Experimental and computational thermochemical study of two fluorobenzazoles: 5-fluoro-2-methylbenzoxazole and 5-fluoro-2-methylbenzothiazole

An energetic study of 5-fluoro-2-methylbenzoxazole (FMBO) and of 5-fluoro-2-methylbenzothiazole (FMBT), in condensed and gaseous states, has been performed using calorimetric techniques and computational calculations. The standard (p?=0.1MPa) molar enthalpies of formation of FMBO and FMBT, in the liquid phase, at T = 298.15 K, were derived from the corresponding standard molar energies of combustion, measured by rotating-bomb combustion calorimetry. At T = 298.15 K, the standard (p?=0.1MPa) molar enthalpy of vaporization, for each compound, was determined, by a direct method, using the vacuum drop microcalorimetric technique. For each compound, from this last value and from the enthalpy of formation of the liquid compounds, the corresponding standard (p?=0.1MPa) enthalpy of formation in the gaseous phase has been calculated. Additionally, the gas-phase standard molar enthalpies of formation of these two compounds were estimated computationally at the G3(MP2)//B3LYP level of theory, as well as their gas-phase basicities and proton affinities.

Acetylshikonin is a novel non-selective cytochrome P450 inhibitor

Acetylshikonin is a biologically active compound with anti-cancer and anti-inflammatory activity, which is isolated from the roots of Lithospermum erythrorhizoma. An inhibitory effect of acetylshikonin against CYP2J2 activity was discovered recently. Based on this result, this study was expanded to evaluate the inhibitory effects of acetylshikonin against nine different cytochrome P450 (P450) isoforms in human liver microsomes (HLMs) using substrate cocktails incubation assay. Acetylshikonin showed a strong inhibitory effect against all P450s tested with IC50 values of 1.4?4.0 mu m. Pre-incubation of acetylshikonin with HLMs and NADPH did not alter the inhibition potency, indicating that acetylshikonin is not a mechanism-based inhibitor. SKF-525A, a widely used non-specific P450 inhibitor, had no inhibitory activity against CYP1A2, 2A6, 2E1 and 2J2, while it showed an inhibitory effect against CYP2B6, CYP2C19 and 2D6 with IC50 values of 2.5, 3.6 and 0.5 mu m, respectively. Our findings indicate that acetylshikonin may be a novel general P450 inhibitor, which could replace SKF-525A.

Synthesis and evaluation of arylpiperazine-reverse amides as biased dopamine D3 receptor ligands

The dopamine D3 receptor (D3R) preferential ligands have been universally adopted as a strategy for the treatment of drug addiction and other neuropsychiatric disorders due to fewer side effects. However, the high sequence homology between D3R and the D2 receptor (D2R) challenges the development of D3R-biased compounds. Herein, we design and synthesize a novel series of reverse amide-piperazine hybrid ligands and evaluate their biological affinities in vitro. Compound 4d was found to be the most potent D3R-selective ligand among these hybrid derivatives. Molecular modeling revealed that extracellular loop 1 (EL1) and loop 2 (EL2) of D3R together likely contribute to D3R selectivity over D2R. In particular, Gly94 in EL1 of D3R may act as a molecular determinant for D3R specificity.

Synthesis, antifungal activities and molecular docking studies of benzoxazole and benzothiazole derivatives

Based on benzoxazole and benzothiazole scaffold as an important pharmacophore, two series of 2-(aryloxymethyl) benzoxazole and benzothiazole derivatives were synthesized and their antifungal effects against eight phytopathogenic fungi were evaluated. Compounds 5a, 5b, 5h, and 5i exhibited significant antifungal activities against most of the pathogens tested. Especially 5a, 5b, 5h, 5i, 5j, and 6h inhibited the growth of F. solani with IC50 of 4.34?17.61 mug/mL, which were stronger than that of the positive control, hymexazol (IC50 of 38.92 mug/mL). 5h was the most potent inhibitor (IC50 of 4.34 mug/mL) against F. Solani, which was about nine times more potent than hymexazol. Most of the test compounds displayed significant antifungal effects against B. cinerea (IC50 of 19.92?77.41 mug/mL), among them, 5a was the best one (IC50 of 19.92 mug/mL). The structure-activity relationships (SARs) were compared and analyzed. The result indicates that the electron-drawing ability and position of the substituents have a significant impact on biological activities. Furthermore, docking studies were carried out on the lipid transfer protein sec14p from S. cerevisiae, and preliminarily verified the antifungal activities. Taken together, these results provide 2-(phenoxymethyl)benzo[d]oxazole as an encouraging framework that could lead to the development of potent novel antifungal agents.

