  The present invention relates to new pharmaceutical uses for compounds that exhibit activity as nitric oxide synthase (NOS) inhibitors. Specifically, it relates to the use of NOS inhibitors, particularly selective neuronal NOS (nNOS) inhibitors, alone or in combination with another active agent, in particular, either an SSRI or an NK-1 receptor antagonist, for the treatment of disorders or conditions the treatment which can be effected or facilitated by altering circadian rhythms. Examples of such disorders and conditions are blindness, obesity, seasonal affective disorder, bipolar disorder; jet lag, circadian sleep rhythms disorder, sleep deprivation, parasomnias, REM sleep disorders, hypersomnia, sleep-wake cycle disorders, narcolepsy and sleep disorders associated with shift work or irregular work schedules; nocturnal enuresis, and restless-legs syndrome.

  A series of 2-substituted 2-aminopropane-1,3-diols having a biphenyl moiety and their phosphate esters were synthesized to obtain sphingosine 1-phosphate receptor-1 (S1P(1)) receptor agonists with potent immunomodulatory activity accompanied by little or no effect on heart rate. Many of the synthesized compounds sufficiently decreased the number of peripheral blood lymphocytes. Some of the phosphates had potent agonism at S1P(1) but no agonism at S1P(3), which had been reported to be a receptor responsible for heart rate reduction. Although high S1P(1)/S1P(3) selectivity was considered to be favorable to reduce the effect on heart rate, almost all the phosphates showed a remarkable heart rate lowering effect in vivo. The results suggest that other factors in addition to S1P(3) agonism should be responsible for the heart rate reduction caused by S1P(1) agonists. Only 2-amino-2-[2-[2'-fluoro-4'-(4-methylphenylthio)biphenyl-4-yl]ethyl]propane-1,3-diol (6d) was identified as a desired S1P(1) receptor agonist having both the immunomodulatory activity and an attenuated effect on heart rate by a unique screening flow using in vivo evaluating systems primarily.
