Role of non-conventional hydrogen bonding in controlling regioselectivity for nucleophilic aromatic substitution of 4,6-dinitroisoindoline-1,3-dione with 1,2,3-triazole isomers: a computational studies

The nucleophilic aromatic substitution reactions of 4,6-dinitroisoindoline-1,3-dione with 1,2,3-triazole isomers, i.e., 1H-1,2,3-triazole and 2H-1,2,3-triazole, have been investigated theoretically using DFT/B3LYP calculations employing 6-31G(d,p) basis set in gas phase as well as in solvent phase. The computational studies have supported the formation of transition states via one-step concerted mechanism for the nucleophilic aromatic displacement of nitro groups with 1,2,3-triazoles rather than intermediate formation via two-step addition-elimination mechanism. The amination of 4,6-dinitroisoindoline-1,3-dione with 1,2,3-triazole isomers have revealed regioselectivity of peri-attack despite sterically favorable para-attack. The regioselectivity is attributed to the stabilization of the transition state through intra-molecular hydrogen bond C-H center dot center dot center dot O=C. This work presents the role of C-H bond as an effective hydrogen bond donor. The molecular interactions through hydrogen bonding have been investigated using AIM method. This work shall result in the synthesis of new regioselective 1,2,3-triazole-derived phthalimide compounds possessing potential biological candidature.

Insights into corrosion inhibition mechanism of mild steel in 1 M HCl solution by quinoxaline derivatives: electrochemical, SEM/EDAX, UV-visible, FT-IR and theoretical approaches

Three quinoxaline-based heterocycles namely, 6-methyl-2,3-diphenyl-quinoxaline (Q-CH3), 6-nitro-2,3-diphenylquinoxaline (Q-NO2) and 2,3-diphenylquinoxaline (Q-H) were evaluated as inhibitor for mild steel (MS) in 1 M HCl. Inhibition effectiveness of the Q-H, Q-CH3 and Q-NO2 tested using different computational simulations and experimental methods. Results showed that inhibition effectiveness of Q-H, Q-CH3 and Q-NO2 increases with their concentration. Polarization results showed that Q-H, Q-CH3 and Q-NO2 displayed anodic-type behaviour. Inhibition efficiencies of Q-H, Q-CH3 and Q-NO2 followed the order: 87.6% (Q-NO2) < 90.2% (Q-CH3)< 92.4% (Q-H) for Q-CH3. Presence of both electron withdrawing (-NO2) and donating (-CH3) substituents decrease the inhibition efficiency as compared to the parent compound however in decrease in protection power is more prominent in the presence of -NO2 substituent. Q-H, Q-CH3 and Q-NO2 inhibit corrosion by adsorbing on MS surface and their adsorption mode followed Langmuir adsorption isotherm. Adsorption of Q-H, Q-CH3 and Q-NO2 on metallic surface reinforced with SEM-EDS and UV-visible studies of MS surfaces. Interaction mechanism of QH, Q-CH3 and Q-NO(2 )with MS surface and their mode of adsorption was studies using DFT and MD (MD) simulations, respectively. Negative sign of adsorption energies (E-ads) for Q-H, Q-CH3 and Q-NO2 suggested that they adsorb spontaneously over MS surface. Interested yet?

A luminescent zinc-organic framework as bifunctional chemosensors for detection of nitrobenzene and Fe3+

A luminescent zinc metal-organic framework with uncoordinated triazolate N-donors, namely [Zn (tba)(2)]center dot DMA (1, DMA = N,N-dimethylacetamide), has been successfully synthesized under solvothermal conditions by using a triazolate-carboxylate bifunctional ligand, 4-(1H-1,2,4-triazol-1-yl)ebenzoic acid (Htba). Single-crystal X-ray diffraction analysis reveals that compound 1 displays a 4-fold interpenetrating dia framework with 1D dumbbell-shaped channels. The systematic luminescence experiments reveal that 1 can be potentially used as a fast-response fluorescence sensor for the sensitive detection of nitrobenzene and Fe3+ ion through drastic fluorescence quenching. Moreover, the quenching mechanisms of 1 towards nitrobenzene and Fe3+ were also investigated.

