Eggshell is a hazardous waste by European Union regulations, so that discarded thousands of tons per year. To convert waste (eggshell) to wealth (catalyst), nano-magnetic eggshell was prepared based on the nano-Fe3O4, and then the eggshell was converted to Ca(HSO4)(2) with organic acid, namely, chlorosulfonic acid. Based on the back titration, 5.18mmol SO4H group was loaded per gram of the nano-structure. Using this method eggshell was converted to cheap, green and environment-friendly solid acid catalyst. The prepared catalyst (nano- Fe3O4@Ca(HSO4)(2)) was characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), and thermal gravimetric analysis (TGA). The activity of eggshell waste-derived catalysts was successfully evaluated in the synthesis of value-added products, namely indazolo[1,2-b]-phthalazinetrione derivatives as a benchmark multicomponent reaction. In addition, design of experiments shows that increase in amount of catalyst (and temperature), boost the reaction yield, especially with steeper slope at higher temperature.

The synthesis, structure, and in vitro anticancer activity of a new class of anticancer derivatives with dihydrobenzo[5,6]isoindolo[1,2-a]phthalazine and dihydrobenzo[f]pyridazino[6,1-a]isoindole skeletons are presented. The preparation is straight and efficient, involving two steps only: a N-alkylation of the pyridazine or phthalazine heterocycle, followed by a [3 + 2] dipolar cycloaddition of 1,2-diazinium ylides to the corresponding dipolarophiles. The synthesis was performed under microwave and ultrasound (US) irradiation as well as under conventional thermal heating. The most effective conditions in term of yields and time were found to be US irradiation. The penta- and tetra-cyclic 1,2-diazines were evaluated for their in vitro anticancer activity. The pentacyclic 1,2-diazine derivatives exhibit a significant anticancer activity against Non-Small Cell Lung Cancer NCI-H460, Leukemia MOLT-4, Leukemia CCRF-CEM, and Breast Cancer MCF7. A feasible explanation for anticancer efficiency of the pentacyclic 1,2-diazines have been furnished, being correlated with the mechanisms of action. The synthesis (conventional thermal heating, microwave and ultrasound irradiation), structure, and in vitro anticancer activity of a new class of anticancer molecules with polycyclic 1,2-diazines skeleton is presented.

Treatment of patients with triple-negative breast cancer (TNBC) is challenging due to the absence of well-defined molecular targets and the heterogeneity of such disease. In our endeavor to develop potent isatin-based anti-proliferative agents, we utilized the hybrid-pharmacophore approach to synthesize three series of novel isatin-based hybrids 5a-h, 10a-h and 13a-c, with the prime goal of developing potent anti-proliferative agents toward TNBC MDA-MB-231 cell line. In particular, compounds 5e and 10g were the most active hybrids against MDA-MB-231 cells (IC50 = 12.35 +/- 0.12 and 12.00 +/- 0.13 mu M), with 2.37-and 2.44-fold increased activity than 5-fluorouracil (5-FU) (IC50 = 29.38 +/- 1.24 mu M). Compounds 5e and 10g induced the intrinsic apoptotic mitochondrial pathway in MDA-MB-231; evidenced by the reduced expression of the anti-apoptotic protein Bcl-2, the enhanced expression of the pro-apoptotic protein Bax and the up-regulated active caspase-9 and caspase-3 levels. Furthermore, 10g showed significant increase in the percent of annexin V-FITC positive apoptotic cells from 3.88 to 31.21% (8.4 folds compared to control).

In this study, the structural properties, energetic data, and classification of the chemical properties of n,m-diazaphenanthrine derivatives were studied by a density functional theory (DFT) method. The important and proper indices were applied in this investigation. The structures, electronic properties, and chemical reactivities of 25 isomeric n,m-diazaphenanthrenes were studied by a B3LYP/6?31+G(d) method/basis set. All the optimized geometries of these isomers kept good planarity. The structural properties such as bond lengths and dipole moments of these isomers were calculated. The energies of frontier orbitals (HOMO and LUMO) are used to determine several chemical reactivity parameters as a measure of their relative stabilities. These include total energy (E), ionization potential (I), electron affinity (A), chemical hardness (?), chemical softness (S), electronic chemical potentials (?), and electrophilicity (?). Based on these calculations, the heats of formation (?H?(f)) for all the n,m-diazaphenanthrine derivatives are predicted. Benzo[h]quinazoline (P-13) and benzo[f]cinnoline (P-34) are calculated to be the most stable and the least stable isomers, respectively. 1,10-Phenanthroline (P-110) possesses the minimum electrophilicity, while benzo[c]cinnoline (P-56) is calculated to have the highest electrophilicity among the isomeric structures. The largest and smallest dipole moments are calculated for benzo[f]phthalazine (P-23) and 3,8-phenanthroline (P-38), respectively. Linear relationships between the calculated E-LUMO (in eV) values and electrophilicity (?) of the isomeric n,m-diazaphenanthrenes were observed.
