Aims: Total twenty-nine [1,2,4]triazolo[4,3-a]pyrazine derivatives were designed and synthesized. Method: The target compounds, especially 4aa, showed potent activity to inhibit c-Met both in an enzyme assay and a cellular assay. The comprehensive screening for the inhibition of 60 different kinases revealed that 4aa could selectively inhibit c-Met while had no effect on other kinases, indicating 4aa is an excellent c-Met selective inhibitor. Result: The flow cytometry studies found that 4aa had a similar behavior to the positive control SGX-523 in terms of causing the tumor cell apoptosis and blocking cell-cycle progression. More importantly, 4aa showed much better pharmacokinetic properties than SGX-523. Altogether, the findings suggested the target compounds may be potential anti-tumor drug candidates.

A mild and effective method is described for 11C-labeling of peptides selectively at the N-terminal nitrogen or at internal lysine positions. The presented method relies on the use of specific biphosphine palladium?methyl complexes and their high reactivity towards amino-carbonylation of amine groups in the presence [11C]carbon monoxide. The protocol facilitates the production of native N-11C-acetylated peptides, without any structural modifications and has been applied to a selection of bioactive peptides.

The incorporation of CO2 into organometallic and organic molecules represents a sustainable way to prepare carboxylates. The mechanism of reductive carboxylation of alkyl halides has been proposed to proceed through the reduction of NiII to NiI by either Zn or Mn, followed by CO2 insertion into NiI-alkyl species. No experimental evidence has been previously established to support the two proposed steps. Demonstrated herein is that the direct reduction of (tBu-Xantphos)NiIIBr2 by Zn affords NiI species. (tBu-Xantphos)NiI-Me and (tBu-Xantphos)NiI-Et complexes undergo fast insertion of CO2 at 22 C. The substantially faster rate, relative to that of NiII complexes, serves as the long-sought-after experimental support for the proposed mechanisms of Ni-catalyzed carboxylation reactions.

Tuning the reactivity of arylpalladium intermediates enables control of catalytic arylative 5-exo and 6-endo cyclizations of alkynols. The two modes of cyclizations represent a rare example of controllable, regioselective difunctionalization of alkynes. The cyclizations are useful in offering a divergent synthesis of oxygen-containing heterocycles, which is of synthetic use for further derivatization. Formal synthesis of an hNK-1 receptor antagonist also showcases the utility of our arylative cyclization.
