Abstract
In this work, we have synthesized twenty five new 2-(5-(5-nitrofuran-2-yl)-1,3,4-thiadiazol-2-ylimino)thiazolidin-4-one derivatives bearing an aryl or heteroaryl methylene group on position 5 of thiazolidinone and evaluated their antimicrobial activity against Gram-positive and -negative bacteria as well as three metronidazole resistant Helicobacter pylori strains. Most of the compounds were very potent towards tested Gram-positive bacteria and showed an antibacterial efficacy substantially greater than ampicillin as the reference drug. However, no effectiveness was observed for the Gram-negative microorganisms. The compounds 9, 20 and 29 exhibited strong antimicrobial activity against Helicobacter pylori strains (inhibition zone > 30 mm) in 100 μg/disc and (inhibition zone > 20 mm) in 50 μg/disc. Taking these findings together, it seems that these potent antibacterial derivatives could be considered as promising agents for developing new anti-infectious drugs against microorganisms resistant to currently available antibiotics.

Abstract
Abstract The acetylcholinesterase and carbonic anhydrase inhibitors (AChEIs and hCAIs) remain key therapeutic agents for many bioactivities such as anti-Alzheimer and antiobesity antiepileptic, anticancer, antiinfective, antiglaucoma, and diuretic effects. Here, it has been attempted to discover novel multi-target AChEIs and hCAIs that are highly potent, orally bioavailable, may be brain penetrant, and have higher effectiveness at lower doses than tacrine and acetazolamide. After detailed investigations both in vitro and in silico, novel N-substituted sulfonyl amide derivatives (6a–j) were determined to be highly potent inhibitors for AChE and hCAs (KIs are in the range of 23.11–52.49 nM, 18.66–59.62 nM, and 9.33–120.80 nM for AChE, hCA I, and hCA II, respectively). Moreover, according to the cytotoxic effect studies, such as the ADME-Tox, cortex neuron cells, and neuroblastoma SH-SY5Y cell line, compounds 6a, 6d, and 6h, which are the most potent representative versus the target enzymes, were identified as orally bioavailable, highly selective, and brain preferentially distributed AChEIs and hCAIs. The docking studies revealed precise binding modes between 6a, 6d, and 6h and hCA II, hCA I, and AChE, respectively. The results presented here might provide a solid basis for further investigation into more potent AChEIs and hCAIs. Graphical abstract ![]()

Abstract
The NSAIDs ibuprofen was chemically conjugated to the PEG-graft-β-CyD with an ester bond and its aqueous solubility was clearly improved. The preliminary release profile of ibuprofen in rat gastrointestinal tract contents was performed at 37°C within 12 hours. The polymeric conjugate almost did not release ibuprofen in the contents of stomach, released ibuprofen only 7.4% in the contents of small intestine, and evidently released ibuprofen up to 58.7% in the contents of colon, respectively. These results demonstrated that the polymeric conjugate was site-specifically biodegraded in the rat colonic contents. On the other hand, the xylene-induced ear swelling technique, the hot plate test, and the brewer's yeast-induced hyperthermia model in mice were performed for evaluating the anti-inflammatory, analgesic, and antipyretic activities of the polymeric conjugate, respectively. The results revealed that the polymeric conjugate maintained a long and stable pharmacodynamic efficiency over a period of 24 hours. Hence, the present polymeric ibuprofen-cyclodextrin-PEG conjugate may be of value as an orally administered long-acting prodrug of ibuprofen through colon-targeting delivery.

Abstract
In the present investigation, a totally of 673 newly designed 2,6-diphenyl piperidin-4-one derivatives are docked with 2B7N protein of Helicobacter pylori which causes peptic ulcer disease. The docking studies revealed that 2,6-bis(3,4-dihydroxyphenyl)-3-phenethylpiperidin-4-one (BDPO) is identified as the most promising new compound with active nature against 2B7N with a binding affinity value of -8.0 Kcal/mol. The molecular structure of BDPO has been analyzed by DFT based theoretical calculations at the B3LYP/6-311++G(d,p) level of theory using the Gaussian 16W program package. The molecular electrostatic potential, Frontier molecular energy gap, and Mulliken population analysis have been used to understand the reactive site of the molecule. The stability and hyper-conjugative interactions were studied by natural bond orbital analysis (NBO) based on a second-order perturbation approach. The thermodynamic properties like thermal energy, specific heat capacity, and entropy at different temperatures were also calculated. The calculated first-order hyper polarizability results show that the title compound is 25.3 times greater than that of standard reference material, urea. So the title molecule is a good non-linear material. Also, this molecule has Van der Waals attraction and steric effect. It undergoes local excitation for the first five excitations.

