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, 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] .

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 properties of novel nitrogen- and oxygen-enriched dicationic 3,4-diaminotriazolium salts as attractive energetic materials

The incorporation of both fuel and oxidizer properties into a single molecule to effectively improve the oxygen balance of energetic compounds has become one of the most acceptable strategies for the design of modern high-energy-density materials (HEDMs). To identify more powerful and less sensitive HEDMs with favorable oxygen balance, novel nitrogen- and oxygen-enriched dicationic 3,4-diaminotriazolium salts were prepared via the quaternization of 3,4-diamino-triazole with 4,4′-bis(nitramino)azofurazan and 4,4′-bis(nitramino)azoxyfurazan, and then fully characterized. These compounds exhibited favorable thermal stabilities with decomposition temperatures up to 216 degrees C, high densities over 1.82 g.cm(-3) as well as acceptable sensitivities. In addition, the two-dimensional fingerprint spectra based on Hirshfeld surface analysis were adopted to illustrate structure-property relationships. Based on the combination of experimentally determined densities and heats of formation calculated with Gaussian 03, the energetic properties were determined using the EXPLO5 v6.02 program. The newly synthesized ionic salts displayed excellent detonation properties (V-d, 9115-9220 m.s(-1); P, 33.9-35.4 GPa), comparable to those of 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX), thus highlighting their potential in energetic material applications.

A simple and efficient strategy for constructing nitrogen-rich isomeric salts and cocrystal through pK(a) calculation

Nitrogen-rich energetic salts and cocrystal have attracted considerable attention in recent years. To assess the formation of cocrystal or salt, acid dissociation constant (pK(a)) values of the isomeric co-formers were calculated in this work and significant differences were observed. Two salts and one cocrystal based on H2BT (1H, 1’H-5,5′-bitetrazole), DATr (4,5-diamino-4H-1,2,4-triazole), 1MAT (1-methyl-5-aminotetrazole) and 2MAT (2-methyl-5-aminotetrazole) were synthesized, which corresponding to the different pK(a) values of three isomeric coformers. Single crystal structure analysis reveals that all compounds are formed by layered stacking structure with pi-pi stacking and rich hydrogen bonds, resulting in the insensitivity towards impact and friction (impact sensitivity > 40 J, friction sensitivity > 360 N). To the best of our knowledge, it is the first time to report the cocrystal of H2BT. The study results provide a utility method to seek for suitable coformers and design energetic cocrystal through the calculation of pK(a). (C) 2020 Elsevier B.V. All rights reserved.

Multifaceted activity of polyciclic MDR revertant agents in drug-resistant leukemic cells: Role of the spacer

A small library of derivatives carrying a polycyclic scaffold recently identified by us as a new privileged structure in medicinal chemistry was designed and synthesized, aiming at obtaining potent MDR reverting agents also endowed with antitumor properties. In particular, as a follow-up of our previous studies, attention was focused on the role of the spacer connecting the polycyclic core with a properly selected nitrogen-containing group. A relevant increase in reverting potency was observed, going from the previously employed but-2-ynyl- to a pent-3-ynylamino moiety, as in compounds 3d and 3e, while the introduction of a triazole ring proved to differently impact on the activity of the compounds. The docking results supported the data obtained by biological tests, showing, for the most active compounds, the ability to establish specific bonds with P-glycoprotein. Moreover, a multifaceted anticancer profile and dual in vitro activity was observed for all compounds, showing both revertant and antitumor effects on leukemic cells. In this respect, 3c emerged as a triple-target agent, endowed with a relevant reverting potency, a considerable antiproliferative activity and a collateral sensitivity profile.

Synthesis, antioxidant and anti-tyrosinase activity of 1,2,4-triazole hydrazones as antibrowning agents

A series of 1,2,4-triazole hydrazones (1-16) were synthesized, and their inhibitory activities and mechanisms on tyrosinase were investigated by ultraviolet spectrophotometry, fluorescence quenching, molecular docking study, etc. Most of compounds possessed potent tyrosinase inhibitory activity. Thereinto, compound 9 presented the superior activity with IC50 of 0.9 mu M, which was markedly lower than the standard kojic acid (IC50 = 64.1 mu M). Compound 9 not only interacted with copper ions in the active center of the enzyme but also bound to the enzyme-substrate complex, indicating that it was a competitive-noncompetitive mixed inhibitor. Additionally, it also displayed potent DPPH scavenging activity. Antibrowning test showed that compound 9 effectively reduced the enzymatic browning of fresh-cut potatoes. Furthermore, compound 9 exhibited low cytotoxic activity against human normal cell line with IC50 of 49.9 mu M. Overall, the present study suggests that these compounds may serve as lead molecules for developing novel antibrowning agents in food industry.
