“…A study by Lv et al, [20] described that thiazolylpyrazole analogs shown moderate to the high inhibitory action of epidermal growth factor receptor tyrosine kinase (EGFR TK) with potential antitumor activity. Molecular docking of thiazolyl-pyrazolines indicated that it has a higher binding affinity to epidermal growth factor receptor kinase [21][22][23]. Many researchers investigated the biological activities of practically substituted heterocyclic compounds [24][25][26] which are commonly used in biodegradable agrochemicals [27][28][29] from shoddy research facilities as starting materials [30][31][32].…”

Background: Cancer is the world's second leading cause of death, accounting for an estimate of more than 10 million deaths annually. The most common type of cancers in women are breast, endometrial, cervical, ovarian, colorectal, lung, and skin cancers.Among these, breast cancer is the most common in women of all ages. Human epidermal growth factor receptor 2 breast cancer is widely seen in women which test positive for the protein HER2. This protein is present in one-fifth of every breast cancer cell, which promotes the growth of cancer cells. There are several compounds available for the treatment of HER2 breast cancer in the market with varying promise in their efficacy and safety on HER2 treatment. Objective: To design synthesis and evaluation of core scaffold pyrazolone fused thiazolidinone derivatives as anticancer agents. Methods: In this study, the core scaffold pyrazolone fused thiazolidinone derivatives were designed, synthesized, and analyzed for the anticancer activity using breast carcinoma cell line (MCF-7), against the standard drug Doxorubicin. Results: Many thiazoles, fused thiazole, and pyrazole derivatives have been found to have anti-cancer and other properties. In this study, the compound 1-phenyl-3-methyl-5-pyrazolones was allowed to react with diverse benzoyl chloride as well as primary amine derivatives and transformed into ’A series of Pyrazolone fused Thiazolidinone derivatives 4A1-4A10 and 4B1- 4B10. Computational studies by Schrodinger Glide XP using the Protein 3RCD which act on the human epidermal growth factor receptor’’ was performed on the selected scheme initially and further from the docked score data the synthesis of pyrazolone fused thiazolidinone was performed. Conclusion: Among the compounds synthesized, five compounds (4A6 − 3.4 kcal/mol, 4B4 − 3.0 kcal/mol, 4A3 − 2.2 kcal/mol, 4B2 − 1.6 kcal/mol, and 4A9 − 1.3 kcal/mol) shown promising binding affinities against epidermal growth factor receptor kinase. The cytotoxic potential of the compounds was examined using a breast carcinoma cell line (MCF-7), which shown cytotoxicity close to Doxorubicin (standard drug). Our findings are an important step forward in the development of novel anticancer agents.
