EGFR kinase inhibitors from novel thiazole derivatives: synthesis, anticolon cancer, docking, and ADME studies.

The epidermal growth factor receptor (EGFR) is a key regulator of malignant cell growth and survival, making it an attractive target for cancer therapy. In this study, a new series of thiazole derivatives was rationally designed and synthesized as potential EGFR inhibitors and evaluated for their antiproliferative activity against two human colon cancer cell lines (HCT-116 and HT29). Several compounds exhibited potent anticancer activity, with compound 4j showing the highest potency, displaying half-maximal inhibitory concentration (IC50) values of 2.10 and 1.91 µM against HCT-116 and HT29 cells, respectively. Owing to its superior antiproliferative activity, compound 4j was further evaluated for EGFR inhibitory activity and demonstrated remarkable potency with an IC50 value of 0.27 µM. In addition, 4j exhibited a favorable selectivity index toward normal WI38 cells and effectively induced apoptosis through modulation of Bax, Bcl-2, and p53 expression. Molecular docking demonstrated strong binding interactions of 4j within the EGFR active site, while its ADME predictions supported its favorable drug-like profile. Overall, compound 4j represents a promising lead candidate for the development of novel EGFR-targeted anticancer agents.

Discovery of chromone-derived EGFR inhibitors as potent apoptosis inducers in cancer: In vitro and in vivo insights.

Compound 4v emerged as a leading candidate, showing EGFR kinase inhibitory activity comparable to Erlotinib, and computational analysis of 4v and EGFR molecular binding suggests that it serves as a superior binder to the inactive EGFR conformation.

Quinoline clubbed triazole hybrids as VEGFR-2 targeted anticancer agents: synthesis, molecular modeling, and biological evaluation

In silico and in vitro evaluation of new sulfonamide derivatives as VEGFR-2 inhibitors for cancer therapy.

Vascular endothelial growth factor receptor 2 (VEGFR-2) is a principal regulator of tumor progression and angiogenesis, which makes it an attractive target for developing and creating anticancer agents. A series of sulfonamide-derived compounds (K1-K5) were designed and evaluated for their ability to inhibit VEGFR-2 and for their cytotoxic activity against HCT-116 (colon), HepG-2 (liver), MCF-7 (breast) human cancer cells, and WI-38 (normal) fibroblasts. All of the compounds produced significant inhibition of VEGFR-2, with IC50values ranging from 0.0917 ± 0.028 µM (K5) to 1.2007 ± 0.013 µM (K1), relative to Sorafenib (IC50 = 0.0525 ± 0.017 µM). The most promising compound was K4, which produced potent inhibition of VEGFR-2 (IC50 = 0.1717 ± 0.027) and the highest selectivity index (SI) of all tested compounds: 25.6 (HCT-116), 14.8 (HepG-2), and 17.0 (MCF-7). In contrast to Sorafenib, whose Selectivity Index (SI) values range between 2.1 and 4.9, the SI values of both Vinblastine and Doxorubicin are less than 2.0 across these particular cell lines. This suggests that K4 has 12 times greater selectivity than Sorafenib and over 25 times greater selectivity than traditional chemotherapeutics. The increased selectivity of K4 can be attributed to the incorporation of a urea-linked sulfonamide moiety, which allows for the formation of hydrogen bonds and minimizes nonspecific hydrophobic interactions. Collectively, these data will demonstrate the importance of designing sulfonamide analogues with optimal structural characteristics to identify effective and specific VEGFR-2 inhibitors and that K4 represents a potentially important candidate for continued preclinical development.
