The present invention is directed compositions for delivery of RNA interference (RNAi) triggers to integrin positive tumor cells in vivo. The compositions comprise RGD ligand- targeted amphipathic membrane active polyamines reversibly modified with enzyme cleavable dipeptide-amidobenzyl-carbonate masking agents. Modification masks membrane activity of the polymer while reversibility provides physiological responsiveness. The reversibly modified polyamines (dynamic polyconjugate or conjugate) are further covalently linked to an RNAi trigger.

so far hampered pharmacological target validation and clinical drug development. Herein, we report, for the first time, the discovery of a series of 5‐(2‐(phenylamino)pyrimidin‐4‐yl)thiazole‐2(3H)‐onederivatives as Mnk inhibitors. Several derivatives demonstrate very potent Mnk2 inhibitory activity. The most active and selective compounds were tested against a panel of cancer cell lines, and the results

Provided herein are novel heteroaryl compounds, compositions comprising the compounds, and methods of treatment or prevention comprising administration of the compounds. The compounds are effective in the targeting of cells defective in the von Hippel-Lindau gene and in inducing autophagic cell death. The methods are directed to treating or preventing diseases such as cancer, and in particular cancers resulting from von Hippel-Lindau disease. The compounds of the invention may be administered in combination with another therapeutic agent.
