Synthesis of Allylsilanes via Nickel-Catalyzed Cross-Coupling of Silicon Nucleophiles with Allyl Alcohols

NiCl2(PMe3)2-catalyzed reaction of allyl alcohols with silylzinc reagents, including PhMe2SiZnCl, Ph2MeSiZnCl, and Ph3SiZnCl, was performed, achieving allylsilanes in high yields. Aryl- and heteroaryl-substituted allyl alcohols, (E)-3-arylprop-2-en-1-ols, 1-aryl-prop-2-en-1-ols, and (E)-1-phenylpent-1-en-3-ol can be employed in the transformation. A range of functional groups as well as heteroaryl groups were tolerated. Reaction exhibited high regioselectivity and E/Z-selectivity when 1- or 3-aryl-substituted allyl alcohols were used as the substrates. Reaction of chiral allyl alcohol, (S,E)-1-phenylpent-1-en-3-ol, yielded a configuration-inversion product (R,E)-dimethyl(phenyl)(1-phenylpent-1-en-3-yl)silane.

The discovery of MK-4256, a potent SSTR3 antagonist as a potential treatment of type 2 diabetes

A structure-activity relationship study of the imidazolyl-beta- tetrahydrocarboline series identified MK-4256 as a potent, selective SSTR3 antagonist, which demonstrated superior efficacy in a mouse oGTT model. MK-4256 reduced glucose excursion in a dose-dependent fashion with maximal efficacy achieved at doses as low as 0.03 mg/kg po. As compared with glipizide, MK-4256 showed a minimal hypoglycemia risk in mice.

Identification and characterisation of odorants in a squishy toy using gas chromatography-mass spectrometry/olfactometry after thermal extraction

Soft, squashable toys known as squishies have become increasingly popular amongst children. In this study, one such toy was evaluated sensorially by a trained panel and analytically using gas chromatography-mass spectrometry/olfactometry (GC-MS/O) after thermal extraction of the sample. Sensory analysis revealed the presence of an intense and unpleasant odour exhibited by the sample. The smell was dominated by almond- and inflatable swimming aid-like, as well as malty and glue-like notes, but also pleasant odours that were described as caramel-like and coconut-like. GC-MS/O analysis identified 2-butoxyethanol, cyclohexanone, gamma-nonalactone, and ethyl maltol as being the main causative substances for the overall odour of the product. The data additionally indicated that the pleasant smelling substances gamma-nonalactone (coconut-like smell) and ethyl maltol (caramel-like smell) were intentionally added by the manufacturer to mask the unpleasant odour of the solvents.

Optimisation of ITK inhibitors through successive iterative design cycles

Based on a hit cluster of compounds inhibiting interleukin-2 inducible T-cell kinase (ITK) in the submicromolar range a series of ITK inhibitor libraries were synthesized. Through iterative design cycles including kinase crystal structure information, indolylindazole libraries were identified which showed low nanomolar activity in enzymatic and cellular assays. The potential of these novel lead series was confirmed through in vivo tests in an anti-CD3-IL2 mouse model. The intravenous administration of highly potent ITK inhibitor 11o resulted in dose-dependent, efficient suppression of IL-2.
