This inhibition can be beneficial in the treatment of various cancers, as the overexpression or mutation of EGFR is often associated with tumor growth and progression.
Used in Oncology Research:
In the field of oncology, PD 168393 is used for the acute inhibition of ErbB4, a receptor tyrosine kinase that is part of the HER family. ErbB4 is involved in cell growth, differentiation, and survival, and its dysregulation has been implicated in various cancers. By inhibiting ErbB4, PD 168393 can potentially disrupt cancer cell signaling pathways and hinder tumor growth.

4-[(3-BROMOPHENYL)AMINO]-6-ACRYLAMIDOQUINAZOLINE serves as a valuable compound in the development of novel therapeutic agents targeting EGFR and ErbB4. Its unique chemical structure allows for the design and synthesis of new drugs with improved potency, selectivity, and pharmacokinetic properties. These new drugs can be tailored to address specific cancer types or patient populations, offering more personalized treatment options.
Used in Biotechnology Applications:
In addition to its pharmaceutical applications, PD 168393 can also be utilized in biotechnology for the development of diagnostic tools and research reagents. Its ability to specifically target EGFR and ErbB4 makes it a promising candidate for the creation of targeted imaging agents, which can help visualize and monitor cancer progression in patients. Furthermore, PD 168393 can be employed in the development of high-throughput screening assays to identify new compounds with similar or improved inhibitory properties.

Synthesis and biological evaluation of 4-anilinoquinolines as potent inhibitors of epidermal growth factor receptor

The mutant receptor tyrosine kinase EGFR is a validated and therapeutically amenable target for genotypically selected lung cancer patients. Here we present the synthesis and biological evaluation of a series of 6- and 7-substituted 4-anilinoquinolines as potent type I inhibitors of clinically relevant mutant variants of EGFR. Quinolines 3a and 3e were found to be highly active kinase inhibitors in biochemical assays and were further investigated for their biological effect on EGFR-dependent Ba/F3 cells and non-small cell lung cancer (NSCLC) cell lines.

Structural insights into how irreversible inhibitors can overcome drug resistance in EGFR

Resistance to kinase- targeted cancer drugs has recently been linked to a single point mutation in the ATP binding site of the kinase. In EGFR, the crucial Thr790 gatekeeper residue is mutated to a Met and prevents reversible ATP competitive inhibitors from binding. Irreversible 4-(phenylamino)quinazolines have been shown to overcome this drug resistance and are currently in clinical trials. In order to obtain a detailed structural understanding of how irreversible inhibitors overcome drug resistance, we used Src kinase as a model system for drug resistant EGFR-T790M. We report the first crystal structure of a drug resistant kinase in complex with an irreversible inhibitor. This 4-(phenylamino)quinazoline inhibits wild type and drug resistant EGFR in vitro at low nM concentrations. The co-crystal structure of drug resistant cSrc-T338M kinase domain provides the structural basis of this activity.

6-Substituted-4-(3-bromophenylamino)quinazolines as putative irreversible inhibitors of the epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor (HER-2) tyrosine kinases with enhanced antitumor activity

A series of new 6-substituted-4-(3-bromophenylamino)quinazoline derivatives that may function as irreversible inhibitors of epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor (HER-2) tyrosine kinases have been prepared. These inhibitors have, at the C-6 position, butynamide, crotonamide, and methacrylamide Michael acceptors bearing water-solublilizing substituents. These compounds were prepared by acylation of 6-amino-4-(3-bromophenylamino)quinazoline with unsaturated acid chlorides or mixed anhydrides. We show that attaching a basic functional group onto the Michael acceptor results in greater reactivity, due to intramolecular catalysis of the Michael addition and/or an inductive effect of the protonated basic group. This, along with improved water solubility, results in compounds with enhanced biological properties. We present molecular modeling and experimental evidence that these inhibitors interact covalently with the target enzymes. One compound, 16a, was shown to have excellent oral activity in a human epidermoid carcinoma (A431) xenograft model in nude mice.
