) was designed and synthesized as P2Y12 receptor inhibitors. Several solid compounds were assessed for inhibitory effect where they exhibited stronger potency than clopidogrel. Compound I (R1 = R3 = H, R2 = Me (II); R1 = R3 = H, R2 = prop-1-en-1-yl) were evaluated for metabolism to verify that they could overcome clopidogrel resistance and for toxicity where they showed lower toxicity than prasugrel. Compound II exhibited lower risk of bleeding than prasugrel and showed good stability under stress testing. Overall, as a promising antiplatelet agent, representative compound II showed the following advantages: (1) no drug resistance for CYP2C19 poor metabolizers; (2) higher potency than clopidogrel; (3) lower toxicity than prasugrel; (4) lower risk of bleeding than prasugrel; and (5) good stability as a non-salt solid.

Kar, S. published the artcileQSAR with quantum topological molecular similarity indices: toxicity of aromatic aldehydes to Tetrahymena pyriformis, Application In Synthesis of 286474-59-7, the main research area is aromatic aldehyde toxicity Tetrahymena pyriformis QSAR quantum topol mol; QTMS descriptors aromatic aldehyde toxicity Tetrahymena pyriformis; QSPR aromatic aldehyde toxicity Tetrahymena pyriformis; genetic partial least square model predictive capacity toxicity Tetrahymena; lipid water partition coefficient predictor variable toxicity Tetrahymena pyriformis.

Extensive production and use of aromatic aldehydes and their derivatives without proper certification is alarming with regard to environmental safety. This concern motivated the construction of predictive quant. structure-activity relation (QSAR) models for the toxicity of aldehydes to the ecol. important species Tetrahymena pyriformis. Quantum topol. mol. similarity (QTMS) descriptors, along with the lipid-H2O partition coefficient (log Ko/w), were used as predictor variables. The QTMS descriptors were calculated at different levels of theory including AM1, HF/3-21G(d), HF/6-31G(d), B3LYP/6-31 + G(d,p), B3LYP/6-311 + G(2d,p) and MP2/6-311+G(2d,p). The data set of 77 aromatic aldehydes was divided into a training set (n = 58) and a test (n = 19) set, and 58 models were developed using partial least squares (PLS) and genetic partial least squares (G/PLS). The authors evaluated the overall predictive capacity of the models based on leave-one-out predictions for the training set compounds and model derived predictions for the test set compounds For both PLS and G/PLS, the models built at the HF/6-31G(d) level show better predictivity (based on overall prediction) than the models developed at any of the other 5 levels. Further validation was also performed using (process and model) randomization tests. Improved predictive QSAR models for aldehydic toxicity to Tetrahymena pyriformis can be generated using QTMS descriptors along with log Ko/w.

A form independent activation of zinc, concomitant generation of organozinc species and engagement in a Negishi cross-coupling reaction via mechanochem. methods is reported. The reported method exhibits a broad substrate scope for both C(sp3)-C(sp2) and C(sp2)-C(sp2) couplings and is tolerant to many important functional groups. The method may offer broad reaching opportunities for the in situ generation organometallic compounds from base metals and their concomitant engagement in synthetic reactions via mechanochem. methods.

Purohit, Priyank published the artcileC-O Bond Activation by Nickel-Palladium Hetero-Bimetallic Nanoparticles for Suzuki-Miyaura Reaction of Bioactive Heterocycle-Tethered Sterically Hindered Aryl Carbonates, SDS of cas: 480438-56-0, the main research area is aryl carbonate arylboronic acid Ni Pd binary Suzuki Miyaura; biaryl heterocycle tethered preparation.

Ni-Pd binary nanoclusters are reported for the activation of the C-O bond for Suzuki-Miyaura cross-coupling of bioactive heterocycle-tethered sterically hindered aryl carbonates with aryl boronic acids. The reaction does not take place in the presence of either the Pd or Ni salts/complexes or the individual Pd or Ni nanoparticles, indicating ensembling cooperativity between the Pd and Ni nanoparticles in activating the C-O bond.

Zhang, Jilei published the artcileLigand-free copper-catalyzed coupling of nitroarenes with arylboronic acids, Name: 4-(4-Chlorophenoxy)benzaldehyde, the main research area is ligand free copper catalyzed coupling nitro arene arylboronic acid.

The first example of copper-catalyzed coupling of nitro arenes with arylboronic acids was developed, providing diaryl ethers in moderate to excellent yields. The efficiency of this reaction was demonstrated by compatibility with a wide range of groups. Moreover, the rigorous exclusion of air/moisture is not required in these transformations. Thus, the method represents a simple and facile procedure to access diaryl ethers. Preliminary mechanistic experiments using deuterium labeling showed that the oxygen atom was derived from water.
