Ab initio calculations of solvent effects on guanine and thioguanine tautomerism
(NATL INST SCIENCE COMMUNICATION-NISCAIR, 2000)The molecular geometries and the relative energies of the ten most stable tautomers of guanine (G1, G2, G3...etc.) and thioguanine (TG1, TG2, TG3...etc.) have been investigated at the HF/3-21G and HF/6-31G** levels in the ... -
Ab Initio Calculations on some Antiepileptic Drugs such as Phenytoin, Phenbarbital, Ethosuximide and Carbamazepine
(SPRINGER/PLENUM PUBLISHERS, 2017)This research deals with some antiepileptic agents that are used to treat antiepileptic seizures. Stable conformational structures corresponding to potential energy minima for each molecule are determined in the gas phase ... -
Ab initio molecular structure study of alkyl substitute analogues of Alzheimer drug phenserine: structure-activity relationships for acetyl- and butyrylcholinesterase inhibitory action
(ELSEVIER SCIENCE BV, 2005)Considerable experimental evidence suggests that phenserine and some alkyl analogues show inhibitory action against human acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). The electronic structure of the newly ... -
Ab initio study of atmospheric reactions of the hydroxyl radical-water complex (OH-H2O) with saturated hydrocarbons (methane, ethane and propane)
(ELSEVIER SCIENCE BV, 2005)Weakly bound reactant and product complexes in the hydrogen abstraction reactions of the hydroxyl radical-water complex (OH-H2O) with CH4, C2H6, and C3H8 were investigated with ab initio molecular orbital methods. Molecular ... -
Ab initio study of the protometric tautomerism of adenine
(1999)Eight tautomers of adenine have been studied by using ab initio theory in the gas phase and in solution. Their stability order has been determined by using the HF/3-21G approximation. The HF/3-21G level calculations predict ... -
Ab initio study on tautomerism of 2-thiouracil in the gas phase and in solution
(KLUWER ACADEMIC PUBL, 2000)Ab initio geometry optimizations were carried out at the HF/3-21G and HF/6-31+G** levels for the six tautomeric forms of 2-thiouracil (2TU, 2TU1, 2TU2, 2TU3, 2TU4, 2TU5) in the gas phase and in solution. To obtain a more ... -
