Delmitide acetate  (Synonyms: RDP-58 acetate)

Delmitide (RDP58) acetate is an orally active d-isomer decapeptide with potent anti-inflammatory activity. Delmitide acetate inhibits production of TNF-α, IFN-γ, and interleukin (IL)-12, and up-regulates heme oxygenase 1 activity. Delmitide acetate can be used for the research of ulcerative colitis^[1][2].

Delmitide acetate (oral; 2.5, 5, 10 mg/kg; daily) significantly reduced CPT-11induced diarrhea, mucosal inflammation, and mortality in mice by suppressing the overproduction of proinflammatory cytokines TNF-a, IFN-y, and IL-12 in vivo^[2].
Delmitide acetate (oral; 2.5, 5, 10 mg/kg; daily) generates an enhanced tumor response and prolongation of time to relapse without concomitant Gl toxicity in mice^[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
