Description

Lisofylline [1-(5R-hydroxyhexyl)-3,7-dimethylxanthine] is a unique metabolite of pentoxifylline. Lisofylline inhibited the generation of phosphatidic acid and free fatty acids. Lisofylline blocked the release of pro-inflammatory cytokines in oxidative tissue injury, in response to cancer chemotherapy and in experimental sepsis. Lisofylline regulates immune cell function and autoimmune response by inhibition of IL-12 signalling and cytokine production. Lisofylline may have therapeutic value in the prevention of autoimmune disorders, including Type 1 diabetes, autoimmune recurrence following islet transplantation, and in preservation of beta cell functional mass during islet isolation.

Sample Use Guides

In Vivo Use Guide
A multicenter, randomized placebo-controlled trial was performed in patients with hematologic malignancies receiving bone marrow transplantation from HLA-identical sibling donors. Patients were randomized to receive either placebo, 2 mg/kg lisofylline or 3 mg/kg lisofylline every 6 h, beginning before conditioning and continuing to day 21 or hospital discharge.
Route of Administration: Intravenous
In Vitro Use Guide
Human blood was stimulated with various endotoxin preparations, zymosan, or protein A, and the levels of secreted monokines were measured by enzyme-linked immunosorbent assay. CT-1501R (lisofylline) inhibited tumor necrosis factor alpha (TNF-alpha), interleukin 1 beta (IL-1 beta), and IL-6 release in a dose-dependent manner and was active with all stimuli tested including Salmonella and Escherichia coli-derived endotoxin, endotoxin from both rough and smooth E. coli strains, as well as zymosan and protein A. CT-1501R inhibited monokine release by approximately 50% at 200 microM and 30% at 50 microM and was independent of the relative potency of stimulus. CT-1501R also inhibited IL-1 alpha or IL-1 beta induction of either TNF-alpha or IL-1 beta and inhibited the synergistic effects of stimulation with both human IL-1 beta and murine TNF-alpha on release of human TNF-alpha. Inhibition of monokine release following stimulation with monokine(s) was, in general, greater than that achieved with lipopolysaccharide (LPS) stimulation.
