Synthesis and antibacterial activity of novel Schiff bases of thiosemicarbazone derivatives with adamantane moiety

Increased bacterial resistance to antibiotics is a major threat to human health, and it is particularly important to develop novel antibiotic drugs. Here, we designed a series of Schiff base thiosemicarbazone derivatives containing an adamantane moiety, and carried out the structural characterization of the compounds and in vitro antibacterial activity tests. Compound 7e was as effective as the commonly used antibiotic ampicillin against the Gram-negative bacterium Escherichia coli, and compound 7g had a good inhibitory effect against Gram-positive Bacillus subtilis. These findings provide data for the development of better thiosemicarbazone antibacterial agents.

Synthesis and antitumor activity of novel pyridazinone derivatives containing 1,3,4-thiadiazole moiety

A series of novel pyridazinone derivatives containing the 1,3,4-thiadiazole moiety were synthesized and characterized by 1H NMR, 13C NMR, spectroscopies HRMS and IR. Among them, the structure of compound 5c (2-(Tert-butyl)?4-chloro-5-((5-((2-ethylphenyl)amino)?1,3,4-thiadiazol-2-yl)thio)pyridazin-3(2H)-One) was unambiguously confirmed via single crystal X-ray diffraction analysis. The inhibitory activity of all the target compounds against MGC-803 and Bcap-37 was determined by MTT assay, with doxorubicin (the inhibition rates were 95.5 ± 0.4% and 95.7 ± 1.0% respectively) as a control. The preliminary results showed that the inhibitory activity of compound 5n (2-(Tert-butyl)?4-chloro-5-((5-((3-fluorophenyl)amino)?1,3,4-thiadiazol-2-yl)thio)pyridazin-3(2H)-One) was superior to the others. The inhibition rates of MGC-803 and Bcap-37 cells were 86.3 ± 2.2% and 92.3 ± 0.6% at a concentration of 10 μmol/L, respectively. The preliminary structure-activity relationship showed that when the 2-position of the benzene ring was substituted by a methyl group, such as compound 5j (2-(Tert-butyl)?4-chloro-5-((5-((2,3-dimethylphenyl)amino)?1,3,4-thiadiazol-2-yl)thio)pyridazin-3(2H)-One), it exhibited good anticancer activity on MGC-803 cells. Besides, introducing fluorine, chlorine, or trifluoromethyl group onto the benzene ring, such as compound 5 m (2-(Tert-butyl)?4-chloro-5-((5-((4-(trifluoromethoxy)phenyl)amino)?1,3,4-thiadiazol-2-yl)thio)pyridazin-3(2H)-One), displayed good anticancer activity on MGC-803 and Bcap-37 cells.

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.

Functionalized Oxoindolin Hydrazine Carbothioamide Derivatives as Highly Potent Inhibitors of Nucleoside Triphosphate Diphosphohydrolases

Ectonucleoside triphosphate diphosphohydrolases (NTPDases) are ectoenzymes that play an important role in the hydrolysis of nucleoside triphosphate and diphosphate to nucleoside monophosphate. NTPDase1, -2, -3 and -8 are the membrane bound members of this enzyme family that are responsible for regulating the levels of nucleotides in extracellular environment. However, the pathophysiological functions of these enzymes are not fully understood due to lack of potent and selective NTPDase inhibitors. Herein, a series of oxoindolin hydrazine carbothioamide derivatives is synthesized and screened for NTPDase inhibitory activity. Four compounds were identified as selective inhibitors of h-NTPDase1 having IC50 values in lower micromolar range, these include compounds 8b (IC50 = 0.29 ± 0.02 μM), 8e (IC50 = 0.15 ± 0.009 μM), 8f (IC50 = 0.24 ± 0.01 μM) and 8l (IC50 = 0.30 ± 0.03 μM). Similarly, compound 8k (IC50 = 0.16 ± 0.01 μM) was found to be a selective h-NTPDase2 inhibitor. In case of h-NTPDase3, most potent inhibitors were compounds 8c (IC50 = 0.19 ± 0.02 μM) and 8m (IC50 = 0.38 ± 0.03 μM). Since NTPDase3 has been reported to be associated with the regulation of insulin secretion, we evaluated our synthesized NTPDase3 inhibitors for their ability to stimulate insulin secretion in isolated mice islets. Promising results were obtained showing that compound 8m potently stimulated insulin secretion without affecting the NTPDase3 gene expression. Molecular docking studies of the most potent compounds were also carried out to rationalize binding site interactions. Hence, these compounds are useful tools to study the role of NTPDase3 in insulin secretion.

Design, synthesis and biological evaluation of novel semicarbazone-selenochroman-4-ones hybrids as potent antifungal agents

A series of novel 2,3-dihydro-4H-1-benzoselenin-4-one (thio)semicarbazone derivatives were designed and synthesized by using molecular hybridization approach. All the target compounds were characterized by HRMS and NMR and evaluated in vitro antifungal activity against five pathogenic strains. In comparison with precursor selenochroman-4-ones, the hybrid molecules in this study showed significant improvement in antifungal activities. Notably, compound B8 showed significant antifungal activity against other strains excluding Aspergillus fumigatus (0.25 μg/mL on Candida albicans, 2 μg/mL on Cryptococcus neoformans, 8 μg/mL on Candida zeylanoides and 2 μg/mL on fluconazole-sensitive strains of Candida albicans). Moreover, compounds B8, B9 and C2 also displayed most potent activities against four fluconazole-resistance strains. Especially the MIC values of the hybrid molecule B8 against fluconazole-resistant strains were in the range of 0.5–2 μg/mL. Therefore, the molecular hybridization approach in this study provided new ideas for the development of antifungal drug.

3-[(E)-(acridin-9′-ylmethylidene)amino]-1-substituted thioureas and their biological activity

This paper describes the synthesis of a novel series of acridine thiosemicarbazones through a two-step reaction between various isothiocyanates and hydrazine followed by treatment with acridin-9-carbaldehyde. The properties of this series of seven new derivatives are studied using NMR and biochemical techniques, and the DNA-binding properties of the compounds are determined using spectrophotometric studies (UV–vis absorption, fluorescence, and circular/linear dichroism) and viscometry. The binding constants K are estimated as being in the range of 2.2 to 7.8?×?104?M??1 and the percentage of hypochromism was found to be 22.11–49.75% (from UV–vis spectral titration). Electrophoretic experiments prove that the novel compounds demonstrate moderate inhibitory effects against Topo I activity at a concentration of 60?×?10??6?M.

Isatin-β-thiosemicarbazones as potent herpes simplex virus inhibitors

A series of isatin-β-thiosemicarbazones have been designed and evaluated for antiviral activity against herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) in a plaque reduction assay. Their cytotoxicity was examined using human rhabdomyosarcoma cells (RD cells). Several derivatives of isatin-β-thiosemicarbazone exhibited significant and selective antiviral activity with low cytotoxicity. It was found that the thiourea group at thiosemicarbazone and the NH functionality at isatin were essential for their antiherpetic activity. The synthesis and structure-activity relationship studies are presented.
