Abstract
In this work, two novel chalcone-based imidazothiazole derivatives ITC-1 and ITC-2 were synthesized and characterized by 1H NMR, 13C NMR and high-resolution mass spectrometry with electrospray ionization, and chemical structure of ITC-1 was confirmed by single-crystal X-ray diffraction. Also, the anticancer activity of ITC-1 and ITC-2 was evaluated. First, antiproliferative activity tests were performed against cancer cells namely, human-derived breast adenocarcinoma (MCF-7), lung carcinoma (A-549), and colorectal adenocarcinoma (HT-29) cell lines, and mouse fibroblast healthy cell line (3T3-L1) by XTT assay. Afterward, mitochondrial membrane disruption (MMP), caspase activity, and apoptosis tests were performed on MCF-7 cells to elucidate the anticancer mechanism of action of the test compounds by flow cytometry analysis. XTT results revealed that both compounds exhibited a very high degree of antiproliferative effects on each tested cancer cell line with very low IC50 values while showing much lower antiproliferation on 3T3-L1 normal cells with much higher IC50 values. Besides, ITC-2 was determined to have a striking cytotoxic power competing with the chemotherapeutic drug carboplatin. Flow cytometry results demonstrated the mitochondrial-mediated apoptotic effects of both compounds through membrane disruption and multi-caspase activation in MCF-7 cells. Finally, molecular docking studies were performed to determine the structural understanding of the test compounds by their interactions on caspase-3 and DNA dodecamer enzymes, respectively. The interactions between the compound and the crystal structure were determined according to parameters such as free binding energies (ΔGBind), Glide score values, and determination of the active binding site. The obtained data suggest that ITC-1 and ITC-2 may be considered remarkable anticancer drug candidates. In addition to molecular docking via in silico approaches, the pharmacokinetic properties of compounds ITC-1 and ITC-2 were calculated using the Schrödinger 2021-2 Qikprop wizard.Communicated by Ramaswamy H.

Abstract
In this work, a novel crystal, (E)-4-(4-methylbenzyl)-6-styrylpyridazin-3(2H)-one (E-BSP) was synthesized via Knoevenagel condensation of benzaldehyde and (E)-6-(4-methoxystyryl)-4,5-dihydropyridazin-3(2H)-one. The molecular structure of E-BSP was confirmed by using FT-IR, 1H-NMR, 13C-NMR, UV-vis, ESI-MS, TGA/DTA thermal analyses and single crystal X-ray diffraction. The DFT/B3LYP methods with the 6-311++G(d,p) basis set were used to determine the vibrational modes over the optimized structure. Potential energy distribution (PED) and the VEDA 4 software were used to establish the theoretical mode assignments. The same approach was used to compute the energies of frontier molecular orbitals (HOMO-LUMO), global reactivity descriptors, and molecular electrostatic potential (MEP). Additionally, experimental and computed UV spectral parameters were determined in methanol and the obtained outputs were supported by FMO analysis. Molecular docking and molecular dynamics (MD) simulation analyses of the E-BSP against six proteins obtained from different cancer pathways were carried out. The proteins include; epidermal growth factor receptor (EGFR), Estrogen receptor (ERα), Mammalian target of rapamycin (mTOR), Progesterone receptor (PR) (Breast cancer), Human cyclin-dependent kinase 2 (CDK2) (Colorectal cancer), and Survivin (Squamous cell carcinoma/Non-small cell lung cancer). The results of the analyses showed that the compound had less binding energies ranging between -6.30 to -9.09 kcal/mol and formed stable complexes at the substrate-binding site of the proteins after the 50 ns MD simulation. Therefore, E-BSP was considered a potential inhibitor of different cancer pathways and should be used for the treatment of cancer after experimental validation and clinical trial.Communicated by Ramaswamy H.

