Novel thiazole derivatives 6, 7, 8 were designed and synthesized by cyclocondensation of compound 2 with 2-bromo-1-arylethan-1-one. This study focuses on the synthesis and characterization of the Cs/PAAC nanogel loaded with compounds 2, 6, 7 and 8. Their zeta potential values which remained negative -2.7, -6.3, -7.9 and - 3.9 mV respectively indicated their nanogel stability. Derivatives 2, 6, 7, 8 and their nanogels were examined against HCT-116, MCF-7, A549 and HepG2 using sorafenib and erlotinib as reference cytotoxic drugs. Generally, derivative 8 exhibited the highest anticancer activities while derivative 2 exhibited the lowest activities on the tested cell lines. Derivatives 8, 6 and 7 presented the uppermost cytotoxicity against HepG2 with IC50 = 6.35, 7.05 and 7.15 μM, consistently. The delivery nanogels considerably augmented our compounds cytotoxicity. Compound 8 nanogel enhanced cytotoxicity with decreased IC50 by 34.65 % (HepG2), 34.35 % (A549), 28.57 % (MCF-7) and 32.43 % (HCT116). Similarly, compound 7 nanogel improved anticancer activities with decreased IC50 by 32.17 % (HepG2), 30.61 % (A549), 26.01 % (MCF-7) and 26.54 % (HCT-116). Moreover, compound 6 nanogel enhanced cytotoxicity, with decreased IC50 by 31.91 % (HepG2), 29.80 % (A549), 26.47 % (MCF-7) and 26.88 % (HCT116). Additionally, cytotoxicity of 8, 7, 6, 2 and their nanogels were identified against VERO normal cells with IC50 = 25.55-37.10 μM. Also all products were assessed for dual inhibition of VEGFR-2 and EGFRT790M. Compounds 8, 6, 7 and their nanogels revealed very good inhibitions of VEGFR-2 at IC50 = 0.90-1.20 μM. As well, they highly inhibited EGFRT790M at IC50 = 0.25-0.50 μM. Furthermore, our compounds showed good in silico calculated ADMET profile.
