Novel 1-Triazolylpyranopyrazoles as Highly Potent Anticancer Agents Obtained via MW-Assisted Synthesis

A series of novel 1-triazolylpyranopyrazole derivatives has been designed and synthesized using microwave irradiation, with the purpose of obtaining repositioned pharmaceutics. The newly synthesized 1-triazolylpyranopyrazoles (7 a-7 n), along with their precursor alkyne (5), have been screened for their in-vitro anti-tumor activity against Hep3B and HEK cell lines. The majority of triazolylpyranopyrazoles elicited outstanding anti-cancer activity on Hep3B cell lines even at concentrations as low as 25 mu g/mL. Further, molecular docking of these active compounds against Topoisomerase IIa substantiated a plausible target site for the compounds inhibiting Hep3B cells effectively. The biological assay results for the triazolylpyranopyrazole even surpassed the activity of the reference drug i. e. Doxorubicin, thereby appearing to be potent anticancer agents.

Synthesis of co-crystals of anti-cancer nandrolone as a potential leads towards treatment of cancer

Co-crystals are emerging as members of supramolecular family having particular practical and fundamental significance for chemists, crystallographers, pharmaceutical scientists, and theoreticians. The presented study is focused to synthesize anti-cancer co-crystals of commercially available nandrolone (1), a synthetic anabolic-androgenic steroidal drug. Co-crystallization is done using economical and green grinding and reflux methods to obtain nandrolone (Nan): salicylic acid (Sal) and nandrolone (Nan): 3-amino-1,2,4-triazole (Triz) co-crystals, in 2:1 and 1:1 stoichiometric ratios, respectively. The structural analysis and characterization were carried out using single-crystal X-ray diffraction, and vibrational spectroscopy. Nandrolone (1) crystallizes in monoclinic P2(1) space group, while the co-crystal-I (Nan:Sal) and co-crystal-II (Nan:Triz), co-crystallized in the orthorhombic P2(1)2(1)2(1) space group. The intermolecular hydrogen bonds O-H center dot center dot center dot O, C-H center dot center dot center dot O, N-H center dot center dot center dot O, O-H center dot center dot center dot N, and N-H center dot center dot center dot N between the active pharmaceutical ingredient (nandrolone) and co-formers (salicylic acid, and 3-amino-1,2,4-triazole) stabilize the structures of cocrystals. In vibrational spectroscopy of co-crystal-I (Nan:Sal), the blue shifts in stretching frequencies of hydroxyl group from 3417.9 cm(-1) to 3427.8 cm(-1) further supported the hydrogen bond interactions between API and co-former. Similarly, in co-crystal-II (Nan:Triz) the NH2 stretching frequency from 3331.4- 3413.4 cm(-1) to 3312.7 cm(-1), supported the interaction of NH2 with API via intermolecular interaction. Nandrolone (1) and both co-crystals were found to be non-cytotoxic against 3T3 normal fibroblast cell line. Nandrolone (IC50 = 1.0 0.1 mu M), co-crystal-I (Nan:Sal) (IC50 = 1.6 +/- 0.3 mu M) and-II (Nan:Triz) (IC50 = 1.8 +/- 0.1 mu M) showed anti-cancer potential against cervical cancer HeLa cell line. While doxorubicin (IC50 = 1.2 +/- 0.2 mu M) was used as standard tested compound. SYNOPSIS Two new non-cytotoxic co-crystals of synthetic anabolic-androgenic steroidal drug nandrolone (Nan) with pharmaceutically acceptable salicylic acid (Sal), and triazole (Triz) were synthesized and their structures were elucidated using single-crystal X-ray diffraction, and vibrational spectroscopy. Quantitative analysis of -OH and -NH2 intermolecular interactions between API and co-former by Hirshfeld surface analysis further supported the role of various functionalities towards the stability of co-crystals. Both co-crystals were found to be non-cytotoxic against 3T3 normal fibroblast cell line. Co-crystal-I (Nan:Sal) and co-crystal-II (Nan:Triz) were found to be selectively active against HeLa cancer cell line (IC50 = 1.6 +/- 0.3 mu M), (IC50 = 1.8 +/- 0.1 mu M). (c) 2020 Elsevier B.V.