Abstract
Three intramolecular hydrogen bonds are observed in the title compound. In the crystal, molecules are connected by C—H⋯Cl and N—H⋯O hydrogen bonds. In the title compound, C18H15ClN3O+·Cl−·2H2O, three intramolecular hydrogen bonds are observed, N—H⋯O, O—H⋯Cl and O—H⋯O. In the crystal, molecules are connected by C—H⋯Cl and N—H⋯O hydrogen bonds. Strong C—H⋯Cl, N—H⋯O, O—H⋯Cl and O—H⋯O hydrogen-bonding interactions are implied by the Hirshfeld surface analysis, which indicate that H⋯H contacts make the largest contribution to the overall crystal packing at 33.0%.

Abstract
In the crystal, molecules are linked by C—H⋯O hydrogen bonds, generating (5) and (28) ring motifs. In addition, weak C—H⋯π and π-stacking interactions are observed. The title compound, C22H15N3O4, is built up from a central imidazo[1,2-a]pyridine ring system connected to a nitroso group, a phenyl ring and a 2-oxo-2-phenylethyl acetate group. The imidazo[1,2-a] pyridine ring system is almost planar (r.m.s. deviation = 0.017 Å) and forms dihedral angles of 22.74 (5) and 45.37 (5)°, respectively, with the phenyl ring and the 2-oxo-2-phenylethyl acetate group. In the crystal, the molecules are linked into chains parallel to the b axis by C—H⋯O hydrogen bonds, generating R21 (5) and R44 (28) graph-set motifs. The chains are further linked into a three-dimensional network by C—H⋯π and π-stacking interactions. The intermolecular interactions were investigated using Hirshfeld surface analysis and two-dimensional fingerprint plots, revealing that the most important contributions for the crystal packing are from H⋯H (36.2%), H⋯C/C⋯H (20.5%), H⋯O/O⋯H (20.0%), C⋯O/O⋯C (6.5%), C⋯N/N⋯C (6.2%), H⋯N/N⋯H (4.5%) and C⋯C (4.3%) interactions.

Abstract
The title Schiff base, C22H24N2O6, adopts an E configuration. The mol-ecule is planar, the mean planes of the phenyl ring system (r.m.s deviation = 0.0059 Å) forms a dihedral angle of 0.96 (4)° with the mean plane of the phenyl ring moiety (r.m.s deviation = 0.0076 Å). In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds into chains extending along the c-axis and b-axis directions, respectively. A mol-ecular docking study between the title mol-ecule and 5-HT2C, which is a G protein receptor and ligand-gated ion channels found in nervous systems (PDB ID: 6BQH) was executed. The experiment shows that it is a good potential agent because of its affinity and ability to stick to the active sites of the receptor.

Abstract
The pyridazine ring in the title compound, C20H17ClN2O3, adopts a screw-boat conformation. The whole mol-ecule is flattened, the dihedral angles subtended by the least-squares plane of the central aromatic ring with those of the terminal benzene and pyridazine rings being 15.18 (19) and 11.23 (19)°, respectively. In the crystal, the mol-ecules are linked by pairs of N-H⋯O bonds into centrosymmetric dimers and by C-H⋯π contacts into columns. The results of the Hirshfeld surface analysis show that the most prominent inter-actions are H⋯H, accounting for 36.5% of overall crystal packing, and H⋯O/O⋯H (18.6% contribution) contacts.

Abstract
The title pyridazinone derivative, C19H14Cl2N2O, an important pharmacophore with a wide variety of biological applications is not planar, the chloro-phenyl and pyridazinone rings being almost perpendicular, subtending a dihedral angle of 85.73 (11)°. The phenyl ring of the styryl group is coplanar with the pyridazinone ring [1.47 (12)°]. In the crystal, N-H⋯O hydrogen bonds form inversion dimers with an R 2 2(8) ring motif and C-H⋯Cl hydrogen bonds also occur. The roles of the inter-molecular inter-actions in the crystal packing were clarified using Hirshfeld surface analysis, and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H⋯H (37.9%), C⋯H/H⋯C (18.7%), Cl⋯H/ H⋯Cl (16.4%) and Cl⋯C/C⋯Cl (6.7%) contacts.

