				 The   quinazoline   derivative   4-(4’-hydroxyphenyl)-amino-6,7-dimethoxyquinazoline   (WHI-P131/JANEX-1;   CAS    202475-60-3) is a dual-function inhibitor of Janus kinase 3 (JAK3) and Epidermal Growth Factor (EGF) receptor kinase.  A PEGylated liposomal nanoparticle formulation of GMP-grade WHI-P131 exhibited potent in vivo activity against breast  cancer cells. Notably, this therapeutic nanoparticle formulation of GMP-grade WHI-P131 was substantially more effective  than  the  standard  chemotherapy  drugs  paclitaxel,  gemcitabine,  and  ge fi   tinib  against  chemotherapy-resistant  breast   cancer in the MMTV/ Neu  transgenic mouse model. These experimental results demonstrate that the nanotechnology- enabled delivery of WHI-P131 shows therapeutic potential against breast cancer. .. View More»
