Biochem/physiol Actions

AAL-R [AAL(R)] is a FTY720 (fingolimod) analog and a much more rapidly activated sphingosine 1-phosphate receptor (S1P) agonist by sphingosine kinase 2 (SphK2)-mediated phosphorylation in vitro and in vivo. AAL-R triggers lymphocytes apoptosis in a SphK2-dependent manner (34%/84% remaining parental/SphK2-deficient Jurkat; 24 h 5 μM) with a significantly higher efficacy than its S-enantiomer AAL-S or FTY720 (%PI- mouse splenocytes = 27/ALL-R vs 56/FTY720 or ALL-S; 24 h 4 μM). AAL-R (0.1-0.3 mg/kg intratracheally), but not ALL-S, inhibits T-cell response to influenza infection and reduces pulmonary inflammation during Bordetella pertussis infection in mice (0.5 mg/kg intranasally).

Recent data have demonstrated the potential of sphingosine 1-phosphate (S1P) receptor (S1PR) agonism in the treatment of infectious diseases. A previous study used a murine model of Bordetella pertussis infection to demonstrate that treatment with the S1PR agonist AAL-R reduces

In asthma, excessive bronchial narrowing associated with thickening of the airway smooth muscle (ASM) causes respiratory distress. Numerous pharmacological agents prevent experimental airway hyperresponsiveness (AHR) when delivered prophylactically. However, most fail to resolve this feature after disease is instated. Although

The new immunosuppressant FTY720 (fingolimod), an analog of the endogenous lipid sphingosine, induces transient lymphopenia through the sequestration of lymphocytes in secondary lymphoid organs. Phosphorylation of FTY720 by sphingosine kinase 2 (SphK2) yields the active metabolite FTY720-phosphate (FTY-P), which induces

The mechanism by which locally delivered sphingosine analogs regulate host response to localized viral infection has never been addressed. In this report, we show that intratracheal delivery of the chiral sphingosine analog (R)-2-amino-4-(4-heptyloxyphenyl)-2-methylbutanol (AAL-R) or its phosphate ester inhibits the

Fluorescently labeled chiral analogs of the immunomodulatory drug FTY720 and its corresponding phosphates with variable aliphatic spacers between the aromatic ring and the NBD label have been synthesized. Determining the influence of the spacer on the in vitro phosphorylation rate