1,2,3-Triazoles as leaving groups in SN(A)r-Arbuzov reactions: synthesis of C6-phosphonated purine derivatives

A new method for C-N bond transformations into C-P bonds was developed using 1,2,3-triazoles as leaving groups in SNAr-Arbuzov reactions. A series of C6-phosphonated 2-triazolylpurine derivatives was synthesized for the first time, with the isolated yields reaching up to 82% in the C-P-bond-forming event. The SNAr-Arbuzov reaction of 2,6-bistriazolylpurines follows the general regioselectivity pattern of the C6-position being more reactive towards substitution, which was unambiguously proved by X-ray analysis of diethyl (9-heptyl-2-(4-phenyl-1H-1,2,3-triazol-1-yl)-9H-purin-6-yl)phosphonate.

Structural characterization and QSAR modeling of 1,2,4-triazole derivatives as alpha-glucosidase inhibitors

In order to identify potential new drugs that could be useful in preventing and treating diabetes, we benchmarked several exchange-correlation functionals and ab initio methods to accurately describe the structural, electronic and vibrational properties of 1,2,4-triazole (Tz) and 1,2,4-triazolone (TzO). This theoretical approach was employed to develop a QSAR model to correlate the quantum chemical descriptors of 1,2,4-triazolone derivatives with their antidiabetic activity. The best statistically significant correlations between the biological activity and the descriptors were generated after a multiple linear regression (MLR) analysis. A QSAR model was successfully developed and a good correlation between the experimental and predicted activity values was described.

Neutral Chiral Tetrakis-Iodo-Triazole Halogen-Bond Donor for Chiral Recognition and Enantioselective Catalysis

Halogen bonding represents a powerful tool in the field of noncovalent interactions. However, applications in enantioselective recognition and catalysis remain almost nonexistent, due in part to the distinct features of halogen bonds, including long covalent and noncovalent bond distances and high directionality. Herein, this work presents a novel chiral tetrakis-iodo-triazole structure as a neutral halogen bond donor for both chiral anion-recognition and enantioinduction in ion-pair organocatalysis. NMR-titration studies revealed significant differences in anion affinity between the halogen bonding receptor and its hydrogen bonding parent. Selective recognition of chiral dicarboxylates and asymmetric induction in a benchmark organocatalytic reaction were demonstrated using the halogen bond donor. Inversions in the absolute sense of chiral recognition, enantioselectivity, and chiroptical properties relative to the related hydrogen donor were observed. Computational modeling suggested that these effects were the result of distinct anion-binding modes for the halogen- versus hydrogen-bond donors.

Effect of Alkyl Side Chains of Polymer Donors on Photovoltaic Performance of All-Polymer Solar Cells

In this manuscript, we investigate the effect of alkyl side chains of polymer donors on photovoltaic performance of all-polymer solar cells (all-PSCs) based on polymer acceptors containing a boron-nitrogen coordination bond (B <- N). We develop three polymer donors, CD-C12, CD-C16, and CD-C20, with 4,8-di(thiophen-2-yl)benzo[1,2-b:4,5-b']dithophen-alt-5,6- difluoro-7-(thiophen-2-yl)-2H-benzo [d][1,2,3]triazole as the main chain and 2-butyloctyl, 2-hexyldecyl, and 2-octyldodecyl as the side chains, respectively. The three polymer donors exhibit similar LUMO/HOMO energy levels and similar absorption spectra. However, they show different aggregation tendency in solution and different solid stacking properties. Among the three polymers, CD-C16 containing medium-length alkyl side chains exhibits the strongest aggregation behavior in solution and much enhanced crystallinity in films. The three polymer donors are blended with a B <- N-based polymer acceptor PBN-14 to prepare all-PSCs. The device of CD-C16 with medium-length alkyl side chains shows small-size phase separation, which leads to a power conversion efficiency (PCE) of up to 9.8%. In comparison, the active layers of CD-C12 and CD-20 show large-scale phase separation and decreased PCEs of the devices. The optimal all-PSC device performance of CD-16 is ascribed to the strong aggregation behavior of polymer backbones in solution and the high crystallinity, which inhibit the oversized crystals of the polymer acceptor and lead to ideal phase separation morphology of the donor/acceptor blend. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.
