This article presents a detailed comprehensive investigation of the ortho fluoro- and chloro- substituted benzoic acids both, as isolated molecules and in the crystalline phase. Quantum chemical calculations performed within the density functional theory (DFT) formalism are used to investigate the potential energy landscapes of the molecules, taking into special consideration the effects of the interactions between the carboxylic group and the ortho halogen substituents, as well as the nature of these later on the structure and properties of the investigated systems. The structures of the relevant conformers of the molecules are discussed in comparative terms, and used to rationalize experimental data obtained for the compounds in the gas phase and isolated in low-temperature inert matrices. The UV-induced photofragmentation reactions of two of the compounds isolated in cryogenic inert matrices were studied as illustrative cases. The structures of the crystals reported previously in the literature are revisited and discussed also in a comparative basis. Particular emphasis is given to the analysis of the intermolecular interactions in the different crystals, using Hirshfeld surface analysis, the CE-B3LYP energy decomposition model and the HOMA index, and to their correlation with thermodynamic data.

Solvent-free, atom-efficient, and mechanochemically activated reactions have emerged as synthetic strategy for sustainable chemistry. Herein we report a new mechanochemical approach for the amide coupling of carboxylic acids and amines, mediated by combination of (1-cyano-2-ethoxy-2-oxoethylidenaminooxy)-dimethylaminomorpholinocarbenium hexafluorophosphate (COMU) or N,N,N’,N’-tetramethylchloroformamidinium hexa-fluorophosphate (TCFH) and K2HPO4. The method delivers a range of amides in high yields (70-96%) and fast reaction rates. The reaction protocol is mild, keeps stereochemical integrity of the adjacent to carbonyl stereocenters, and streamlines isolation procedure for solid amide products. Minimal waste is generated due to the absence of bulk solvent. We show that K2HPO4 plays a dual role, acting as a base and a precursor of reactive acyl phosphate species. Amide bonds from hindered carboxylic acids and low-nucleophilic amines can be assembled within 90 minutes by using TCFH in combination with K2HPO4 or N-methylimidazole. The developed mechanochemical liquid-assisted amidation protocols were successfully applied to the challenging couplings of all six carboxylate functions of biotin[6]uril macrocycle with phenylalanine methyl ester, resulting in 80% yield of highly pure hexa-amide-biotin[6]uril. In addition, fast and high-yielding synthesis of peptides and versatile amide compounds can be performed in a safe and environmentally benign manner, as verified by green metrics.

This report details a decarboxylative cross-coupling of (hetero)aryl carboxylates with iodoarenes in the presence of a gold catalyst (>25 examples, up to 96% yield). This reaction is site specific, which overcomes prior limitations associated with gold catalyzed oxidative coupling reactions. The reactivity of the (hetero)aryl carboxylate correlates qualitatively to the field effect parameter (F-ortho). Reactions with isolated gold complexes and DFT calculations support a mechanism proceeding through oxidative addition at a gold(I) cation with decarboxylation being viable at either a gold(I) or a silver(I) species.

Our previous work identified isoxazole-based chalcones and their dihydropyrazole derivatives as two important five-membered heterocycles having antitubercular activity. Hence, in the present study, we biologically evaluated 30 compounds, including 15 isoxazole ring-containing chalcones (17-31) and 15 dihydropyrazoles (32-46) derived from these chalcones for their antimicrobial, antioxidant, and anticancer activities. Chalcones exhibited superior antibacterial and antioxidant activities compared to dihydropyrazoles. Among the chalcones, compound 28 showed potent antibacterial (MIC = 1 mu g/mL) and antioxidant activities (IC50 = 5 +/- 1 mu g/mL). Dihydropyrazoles, on the contrary, demonstrated remarkable antifungal and anticancer activities. Compound 46 (IC50 = 2 +/- 1 mu g/mL) showed excellent antifungal activity whereas two other dihydropyrazoles 45 (IC50 = 2 +/- 1 mu g/mL) and 39 (IC50 = 4 +/- 1 mu g/mL) exhibited potential anticancer activity. The compounds were also tested for their toxicity on normal human cell lines (LO2) and were found to be nontoxic. The active compounds that have emerged out of this study are potential lead molecules for the development of novel drugs against infectious diseases, oxidative stress, and cancer.

