Optimization of 1,3-disubstituted urea-based inhibitors of Zika virus infection

Zika virus (ZIKV) has become a public health concern worldwide due to its association with congenital abnormalities and neurological diseases. To date, no effective vaccines or antiviral drugs have been approved for the treatment of ZIKV infection, and ne

Synthesis, characterization and biological evaluation of thiadiazole amide derivatives as nucleoside triphosphate diphosphohydrolases (NTPDases) inhibitors

Importance of extracellular nucleotides is widely understood. These nucleotides act as ligand for P2X and P2Y receptors and modulate a variety of biological functions. However, their extracellular concentration is maintained by a chain of enzymes termed as ecto-nucleotidases. Amongst them, nucleoside triphosphate diphosphohydrolases (NTPDases) is an important enzyme family responsible for the dephosphorylation of these nucleotides. Overexpression of NTPDases leads to many pathological conditions such as cancer and thrombosis. So far, only a few NTPDase inhibitors have been reported. Considering this scarcity of (NTPDase) inhibitors, a number of thiadiazole amide derivatives were synthesized and screened against human (h)-NTPDases. Several compounds showed promising inhibitory activity; compound 5a (IC50 (μM); 0.05 ± 0.008) and 5g (IC50 (μM); 0.04 ± 0.006) appeared to be the most distinguished molecules corresponding to h-NTPDase1 and -2. However, h-NTPDase3 was the least susceptible isozyme and only three compounds (5d, 5e, 5j) strongly inhibited h-NTPDase3. Interestingly, compound 5e was recognized as the most active compound that showed dual inhibition against h-NTPDase3 as well as against h-NTPDase8. For better comprehension of binding mode of these inhibitors, most potent inhibitors were docked with their respective isozyme.

Synthesis and Bioactivity Evaluation of Novel Thiochroman-4-One Derivatives Incorporating Carboxamide and 1, 3, 4-Thiadiazole Thioether Moieties

A series of novel thiochroman-4-one derivatives incorporating carboxamide and 1, 3, 4-thiadiazole thioether moieties were synthesized. Bioassay results indicated that the EC50 values of compound 6-chloro-N-(5-(methylthio)-1, 3, 4-thiadiazol-2-yl)-4-oxothiochromane-2-carboxamide (5a) against Xanthomonas oryzae pv. Oryzae (Xoo) and Xanthomonas axonopodis pv. Citri (Xac) were 24 and 30 μg/mL, respectively, which were even better than those of bismerthiazol and thiadiazole copper. Meanwhile, compound 6-methyl-4-oxo-N-(5-(propylthio)-1, 3, 4-thiadiazol-2-yl)thiochromane-2-carboxamide (5m) showed a better antifungal activity against Botrytis cinerea (B. cinerea), with an inhibition rate of 69%, than carbendazim. As far as we know, this is the first report on the antibacterial and antifungal activities of this series of novel thiochroman-4-one derivatives incorporating carboxamide and 1, 3, 4-thiadiazole thioether moieties.

Design and development of 1,3,4-thiadiazole based potent new nano-fungicides

Being the important organic reaction intermediates and biological scaffolds, a series of 2-alkyl/aralkyl/heterocyclyl sulfanyl-5-amino/methyl-1,3,4-thiadiazoles have been synthesized by suitable synthetic route and characterized by analytical and spectral data. The evaluation of these compounds for their bioefficacy against two phyto-pathogenic fungi revealed their fungicidal potency against Rhizoctonia bataticola (ED50 values, 3.9–300.4 μg/mL) and Rhizoctonia solani (ED50 values, 4.2–228.5 μg/mL). To further augment their fungicidal efficacy, the potent five fungicidal compounds were nano-sized. The protocol for preparing 1,3,4-thiadiazole based nano-fungicide employing polyethylene glycol was developed and standardized. Characterization of nano-forms of 1,3,4-thiadiazole derivatives by particle size analyzer and electron microscopy (TEM) techniques confirmed the 100 nm average particle sizes of all nano-fungicides. The 2–4 times higher fungicidal activity was observed with nano-forms than the corresponding conventional sized 1,3,4-thiadiazole derivatives against phytopathogenic fungi, namely, Rhizoctonia solani and R. bataticola.

Design, synthesis and anti-bacterial evaluation of novel 1,3,4-thiadiazole derivatives bearing a semicarbazone moiety

Novel 1,3,4-thiadiazole derivatives bearing a semicarbazone moiety were prepared and evaluated for their anti-bacterial activities against Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas axonopodis pv. citri (Xac) by performing a turbidimetre test. The products were structurally characterised by IR, 1H NMR, 13C NMR, 19F NMR and HRMS. Anti-bacterial testing showed that most of the evaluated compounds (6a-6s) exhibited excellent activity (≥74.19%) against Xoo at a concentration of 200?μg/mL, with 50% effective concentration (EC50) values ranging from 12.21 to 67.20?μg/mL, which were superior to the commercial antibacterial agent bismerthiazol (92.23?μg/mL). Among them, compound 2-((2-chloro-1H-indol-3-yl)methylene)-N-(5-((2-chlorobenzyl)thio)-1,3,4-thiadiazol-2-yl)hydrazine-1-carboxamide (6b) demonstrated good inhibitory activity against Xac (89.46% at 200?μg/mL) and Xoo (EC50 = 18.28?μg/mL); compound 2-((2-chloro-1H-indol-3-yl)methylene)-N-(5-((4-methoxybenzyl)thio)-1,3,4-thiadiazol-2-yl)hydrazine-1-carboxamide (6g) displayed excellent activity against Xoo with EC50 value of 12.21?μg/mL.

Synthesis and in vitro evaluation of west nile virus protease inhibitors based on the 1,3,4,5-tetrasubstituted 1H-Pyrrol-2(5H)-one scaffold

West Nile virus (WNV), a member of the Flaviviridae family, is a mosquito-borne pathogen that causes a large number of human infections each year. There are currently no vaccines or antiviral therapies available for human use against WNV. Therefore, efforts to develop new chemotherapeutics against this virus are highly desired. In this study, a WNV NS2B-NS3 protease inhibitor with a 1,3,4,5-tetrasubstituted 1H-pyrrol-2(5H)-one scaffold was identified by screening a small library of nonpeptidic compounds. Optimization of this initial hit by the synthesis and screening of a focused library of compounds with this scaffold led to the identification of a novel uncompetitive inhibitor ((-)-1a16, IC50=2.2±0.7μM) of the WNV NS2B-NS3 protease. Molecular docking of the chiral compound onto the WNV protease indicates that the Renantiomer of 1a16 interferes with the productive interactions between the NS2B cofactor and the NS3 protease domain and is thus the preferred isomer for inhibition of the WNV NS2B-NS3 protease.

Furthermore, 5e induced tumor cell apoptosis, which was accompanied by lower Bcl-2 expression, but with higher Bax and caspase 3 expression activities in cancer cells.
