The present invention relates to a novel preventive and/or therapeutic drug for myocardial infarction. The present invention provides a preventive and/or therapeutic drug for myocardial infarction or myocardial ischemia-reperfusion injury, the drug containing a lipid membrane structure retaining adenosine.

Prophylactic and/or therapeutic agent for cardiac infarction

The invention provides a nucleic-acid-transfecting composition which exhibits low cytotoxicity, which facilitates an effective nucleic acid transfection into a cell, and which improves expression of the nucleic acid in the cell. The composition for transfecting a nucleic acid into a cell, contains a di(Calkyl)dimethylammonium halide and a phospholipid.

Composition for nucleic acid transfection

To provide a nucleic-acid-transfecting composition which exhibits low cytotoxicity, which facilitates a nucleic acid transfection into cells, and which improves expression of the nucleic acid in the cells. The invention provides a composition for transfecting a nucleic acid into a cell, including a compound represented by the following formula (I) (wherein each of Rand R, which are identical to or different from each other, represents a saturated or unsaturated hydrocarbon group; Rrepresents a Calkyl group or a Chydroxyalkyl group; m is an integer from 1 to 10; and X represents a halogen atom), and a phospholipid.
