Carbohydrate-Derived Polytriazole Nanoparticles Enhance the Anti-Inflammatory Activity of Cilostazol. ACS OMEGA 2022; 7:44631-44642.

Abstract
Poly(amide-triazole) and poly(ester-triazole) synthesized from d-galactose as a renewable resource were applied for the synthesis of nanoparticles (NPs) by the emulsification/solvent evaporation method. The NPs were characterized as stable, spherical particles, and none of their components, including the stabilizer poly(vinyl alcohol), were cytotoxic for normal rat kidney cells. These NPs proved to be useful for the efficient encapsulation of cilostazol (CLZ), an antiplatelet and vasodilator drug currently used for the treatment of intermittent claudication, which is associated with undesired side-effects. In this context, the nanoencapsulation of CLZ was expected to improve its therapeutic administration. The carbohydrate-derived polymeric NPs were designed taking into account that the triazole rings of the polymer backbone could have attractive interactions with the tetrazole ring of CLZ. The activity of the nanoencapsulated CLZ was measured using a matrix metalloproteinase model in a lipopolysaccharide-induced inflammation system. Interestingly, the encapsulated drug exhibited enhanced anti-inflammatory activity in comparison with the free drug. The results are very promising since the stable, noncytotoxic NP systems efficiently reduced the inflammation response at low CLZ doses. In summary, the NPs were obtained through an innovative methodology that combines a carbohydrate-derived synthetic polymer, designed to interact with the drug, ease of preparation, adequate biological performance, and environmentally friendly production.

Abstract
1,2,3-triazole heterocycles stand out in medicinal chemistry for having great structural diversity and bioactivities. In this study, two series of triazoles were synthesized. One was obtained by the 1,3-dipolar cycloaddition reaction between ethyl cyanoacetate and several phenyl azides forming 1H-1,2,3-triazoles and the other by rearrangement of Dimroth forming and 2H-1,2,3-triazoles. Both series were shown to be active against the epimastigote form of Trypanosoma cruzi. The 1,2,3-triazoles 16d (S.I. between 100 and 200), 17d and 16f (S.I. > 200) were the most active compounds and capable of breaking the plasma membrane of trypomastigotes acting on CYP51 and inhibiting ergosterol synthesis. Candidate 16d exhibited the best and most favorable profile when interacting with CYP51.

Synthesis, in vitro and computational studies of novel glycosyl-1, 2, 3-1H-triazolyl methyl benzamide derivatives as potential α-glucosidase inhibitory activity. Bioorg Chem 2021; 109:104687.

Abstract
A series of novel glycosyl-1,2,3-1H-triazolyl methyl benzamide analogues were synthesized by the unambiguous strategy and evaluated for α-glucosidase inhibitory activity. Glycosyl benzamide exhibited a dose-dependent inhibition of α-glucosidase activity. The In-vitro α-glucosidase inhibition activity results indicated that all the synthesized triazolyl methyl benzamide compounds (IC50 values ranging from 25.3 ± 0.8 to 118.5 ± 5.3 μM) exhibited more inhibitory activity in comparison with the standard drug acarbose (IC50 = 750.0 ± 12.5 μM). Among all, the 3 deacetylated glycosyl methyl benzamide derivatives (4c, 4d and 4f) showed promising α-glucosidase enzyme inhibitory activities with IC50 value 25.3 ± 0.8, 26.1 ± 1.5 and 30.6 ± 2.1 respectively. Furthermore, these compounds were subjected to molecular docking and molecular dynamics simulation studies. The molecular docking studies were performed between (PDB ID: 3A4A) target protein and these synthesized molecules. The compounds displayed good docking energies in the range of -7.5 to -7.8 Kcal/mol. This work could be used as an initial approach in identifying potential novel molecules with the promising activity of type-2 diabetes mellitus.

Abstract
An efficient three-step synthesis of a new heterocyclic system is described wherein the 2H-bis([1,2,3]triazolo)[5,1-a:4',5'-c]isoquinoline ring system is elaborated using a simple synthetic strategy. The approach permits the preparation of target compounds in high yields using readily available arylhydrazines and o-alkynylbenzaldehydes as starting materials. The photophysical properties of the prepared heterocycles were studied to demonstrate that the prepared compounds are attractive blue-emitting fluorophores, exhibiting quantum yields up to 98% and Stokes shifts up to 67 nm. A strong effect of the steric hindrance on the absorption and emission spectra was revealed.

Abstract
Efficient synthesis of 2,5-diaryl substituted 4-azido-1,2,3-triazoles by the reaction of sodium azide with dichlorosubstituted diazadienes was demonstrated. The optical properties of the prepared azidotriazoles were studied to reveal a luminescence maximum in the 360-420 nm region. To improve the luminescence quantum yields a family of 4-azido-1,2,3-triazoles bearing ortho-propargyloxy substituents in the 5 position was prepared. Subsequent intramolecular thermal cyclization permits to construct additional triazole fragment and obtain unique benzoxazocine derivatives condensed with two triazole rings. This new family of condensed heterocycles has a flattened heterocyclic system structure to provide more conjugation of the 5-aryl fragment with the triazole core. As a result, a new type of UV/"blue light-emitting" materials with better photophysical properties was obtained.

