  Second-Generation Peptidomimetic Inhibitors of Protein Farnesyltransferase Demonstrating Improved Cellular Potency and Significant in Vivo Efficacy

  摘要：

  The synthesis and evaluation of analogues of previously reported farnesyltransferase inhibitors, pyridyl benzyl ether 3 and pyridylbenzylamine 4, are described. Substitution of 3 at the 5-position of the core aryl ring resulted in inhibitors of equal or less potency against the enzyme and decreased efficacy in a cellular assay against Ras processing by the enzyme. Substitution of 4 at the benzyl nitrogen yielded 26, which showed improved efficacy and potency and yet presented a poor pharmacokinetic profile. Further modification afforded 30, which demonstrated a dramatically improved pharmacokinetic profile. Compounds 26 and 29 demonstrated significant in vivo efficacy in nude mice inoculated with MiaPaCa-2, a human pancreatic tumorderived cell line.

  A single set of reaction conditions for the palladium‐catalyzed amination of a wide variety of (hetero)aryl halides using primary alkyl amines has been developed. By combining the exceptionally high reactivity of the Pd‐PEPPSI‐IPentCl catalyst (PEPPSI=pyridine enhanced precatalyst preparation, stabilization, and initiation) with the soluble and nonaggressive sodium salt of BHT (BHT=2,6‐di‐tert‐butyl‐hydroxytoluene)

  Exogenous photocatalyst-free, single nickel-catalyzed carbon–heteroatom coupling under visible-light irradiation is reported. Over 15 classes of nucleophile can efficiently couple with aryl/alkene halides to afford valuable heteroatomic arenes/alkenes. The unprecedentedly broad substrate scope and late-stage modification of valuable molecules fully demonstrate the benefits of the method.

• Can Palladium Acetate Lose Its “Saltiness”? Catalytic Activities of the Impurities in Palladium Acetate

  Commercially available palladium acetate often contains two major impurities, whose presence can impact the overall catalytic efficacy. This systematic study provides a comparison of the differences in catalytic activity of pure palladium acetate, Pd-3(OAc)(6), with the two impurities: Pd-3(OAc)(6)(NO2) and polymeric [Pd(OAc)(2)](n) in a variety of cross-coupling reactions. The solid state C-13 NMR spectra of all three compounds in conjunction with DFT calculations confirm their reported geometries.
