AI Article Synopsis

  • A series of novel quinazoline derivatives were created and tested as inhibitors for the EGFR kinase, with many showing strong inhibitory effects.
  • Compound 6g was particularly effective, demonstrating a low IC value of 5 nM against EGFR wild-type and strong activity against specific cancer cell lines.
  • The promising attributes of 6g, including selectivity, metabolic stability, and pharmacokinetics, indicate it has potential for further development in cancer treatment.

Article Abstract

A series of novel quinazoline derivatives bearing various C-6 benzamide substituents were synthesized and evaluated as EGFR inhibitors, and most showed significant inhibitory potency against EGFR kinase. In particular, compound 6g possessed potent inhibitory activity against EGFR wild-type (IC = 5 nM), and strong antiproliferative activity against HCC827 and Ba/F3 (L858R) cell lines. Kinase profiling against a panel of 365 kinases showed that 6g was highly selective for EGFR. Furthermore, 6g showed desirable properties in assays of liver microsome metabolic stability and cytochromes P450 inhibition and preliminary pharmacokinetic study. The overall attractive profile of 6g made it an interesting compound for further development.

Folic Acid-Modified Milk Exosomes Delivering c-Kit siRNA Overcome EGFR-TKIs Resistance in Lung Cancer by Suppressing mTOR Signaling and Stemness.

Int J Biol Sci

January 2025

Department of Medical Oncology, Cancer Center, West China Hospital, Sichuan University, Chengdu, Sichuan, China, 610041.

Article Synopsis
  • The study addresses a common issue in lung cancer treatment, where patients develop resistance to EGFR-TKIs like gefitinib, leading to worse outcomes.
  • The researchers developed a novel therapy using folic acid-modified milk exosomes loaded with c-kit siRNA (FA-mExo-siRNA-c-kit) to counteract this resistance by targeting the c-kit gene, which is linked to stemness traits in cancer cells.
  • Results showed that this approach not only reduced c-kit expression and stemness characteristics but also slowed tumor growth and improved survival in experimental models, highlighting its potential as a new treatment strategy for resistant lung cancer.

Bromodomain-containing protein 4 (BRD4) has been identified as a promising target in drug discovery, and the development of novel specific BRD4 bromodomain inhibitors will benefit anti-inflammatory drug discovery as well as bromodomain function role disclose. Herein, inspired by marine quinazolinone alkaloid penipanoid C, we designed and synthesized a series of quinazolin-4(3H)-ones with diverse linkers between two aromatic ring systems. Among them, compound 25 possessed good in vitro BRD4 inhibitory activities (IC = 3.

Cancer, characterized by uncontrolled growth and spread of abnormal cells potentially influencing almost all tissues in the body, is one of the most devastating and lethal diseases throughout the world. Chemotherapy is one of the principal approaches for cancer treatment, but multidrug resistance and severe side effects represent the main barriers to the success of therapy, creating a vital need to develop novel chemotherapeutic agents. The 1,2,3-triazole moiety can be conveniently constructed by "click chemistry" and could exert diverse noncovalent interactions with various enzymes in cancer cells.
