ROMURTIDE

Biological Activity

[Description]:

Romurtide (Muroctasin), a synthetic muramyl dipeptide derivative, is a cytokines inducer. Romurtide can increase peripheral neutrophils and monocytes in vivo and enhance production of colony-stimulating factors (CSFs), IL-1 and IL-6 in vitro[1].

Signaling Pathways >> Immunology/Inflammation >> Interleukin Related

Research Areas >> Inflammation/Immunology

[Target]

Cytokines[1]

[In Vitro]

Romurtide significantly enhances production of colony-stimulating factors (CSFs), interleukin-1 (IL-1) and interleukin-6 (IL-6) by the cells of monkey peripheral monocytes[1].

[In Vivo]

Romurtide (1 mg/head; s.c.; single dosage) increases significantly the number of peripheral neutrophils and monocytes in healthy cynomolgus monkeys[1]. Animal Model: Healthy cynomolgus monkeys[1] Dosage: 1 mg/head Administration: s.c.; single dosage Result: Increased significantly the number of peripheral neutrophils and monocytes.
