Stabilities and quantum molecular descriptors of cyclophoshphamide (an anticancer drug)-functionalized (8,0) zigzag and (4,4) armchair carbon nanotubes (CNTs) complexes in water were studied using density functional theory (DFT) calculations. Two attachments namely the sidewall- and tip-attachments are considered for the model constructions. Calculations of the total electronic energy (Et) and ...

Interaction of pure and Vn-doped (8, 0), (12, 0) and (16, 0) boron nitride nanotubes with CO molecules was studied using B3LYP/6-311++G(d) theoretical level. Substituting V instead of B atoms, increased the reactivity of nanotube. From the results, the complex stability depends on the direction and the number of the CO molecules interacted with the nanotube. In this work, the quantum...

the present research has been carried out to study the structure of indexing language databases of irandoc. three databases have been selected as a sample: iranian dissertation abstracts. directory of scientific meetings held in iran. current research in iranian universities and research centers. some descriptors have been selected as a sample for study. to analyze the descriptors checklist was...

Multivariate approaches like principal component analysis (PCA) are powerful tools to investigate hydrophobic descriptors and to discriminate between intrinsic hydrophobicity and polar contributions as hydrogen bonds and other electronic effects. PCA of log P values measured for 37 solutes in eight solventwater systems and of hydrophobic octanol-water substituent constants  for 25 metaand para...

A set of 26 compound of the series halogenated Indole-3-Acetic acids as oxidatively activate prodrugs with potential for targeted cancer therapy were subjected to quantitative structure activity relationship (QSAR) analysis using combination of various electronic, thermodynamic and spatial descriptors. Several statistical regression equations were obtained using multiple regression analysis. QS...
