JXL069

JXL069 is an experimental drug originally developed at the University of California, Los Angeles (UCLA) and licensed for development to Pelage Pharmaceuticals, which acts as a potent and selective mitochondrial pyruvate carrier (MPC) inhibitor that disrupts pyruvate import into mitochondria. It has been researched as a potential treatment for androgenetic alopecia and shows positive results in animal studies. Pelage Pharmaceuticals currently has a related candidate molecule PP405 in phase 2 clinical trials for hair loss formulated as a topical cream for the scalp.[1][2] MPC inhibitors also have potential for the treatment of cancer, so a large number of related molecules have also been developed, of which JXL069 was among the most effective tested so far for treatment of hair loss.[3][4][5][6][7][8] The drug is known to have been sold online in a grey market fashion for treatment of hair loss.[9] It has been believed to be PP405, but PP405 was said not to be JXL069 by Pelage Pharmaceuticals.[9]
