A pan-nitric oxide synthase (NOS) inhibitor, with potential immunomodulating and antineoplastic activities. Upon administration, tilarginine binds to and inhibits NOS, a free radical signaling molecule that promotes angiogenesis, metastasis, and immunosuppression in the tumor microenvironment (TME). Reduction in NOS activity may abrogate the immunosuppressive TME, enhance tumor antigen-specific immune response and inhibit tumor cell proliferation. Check for active clinical trials using this agent. (NCI Thesaurus)