Development of new hetero-steroid hybrids with antiproliferative activity against MCF-7 breast cancer cells

In continuation of our efforts to develop new antiproliferative agents that could be effective and selective in treatment of cancer, we designed and synthesized new hybrid structures containing an arylsulfonamide scaffold linked to a steroidal skeleton through a 1,2,3-triazole ring. Both in vitro cytotoxicity on breast MCF-7 cancer cells and human placental aromatase enzyme (pAROM) inhibition assays were performed on new hybrids. All new hybrids showed marked cytotoxic activity against breast MCF-7 cancer cells (IC50 = 3.56-43.76 mu M) in comparison to staurosporine (IC50 = 4.06 mu M). Tumor selectivity index was higher for some of the new hybrids on normal fibroblast (F-180) cells (TS = 1.5-25) in comparison to staurosporine (TS = 2.5). The p-nitro derivative exhibited the best inhibitory activity on the pAROM with an IC50 of 64.6 ng/cm(3), compared to hybrids unsubstituted derivative, p-bromo derivative, and letrozole (IC50 = 375.14, 269.86, and 132.86 ng/cm(3), respectively). Furthermore, the p-nitro hybrid arrested the cell cycle selectively at the G2/M phase, in addition to inducing both early and late apoptotic processes of breast MCF-7 cancer cells. Molecular docking studies were performed within pAROM to explore the binding modes of the new hybrids. Collectively, the antiproliferative profile of new hybrids indicates how good they are as promising leads for developing tumor-specific cytotoxins, and deserve further studies to optimize their structure and in vivo activity.

Transition of triazole-resistant Aspergillus fumigatus isolates in a Japanese tertiary hospital and subsequent genetic analysis

Objective: To evaluate the annual variation in the frequency of patient-acquired azole-resistant Aspergillus fumigatus (ARAf), and correlate it to the amount of oral triazole prescribed, in Nagasaki, Japan. Methods: A. fumigatus isolates from respiratory specimens collected in the Nagasaki University Hospital (NUH) between 1996 and 2017 were included in the study. The amount of oral triazole prescribed in NUH since 2001 was obtained from the medical ordering system. Mutations in cyp51A, hmg1, and erg6 genes of ARAf were also analysed. Results: From a total of 240 ARAf strains, 12 (5%), 6 (2.5%), 15 (6.25%), and 3 (1.25%) strains were resistant to itraconazole (ITC), voriconazole (VRC), to either ITC or VRC, and both triazoles, respectively. The amount of prescribed VRC increased annually, and was three times as large as that of ITC in 2017. All eleven patients harbouring ITC-resistant strains had a history of prior ITC treatment, while only one of six patients harbouring VRC-resistant strains had a history of prior VRC treatment. cyp51A mutations were recorded in 10 strains; however, tandem repeat mutations of the promoter region of cyp51A were not observed. Several azole-resistant strains had non-cyp51A mutations. Conclusions: The frequency of patient-acquired ARAf is not increasing in Nagasaki, Japan. Furthermore, the prevalence of VRC-induced ARAf was rare despite the remarkable increase in the amount of prescribed VRC. Mutations in genes other than cyp51A should also be considered when ARAf strains are obtained from patients treated with azole antifungals.

Resistance to demethylation inhibitors in Cercospora beticola, a pathogen of sugar beet in Japan, and development of unique cross-resistance patterns

Cercospora beticola Sacc. is the most destructive pathogen of sugar beet (Beta vulgaris L.) and causes Cercospora leaf spot (CLS). Since 1986, fungicides that function as demethylation inhibitors (DMIs) have been used to control CLS in Hokkaido, which is the only area in Japan where sugar beet is grown. Reduced sensitivity of C. beticola to DMI fungicides, based on the half maximal effective concentration (EC50), was first reported in Hokkaido in 1999, however the fungicides continued to be used effectively until 2014. In a field experiment in 2016, we found that the efficacy of difenoconazole against the field population of C. beticola was greatly reduced. We subsequently tested over 600 isolates collected throughout the sugar beet-growing region of Hokkaido and revealed that the mean resistance factor of four DMI fungicides (difenoconazole, fenbuconazole, tebuconazole, and tetraconazole) were high, which indicates that DMI-resistant isolates were distributed throughout the beet cultivation area. Moreover, we identified three types of isolates that have unique cross-resistance patterns between difenoconazole and fenbuconazole, with their EC50 rate (= difenoconazole EC50/ fenbuconazole EC50) converged to 31, 4.0, and 0.40, respectively, which appeared to be affected by the local history of fungicide usage. The F144L substitution in CbCYP51 was only found in the group whose EC50 rate was 0.40. This is the first report of DMI resistance in C. beticola in Japan, and the findings in this study could contribute to our understanding of the mechanism of DMI resistance.
