pentoxifylline

Pentoxifylline (PTX) modulates immunologic activity by stimulating cytokine production. Pentoxifylline is a methylxanthine derivative that inhibits phosphodiesterase and affects blood rheology. It also inhibits platelet aggregation and improves blood flow by increasing erythrocyte and leukocyte flexibility.

(R)-Lisofylline ((R)-Lisophylline) is an inhibitor of lysophosphatidic acid acyltransferase (IC50 = 0.6 µM) that interrupts IL-12 signaling-mediated STAT4 activation, making it useful for studies on the treatment of type 1 diabetes and autoimmune disorders.

Pentoxifylline-D6 is intended for use as an internal standard for the quantification of pentoxifylline by GC- or LC-MS. Pentoxifylline is a hemorrheologic agent. It increases the deformability of washed isolated human erythrocytes when used at a concentration of 100 µM. Pentoxifylline (1, 2, and 3 mM) inhibits ADP-induced platelet aggregation in isolated human whole blood. It inhibits thrombus formation induced by ADP in a hamster cheek pouch model when administered at doses of 5, 10, and 20 mg/kg. Formulations containing pentoxifylline have been used in the treatment of intermittent claudication.

Pentoxifylline impurity 1 is an impurity associated with Pentoxifylline.

Hydroxy Pentoxifylline-D6 is a deuterated compound of Hydroxy Pentoxifylline. Hydroxy Pentoxifylline (T21729) has a CAS number of 6493-06-7. (±)-Lisofylline is an enantiomer-specific, alkyl-substituted methylxanthine, which has specific and potent activity in down-regulating leukocyte activation. (±)-Lisofylline is an anti-inflammatory agent.

Ipenoxazone HCl is a glutamate receptor antagonist potentially for the treatment of Alzheimer's disease.

(S)-Lisofylline is the inactive optical enantiomer of (R)-lisofylline which is an anti-inflammatory agent. (S)-Lisofylline is exclusively converted to pentoxifylline in human liver microsomes.