Abstract
In this study, we present the synthesis of novel pyridazin-3(2H)-one derivative namely (E)-4-(4-methylbenzyl)-6-styrylpyridazin-3(2H)-one (MBSP). The chemical structure of MBSP was characterized using spectroscopic techniques such as FT-IR, 1H NMR, 13C NMR, UV-Vis, ESI-MS, and finally, the structure was confirmed by single X-ray diffraction studies. The DFT calculation was performed to compare the gas-phase geometry of the title compound to the solid-phase structure of the title compound. Furthermore, a comparative study between theoretical UV-Vis, IR, 1H- and 13C NMR spectra of the studied compound and experimental ones have been carried out. The thermal behavior and stability of the compound were analyzed by using TGA and DTA techniques which revealed that the compound is thermostable up to its melting point. Finally, the in silico docking and ADME studies are performed to investigate whether MBSP is a potential therapeutic for COVID-19.

Abstract
Two polymorphs of the title compound, C19H16N2O3, were obtained from ethano-lic (polymorph I) and methano-lic solutions (polymorph II), respectively. Both polymorphs crystallize in the monoclinic system with four formula units per cell and a complete mol-ecule in the asymmetric unit. The main difference between the mol-ecules of (I) and (II) is the reversed position of the hy-droxy group of the carb-oxy-lic function. All other conformational features are found to be similar in the two mol-ecules. The different orientation of the OH group results in different hydrogen-bonding schemes in the crystal structures of (I) and (II). Whereas in (I) inter-molecular O-H⋯O hydrogen bonds with the pyridazinone carbonyl O atom as acceptor generate chains with a C(7) motif extending parallel to the b-axis direction, in the crystal of (II) pairs of inversion-related O-H⋯O hydrogen bonds with an R 2 2(8) ring motif between two carb-oxy-lic functions are found. The inter-molecular inter-actions in both crystal structures were analysed using Hirshfeld surface analysis and two-dimensional fingerprint plots.

Abstract
In the title compound, C10H10N2OS, the five atoms of the thio-phene ring are essentially coplanar (r.m.s. deviation = 0.0037 Å) and the pyridazine ring is non-planar. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into dimers with an R 2 2(8) ring motif. The dimers are linked by C-H⋯O inter-actions, forming layers parallel to the bc plane. The theoretical geometric parameters are in good agreement with XRD results. The inter-molecular inter-actions were investigated using a Hirshfeld surface analysis and two-dimensional fingerprint plots. The Hirshfeld surface analysis of the title compound suggests that the most significant contributions to the crystal packing are by H⋯H (39.7%), C⋯H/H⋯C (17.3%) and O⋯H/H⋯O (16.8%) contacts.

Abstract
In the title compound, the phenyl and pyridazine rings are inclined to each other by 10.55 (12)°, whereas the 4-methylbenzyl ring is nearly orthogonal to the pyridazine ring with a dihedral angle of 72.97 (10)°. The title pyridazinone derivative, C20H18N2O3, is not planar. The phenyl ring and the pyridazine ring are inclined to each other by 10.55 (12)°, whereas the 4-methylbenzyl ring is nearly orthogonal to the pyridazine ring, with a dihedral angle of 72.97 (10)°. In the crystal, molecules are linked by pairs of O—H⋯O hydrogen bonds, forming inversion dimers with an R22(14) ring motif. The dimers are linked by C—H⋯O hydrogen bonds, generating ribbons propagating along the c-axis direction. The intermolecular interactions were additionally investigated using Hirshfeld surface analysis and two-dimensional fingerprint plots. They revealed that the most significant contributions to the crystal packing are from H⋯H (48.4%), H⋯O/O⋯H (21.8%) and H⋯C/C⋯H (20.4%) contacts. Molecular orbital calculations providing electron-density plots of HOMO and LUMO molecular orbitals and molecular electrostatic potentials (MEP) were also computed, both with the DFT/B3LYP/6–311 G++(d,p) basis set.

