A noncleavable paclitaxel (PTX) and N-acetylmuramyl-l-alanyl-d-isoglutamine (MDP) derivative conjugate, 22 (DY-16-43), and its analogues were prepared and characterized as antagonists of NOD2 signaling. This conjugate enhanced the antitumor and antimetastatic efficacy of PTX in Lewis lung carcinoma (LLC) tumor-bearing mice. This work first describes a molecular strategy that enables the sensitization

The present invention relates to a novel heteroaryl compound, an enantiomer, a diastereomer or a pharmaceutically acceptable salt thereof, and an antiviral composition comprising the same as an active ingredient. The novel compounds represented by formula (I) or formula (II) according to the present invention are remarkably superior in antiviral activity against an influenza virus, and furthermore, have low cytotoxicity and thus low adverse effects on a human body. Therefore, a pharmaceutical composition containing the same as an active ingredient can be effectively used for the prevention or treatment of diseases caused by an influenza virus infection.
