L-Norleucine is an isomer of leucine, specifically affects protein synthesis in skeletal muscle, and has antivirus activity.
L-Norleucine is an isomer of leucine, specifically affecting protein synthesis in skeletal muscle[1]. L-Norleucine has antiviral activity. L-Norleucine interacts with hnRNPA2/B1 protein to suppresses the expressions of Twist1 and Snail, two inhibitors of E-cadherin, and promotes the expression of E-cadherin, resulting in the inhibition of tumor metastasis[2].
