There is. I thought I had some on the shelf, but I must have used it up. Can't remember the name, but paint stores or big box stores should carry it. It will remove dried paint from brushes, even loosen dried paint in sprayers. Has a very bad/strong odor, so use in a well ventilated area. You just have to decide if buying the cleaner and spending the time cleaning the brush is worth it or if it's better to just pitch it like chrisn suggested.