Abstract
The reactions of thioamides with azides in water were studied. It was reliably shown that the reaction of 2-cyanothioacetamides 1 with various types of azides 2 in water in the presence of alkali presents an efficient, general, one-step, atom-economic, and eco-friendly method for the synthesis of 1,2,3-thiadiazol-4-carbimidamides 5 and 1,2,3-triazole-4-carbothioamides 4. This method can be extended to the one-pot reaction of sulfonyl chlorides and 6-chloropyrimidines 2'o with sodium azide, leading to final products in higher yields, that is, avoiding the isolation of unsafe sulfonyl azides. The method was furthermore applied to the reaction of N,N'-bis-(2-cyanothiocarbonyl)pyrazine 1h with sulfonyl azides to afford bicyclic 1,2,3-thiadiazoles 8 and 1,2,3-triazoles 9 connected via a 1,1'-piperazinyl linker. 2-Cyanothioacetamides 1 were also shown to react with aromatic azides in water in the presence of alkali to afford 1-aryl-5-amino-1,2,3-triazole-4-carbothioamides 11. In contrast to aromatic azides and similarly to sulfonyl azides, 6-azidopyrimidine-2,4-diones 2o-q react with cyanothioacetamides to form N-pyrimidin-6-yl-5-dialkylamino-1,2,3-thiadiazole-4-N-l-carbimidamides 12. A mechanism was proposed to rationalize the role of water in changing the reactivity of azides toward 2-cyanothioacetamides.

Abstract
The alkylation of the N(2)-bound ruthenium triazolate [Ru]N3C2HCO2Et (2, [Ru] = (η5-C5H5)(dppe)Ru, dppe = Ph2PCH2CH2PPh2) with benzylbromides is reported. The regiospecific alkylation of 2, which results from the [3 + 2] cycloaddition of ethyl propiolate with [Ru]-N3 (1), gives a series of cationic N(1)-bound N(3)-alkylated-4-ethoxycarbonyl triazolato complexes {[Ru]N3(CH2R)C2HCO2Et}[Br] (3a, R = 4-CH2Br-C6H4; 3b, R = 3,5-(CH2Br)2-C6H3; 3c, R = 2,6-F2-C6H3; 3d, R = 4-CN-C6H4) and the subsequent cleavage of the Ru-N bond of 3a-3d gives N(1)-alkylated-5-ethoxycarbonyl triazoles N3(CH2R)C2HCO2Et (4a-4d) and [Ru]-Br, which, on reacting with sodium azide, would afford [Ru]-N3 (1) thus forming a reaction cycle. The treatment of {[Ru]N3(CH2C6F5)C2HCO2Et}[Br] (3e) with sodium azide in refluxing ethanol gives the free triazole N3(CH2C6F5)C2HCO2Et (4e) and 1. The treatment of 2 with an equivalent of 3a affords a dinuclear bis(triazolato) complex {α,α'-bis([Ru]N3C2HCO2Et)-p-xylene}[Br]2 (5) and an organic bis(triazole) complex α,α'-bis(N3C2HCO2Et)-p-xylene (6). The treatment of 2 with CF3COOH in CHCl3 at room temperature affords a mixture of N(2)-bound 1H- and 3H-4-ethoxycarbonyl triazolato complexes {[Ru]N3HC2HCO2Et}[CF3COO] (1H-7) and (3H-7) in a ratio of 5 : 2. The structures of 4e, 5 and 1H-7 were confirmed by single-crystal X-ray diffraction analysis.

Abstract
A convenient synthesis of 2-aryl-2,4-dihydro-5H-[1,2,3]triazolo[4,5-d]pyrimidin-5-ones (DTPs) from 3,3-diamino-2-(arylazo)acrylonitriles through a versatile and readily accessible two-step procedure is described. Density functional theory (DFT) calculations were performed to explain the selectivity of the heterocyclization step, which predominantly afforded 6-amino-5-(arylazo)pyrimidin-2(1H)-thiones in chloroform or ethanol, and 2,3-dihydro-1,2,4-triazines in toluene or DMF. Novel 2-aryl-2,4-dihydro-5H-[1,2,3]triazolo[4,5-d]pyrimidin-5-ones were obtained in good yields and showed absorption in the ultraviolet region and good emission in the blue region. The photophysical properties of DTPs were better than those cited in select literature examples of 8-azapurines. Owing to the facile synthesis and good photophysical characteristics in an aqueous medium, the new DTPs should have potential applications as organic fluorophores in fluorescence imaging and materials science.

Abstract
Novel oxazolidin-2-one-linked 1,2,3-triazole derivatives (4a-k) were synthesized by straightforward and versatile azide-enolate (3 + 2) cycloaddition. The series of compounds was screened for antifungal activity against four filamentous fungi as well as six yeast species of Candida spp. According to their efficiency and breadth of scope, they can be ordered as 4k > 4d > 4h > 4a, especially in relation to the activity displayed against Candida glabrata ATCC-34138, Trichosporon cutaneum ATCC-28592 and Mucor hiemalis ATCC-8690, i.e. compounds 4d, 4h and 4k showed excellent activity against C. glabrata (MIC 0.12, 0.25 and 0.12 μg mL-1, respectively), better than that of itraconazole (MIC 1 μg ml-1). The activity of compound 4d (MIC = 2 μg mL-1) was higher than that observed for the standard antifungal drug (MIC = 8 μg mL-1) against Trichosporon cutaneum, while compound 4k displayed an excellent antimycotic activity against Mucor hiemalis (MIC = 2 μg mL-1vs. 4 μg mL-1 for itraconazole). In addition, we describe herein a novel mild and eco-friendly synthetic protocol for obtaining β-ketosulfones (adducts to afford compounds 4a-k) from α-brominated carbonyls in an aqueous nanomicellar medium at room temperature.
