Synthesis, characterization, in vitro biological and computational evaluation of 5-benzyl-4-(benzylideneamino)-2H-1,2,4-triazole-3(4H)-thiones

Triazoles and their heterocyclic analogues are nitrogen-rich versatile pharmacophores easily synthesized and converted to a range of biologically relevant heterocycles. In this context, the present research reports the synthesis, characterization, in vitro antioxidant, cytotoxic and alpha-glucosidase inhibitory potential of 4-amino-5-benzyl-2H-1,2,4-triazol-3(4H)-thione (3) and 5-benzyl-4-(benzylideneamino)-2H-1,2,4-triazole-3(4H)-thiones 5(a-g). Consequently, the percent DPPH free radical scavenging ability was found to be in the decreasing order of 5 g > 5e > 3 > 5d > 5b > 5c > 5a > 5f. The most potent derivatives (5 g), (5e) and (3) showed significant dose-dependent scavenging ability with IC50 values of 61.22, 74.06 and 94.87 mu g/ml, respectively. The antioxidant derivatives were screened in brine shrimp lethality as well as protein kinase inhibitory assay to unveil their toxic nature. The percent mortality was found to be decreasing in the order of 5b > 5f > 3 > 5a > 5 g > 5d > 5e > 5c at 200 mu g/ml in brine shrimp lethality assay. Accordingly, three derivatives (5b), (3) and (5f) showed significant percent mortality with LC50 values of 25.88, 32.94 and 34.87 mu g/ml, respectively. Similarly, in protein kinase inhibitory assay, maximum inhibitory potential was observed for the derivatives (5 g), (3) and (5e) with MIC values of 50 mu g/disc in each case. Likewise, in alpha-glucosidase inhibition assay, the screened derivatives (3) and (5e) showed notable percent alpha-glucosidase inhibition (66.78 and 55.15%) with IC50 value of 36.11 mu g/ml and 60.33 mu g/ml, respectively. Molecular docking studies of the screened derivatives were performed in order to assess their binding potential and mechanism of their binding with alpha-glucosidase, alpha-kinase and beta-kinase enzymes. Docking simulation revealed that the molecules stabilize themselves inside the active site by establishing non-covalent interactions with critical residues. Noteworthy were the derivatives (3) and (5e) which anchored themselves through various significant electrostatic interactions with the critical residues. [GRAPHICS] .

Investigation of the Reactivity of 1-Azido-3-iodobicyclo[1.1.1]pentane under Click Reaction Conditions

The bicyclo[1.1.1]pentane (BCP) unit is under scrutiny as a bioisostere in drug molecules. We employed methodologies for the synthesis of different BCP triazole building blocks from one precursor, 1-azido-3-iodobicyclo[1.1.1]pentane, by click reactions and integrated cycloaddition-Sonogashira coupling reactions. Thereby, we accessed 1,4-disubstituted triazoles, 5-iodo-1,4,5-trisubstituted triazoles, and 5-alkynylated 1,4,5-trisubstituted triazoles. This gives entry to the synthesis of multiply substituted BCP triazoles on either a modular or a one-pot basis. These methodologies were further utilized for appending porphyrin moieties onto the BCP core.

Synthesis of novel 1,2,3 triazole derivatives and assessment of their potential cholinesterases, glutathione S-transferase enzymes inhibitory properties: An in vitro and in silico study

In this study, new 1,2,3-triazole derivatives containing chalcone core (1-7) were synthesized. Obtained compounds were characterized by IR, H-1 NMR, C-13 NMR, and mass studies. Characterized compounds (1-7) inhibitory effects were tested against the glutathione S-transferase (GST), acetylcholinesterase (AChE), and Butyrylcholinesterase (BChE). Their K-i values were in the range of 5.88-11.13 mu M on AChE, 5.08-15.12 mu M on BChE, and 9.82-13.22 mu M on GST. Remarkable inhibitory effects were obtained against three tested metabolic enzymes. Also, binding scores of the best-inhibitors against AChE, BChE, and GST enzymes were detected as -9.969 kcal/mol, -10.672 kcal/mol, and -8.832 kcal/mol, respectively. Isoindoline-1,3-dione and benzothiophene moieties played a critical role in the inhibition of AChE and BChE enzymes, respectively. Phenylene and triazole moieties had the most important interactions for inhibition of the GST enzyme. Therefore, in vivo and in silico results indicated that these compounds can be considered in drug design processes for the treatment of some diseases including Alzheimer’s disease (AD), leukemia, and some type of cancer.

