In this paper, density functional theory (DFT) study was applied to the absorption of BMSF-BENZ ((4-bromo-7-methoxy-1-(2-methoxyethyl)-5-{[3 (methylsulfonyl)phenyl]methyl)}-2-[4-(propane-2)) yl)phenyl]-1H-1,3-benzothiazole) used for treatment Osteoporosis, on surfaces two types nanocages Zn12O12 and Al12P12. The results showed that interaction with highly exothermic, indicating high chemical ad...

Six new multicomponent solids of 9-ethyladenine and oxalic acid have been detected characterized. The salt screening has performed by mechanochemical solvent crystallization processes. Single crystals the anhydrous salts in 1:1 2:1 nucleobase:coformer molar ratio were obtained solution elucidated single-crystal X-ray analysis. supramolecular interactions observed these studied using density fun...

in the present study, the interactions of three different lithium species li+, li3+ and ch3li with several different sites of the most stable tautomers of dna nucleo-bases are presented. this investigation is based on the results of thermochemical properties, quantum theory of atoms in molecules (qtaim) and natural bond orbital (nbo) analysis, obtained at b3lyp/6-311++g(d,p) level of theory. th...

Herein, a theoretical study on the stability of some vic-dioxime complexes of Ni(II), Pd(II) and Pt(II) in gas and aqueous phases is reported. The DFT/M06/SDD and DFT/M06/6-31G+(d,p) levels of theory were adopted for the metal ions and for every other element respectively. Structural analyses of investigated complexes have revealed square planar geometries stabilized by two O–H⋯Cl hydrogen bond...

The series of substituted 1,2,4-selenodiazolium tetraphenylborate complexes were synthesized via cyclization between 2-pyridylselenylchloride, followed by the anion metathesis, and fully characterized. utilization anion, a strong ?-electron donor its phenyl rings, promoted formation assemblies exhibiting selenium–? interactions. chalcogen bonding (ChB) interactions involving ?-systems studied u...

A theoretical investigation of mono-methyl derivatives closo-borate anions the general form [BnHnCH3]2– (n = 6, 10, 12) and monocarboranes [HCBnHnCH3]− 5, 9, 11) was carried out. An analysis main bonding descriptors exo-polyhedral B–C bonds performed using QTAIM (quantum theory “Atoms in Molecules”), ELF (electron localisation function), NBOs (natural bond orbitals) analyses several other appro...

In this work, we used microwave irradiation conditions to synthesize β-enaminonitrile (4), which was affirmed using single crystal X-ray diffraction and the different spectral data. Two tumor cell lines, MCF-7 MCF-7/ADR, as well two normal HFL-1 WI-38, were assess anticancer activity of compound 4. The studied molecule exhibited potent efficacy against MCF-7/ADR lines compared with reference dr...
