Mitochondrial dysfunction has been associated with several human pathological conditions, including cancer, aging, and neurodegenerative diseases. Thus, the availability of selective fluorescent probes for mitochondria could play an important role in the future for monitoring cellular functions and disease progression. In this work, we have studied how the photophysical properties and subcellular accumulation of nonconventional coumarin-based COUPY fluorophores can be fine-tuned through replacement of the para-pyridinium moiety with several heterocycles. Among them, ortho,para-pyrimidinium substitution provided novel fluorophores with suitable photophysical properties for bioimaging applications, including emission in the far-red to NIR region, large Stokes' shifts, and high photostability. Furthermore, the compounds exhibited excellent cell membrane permeability in living cells and a higher selectivity for mitochondria compared with the parent COUPY fluorophores. Overall, these results provided useful insights into the development of novel mitochondria-targeted fluorescent probes based on small organic molecules, since higher selectivity for this organelle can be achieved through the replacement of conventional N-alkylated pyridinium moieties by the corresponding N-alkylated-ortho,para-pyrimidinium counterparts.

Inhibitors of p38 mitogen-activated protein (MAP) kinase, which are closely involved in the production of inflammatory cytokines, are considered promising curative drugs for chronic inflammatory disorders. However, there is also a growing concern regarding its systemic side effects. To reduce the occurrence of side effects, we have identified a novel p38 MAP kinase inhibitor that shows properties of an antedrug, which imparts its effect solely on the inflammatory site and is metabolically inactivated right after. We have designed isoxazole derivatives through the addition of a fresh interacting fourth site to the structure of the prototypical p38 MAP kinase inhibitor that harbors three point interactive sites. The derivative 26d (AKP-001) shows excellent p38 MAP kinase inhibitory activity and a high selectivity for various kinases. Its rapid metabolism has been confirmed in rats. Moreover, 26d has been shown to be effective in animal models of inflammatory bowel disease.
