Synthesis and antimicrobial activity of tetradentate ligands bearing hydrazone and/or thiosemicarbazone motifs and their diorganotin(IV) complexes

Four novel ligands derived from 2,3-butanedione have been synthesized, two dissymmetric thiosemicarbazone/3-hydroxy-2-naphthohydrazone ligands, H2L1 (bearing 4-isopropyl-3-thiosemicarbazone) and H2L2 (containing

Design, synthesis, and biological evaluations of (E)-2-(1-[2-mercapto-4-methyl-1-phenyl-1H-imidazol-5-yl]ethylidene)hydrazinecarbothioamide derivatives as antimicrobial agents

In recent year, the development of new drugs as antibacterial agents is an important resolution to overcome drug-resistant pathogens. Imidazole derivatives were synthesized using the microwave irradiation method and were characterized using spectral analysis techniques such as proton nuclear magnetic resonance, mass, and Fourier transform infrared spectroscopy. All the analogous were assessed for their in vitro antimicrobial activity and in silico; minimum inhibition concentration values of some conjugates were evaluated against extended spectrum beta-lactamases, vancomycin-resistant enterococci, and Methicillin-resistant Staphylococcus aureus strains from clinical samples. All the analogous were used as ligands in molecular docking and adsorption, distribution, metabolism, and excretion against saDHPS. Furthermore, compounds were also examined for their in vitro antituberculosis and antimalarial activity.

Synthesis and characterization of a new series of thiadiazole derivatives as potential anticancer agents

Cancer is one of the most common causes of death in the world. Despite the importance of combating cancer in healthcare systems and research centers, toxicity in normal tissues and the low efficiency of anticancer drugs are major problems in chemotherapy. Nowadays the aim of many medical research projects is to discover new safer and more effective anticancer agents. 1,3,4-Thiadiazole compounds are important fragments in medicinal chemistry because of their wide range of biological activities, including anticancer activities. The aim of this study was to determine the capacity of newly synthesized 1,3,4-thiadiazole compounds as chemotherapeutic agents. The structures of the obtained compounds were elucidated using 1H-NMR, 13C-NMR and mass spectrometry. Although the thiadiazole derivatives did not prove to be significantly cytotoxic to the tumour tissue cultures, compound 4i showed activity against the C6 rat brain cancer cell line (IC50 0.097 mM) at the tested concentrations.

Synthesis of novel quinoline-thiosemicarbazide hybrids and evaluation of their biological activities, molecular docking, molecular dynamics, pharmacophore model studies, and ADME-Tox properties

In the present study, a novel series of N-((substituted)carbamothioyl)-2,4-dimethylquinoline-3-carboxamide (7a-7s) was synthesized by microwave-assisted method. Structure of these derivatives was examined by spectroscopic techniques such as 1H NMR, 13C NMR, FT-IR, and ESI-MS. Further, the novel synthesized compounds were evaluated for their in-vitro biological activities against antibacterial, antifungal, antimalarial, and antituberculosis activity as well as for in-silico study. The antimalarial results demonstrated that compounds 7c and 7q (0.02 μg/mL) have notable potency against Plasmodium falciparum compared with chloroquine (0.02 μg/mL); compounds 7l (0.10 μg/mL), 7e, 7s (0.19 μg/mL), 7b, 7p (0.15 μg/mL), 7a, 7f, and 7f (0.25 μg/mL) also exhibited good activity against P. falciparum compared with quinine (0.26 μg/mL) as standard drug. Docking was performed on PFDHFR-TS, given the effect of compounds against the P. falciparum strain was excellent in comparison with standard drug. Molecular docking suggested that compounds 7b, 7i and 7c, 7e, and 7l closely bind with the active site of protein 3JSU and 4DP3, respectively, and compared with biological activity. We have also carried out molecular dynamics simulation on the best dock compound 7e complex with PDB: 3JSU to check the stability of docked complex and their molecular interaction. The calculated ADME-Tox descriptors for the synthesized compounds validated good pharmacokinetics properties, suggesting that these compounds could be used as hit for the development of the new active agents.

Novel 1,3,4-thiadiazole compounds as potential MAO-A inhibitors-design, synthesis, biological evaluation and molecular modelling

Monoamine oxidases (MAOs) are important drug targets for the management of neurological disorders. Herein, a series of new 1,3,4-thiadiazole derivatives bearing various alkyl/arylamine moieties as MAO inhibitors were designed and synthesized. All of the compounds were more selective against hMAO-A than hMAO-B. The half maximal inhibitory concentration (IC50) values of most of the compounds were lower than that of the common drug moclobemide (IC50 = 4.664 μM) and compound 6b was proven to be the most active compound (IC50 = 0.060 μM). Moreover, it was seen that compound 6b showed a similar inhibition profile to that of clorgyline (IC50 = 0.048 μM). The inhibition profile was found to be reversible and competitive for compound 6b with MAO-A selectivity. Molecular modelling studies aided in the understanding of the interaction modes between compound 6b and MAO-A. Furthermore, this compound was predicted to have a good pharmacokinetic profile and high BBB penetration. Therefore, such compounds are of interest towards developing new MAO inhibitors.

Synthesis, characterization and biological evaluation of novel 1-N-substituted thiocarbomoyl-3-ferrocenyl-2-pyrazoline derivatives

Some novel 1-N-substituted thiocarbomoyl-3-ferrocenyl-2-pyrazoline derivatives were synthesized and evaluated for in vitro antiamoebic activity against HM1:IMSS strain of Entamoeba histolytica. The results showed that most of the compounds exhibited promising activity (IC50 values in the range of 0.050-1.683 μM) than the reference drug metronidazole (IC50 = 1.78 μM). Active compounds were further screened for cytotoxicity against human embryonic kidney-293 (HEK-293) normal cell lines to ensure their toxic effect and the results revealed that active compounds were least toxic in the concentration range of 2.5-50 μM for 48 h and 2.5-25 μM for 72 h. At 100 μM for 48 h and at 50 μM for 72 h only four compounds 2c, 2h, 2k and 2l showed maximum viability and least cytotoxicity, respectively, concluding that all the screened compounds were least cytotoxic against human embryonic kidney-293 (HEK-293) normal cell lines in the concentration range of 2.5-50 and 2.5-25 μM.