Triple-negative breast cancer (TNBC) is the most aggressive cancers with a high recurrence rate and rapidly acquired drug resistance among various breast cancer subtypes. There is no specific drug for treatment of TNBC. Discovery of therapeutic agents with unique modes of actions is urgently needed. In this study, a series of seventy parthenolide derivatives was designed, synthesized, and evaluated for their anti-TNBC activities. Compound 7d exhibited the most potent activity against different breast cancer cells with IC50 values ranging from 0.20 mu M to 0.27 mu M, which demonstrated 11.6- to 18.6-fold improvement comparing to that of the parent compound parthenolide with IC50 values of 2.68-4.63 mu M. It is worth to note that 7d was more active than the positive control drug ADR. Moreover, compound 7d could induce apoptosis of SUM-159 cells through mitochondria pathway and cause G1 phase arrest of SUM-159 cells. These findings indicate that compound 7d deserves further studies as a lead compound for ultimate discovery of effective anti-TNBC drug. (C) 2019 Elsevier Masson SAS. All rights reserved.

A series of indolylkojylmethane (IKM) derivatives (1-23) was synthesized using a multicomponent one-pot reaction under solvent-free condition using a heterogeneous catalyst. The synthesized compounds were screened against breast cancer cell lines MDA-MB-231, MCF7, and T47D. The structure-activity relationship revealed that IKM synthesized from aliphatic aldehydes (9-11) were active against all three cell lines and showed IC50 value of 0.15 mu M-3.93 mu M. IKM synthesized from aromatic aldehydes having electron-donating group (1, 5, and 6) specifically inhibited the proliferation of the MDA-MB-231 cell line. The effect of various substituted indoles (12-17) was also studied and observed that compound 14 synthesized from 5-cyanoindole, specifically inhibited T47D cell line proliferation. Replacing indole (1) with nucleophiles (18-23) in IKM decreased the antiproliferative activity. Compound 10 synthesized from kojic acid, indole and octanal was found to be most potent with IC50 values of 0.21, 0.15, and 3.45 mu M against MDA-MB-231, MCF7, and T47D, respectively.

Celecoxib, is a selective cyclooxygenase-2 (COX2) inhibitor with a 1,5-diaryl pyrazole scaffold. Celecoxib has a better safety profile compared to other COX2 inhibitors having side effects of systemic hypertension and thromboembolic complications. This may be partly attributed to an off-target activity involving phosphodiesterase 5 (PDE5) inhibition and the potentiation of NO/cGMP signalling allowing coronary vasodilation and aortic relaxation. Inspired by the structure of celecoxib, we synthesized a chemically diverse series of compounds containing a 1,3,5-trisubstituted pyrazoline scaffold to improve PDE5 inhibitory potency, while eliminating COX2 inhibitory activity. SAR studies for PDE5 inhibition revealed an essential role for a carboxylic acid functionality at the 1-phenyl and the importance of the non-planar pyrazoline core over the planar pyrazole with the 5-phenyl moiety tolerating a range of substituents. These modifications led to new PDE5 inhibitors with approximately 20-fold improved potency to inhibit PDE5 and no COX-2 inhibitory activity compared with celecoxib. PDE isozyme profiling of compound 11 revealed a favorable selectivity profile. These results suggest that trisubstituted pyrazolines provide a promising scaffold for further chemical optimization to identify novel PDE5 inhibitors with potential for less side effects compared with available PDE5 inhibitors used for the treatment of penile erectile dysfunction and pulmonary hypertension.

The beta -barrel structure of green fluorescent protein (GFP) provides a confined environment to enhance its fluorescence efficiency. Inspired by the unique structure of GFP, we reported a self-restricted GFP chromophore analogue which was rationally grafted onto the middle or the terminal of poly(ethylene glycol)-block-poly(N-isopropyl acrylamide) (PEG-b-PNIPAM) via click chemistry to obtain PEG-GA-PNIPAM and PEG-PNIPAM-GA (GA: MeOBDPI). These structures were characterized through NMR, GPC, and FT-IR. By varying the length of PNIPAM and the location of the GFP chromophore, self-assembly behaviour and fluorescence intensity were correspondingly changed. PEG-GA-PNIPAM and PEG-PNIPAM-GA were assembled into nano-sized spherical micelles above the low critical solution temperature (LCST). The size of the micelles increased with the length of the PNIPAM block. These optical properties were carefully evaluated by UV-Vis and fluorescence spectroscopy. The results indicated that increasing the length of the PNIPAM block enhanced the fluorescence in water, and PEG-PNIPAM74-GA has more remarkable fluorescence intensity than PEG-GA-PNIPAM106 in living cells such as MCF-7 cells. Furthermore, the fluorescence behaviour of PEG-PNIPAM74-GA was studied in MCF-7 cells and L929 cells. The result showed that PEG-PNIPAM74-GA was mostly located in the cytoplasm. Compared with the CellTracker T Red CMTPX dye, it could enter into MCF-7 cells and L929 cells more easily in DMEM with 10% FBS. Therefore, PEG-PNIPAM74-GA has potential application prospects for living cell imaging.