Recognition of Artificial Nucleobases by E. coli Purine Nucleoside Phosphorylase versus its Ser90Ala Mutant in the Synthesis of Base-Modified Nucleosides

A wide range of natural purine analogues was used as probe to assess the mechanism of recognition by the wild-type (WT) E. coli purine nucleoside phosphorylase (PNP) versus its Ser90Ala mutant. The results were analyzed from viewpoint of the role of the Ser90 residue and the structural features of the bases. It was found that the Ser90 residue of the PNP 1) plays an important role in the binding and activation of 8-aza-7-deazapurines in the synthesis of their nucleosides, 2) participates in the binding of alpha-D-pentofuranose-1-phosphates at the catalytic site of the PNP, and 3) catalyzes the dephosphorylation of intermediary formed 2-deoxy-alpha-D-ribofuranose-1-phosphate in the trans-2-deoxyribosylation reaction. 5-Aza-7-deazaguanine manifested excellent substrate activity for both enzymes, 8-amino-7-thiaguanine and 2-aminobenzothiazole showed no substrate activity for both enzymes. On the contrary, the 2-amino derivatives of benzimidazole and benzoxazole are substrates and are converted into the N1- and unusual N2-glycosides, respectively. 9-Deaza-5-iodoxanthine showed moderate inhibitory activity of the WT E. coli PNP, whereas 9-deazaxanthine and its 2?-deoxyriboside are weak inhibitors. How does it work? The substrate and inhibitory properties of a wide range of artificial bases for the wild-type E. coli purine nucleoside phosphorylase (PNP) versus its Ser90Ala mutant were studied to evaluate the mechanism of recognition by PNP and the role of various electronic and structural features in this process. The PNP recognized a broad palette of bases consisting of a number of dissimilar fragments determining its ability to interact with the Asp204 and Ser90 residues (see scheme).

Iron-Catalyzed Arene C-H Amidation Using Functionalized Hydroxyl Amines at Room Temperature

Herein, we report Fe(III)(TPP)Cl as an effective catalyst for promoting arene C-H amidation through intramolecular cyclization of N-tosyloxyarylcarbamate substrates. The reaction proceeds via nitrene (outer sphere pathway) C(sp2)-H insertion to yield benzoxazolones under external-oxidant-free conditions at ambient temperature. The method is operationally simple and scalable with high-functional-group tolerance. Preliminary experimental and computational data indicates involvement of electrophilic aromatic substitution mechanism for this aryl C-H amidation transformation, distinct from operating mechanism reported previously in aryl C-H amination using azide-based substrates.

Azolylthioacetamides as a potent scaffold for the development of metallo-beta-lactamase inhibitors

In an effort to develop new inhibitors of metallo-beta-lactamases (MbetaLs), twenty-eight azolylthioacetamides were synthesized and assayed against MbetaLs. The obtained benzimidazolyl and benzioxazolyl substituted 1?19 specifically inhibited the enzyme ImiS, and 10 was found to be the most potent inhibitor of ImiS with an IC50 value of 15 nM. The nitrobenzimidazolyl substituted 20?28 specifically inhibited NDM-1, with 27 being the most potent inhibitor with an IC50 value of 170 nM. Further studies with 10, 11, and 27 revealed a mixed inhibition mode with competitive and uncompetitive inhibition constants in a similar range as the IC50 values. These inhibitors resulted in a 2?4-fold decrease in imipenem MIC values using E. coli cells producing ImiS or NDM-1. While the source of uncompetitive (possibly allosteric) inhibition remains unclear, docking studies indicate that 10 and 11 may interact orthosterically with Zn2 in the active site of CphA, while 27 could bridge the two Zn(II) ions in the active site of NDM-1 via its nitro group.
