K145is inactive against SphK1 and other protein kinases. K145 induces cell apoptosis and has potently antitumor activity. K145is a selective, substrate-competitive and orally active SphK2 inhibitor with an IC50 of 4.3 µM and a Ki of 6.4 µM.
T145 inhibits growth of Enterococcus faecalis, Staphylococcus aureus and Mycobacterium tuberculosis (Mtb) with sub μg/ml potencies that are potentially therapeutically valuable. T145 minimizes selection of spontaneous resistant mutants, a trait that prolo