Abstract
In the title compound, intermolecular C—H⋯O, O—H⋯O and N—H⋯O hydrogen bonds link the molecules into a three-dimensional supramolecular network. In the title compound, C13H14N2O3, the dihydropyridazine ring (r.m.s. deviation = 0.166 Å) has a screw-boat conformation. The dihedral angle between its mean plane and the benzene ring is 0.77 (12)°. In the crystal, intermolecular O—H⋯O hydrogen bonds generate C(5) chains and N—H⋯O hydrogen bonds produce R22(8) motifs. These types of interactions lead to the formation of layers parallel to (12). The three-dimensional network is achieved by C—H⋯O interactions, including R24(8) motifs. Intermolecular interactions were additionally investigated using Hirshfeld surface analysis and two-dimensional fingerprint plots. The most significant contributions to the crystal packing are by H⋯H (43.3%), H⋯C/C⋯H (19.3%), H⋯O/H⋯O (22.6%), C⋯N/N⋯C (3.0%) and H⋯N/N⋯H (5.8%) contacts. C—H⋯π interactions and aromatic π–π stacking interactions are not observed.

Abstract
In each asymmetric unit of the title compounds, one independent molecule is present. In the crystal structure of 4-benzyl-6-phenyl-4,5-dihydropyridazin-3(2H)-one, adjacent molecules are linked by a pair of N—H⋯O hydrogen bonds, forming inversion dimers with an (8) ring motif. The crystal structure of methyl 2-[5-(2,6-dichlorobenzyl)-6-oxo-3-phenyl-1,6-dihydro-pyridazin-1-yl]acetate displays intermolecular C—H⋯O interactions. The asymmetric units of the title compounds both contain one nonplanar molecule. In 4-benzyl-6-phenyl-4,5-dihydropyridazin-3(2H)-one, C17H14N2O, (I), the phenyl and pyridazine rings are twisted with respect to each other, making a dihedral angle of 46.69 (9)°; the phenyl ring of the benzyl group is nearly perpendicular to the plane of the pyridazine ring, the dihedral angle being 78.31 (10)°. In methyl 2-[5-(2,6-dichlorobenzyl)-6-oxo-3-phenyl-1,4,5,6-tetrahydropyridazin-1-yl]acetate, C20H16Cl2N2O3, (II), the phenyl and pyridazine rings are twisted with respect to each other, making a dihedral angle of 21.76 (18)°, whereas the phenyl ring of the dichlorobenzyl group is inclined to the pyridazine ring by 79.61 (19)°. In the crystal structure of (I), pairs of N—H⋯O hydrogen bonds link the molecules into inversion dimers with an R22(8) ring motif. In the crystal structure of (II), C—H⋯O hydrogen bonds generate dimers with R12(7), R22(16) and R22(18) ring motifs. The Hirshfeld surface analyses of compound (I) suggests that the most significant contributions to the crystal packing are by H⋯H (48.2%), C⋯H/H⋯C (29.9%) and O⋯H/H⋯O (8.9%) contacts. For compound (II), H⋯H (34.4%), C⋯H/H⋯C (21.3%) and O⋯H/H⋯O (16.5%) interactions are the most important contributions.

Abstract
In this paper, we describe the synthesis of a new di-hydro-2H-pyridazin-3-one derivative. The mol-ecule, C18H16N2O, is not planar; the benzene and pyridazine rings are twisted with respect to each other, making a dihedral angle of 11.47 (2)°, and the toluene ring is nearly perpendicular to the pyridazine ring, with a dihedral angle of 89.624 (1)°. The mol-ecular conformation is stabilized by weak intra-molecular C-H⋯N contacts. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into inversion dimers with an R 2 2(8) ring motif. The inter-molecular inter-actions were investigated using Hirshfeld surface analysis and two-dimensional (2D) fingerprint plots, revealing that the most important contributions for the crystal packing are from H⋯H (56.6%), H⋯C/C⋯H (22.6%), O⋯H/H⋯O (10.0%) and N⋯C/C⋯N (3.5%) inter-actions.

