Pharmacophore modeling, 3D-QSAR, docking study and ADME prediction of acyl 1,3,4-thiadiazole amides and sulfonamides as antitubulin agents

Pharmacophore modeling, molecular docking, and in silico ADME studies have been carried out to determine the binding mode and drug likeliness profile of acyl 1,3,4-thiadiazole amides and sulfonamides as antitubulin agents. A four point pharmacophore model (AAHR.11) was generated using 63 compounds with IC50 values ranging from 3.16 to 505.76 mu M. A statistically significant 3D-QSAR model was generated from the pharmacophore hypothesis. The model had a high correlation coefficient (R-2 = 0.8925), cross validation coefficient (Q(2) = 0.8204) and F value (44.3) at 6 component PLS factor. The results of external validation indicated that the generated QSAR model possessed a high predictive power (R-2 = 0.83). The generated model also passed Tropsha’s test for predictive ability and Y-Randomisation test. The Domain of Applicability (APD) of the model was also successfully defined to ascertain that a given estimation can be considered reliable. Further, the restrictivity of the model was checked with inactive compounds by enrichment studies using the decoy test. In order to evaluate the effectiveness of the docking protocol, co-crystallized ligand was extracted from the ligand binding domain of the protein and was re-docked into the same position. The conformer obtained on re-docking and the co-crystallized ligand were superimposed and the RMSD between the two was found to be 0.853 angstrom. ADME predictions were also performed for these compounds. Outcomes of the present study have been first utilized to get insight into the molecular feature that promotes bioactivity, and then within screening procedure, have been exploited for the estimation of novel potential antitubulin compounds prior to their synthesis and biological tests.

Synthesis and Structure of Optically Active Oligo(N-substituted-m-benzamide)s Bearing a Bithiophene Chromophore on the Benzene Ring

An optically active oligo(m-benzamide) (OBA1), with a chiral alkyl group on the amide nitrogen and a bithiophene chromophore on the benzene ring by the chain-growth polymerization of methyl 3-((S)-2 ‘-methylbutylamino)-5-(2 ”-(5 ”,2 ”’-bithienyl)) benzoate are prepared. In addition, unimer to trimer model compounds (M1, M2, and M3) are synthesized by the iterative ester hydrolysis and dehydration condensation. An optically active oligo(m-benzamide) with a chiral methoxyethoxyethoxy group (OBA2) is likewise synthesized. On the basis of electronic circular dichroism (CD), UV-vis, and fluorescence spectra, the chiral arrangement of bithiophene chromophores is discussed. By converting the carbonyl group in OBA1 into the methylene group using LiAlH4/AlCl3, a bisignate Cotton effect is collapsed, indicating the importance of the aromatic tertiary amide skeleton for the chiral arrangement of chromophores. The chain conformation of OBA1 is further investigated by means of theoretical CD calculations to figure out that two neighboring bithiophene units are preferentially rotated in a counterclockwise direction.

Domestic cooking methods affect the stability and bioaccessibility of dark purple eggplant (Solanum melongena) phenolic compounds

Eggplant is an important component of the Mediterranean Diet, which becomes edible after cooking. This study determined the fate of dark purple eggplant phenolic compounds after baking, boiling, frying, grilling and digestion. Thirty-seven phenolic compounds were identified and quantified in raw eggplant. Frying determined a 74% increase in total hydroxycinnamic acids whereas a decrease was observed after boiling (27%), grilling (51%), and baking (60%). After digestion, 45%, 33% and 22% of total phenolic compounds resulted bioaccessible in baked, grilled and fried dark purple eggplant. Fried eggplant displayed the highest amount of phenolic compounds (751.46 mg/100 g) after digestion. The cooking methods differently affected the release of individual phenolic compounds. Baking and grilling resulted in higher amount of bioaccessible caffeoylquinic acids whereas frying in di-caffeoylquinic acids and hydroxycinnamic acid-amides. A careful design of the cooking method may be pivotal to modulate the release of specific phenolic compounds.

Catalytic Hydrothermal Liquefaction of Microalgae for Bio-oil Production over Silylated SBA-15 with High Hydrothermal Stability

This paper mainly describes the application of silylated SBA-15 with high hydrothermal stability in catalytic hydrothermal liquefaction (HTL) of Dunaliella (D.) tertiolecta to produce bio-oil. The results indicated that selection of silylation reagent species contributes to improve hydrothermal stability of SBA-15 at 613 K through substituting hydroxyl group on SBA-15 surface. The grafting of silane on SBA-15 had an impact on pore size, wall thickness, specific surface area, pore volume, and other structure characteristics, while not influencing the ordered mesoporous pore structure. When silylated SBA-15 was used as catalyst, D. tertiolecta conversion and bio-oil yield decreased slightly due to adsorption of furan and other compounds on mesoporous structure of SBA-15. Silylated SBA-15 inhibited ammonolysis, Maillard, and other reactions, resulting in decreased acid, ester, amide, and N-containing heterocyclic content in bio-oil. Meanwhile, the content of aldehydes and ketones increases, among which furfural derivatives were the main substances (>70%). Highly selective HTL is realized over silylated SBA-15 with high hydrothermal stability.

