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).

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

Type I and III IFNs play diverse roles in bacterial infections, being protective for some but deleterious for others. Using RNA-sequencing transcriptomics we investigated lung gene expression responses to Bordetella pertussis infection in adult mice, revealing that type I and

Incidence of whooping cough (pertussis), a bacterial infection of the respiratory tract caused by the bacterium Bordetella pertussis, has reached levels not seen since the 1950s. Antibiotics fail to improve the course of disease unless administered early in infection. Therefore

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
