Apoptosis is generally believed to be a process that requires several hours, in contrast to non-programmed forms of cell death that can occur in minutes. Our findings challenge the time-consuming nature of apoptosis. We describe herein the discovery and characterization of a small molecule, named Raptinal, which initiates intrinsic pathway caspase-dependent apoptosis within minutes, in multiple different cell lines. Comparison to a mechanistically diverse panel of apoptotic stimuli reveals Raptinal-induced apoptosis proceeds with unparalleled speed. The rapid phenotype enabled identification of the critical roles of mitochondrial voltage-dependent anion channel function, mitochondrial membrane potential/coupled respiration, and mitochondrial complex I, III and IV function for apoptosis induction. Use of Raptinal in whole organisms demonstrates its utility to study apoptosis in vivo for a variety of applications. Overall, rapid inducers of apoptosis are powerful tools that will be used in a variety of settings to generate further insight into the apoptotic machinery.

A novel and tunable α-hydroxylation/α-chlorination of benzyl ketone derivatives has been developed for the construction of hetero-quaternary carbon centers by iron(III) chloride hexahydrate mediated selective transformations through the application of different oxidants, especially the crystal water in the catalyst as an OH source is firstly reported in this hydroxylation.