The indications of tautomeric conversion in amorphous bicalutamide drug

The investigation of tautomerization phenomenon in pharmaceutically relevant materials has important implications. The lack of knowledge about tautomeric preferences may negatively impact the formulation and manufacturing process as well as performance of drug product. In this paper we performed theoretical calculations to verify the occurrence of proton transfer in popular anti- androgen drug bicalutamide (BIC). Density functional theory (DFT) calculations determine the activation energy values for possible tautomeric paths providing a basis for comparison with experimental data. To find the indication of the presence of imidic acid and amide tautomers in amorphous BIC we applied infrared spectroscopy (IR). Finally, we performed isothermal broadband dielectric spectroscopy studies (BDS) to select the most likely mechanism of proton transfer in supercooled BIC. We found out that thermal processing applied during glass preparation via vitrification method results in the presence of amide and imidic acid forms in glassy BIC. Further heating leads to re-equilibration of supercooled BIC manifested by the growth of viscosity and effective dipole moment. Based on the value of activation energy determined in theoretical and experimental BDS studies we recognized that the observed time evolution of dielectric parameters likely reflects the increasing amount of more stable amide tautomer. The results presented herein indicate that in amorphous BIC in particular conditions the temperature-dependent changes in tautomeric composition due to intramolecular proton transfer are possible.

Enhanced butanol production from ammonium sulfite pretreated wheat straw by separate hydrolysis and fermentation and simultaneous saccharification and fermentation

Wheat straw (WS) was pretreated by ammonium sulfite (AS) for efficient acetone-butanol-ethanol (ABE) production by Clostridium acetobutylicum ATCC 824. Spent liquor containing the amides has the potential to be used for slow-release fertilizer production, and the solid fraction was readily for ABE fermentation. Compared to the results of separate hydrolysis and fermentation (SHF), relative higher ABE titer and yield were achieved in simultaneous saccharification and fermentation (SSF) using different level of AS pretreated WS (6%, 7.5%, 9% and 10.5%, w/v). As biomass loading in SHF increased from 6% to 10.5%, ABE (butanol) titer increased from 12.28 (7.52) to 17.75 (11.25) g/L, with ABE (butanol) yield reducing from 161 (98) to 133 (84) g/kg raw WS. For SSF, the maximum ABE (butanol) titer was obtained from 9% biomass loading. As biomass loading increased from 6% to 9%, ABE (butanol) titer increased from 17.13 (9.50) to 19.83 (12.64) g/L, with ABE (butanol) yield reducing from 224 (1 2 4) to 173 (1 1 0) g/kg raw WS. This study suggested that ABE production by SSF is viable to be conducted using AS pretreated WS.

Successive Protonation of an N-Heterocyclic Imine Derived Carbonyl: Superelectrophilic Dication Versus Masked Acylium Ion

Carbonyl cations are among the most commonly invoked reactive intermediates in organic synthesis. While Olah pioneered superacids to provide a stable ion environment for their study in situ, isolated examples are rare. Here, we disclose successive protonation of an N-heterocyclic imine (NHI) derived carbonyl compound (IDippN)(2)CO, 2, to the monocation [(IDippN)(IDippNH) CO](+), [3](+), and the doubly protonated dication [(IDippNH)(2)CO](2+), [4](2+). [3](+) represents a rare example of an N-protonated carbonyl cation and [4](2+) the first example of a superelectrophilic carbonyl dication. All three compounds have been characterized by X-ray crystallography and IR spectroscopy, revealing stepwise strengthening of the C=O bond on protonation. The unique stability of these systems is attributed to the enhanced basicity and steric profile provided by the NHI substituents. In addition, we report the related singly NHI-stabilized cation [IDippNCO](+), [5](+). Crystallographic and DFT analyses provide insight into the interaction between the carbonyl fragment and the NHI, which reveals that the [CNCO](+) unit (isoelectronic to CCCO) can be described as an acylium cation masked as a cumulene.

Solid-state structure of cyclic dipeptides: an X-ray and computational study of cis- and trans-diketo-piperazines of N-methyl-phenylalanine with the thia-pipecolic acids and thia-prolines

Ten new crystal structures of cis and trans bicyclic diketopiperazines (DKPs) of thia-pipecolic acid (with sulfur in the beta, gamma or delta position) or thia-proline (with sulfur in the beta or gamma position) and N-methyl phenylalanine [(NMe) Phe]: cyclo[(beta-S) Pip-(NMe) Phe], cyclo[(gamma-S) Pip-(NMe) Phe], cyclo[(delta-S) Pip-(NMe) Phe], cyclo[(beta-S) Pro-(NMe) Phe] and cyclo[(beta-S) Pro-(NMe) Phe] were determined with X-ray crystallography. Density functional theory calculations of these molecules in the gas phase succeed in reproducing the observed molecular conformations in the crystal remarkably well. This illustrates the weak to moderate impact of intermolecular packing forces in the absence of classical N-H center dot center dot center dot center dot O hydrogen bonds. The effect of sulfur on the geometry of the DKP ring and details of amide bond non-planarity are discussed. Molecular flexibility of the DKP ring, as estimated from the calculated deformation energies of its endocyclic ring torsion angles, is not in general the decisive factor for the occurrence of multiple symmetry independent molecules in the unit cell (Z’ > 1), though in some cases a correlation is observed.