Abstract
An efficient and environmental benign solvent-free synthesis of 5-amino-3-aryl-1-(6'-chloropyridazin-3'-yl)pyrazoles (4A-E): was accomplished by grinding 3-chloro-6-hydrazinopyridazine (2): and β-ketonitriles (3A-E): in the presence of p-toulenesulfonic acid as a catalyst. Subsequently, 6'-chloro group in 4A-E: was replaced with cyclic 2° amine derivatives viz. pyrrolidine 5A: , piperidine 5B: and morpholine 5C: to obtain 6A-E: , 7A-E: , 8A-E: respectively. The newly synthesized compounds were characterized by using IR, NMR (1H and 13C), mass spectral studies, elemental analyses. All the synthesized compounds were studied for their docking interaction with target protein 6COX and screened for their in vivo analgesic mode of action against swiss albino mice (animal model) using acetic-acid induced writhing test. Consequently, docking simulations data justifies the potential of synthesized series as an analgesic and very well correlated with in vivo study. Preliminary results revealed that most of the synthesized compounds exhibited moderate to good analgesic activity as compared to reference/standard drug (s) sodium diclofenac and candidates 4D: and 7C: protrude out as a promising lead for further investigation.

Abstract
Background: Benzimidazole and piperidine rings are important pharmacophore groups
for drug design studies.
</P><P>
Objective: In this study, we aimed to investigate the antidepressant-like activity of some 2-(4-
substituted-phenyl)-1-[2-(piperidin-1-yl)ethyl]-1H-benzimidazole derivatives.
</P><P>
Methods: Tail-suspension Test (TST) and Modified Forced Swimming Tests (MFST) were used to
assess antidepressant-like activities of the test compounds. Moreover, locomotor activity performances
of the animals were evaluated by an activity cage device.
</P><P>
Results: In the TST and MFST, compounds 2c-2h (10 mg/kg) and the reference drug fluoxetine (20
mg/kg) significantly reduced the immobility time of mice indicating the antidepressant-like activities
of these compounds. Further, in MFST, the same compounds induced significant enhancement
in the duration of active swimming behaviors without affecting the climbing performance of the
animals. This prolongation in the swimming time, similar to fluoxetine, pointed out that antidepressant-
like activity of the compounds 2c-2h might be related to the serotonergic rather than noradrenergic
mechanisms. Besides, results of the activity cage tests demonstrated that none of the tested
compounds caused an alteration in the locomotor activities of mice, signifying that antidepressantlike
effects presented in this study were specific.
</P><P>
Conclusion: In conclusion, results of this present study supported the previous papers reporting the
therapeutic potential of compounds carrying benzimidazole and/or piperidine rings in their structure
and emphasized, once again, the importance of these pharmacophore groups in drug design studies.

Abstract
Aim: The discovery of new generation of selective COX-2 inhibitors with potential analgesic and anti-inflammatory activity and minimal side effects is a major interest. Materials & methods: Novel imidazole and imidazo[1,5-a]quinazoline derivatives were prepared and evaluated for their analgesic and anti-inflammatory activities. COX-1/COX-2 isozyme selectivity testing and molecular docking were performed. Key physicochemical parameters were calculated. Results: All tested compounds exhibited significant activities compared with indomethacin as reference drug. Pharmacological evaluation showed that compounds 3c and 14c possess promising analgesic activity, pronouncing anti-inflammatory effect and reasonable COX-2 selectivity. Molecular docking attributed their good activity to their hydrogen bonding interaction with key amino acids in COX isozymes Arg120, Tyr355 and Ser530. Most compounds obeyed ‘Lipinski's rule of five’ and possess promising pharmacokinetic properties.

Abstract
1-Ethyl-3-methylimidazolium ethyl sulfate was synthesized and its supported ionic liquid phase form was prepared and used as an organocatalyst for the synthesis of substituted piperidinones and 3,4-dihydropyrimidinones. The ionic liquid was characterized by 1H NMR, 13C NMR, and mass spectrometry. The catalyst is novel, stable, completely heterogeneous, and recyclable for several times and can be easily recovered by filtration. It was characterized with scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, and energy-dispersive X-ray spectroscopy techniques. The workup procedures are very simple, and products were obtained in good-to-excellent yields with reasonable purities without the need for further chromatographic purification.
