TG100-115, inhibited PI3K γ and -δ(IC50 values of 83 and 235 nM, respectively), whereas both PI3Kα and -β were relatively unaffected (IC50 values>1 μM). As a gauge of general specificity, TG100-115 was also assayed against a 133 protein kinase panel, none of which was inhibited at IC50 values <1 μM. [ 2,3]
TG100-115 is applied to anti-inflammatory therapy for respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). TG100-115 could reduce inflammation and mucin accumulation.
