The invention relates to 4-[(3-ethynylphenyl)amino]-6,7-benzo-12-crown-quinazoline hydrochloride, its new crystalline forms, its therapeutic usage for treatment of diseases mediated by EGFR kinase and its combinatory therapeutic usage together with other therapeutic agents. The invention also provides synthetic methods for preparation of 4-[(3-ethynylphenyl)amino]-6,7-benzo-12-crown-quinazoline hydrochloride, its new crystalline forms, and the relevant synthetic intermediates for synthesis of 4-[(3-ethynylphenyl)amino]-6,7-benzo-12-crown-quinazoline hydrochloride.
Novel promising 4-anilinoquinazoline-based derivatives as multi-target RTKs inhibitors: Design, molecular docking, synthesis, and antitumor activities in vitro and vivo
4-Anilinoquinazoline derivatives function as tyrosine kinase inhibitors (TKIs). Novel TKIs are needed for cancer mutations and drug-resistant cells. We designed and synthesized 4-anilinoquinazoline derivatives with substitutions at quinazoline positions 6, 7 and 4 using a binding model with multi-target receptor tyrosine kinases, and assessed their antitumor activity against five human tumorcelllines (HepG2,
