K2S2O8 promoted decarboxylativealkynylation of α-ketoacids and oxamic acids has been developed. This process features mild reaction conditions, a broad substrate scope, and good functional-group tolerance, therefore providing a new and efficient access to a wide range of ynones and propiolamides. Furthermore, this radical process could also be successfully applied to alkynylation of the Csp2–H bond
已经开发出温和的K 2 S 2 O 8促进α-酮酸和草酰胺酸的脱羧炔基化。该工艺具有温和的反应条件,广泛的底物范围和良好的官能团耐受性,因此提供了一种新型且有效的途径,可广泛使用炔酮和丙酰胺类化合物。此外,该自由基过程也可以成功地用于高价炔碘试剂对DMF中C sp 2 -H键的炔基化反应。

A series of oxamyl dipeptides were optimized for pan caspase inhibition, anti-apoptotic cellular activity and in vivo efficacy. This structure-activity relationship study focused on the P4 oxamides and warhead moieties. Primarily on the basis of in vitro data, inhibitors were selected for study in a murine model of alpha-Fas-induced liver injury. IDN-6556 (1) was further profiled in additional in vivo
The present invention provides compounds for modulating protein kinase enzymatic activity for modulating cellular activities such as proliferation, differentiation, programmed cell death, migration and chemoinvasion. More specifically, the invention provides quinazolines and quinolines which inhibit, regulate, and/or modulate kinase receptor, particularly c-Met, KDF, c-Kit, flt-3 and flt-4, signal transduction pathways related to the changes in cellular activities as mentioned above, compositions which contain these compounds, and methods of using them to treat kinase-dependent diseases and conditions. The present invention also provides methods for making compounds as mentioned above, and compositions which contain these compounds.
