L-NMMA citrate
Based on 11 publication(s) in Google Scholar
L-NMMA (Tilarginine) citrate is a non-selective and competitive inhibitor of nitric oxide synthase. L-NMMA citrate inhibits three subtypes, namely nNOS, eNOS, and iNOS, and reduces NO production. L-NMMA citrate alleviates mechanical allodynia, thermal hyperalgesia, and choroidal fibrosis. L-NMMA citrate is applicable to research related to nociception, bone cancer pain, and myopia.