Abstract
The title pyridazin-3(2H)-one derivative, C25H19FN2O2, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In mol-ecule A, the 4-fluoro-phenyl ring, the benzyl ring and the phenyl ring are inclined to the central pyridazine ring by 86.54 (11), 3.70 (9) and 84.857 (13)°, respectively. In mol-ecule B, the corresponding dihedral angles are 86.80 (9), 10.47 (8) and 82.01 (10)°, respectively. In the crystal, the A mol-ecules are linked by pairs of C-H⋯F hydrogen bonds, forming inversion dimers with an R 2 2(28) ring motif. The dimers are linked by C-H⋯O hydrogen bonds and a C-H⋯π inter-action, forming columns stacking along the a-axis direction. The B mol-ecules are linked to each other in a similar manner and form columns separating the columns of A mol-ecules.

The asymmetric unit of the title compound, C17H12Cl2N2O, contains one independent mol-ecule. The mol-ecule is not planar, the phenyl and pyridazine rings are twisted with respect to each other, making a dihedral angle of 29.96 (2)° and the di-chloro-phenyl ring is nearly perpendicular to the pyridazine ring, with a dihedral angle of 82.38 (11)°. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules to form inversion dimers with an R 2 2(8) ring motif. The dimers are linked by C-H⋯O inter-actions, forming layers parallel to the bc plane. The inter-molecular inter-actions were investigated using Hirshfeld surface analysis and two-dimensional fingerprint plots, and the mol-ecular electrostatic potential surface was also analysed. The Hirshfeld surface analysis of the title compound suggests that the most significant contributions to the crystal packing are by H⋯H (31.4%), Cl⋯H/H⋯Cl (19.9%) and C⋯H/H⋯C (19%) contacts.

Abstract
The asymmetric unit of the title compound, C18H13N3S, is build up from two independent molecules slightly inclined to each other. In each molecule, the imidazo[1,2-a]pyridine ring system is almost planar, with the largest deviation from the mean plane being 0.022 (1) Å in the first molecule and 0.018 (1) Å in the second molecule. The fused-ring system belonging to the first molecule makes dihedral angles of 24.06 (7) and 40.52 (8)° with the thiophenyl and phenyl rings, respectively. The corresponding values observed in the second molecule are nearly the same, namely 25.20 (7) and 38.99 (7)°, respectively. The dihedral angle between the thiophenyl and phenyl rings is 63.47 (9)° in the first molecule and 47.49 (9)° in the second. The cohesion of the crystal structure is ensured by two C—H...N hydrogen bonds between molecules and by three C—H...π interactions, forming a three-dimensional network.

Abstract
In the title compound, C15H11N3O4, the imidazo[1,2-a] pyridine ring system is almost planar [r.m.s. deviation = 0.028 (2) Å]. Its mean plane makes dihedral angles of 33.92 (7) and 34.56 (6)° with the meth-oxy-phenyl ring and the nitro group, respectively. The cohesion of the crystal structure is ensured by C-H⋯N and C-H⋯O hydrogen bonds, forming layers almost parallel to the ac plane.

Abstract
The mol-ecule of the title compound, C21H17N3O, is built up from fused five- and six-membered rings connected to a methyl group, a phenyl ring and an (imino-meth-yl)phenol group. The fused ring system is almost planar (r.m.s. deviation = 0.031 Å) and forms dihedral angles of 64.97 (7) and 18.52 (6)° with the phenyl ring and the (imino-meth-yl)phenol group, respectively. In the crystal, centrosymmetric mol-ecules are linked by pairs of C-H⋯π inter-actions into dimeric units, which are further connected by O-H⋯N hydrogen bonds to form layers parallel to (101).

Abstract
In the title compound, C9H10N2O, the imidazo[1,2-a]pyridine moiety is approximately planar (r.m.s. deviation = 0.024 Å). The methanol group is nearly perpendicular to its mean plane as indicated by the C-C-C-O and N-C-C-O torsion angles of 80.04 (16) and -96.30 (17)°, respectively. In the crystal, mol-ecules are linked by O-H⋯N hydrogen bonds, forming inversion dimers with an R (2) 2(10) ring motif. The dimers are liked via C-H⋯O hydrogen bonds, enclosing R (2) 2(10) ring motifs and forming ribbons along [201]. The ribbons are linked via a number of π-π inter-actions [centroid-centroid distances vary from 3.4819 (8) to 3.7212 (8) Å], forming a three-dimensional structure.
