The present invention relates to series of compounds as an inhibitor targeting Proliferating Cell Nuclear Antigen (PCNA). Pharmaceutical compositions of those compounds and methods of using them in the treatment of cancer are within the scope of this disclosure.

Disclosed herein are transfection complexes comprising at least one cell surface ligand; at least one helper lipid component; and a transfection enhancer. Also disclosed are pharmaceutical compositions comprising the disclosed transfection complexes, and a pharmaceutically acceptable carrier. Further, disclosed are methods of transfecting a cell, the method comprising the steps of: obtaining a transfection complex as disclosed; and contacting a cell with the transfection complex.

A peptide compound in the fields of pharmaceutical sciences, medicine, chemistry and biotechnology, that shows stability and ease of handling when compared to the more closely related peptidic compounds. A pharmaceutical composition that includes the peptidic compound and shows therapeutic results even when administered orally. In some embodiments, administration of the pharmaceutical composition provides superior therapeutic results when compared to the effects of hemopressin and cannabidiol. In some embodiments, oral administration of the pharmaceutical composition provides neuromodulation, both in the curative or prophylactic treatment of seizures, modulation of pain threshold and important neuroprotection, and reduction of the clinical symptoms of Multiple Sclerosis.

Various embodiments provide a homo-bivalent linker compound comprising identical functional groups at either end, methods of making such linker compounds, and methods of using the linker compounds.

The present invention relates to a metal phase transformation compound and a method for preparing the same.
