WWL113 is a selective and orally active Ces3 and Ces1f inhibitor (IC50: 120 nM and 100 nM for Ces3 and Ces1f, respectively). WWL113 appears to display excellent selectivity for the 60-kDa serine hydrolase.
NT113 is a pan-ERBB inhibitor with high brain penetrance. NT113 is active against GBM xenografts in which wild-type EGFR or EGFRvIII is highly expressed. NT113 inhibits the growth of glioblastoma xenografts with EGFR amplification. NT113 has inhibitory ac
