Novel 5- and 6-subtituted benzothiazoles with improved physicochemical properties: Potent S1P1 agonists with in vivo lymphocyte-depleting activity
摘要:
An SAR campaign designed to increase polarity in the 'tail' region of benzothiazole 1 resulted in two series of structurally novel 5- and 6-substituted S1P(1) agonists. Structural optimization for potency ultimately delivered carboxamide (+)-11f, which in addition to possessing improved physicochemical properties relative to starting benzothiazole 1, also displayed good S1P(3) selectivity and acceptable in vivo lymphocyte-depleting activity.
