4-(-Phthalimido)phenyl Isonitrile as a Novel Convertible Isocyanide Analogue with the Odorless Property as an Extra Bonus.

We explored a new isonitrile, namely 4-(-phthalimido)phenyl isonitrile, with extraordinary features. The novel isocyanide has a pharmacophore, the phthalimido (Pht) group, that possesses promising pharmaceutical activities. We found that the novel isonitrile is unexpectedly odorless as an extra bonus which makes its handling easy in organic synthesis to serve as a scaffold for building several new amide derivatives through multicomponent reactions, overcoming the stink of common aromatic isonitriles such as phenyl isonitrile, benzyl isonitrile, -nitrophenyl isonitrile, and ethyl 4-isocyano benzoate.

Nature-inspired new isoindole-based Passerini adducts as efficient tumor-selective apoptotic inducers via caspase-3/7 activation.

The development of novel therapeutics promoting selective tumor elimination is the mainstay of clinical oncology. Emerging insights into tumor targeting reveal caspases activation, especially caspase-3, as a personalized anticancer strategy. Our on-going cancer research has exploited Passerini α-acyloxy carboxamides as caspase-3/7-dependent apoptotic inducers.
