host cells. Both antisense technology and smallmolecules have been used to independently inhibit endogenous miR‐122 function, but not in combination. Intracellular stability, efficient delivery, hydrophobicity, and controlled release are some of the current challenges associated with these novel therapeutic methods. Reported herein is the first single‐vehicular system, based on mesoporoussilica nanoparticles

avoiding undesirable solvents which are typically employed for such reactions (e.g.DMF). Under optimised conditions, the synthesis of amides in the presence of both primary and secondary alcohol functions was achieved in high to excellent yields (65–94%). Overall, the methods described have significant practical advantages over conventional approaches based upon bulk solvents including greater yields

The present invention is a method for identifying agents which modulate microRNA activity. The invention involves contacting a cell harboring a microRNA and a microRNA binding sequence, which is operably linked to a nucleic acid molecule encoding a reporter protein, with a test agent and determining whether the test agent increases or decreases the expression of the reporter protein thereby identifying a microRNA modulator. Antagonists identified by this screening assay are provided, as are methods for using the same to inhibit microRNA activity and prevent or treat disease.
