Published: August 2011

Conditions for facile solution-phase amide conjugation of amine-modified siRNA with a diverse set of carboxylic acid partners using the coupling reagent HATU are described. These conditions eliminate the need for isolated activated esters and allow for rapid access to conjugates with a wide range of lipophilicity and functionality in good yield.

Phenylboronic acid (PBA) groups are effective in building glucose-responsive drug delivery systems. Chitosan (CS) offers distinct advantages in the construction of PBA-based biomaterials, such as biodegradability and biocompatibility. However, challenges still persist due to the limited solubility of CS.

A rapid and efficient strategy has been developed for the general synthesis of complex peptide aldehydes. N(alpha)-Benzyloxycarbonylamino acids were converted to protected aldehyde building blocks for solid-phase synthesis in four steps and moderate overall yields. The aldehydes were protected as 1,3-dioxolanes except for one case where a dimethyl acetal was used.