Intracellular Mutual Promotion of Redox Homeostasis Regulation and Iron Metabolism Disruption for Enduring Chemodynamic Therapy

Intracellular redox homeostasis and the iron metabolism system in tumor cells are closely associated with the limited efficacy of chemodynamic therapy (CDT). Despite extensive attempts, maintaining high levels of intracellular catalysts (free iron) and reactants (H2O2) while decreasing the content of reactive oxygen species (ROS) scavengers (especially glutathione (GSH)) for enduring CDT still remains great challenges. Herein, S-S bond-rich dendritic mesoporous organic silica nanoparticles (DMON) are utilized as GSH-depleting agents. After co-loading Fe-0 and a catalase inhibitor (3-amino-1,2,4-triazole (AT)), a novel biodegradable nanocarrier is constructed as DMON@Fe-0/AT. In the mildly acidic tumor microenvironment, on-demand ferrous ions and AT are intelligently released. AT suppresses the activity of catalase for H2O2 hoarding, and the exposed DMON weakens ROS scavenging systems by persistently depleting intracellular GSH. The highly efficient center dot OH production by DMON@Fe-0/AT can effectively attack mitochondria and downregulate the expression of ferroportin 1, which can disrupt the cellular iron metabolism system, leading to the desired retention of iron in the cytoplasm. More importantly, DMON@Fe-0/AT exhibits a much more efficient CDT killing effect on 4T1 tumor cells than plain Fe-0 nanoparticles, benefiting from their synergistic redox regulation and iron metabolism disruption. Overall, the as-prepared intelligent, degradable DMON@Fe-0/AT provides an innovative strategy for enduring CDT.

Theoretical insights into the synthesis reaction mechanism of 1,2,3-triazole based on sakai reaction

Sakai reaction is an important method to synthetize 1,2,3-triazole by the addition of alpha, alpha-dichlorotosylhydrazones and amines. However, the difficulty of introducing the 1,2,3-triazole ring is often affected by the type of amine reagent. More calculation results and detailed mechanisms are used to screen which amine is more suitable for the Sakai reaction. In this study, the DFT calculations were carried out to study the reaction mechanism of Sakai reaction. Depending on the type of amines, two different paths for Sakai reaction were revealed by our calculations. For the triazolamine, an H atom must transfer from the amines to the diazine synchronously when the new C-N bond is formed. The transformation from trans- to cis- is necessary for the intermediate vinyldiazine. For aniline, the amine molecule can combine with trans-vinyldiazine directly without an H transfer due to the formation of a structure that is similar to NH4+ ion. (C) 2020 Elsevier Ltd.

Synthesis and biological evaluation of heterocyclic 1,2,4-triazole scaffolds as promising pharmacological agents

Background Triazole is an important heterocyclic moiety that occupies a unique position in heterocyclic chemistry, due to its large number of biological activities. It exists in two isomeric forms i.e. 1,2,4-triazole and 1,2,3-triazole and is used as core molecule for the design and synthesis of many medicinal compounds. 1,2,4-Triazole possess broad spectrum of therapeutically interesting drug candidates such as analgesic, antiseptic, antimicrobial, antioxidant, anti-urease, anti-inflammatory, diuretics, anticancer, anticonvulsant, antidiabetic and antimigraine agents. Methods The structures of all synthesized compounds were characterized by physicochemical properties and spectral means (IR and NMR). The synthesized compounds were evaluated for their in vitro antimicrobial activity against Gram-positive (B. subtilis), Gram-negative (P. aeruginosa and E. coli) bacterial and fungal (C. albicans and A. niger) strains by tube dilution method using ciprofloxacin, amoxicillin and fluconazole as standards. In-vitro antioxidant and anti-urease screening was done by DPPH assay and indophenol method, respectively. The in-vitro anticancer evaluation was carried out against MCF-7 and HCT116 cancer cell lines using 5-FU as standards. Results, discussion and conclusion The biological screening results reveal that the compounds T-5 (MICBS, EC = 24.7 mu M, MICPA, (CA) = 12.3 mu M) and T-17 (MICAN = 27.1 mu M) exhibited potent antimicrobial activity as comparable to standards ciprofloxacin, amoxicillin (MICCipro = 18.1 mu M, MICAmo = 17.1 mu M) and fluconazole (MICFlu = 20.4 mu M), respectively. The antioxidant evaluation showed that compounds T-2 (IC50 = 34.83 mu g/ml) and T-3 (IC50 = 34.38 mu g/ml) showed significant antioxidant activity and comparable to ascorbic acid (IC50 = 35.44 mu g/ml). Compounds T-3 (IC50 = 54.01 mu g/ml) was the most potent urease inhibitor amongst the synthesized compounds and compared to standard thiourea (IC50 = 54.25 mu g/ml). The most potent anticancer activity was shown by compounds T-2 (IC50 = 3.84 mu M) and T-7 (IC50 = 3.25 mu M) against HCT116 cell lines as compared to standard 5-FU (IC50 = 25.36 mu M).
