Design, Synthesis and molecular docking study of hybrids of quinazolin-4(3H)-one as anticancer agents

A series of 4-(2-(4-substituted phenyl)-4-oxoquinazolin-3(4H)-yl)-N-(2-(4-fluorophenyl)-4-oxo-5-(arylidene)thiazolidin-3-yl) benzamides (VIa-n) have been synthesized by condensation of N-(2-(4-fluorophenyl)-4-oxothiazolidin-3-yl)-4-(4-oxo-2-(4-substituted phenyl)quinazolin-3(4H)-yl)benzamides (Va-b) with various aryl/heteroaryl aldehydes using conventional methodology. All compounds were screened for their in vitro anticancer activity against the human breast cancer cell lines (MCF-7), human lung cancer cell lines (A549) using MTT assay method and doxorubicin is used as standard drug. Compound VId, VIk and VIn showed high potency against A549 cell lines with IC50 values 0.035 +/- 0.002 mu M, 0.031 +/- 0.002 mu M and 0.030 +/- 0.002 mu M respectively compared to 0.023 +/- 0.002 mu M showed by the standard. However, highest activity against MCF-7 cell lines was exhibited by Va, Vb, VIk and VIn with IC50 values between 0.040 – 0.050 mu M. All the remaining compounds showed moderate anticancer activity against both the MCF-7 and A549 cell lines. To understand the interactions with active binding site of receptor, molecular docking study was also performed.

A series of 21 novel N-1-(2-aryl-1,3-thiazolidin-4-one)-N-3-aryl urea derivatives based on the previously identified lead compound I were synthesized and biologically characterized. The most promising compound 19a was identified as a multi-tyrosine kinase inhibitor, including c-Met, Ron, c-Kit, AXL and IGF-1R, etc. The results of real-time live-cell imaging indicated that compound 19a showed improved cytotoxicity and anti-proliferative activity against HT-29 cancer cells in a time- and dose-dependent manner, with an efficacy that was significantly greater than Cabozantinib. Flow cytometry and western blot analysis demonstrated the fact that anticancer activity was closely related with cancer cell apoptosis and the blockade of the phosphorylation of c-Met and its downstream signaling ERK and Akt. Furthermore, compound 19a also displayed slightly stronger effects on HT-29 cancer cells migration than that of Cabozantinib. (C) 2018 Elsevier Masson SAS. All rights reserved.

Hemisynthesis, crystal structure and inhibitory effect of sesquiterpenic thiosemicarbazones and thiazolidin-4-ones on the corrosion behaviour of stainless steel in 1 M H2SO4 solution

Treatment of thiosemicarbazones prepared from sesquiterpenes with ethyl 2-bromoacetate in the presence of sodium acetate afforded the corresponding thiazolidin-4-ones. The structures of all the newly synthesized compounds were established by considering spectral and single-crystal X-ray diffraction data. The title compound, ethyl 2-((Z)-2-{(Z)-[(1aR,5aR,9aS)-1,1-dichloro-1a, 5,5,7-tetramethyl-1a, 2,3,4,5,5a, 8,9-octahydro-1H-benzo[a] cyclopropa[b][7]annulen-8-ylidene]hydrazono}-4-oxothiazolidin-3-yl) acetate, C23H31Cl2N3O3S, 5, crystallizes in the orthorhombic noncentrosymmetric space group P2(1)2(1)2(1) with Z = 4. Within the molecule in the crystal structure, the cyclohexene ring has an envelope conformation and the cycloheptane ring, to which it is fused, has a boat conformation. In the crystal, molecules are linked by C-H center dot center dot center dot Cl hydrogen bonds forming chains propagating along the b-axis direction. The absolute configuration of the molecule in the crystal could be fully confirmed from anomalous dispersion effects [Flack parameter = -0.04 (2)]. Thiosemicarbazones 1 and 2 are efficient inhibitors for steel corrosion in 1 M H2SO4 solution, with a maximum efficiency of 92.28% at 10(-3) M. Furthermore, thiosemicarbazone compounds were found to be more efficient than thiazolidin-4-one derivatives. In addition, cyclic voltammetry was used to characterize the tested molecules, as well to estimate the experimental value of the energy band gap.
