Comment: Marimastat (BB-2516) is a broad spectrum matrix metalloprotease (MMP) inhibitor. Its MMP inhibitory action has been applied to treating cancer [3,5]. Most recently marimastat has been reported to inhibit certain snake venom metalloproteases [2], with the implication that it could be repurposed as an antidote to snake venom poisoning [6].
