The invention provides pharmaceutical compositions and method of using the compositions, wherein the compositions comprise liposomes or micelles that contain one or more targeting peptides and/or anticancer drugs. In various embodiments, the components of the liposomes can include a) a phospholipid and optionally a lipid that is not a phospholipid; b) a pegylated lipid; c) a peptide-ethylene glycol (EG)-lipid conjugate wherein the peptide is a targeting ligand, and d) one or more drug-conjugated lipid, encapsulated drugs, or a combination thereof. The peptide-EG-lipid conjugate can be, for example, a compound of Formula (I) or Formula (II). The ethylene glycol (EG) segments of the peptide-EG-lipid conjugate can be, for example, EG6 to about EG36; and the EG segment can be conjugated to one or more lysine moieties.

Developing protein tyrosine phosphatase-1B (PTP1B) inhibitors is an important strategy to treat type 2 diabetes mellitus (T2DM). Most existing ionic PTP1B inhibitors aren't of clinical useful due to their low cell-permeability, however. Herein, we introduced a series of lipid-like acid-based (salicylic acid) modules to prepare PTP1B inhibitors, and demonstrated a marked improvement of cell-permeability while maintaining excellent PTP1B inhibitory activity (e.g. compound B12D, IC50= 0.37 mu M against PTP1B and P-app = 1.5x10(-6) cm/s). We believe that this strategy can be widely utilized to modify potent lead compounds with low cell-permeability.

bortezomib prodrugs with reversible boronic ester bonds and then incorporating the resulting prodrugs into the nanoparticles via surface conjugation. Initially, several prodrug candidates were screened based upon boronic ester stability using isobutylboronic acid as a model boronic acid compound. The two most stable candidates were then selected to create surface conjugated bortezomib prodrugs on the liposomes
